The modern developer platform has already moved past the desktop. We’re no longer defined by what’s installed on our laptops, instead we look at what tooling we can use to move from idea to production. An organisations developer platform strategy is no longer a nice to have, it sets the ceiling for what’s possible, an organisation can’t iterate it's way to developer nirvana if the foundation itself is brittle. A great developer platform shrinks TTFC (time to first commit), accelerates release velocity, and maybe most importantly, helps alleviate everyday frictions that lead to developer burnout. Very few platforms deliver everything an organization needs from a developer platform in one product. Modern development spans multiple dimensions, local tooling, cloud infrastructure, compliance, security, cross-platform builds, collaboration, and rapid onboarding. The options organizations face are then to either compromise on one or more of these areas or force developers into rigid environments that slow productivity and innovation. This is where Microsoft Dev Box and GitHub Codespaces come into play. On their own, each addresses critical parts of the modern developer platform: Microsoft Dev Box provides a full, managed cloud workstation. Dev Box gives developers a consistent, high-performance environment while letting central IT apply strict governance and control. Internally at Microsoft, we estimate that usage of Dev Box by our development teams delivers savings of 156 hours per year per developer purely on local environment setup and upkeep. We have also seen significant gains in other key SPACE metrics reducing context-switching friction and improving build/test cycles. Although the benefits of Dev Box are clear in the results demonstrated by our customers it is not without its challenges. The biggest challenge often faced by Dev Box customers is its lack of native Linux support. At the time of writing and for the foreseeable future Dev Box does not support native Linux developer workstations. While WSL2 provides partial parity, I know from my own engineering projects it still does not deliver the full experience. This is where GitHub Codespaces comes into this story. GitHub Codespaces delivers instant, Linux-native environments spun up directly from your repository. It’s lightweight, reproducible, and ephemeral ideal for rapid iteration, PR testing, and cross-platform development where you need Linux parity or containerized workflows. Unlike Dev Box, Codespaces can run fully in Linux, giving developers access to native tools, scripts, and runtimes without workarounds. It also removes much of the friction around onboarding: a new developer can open a repository and be coding in minutes, with the exact environment defined by the project’s devcontainer.json. That said, Codespaces isn’t a complete replacement for a full workstation. While it’s perfect for isolated project work or ephemeral testing, it doesn’t provide the persistent, policy-controlled environment that enterprise teams often require for heavier workloads or complex toolchains. Used together, they fill the gaps that neither can cover alone: Dev Box gives the enterprise-grade foundation, while Codespaces provides the agile, cross-platform sandbox. For organizations, this pairing sets a higher ceiling for developer productivity, delivering a truly hybrid, agile and well governed developer platform. Better Together: Dev Box and GitHub Codespaces in action Together, Microsoft Dev Box and GitHub Codespaces deliver a hybrid developer platform that combines consistency, speed, and flexibility. Teams can spin up full, policy-compliant Dev Box workstations preloaded with enterprise tooling, IDEs, and local testing infrastructure, while Codespaces provides ephemeral, Linux-native environments tailored to each project. One of my favourite use cases is having local testing setups like a Docker Swarm cluster, ready to go in either Dev Box or Codespaces. New developers can jump in and start running services or testing microservices immediately, without spending hours on environment setup. Anecdotally, my time to first commit and time to delivering “impact” has been significantly faster on projects where one or both technologies provide local development services out of the box. Switching between Dev Boxes and Codespaces is seamless every environment keeps its own libraries, extensions, and settings intact, so developers can jump between projects without reconfiguring or breaking dependencies. The result is a turnkey, ready-to-code experience that maximizes productivity, reduces friction, and lets teams focus entirely on building, testing, and shipping software. To showcase this value, I thought I would walk through an example scenario. In this scenario I want to simulate a typical modern developer workflow. Let's look at a day in the life of a developer on this hybrid platform building an IOT project using Python and React. Spin up a ready-to-go workstation (Dev Box) for Windows development and heavy builds. Launch a Linux-native Codespace for cross-platform services, ephemeral testing, and PR work. Run "local" testing like a Docker Swarm cluster, database, and message queue ready to go out-of-the-box. Switch seamlessly between environments without losing project-specific configurations, libraries, or extensions. 9:00 AM – Morning Kickoff on Dev Box I start my day on my Microsoft Dev Box, which gives me a fully-configured Windows environment with VS Code, design tools, and Azure integrations. I select my teams project, and the environment is pre-configured for me through the Dev Box catalogue. Fortunately for me, its already provisioned. I could always self service another one using the "New Dev Box" button if I wanted too. I'll connect through the browser but I could use the desktop app too if I wanted to. My Tasks are: Prototype a new dashboard widget for monitoring IoT device temperature. Use GUI-based tools to tweak the UI and preview changes live. Review my Visio Architecture. Join my morning stand up. Write documentation notes and plan API interactions for the backend. In a flash, I have access to my modern work tooling like Teams, I have this projects files already preloaded and all my peripherals are working without additional setup. Only down side was that I did seem to be the only person on my stand up this morning? Why Dev Box first: GUI-heavy tasks are fast and responsive. Dev Box’s environment allows me to use a full desktop. Great for early-stage design, planning, and visual work. Enterprise Apps are ready for me to use out of the box (P.S. It also supports my multi-monitor setup). I use my Dev Box to make a very complicated change to my IoT dashboard. Changing the title from "IoT Dashboard" to "Owain's IoT Dashboard". I preview this change in a browser live. (Time for a coffee after this hardwork). The rest of the dashboard isnt loading as my backend isnt running... yet. 10:30 AM – Switching to Linux Codespaces Once the UI is ready, I push the code to GitHub and spin up a Linux-native GitHub Codespace for backend development. Tasks: Implement FastAPI endpoints to support the new IoT feature. Run the service on my Codespace and debug any errors. Why Codespaces now: Linux-native tools ensure compatibility with the production server. Docker and containerized testing run natively, avoiding WSL translation overhead. The environment is fully reproducible across any device I log in from. 12:30 PM – Midday Testing & Sync I toggle between Dev Box and Codespaces to test and validate the integration. I do this in my Dev Box Edge browser viewing my codespace (I use my Codespace in a browser through this demo to highlight the difference in environments. In reality I would leverage the VSCode "Remote Explorer" extension and its GitHub Codespace integration to use my Codespace from within my own desktop VSCode but that is personal preference) and I use the same browser to view my frontend preview. I update the environment variable for my frontend that is running locally in my Dev Box and point it at the port running my API locally on my Codespace. In this case it was a web socket connection and HTTPS calls to port 8000. I can make this public by changing the port visibility in my Codespace. https://fluffy-invention-5x5wp656g4xcp6x9-8000.app.github.dev/api/devices wss://fluffy-invention-5x5wp656g4xcp6x9-8000.app.github.dev/ws This allows me to: Preview the frontend widget on Dev Box, connecting to the backend running in Codespaces. Make small frontend adjustments in Dev Box while monitoring backend logs in Codespaces. Commit changes to GitHub, keeping both environments in sync and leveraging my CI/CD for deployment to the next environment. We can see the Dev Box running local frontend and the Codespace running the API connected to each other, making requests and displaying the data in the frontend! Hybrid advantage: Dev Box handles GUI previews comfortably and allows me to live test frontend changes. Codespaces handles production-aligned backend testing and Linux-native tools. Dev Box allows me to view all of my files in one screen with potentially multiple Codespaces running in browser of VS Code Desktop. Due to all of those platform efficiencies I have completed my days goals within an hour or two and now I can spend the rest of my day learning about how to enable my developers to inner source using GitHub CoPilot and MCP (Shameless plug). The bottom line There are some additional considerations when architecting a developer platform for an enterprise such as private networking and security not covered in this post but these are implementation details to deliver the described developer experience. Architecting such a platform is a valuable investment to deliver the developer platform foundations we discussed at the top of the article. While in this demo I have quickly built I was working in a mono repository in real engineering teams it is likely (I hope) that an application is built of many different repositories. The great thing about Dev Box and Codespaces is that this wouldn’t slow down the rapid development I can achieve when using both. My Dev Box would be specific for the project or development team, pre loaded with all the tools I need and potentially some repos too! When I need too I can quickly switch over to Codespaces and work in a clean isolated environment and push my changes. In both cases any changes I want to deliver locally are pushed into GitHub (Or ADO), merged and my CI/CD ensures that my next step, potentially a staging environment or who knows perhaps *Whispering* straight into production is taken care of. Once I’m finished I delete my Codespace and potentially my Dev Box if I am done with the project, knowing I can self service either one of these anytime and be up and running again! Now is there overlap in terms of what can be developed in a Codespace vs what can be developed in Azure Dev Box? Of course, but as organisations prioritise developer experience to ensure release velocity while maintaining organisational standards and governance then providing developers a windows native and Linux native service both of which are primarily charged on the consumption of the compute* is a no brainer. There are also gaps that neither fill at the moment for example Microsoft Dev Box only provides windows compute while GitHub Codespaces only supports VS Code as your chosen IDE. It's not a question of which service do I choose for my developers, these two services are better together! *Changes have been announced to Dev Box pricing. A W365 license is already required today and dev boxes will continue to be managed through Azure.

From "Built" to "Deployed" in Minutes You've just finished building something great: A marketing landing page for your startup A portfolio site showcasing your work A documentation site for your open-source project An e-commerce storefront built with Next.js An internal dashboard for your team A blog with your latest content Now you want to share it with the world. Azure Static Web Apps offers free hosting, global CDN, custom domains, and built-in auth—but figuring out the deployment workflow can slow you down. The learning curve: "What's the CLI command again? Is it swa-cli or @azure/static-web-apps-cli? Where does staticwebapp.config.json go?" The golden path: "Hey Copilot, deploy my Vite app to Azure Static Web Apps" The skill provides a streamlined, tested workflow—the golden path—so you can focus on your app, not the deployment process. What Are Agent Skills? Agent Skills are self-contained knowledge bundles that enhance GitHub Copilot's capabilities for specialized tasks. They provide a curated, golden path for common workflows: Feature Benefit Curated Commands Exact CLI syntax that works today Guardrails Knows what NOT to do (e.g., never manually create swa-cli.config.json) Troubleshooting Built-in solutions for common errors Framework Awareness Knows Vite uses port 5173, React uses 3000 The Traditional Approach: Learning as You Go Deploying to Azure Static Web Apps is straightforward once you know the workflow, but the learning curve can add time to your first deployment: Typical First-Time Challenges Finding the right tools: Azure has multiple CLI options—the Azure CLI extension (az staticwebapp) for managing resources, and the SWA CLI (@azure/static-web-apps-cli) for local development and deployment. Knowing which to use when takes research. Configuration decisions: Where does staticwebapp.config.json go? Should you use swa init or create configs manually? What's the right build output path for your framework? Framework-specific setup: Different frameworks have different port numbers, build commands, and output directories. Vite uses port 5173, Create React App uses 3000, Next.js has its own conventions. SPA routing: Client-side routing needs navigationFallback configuration—something you might not discover until you see 404 errors in production. Typical First Deployment: 25-45 minutes This time includes reading documentation, trying commands, and troubleshooting configuration. Not wrong—just a learning process that the skill can accelerate. The Golden Path: With the Azure Static Web Apps Skill The skill provides a streamlined workflow that guides you through each step—whether you're deploying a portfolio, marketing site, or enterprise application: Step 1: Install and Initialize (30 seconds) You: "Set up my Vite React app for Azure Static Web Apps" Copilot (with skill): "I'll help you set up SWA for your Vite app: 1.

Developers burn cycles context‑switching: opening five repos to find a logging example, searching a wiki for a data masking rule, scrolling chat history for the latest pipeline pattern. Organisations that I speak to are often on the path of transformational platform engineering projects but always have the fear or doubt of "what if my engineers don't use these resources". While projects like Backstage still play a pivotal role in inner sourcing and discoverability I also empathise with developers who would argue "How would I even know in the first place, which modules have or haven't been created for reuse". In this blog we explore how we can ensure organisational standards and developer satisfaction without any heavy lifting on either side, no custom model training, no rewriting or relocating of repositories and no stagnant local data. Using GitHub Copilot + Azure DevOps MCP server (with the free `code_search` extension) we turn the IDE into an organizational knowledge interface. Instead of guessing or re‑implementing, engineers can start scaffolding projects or solving issues as they would normally (hopefully using Copilot) and without extra prompting. GitHub Copilot can lean into organisational standards and ensure recommendations are made with code snippets directly generated from existing examples. What Is the Azure DevOps MCP Server + code_search Extension? MCP (Model Context Protocol) is an open standard that lets agents (like GitHub Copilot) pull in structured, on-demand context from external systems. MCP servers contain natural language explanations of the tools that the agent can utilise allowing dynamic decision making of when to implement certain toolsets over others. The Azure DevOps MCP Server is the ADO Product Team's implementation of that standard. It exposes your ADO environment in a way Copilot can consume. Out of the box it gives you access to: Projects – list and navigate across projects in your organization. Repositories – browse repos, branches, and files. Work items – surface user stories, bugs, or acceptance criteria. Wiki's – pull policies, standards, and documentation. This means Copilot can ground its answers in live ADO content, instead of hallucinating or relying only on what’s in the current editor window. The ADO server runs locally from your own machine to ensure that all sensitive project information remains within your secure network boundary. This also means that existing permissions on ADO objects such as Projects or Repositories are respected. Wiki search tooling available out of the box with ADO MCP server is very useful however if I am honest I have seen these wiki's go unused with documentation being stored elsewhere either inside the repository or in a project management tool. This means any tool that needs to implement code requires the ability to accurately search the code stored in the repositories themself. That is where the code_search extension enablement in ADO is so important. Most organisations have this enabled already however it is worth noting that this pre-requisite is the real unlock of cross-repo search. This allows for Copilot to: Query for symbols, snippets, or keywords across all repos. Retrieve usage examples from code, not just docs. Locate standards (like logging wrappers or retry policies) wherever they live. Back every recommendation with specific source lines. In short: MCP connects Copilot to Azure DevOps. code_search makes that connection powerful by turning it into a discovery engine. What is the relevance of Copilot Instructions? One of the less obvious but most powerful features of GitHub Copilot is its ability to follow instructions files. Copilot automatically looks for these files and uses them as a “playbook” for how it should behave. There are different types of instructions you can provide: Organisational instructions – apply across your entire workspace, regardless of which repo you’re in. Repo-specific instructions – scoped to a particular repository, useful when one project has unique standards or patterns. Personal instructions – smaller overrides layered on top of global rules when a local exception applies. (Stored in .github/copilot-instructions.md) In this solution, I’m using a single personal instructions file. It tells Copilot: When to search (e.g., always query repos and wikis before answering a standards question). Where to look (Azure DevOps repos, wikis, and with code_search, the code itself). How to answer (responses must cite the repo/file/line or wiki page; if no source is found, say so). How to resolve conflicts (prefer dated wiki entries over older README fragments). As a small example, a section of a Copilot instruction file could look like this: # GitHub Copilot Instructions for Azure DevOps MCP Integration This project uses Azure DevOps with MCP server integration to provide organizational context awareness. Always check to see if the Azure DevOps MCP server has a tool relevant to the user's request. ## Core Principles ### 1. Azure DevOps Integration - **Always prioritize Azure DevOps MCP tools** when users ask about: - Work items, stories, bugs, tasks - Pull requests and code reviews - Build pipelines and deployments - Repository operations and branch management - Wiki pages and documentation - Test plans and test cases - Project and team information ### 2. Organizational Context Awareness - Before suggesting solutions, **check existing organizational patterns** by: - Searching code across repositories for similar implementations - Referencing established coding standards and frameworks - Looking for existing shared libraries and utilities - Checking architectural decision records (ADRs) in wikis ### 3. Cross-Repository Intelligence - When providing code suggestions: - **Search for existing patterns** in other repositories first - **Reference shared libraries** and common utilities - **Maintain consistency** with organizational standards - **Suggest reusable components** when appropriate ## Tool Usage Guidelines ### Work Items and Project Management When users mention bugs, features, tasks, or project planning: ``` ✅ Use: wit_my_work_items, wit_create_work_item, wit_update_work_item ✅ Use: wit_list_backlogs, wit_get_work_items_for_iteration ✅ Use: work_list_team_iterations, core_list_projects The result... To test this I created 3 ADO Projects each with between 1-2 repositories. The repositories were light with only ReadMe's inside containing descriptions of the "repo" and some code snippets examples for usage. I have then created a brand-new workspace with no context apart from a Copilot instructions document (which could be part of a repo scaffold or organisation wide) which tells Copilot to search code and the wikis across all ADO projects in my demo environment. It returns guidance and standards from all available repo's and starts to use it to formulate its response. In the screenshot I have highlighted some key parts with red boxes. The first being a section of the readme that Copilot has identified in its response, that part also highlighted within CoPilot chat response. I have highlighted the rather generic prompt I used to get this response at the bottom of that window too. Above I have highlighted Copilot using the MCP server tooling searching through projects, repo's and code. Finally the largest box highlights the instructions given to Copilot on how to search and how easily these could be optimised or changed depending on the requirements and organisational coding standards. How did I implement this? Implementation is actually incredibly simple. As mentioned I created multiple projects and repositories within my ADO Organisation in order to test cross-project & cross-repo discovery. I then did the following: Enable code_search - in your Azure DevOps organization (Marketplace → install extension). Login to Azure - Use the AZ CLI to authenticate to Azure with "az login". Create vscode/mcp.json file - Snippet is provided below, the organisation name should be changed to your organisations name. Start and enable your MCP server - In the mcp.json file you should see a "Start" button. Using the snippet below you will be prompted to add your organisation name. Ensure your Copilot agent has access to the server under "tools" too. View this setup guide for full setup instructions (azure-devops-mcp/docs/GETTINGSTARTED.md at main · microsoft/azure-devops-mcp) Create a Copilot Instructions file - with a search-first directive. I have inserted the full version used in this demo at the bottom of the article. Experiment with Prompts – Start generic (“How do we secure APIs?”). Review the output and tools used and then tailor your instructions. Considerations While this is a great approach I do still have some considerations when going to production. Latency - Using MCP tooling on every request will add some latency to developer requests. We can look at optimizing usage through copilot instructions to better identify when Copilot should or shouldn't use the ADO MCP server. Complex Projects and Repositories - While I have demonstrated cross project and cross repository retrieval my demo environment does not truly simulate an enterprise ADO environment. Performance should be tested and closely monitored as organisational complexity increases. Public Preview - The ADO MCP server is moving quickly but is currently still public preview. We have demonstrated in this article how quickly we can make our Azure DevOps content discoverable. While their are considerations moving forward this showcases a direction towards agentic inner sourcing. Feel free to comment below how you think this approach could be extended or augmented for other use cases!

Discovery First Before providing solutions, always discover organizational context: ``` "Let me first check what patterns exist in your organization..." → Search code, check repositories, review existing work items ``` ### 2. Reference Organizational Standards When suggesting code or approaches: ``` "Based on patterns I found in your [RepositoryName] repository..." "Following your organization's standard approach seen in..." "This aligns with the pattern established in [TeamName]'s implementation..." ``` ### 3. Actionable Integration Always offer to create or update Azure DevOps artifacts: ``` "I can create a work item for this enhancement..." "Should I update the wiki page with this new pattern?" "Let me link this to the current iteration..." ``` ## Specific Scenarios ### New Feature Development 1. **Search existing repositories** for similar features 2. **Check architectural patterns** and shared libraries 3. **Review related work items** and planning documents 4. **Suggest implementation** based on organizational standards 5. **Offer to create work items** and documentation ### Bug Investigation 1. **Search for similar issues** across repositories and work items 2. **Check related builds** and recent changes 3. **Review test results** and failure patterns 4. **Provide solution** based on organizational practices 5. **Offer to create/update** bug work items and documentation ### Code Review and Standards 1. **Compare against organizational patterns** found in other repositories 2. **Reference coding standards** from wiki documentation 3. **Suggest improvements** based on established practices 4. **Check for reusable components** that could be leveraged ### Documentation Requests 1. **Search existing wikis** for related content 2. **Check for ADRs** and technical documentation 3. **Reference patterns** from similar projects 4. **Offer to create/update** wiki pages with findings ## Error Handling If Azure DevOps MCP tools are not available or fail: 1. **Inform the user** about the limitation 2. **Provide alternative approaches** using available information 3. **Suggest manual steps** for Azure DevOps integration 4. **Offer to help** with configuration if needed ## Best Practices ### Always Do: - ✅ Search organizational context before suggesting solutions - ✅ Reference existing patterns and standards - ✅ Offer to create/update Azure DevOps artifacts - ✅ Maintain consistency with organizational practices - ✅ Provide actionable next steps ### Never Do: - ❌ Suggest solutions without checking organizational context - ❌ Ignore existing patterns and implementations - ❌ Provide generic advice when specific organizational context is available - ❌ Forget to offer Azure DevOps integration opportunities --- **Remember: The goal is to provide intelligent, context-aware assistance that leverages the full organizational knowledge base available through Azure DevOps while maintaining development efficiency and consistency.**Deploying a Bun + Hono + Vite app to Azure App Service
TOC Introduction Local Environment Deployment Conclusion 1. Introduction Anthropic, the company behind Claude, recently acquired the JavaScript runtime startup Bun, marking one of the most significant shifts in the modern JavaScript ecosystem since the arrival of Node.js and Deno. This acquisition signals more than a business move, it represents a strategic consolidation of performance-oriented tooling, developer ergonomics, and the future of AI-accelerated software development. At the center of this momentum lies a powerful trio: Bun, Hono, and Vite. Bun is a next-generation JavaScript runtime that reimagines everything from dependency installation to HTTP servers, bundling, and execution speed. On top of Bun, frameworks like Hono provide an elegant, lightweight approach to building APIs and full web applications. Hono embraces the Web Standard API model while optimizing for speed and minimal footprint. For front-end development, Vite completes the trio. Vite provides lightning-fast local development through native ES modules and an optimized build pipeline. When paired with Bun, the developer experience becomes even smoother, as Bun accelerates not only the dev server but also the entire build process. The result is a full-stack workflow where front-end and back-end both benefit from a consistent, high-performance environment. This article will guide you through deploying a Bun + Hono + Vite application to an Azure Linux Web App. 2. Local Environment The development environment used in this example is a Docker container. All project creation, modification, and testing will take place inside this environment. We will build an application using Bun + Hono + Vite, containing three endpoints: / : The root endpoint, which displays Hello Bun Hono Vite /api/hello : A static endpoint /api/backend : A runtime endpoint executed on the server, returning computed results for the frontend to display Create the Docker development environment This command generates a Bun + Hono + Vite project. docker run --rm -it -v "$PWD":/app -w /app oven/bun:latest bunx create-vite . --template vanilla-ts Follow the prompts as shown in the image and make the appropriate selections. After completing the prompts, the corresponding project files will be created. At this point, you may press Ctrl + C to stop the running Bun server. Next, install Hono: docker run --rm -it -v "$PWD":/app -w /app oven/bun:latest bun add hono Create 4 files and edit 2 files Create .vscode/settings.json This file serves two purposes: To prevent the large node_modules folder from being uploaded during deployment. Uploading it wastes bandwidth and may cause compatibility issues between local and production environments. To disable ORYX BUILD from interfering in the deployment process. We will use a custom startup script to handle all build tasks instead. { "appService.zipIgnorePattern": [ "node_modules{,/**}", ".git{,/**}", ".vscode{,/**}" ], "appService.showBuildDuringDeployPrompt": false } Create vite.config.ts This file configures Vite’s base path to use relative paths instead of absolute paths. Although this does not affect the production environment, it is essential locally when URLs and ports may differ. import { defineConfig } from 'vite'; export default defineConfig({ base: './', }); Create server.ts This file configures backend routing using Hono and sets up the Bun server. It includes several test endpoints, some static, and some executed at runtime. import { Hono } from 'hono'; import { serveStatic } from 'hono/bun'; const app = new Hono(); app.get('/api/hello', (c) => { return c.text('this is api/hello'); }); app.get('/api/backend', (c) => { const result = 1 + 1; return c.json({ message: "this is /api/backend", calc: `1 + 1 = ${result}`, value: result, }); }); app.use('/assets/*', serveStatic({ root: './dist' })); app.use('/*', serveStatic({ root: './dist' })); app.get('/', serveStatic({ path: './dist/index.html' })); const port = Number(process.env.PORT ?? 3000); export default { port, fetch: app.fetch, }; Create startup.sh This script serves several important roles: Remove any node_modules folders or tar archives created by ORYX during deployment Install the Bun runtime Fully take over the ORYX build process Start the Bun server as the final step #!/bin/bash set -e echo "===== Startup script running =====" cd /home/site/wwwroot echo "Cleaning up Oryx-generated node_modules..." if [ -d /node_modules ]; then echo "Removing /node_modules ..." rm -rf /node_modules fi if [ -f node_modules.tar.gz ]; then echo "Removing node_modules.tar.gz ..." rm -f node_modules.tar.gz fi echo "Oryx cleanup complete." export BUN_INSTALL=/home/site/wwwroot/.bun export PATH="$BUN_INSTALL/bin:/home/site/wwwroot/node_modules/.bin:$PATH" export NODE_PATH="/home/site/wwwroot/node_modules" if [ ! -f "$BUN_INSTALL/bin/bun" ]; then echo "Bun not found.

Deployment We create a Linux Web App with a minimum SKU of Premium. Add Environment Variables SCM_DO_BUILD_DURING_DEPLOYMENT=false Purpose: Prevents the deployment environment from packaging during publish. This must also be set in the deployment environment itself. WEBSITE_RUN_FROM_PACKAGE=false Purpose: Instructs Azure Web App not to run the app from a prepackaged file. ENABLE_ORYX_BUILD=false Purpose: Prevents Azure Web App from building after deployment. All build tasks will instead execute during the startup script. Add Startup Command bash /home/site/wwwroot/startup.sh After that, we can return to VS Code and deploy the project. Once the deployment is complete, wait about five minutes for the build process to finish, and then you can begin testing. / /api/hello /api/backend 4. Conclusion Bun + Hono + Vite form a cohesive ecosystem that embodies the next era of JavaScript development: fast, compact, ergonomic, and deeply aligned with modern infrastructure needs. It is particularly well-suited for AI applications, where latency, concurrency, and rapid iteration matter more than ever. From streaming inference endpoints to vector database integrations, this stack offers the responsiveness and scalability essential for AI-powered systems.
Unlocking Client-Side Configuration at Scale with Azure App Configuration and Azure Front Door
As modern apps shift more logic to the browser, Azure App Configuration now brings dynamic configuration directly to client-side applications. Through its integration with Azure Front Door, developers can deliver configuration to thousands or millions of clients with CDN-scale performance while avoiding the need to expose secrets or maintain custom proxy layers. This capability is especially important for AI-powered and agentic client applications, where model settings and behaviors often need to adjust rapidly and safely. This post introduces the new capability, what it unlocks for developers, and how to start building dynamic, configuration-driven client experiences in Azure. App Configuration for Client Applications Centralized Settings and Feature Management App Configuration gives developers a single, consistent place to define configuration settings and feature flags. Until now, this capability was used almost exclusively by server-side applications. With Azure Front Door integration, these same settings can now power modern client experiences across: Single Page Applications (React, Vue, Angular, Next.js, and others using JavaScript) Mobile/ and desktop applications with .Net MAUI JavaScript-powered UI components or embedded widgets running in browser Any browser-based application that can run JavaScript This allows developers to update configuration without redeploying the client app. CDN-Accelerated Configuration Delivery with Azure Front Door Azure Front Door enables client applications to fetch configuration using a fast, globally distributed CDN path. Developers benefit from: High-scale configuration delivery to large client populations Edge caching for fast, low-latency configuration retrieval Reduced load on your backend configuration store through CDN offloading Dedicated endpoint that exposes only the configuration subset it is scoped for. Secure and Scalable Architecture App Configuration integrates with Azure Front Door to deliver configuration to client-side apps using a simple, secure, and CDN-accelerated flow. How it works The browser calls Azure Front Door anonymously, like any CDN asset. Front Door uses managed identity to access App Configuration securely. Only selected key-values, feature flags or snapshots are exposed through Azure Front Door. No secrets or credentials are shipped to the client. Edge caching enables high throughput and low latency configuration delivery. This provides a secure and efficient design for client applications and eliminates the need for custom gateway code or proxy services. Developer Scenarios: What You Can Build CDN-delivered configuration unlocks a range of rich client application scenarios: Client-side feature rollouts for UI components A/B testing or targeted experiences using feature flags Control AI/LLM model parameters and UI behaviors through configuration Dynamically control client-side agent behavior, safety modes, and guardrail settings through configuration Consistent behavior for clients using snapshot-based configuration references These scenarios previously required custom proxies. Now, they work out-of-the-box with Azure App Configuration + Azure Front Door. End-to-End Developer Journey The workflow for enabling client-side configuration with App Configuration is simple: Define key values or feature flags in Azure App Configuration Connect App Configuration to Azure Front Door in the portal Scope configuration exposed by Front Door endpoint with key value or snapshot filter. Use the updated AppConfig JavaScript or .NET provider to connect to Front Door anonymously. Client app fetches configuration via Front Door with CDN performance Update your configuration centrally, no redeployment required To see this workflow end-to-end, check out this demo video. The video shows how to connect an App Configuration store to Azure Front Door and use the Front Door endpoint in a client application. It also demonstrates dynamic feature flag refresh as updates are made in the store. Portal Experience to connect Front Door Once you create your App Configuration store with key values and/or feature flags, you can configure the Front Door connection directly in the Azure portal. The App Configuration portal guides you through connecting a profile, creating an endpoint, and scoping which keys, labels, or snapshots will be exposed to client applications. A detailed “How-To” guide is available in the App Configuration documentation. Using the Front Door Endpoint in Client Applications JavaScript Provider Minimum version for this feature is 2.3.0-preview, get the provider from here. Add below snippet in your code to fetch the key values and/or feature flags from App Configuration through front door. import { loadFromAzureFrontDoor } from "@azure/app-configuration-provider"; const appConfig = await loadFromAzureFrontDoor("https://<your-afd-endpoint>", { featureFlagOptions: { enabled: true }, }); const yoursetting = appConfig.get("<app.yoursetting>"); .NET Provider Minimum version supporting this feature is 8.5.0-preview, get the provider from here builder.Configuration.AddAzureAppConfiguration(options => { options.ConnectAzureFrontDoor(new Uri("https://<your-afd-endpoint>")) .UseFeatureFlags(featureFlagOptions => { featureFlagOptions.Select("<yourappprefix>"); }); }); See our GitHub samples for JavaScript and .NET MAUI for complete client application setups. Notes & Limitations Feature flag scoping requires two key prefix filters, startsWith(".appconfig.featureflag") and ALL keys. Portal Telemetry feature does not reflect client-side consumption yet. This feature is in preview, and currently not supported in Azure sovereign clouds. Conclusion By combining Azure App Configuration with Azure Front Door, developers can now power a new generation of dynamic client applications. Configuration is delivered at CDN speed, securely and at scale letting you update experiences instantly, without redeployment or secret management on client side. This integration brings App Configuration’s flexibility directly to the browser, making it easier to power AI-driven interfaces, agentic workflows, and dynamic user experiences. Try client-side configuration with App Configuration today and update your apps’ behavior in real time, without any redeployments.AI Career Navigator — Empowering Job Seekers with Azure OpenAI

Understanding 'Always On' vs. Health Check in Azure App Service
The 'Always On' feature in Azure App Service helps keep your app warm by ensuring it remains running and responsive, even during periods of inactivity with no incoming traffic. As this feature pings to root URI after every 5 minutes. On Other hand Health-check feature helps pinging configured path every minute to monitor the application availability on each instance. What is 'Always On' in Azure App Service? The Always On feature ensures that the host process of your web app stays running continuously. This results in better responsiveness after idle periods since the app doesn’t need to cold boot when a request arrives. How to enable Always On: Navigate to the Azure Portal and open your Web App. Go to Configuration > General Settings. Toggle Always On to On. What is Health Check in Azure App Service? Health check increases your application's availability by rerouting requests away from instance where application is marked unhealthy and replacing instances if they remain unhealthy. How to enable Health-Check: Navigate to the Azure Portal and open your Web App. Under Monitoring, select Health check. Select Enable and provide a valid URL path for your application, such as /health or /api/health. Select Save. So, is it still necessary to enable the 'Always On' feature when Health Check is already pinging your application every minute? -> Yes, please find below explanation for the same. Test App scenario: Health Check enabled (pointing to /health_check path) and Always On disabled. Started the app and sent some user requests. Observations from the Test: After the application starts up, health check pings begin following the end user's request. Please find below table representing Health-check pings following user's request to root URI. Time Bucket URL Status Request Count 2025-03-20 07:00:00.0000000 / 200 6 2025-03-20 07:00:00.0000000 /health_check 200 30 2025-03-20 07:30:00.0000000 /health_check 200 30 Subsequent Health-check pings will continue, even in the absence of user requests. However, after restarting the app and in the absence of any user requests, we observed that Health Check requests were not initiated. This indicates that Health Check does not start automatically unless application is actively running and serving requests. Conclusion: Always On ensures that the app is proactively kept warm by sending root URI pings, even post-restart. The health-check feature is useful for monitoring application availability when the application is active. However, after a restart, if the application isn't active due to a lack of requests, Health-check pings won't initiate. Therefore, it is highly recommended to enable Always On, particularly for applications that need continuous availability and to avoid application process unload events. Recommendation: Enable Always On alongside Health Check to ensure optimal performance and reliability.Self Hosted AI Application on AKS in a day with KAITO and CoPilot.
In this blog post I document my experience of spending a full day using KAITO and Copilot to accelerate deployment and development of a self managed AI enabled chatbot deployed in a managed cluster. The goal is to showcase how quickly using a mix of AI tooling we can go from zero to a self hosted, tuned LLM and chatbot application. At the top of this article I want to share my perspective on the future of projects such as KAITO. At the moment I believe KAITO to be somewhat ahead of its time, as most enterprises begin adopting abstracted artificial intelligence it is brilliant to see projects like KAITO being developed ready for the eventual abstraction pendulum to swing back, motivated by usual factors such as increased skills in the market, cost and governance. Enterprises will undoubtedly in the future look to take centralised control of the AI models being used by their enterprises as GPU's become cheaper, more readily available and powerful. When this shift happens open source projects like KAITO will become common place in enterprises. It is also my opinion that Kubernetes lends itself perfectly to be the AI platform of the future a position shared by the CNCF (albeit both sources here may be somewhat biased). The resiliency, scaling and existence of Kuberentes primitives such as "Jobs" mean that Kubernetes is already the de-facto platform for machine learning training and inference. These same reasons also make Kuberentes the best underlying platform for AI development. Companies including DHL, Wayve and even OpenAI all run ML or AI workloads already on Kubernetes. That does not mean that Data Scientists and engineers will suddenly be creating Dockerfiles or exploring admission controllers, Kubernetes instead, as a platform will be multiple layers of abstraction away (Full scale self service platform engineering) however the engineers responsible for running and operating the platform will hail projects like KAITO.
