Accessing a deployed NodeJS app?

You deployed an Azure Function App, which runs in API mode by default, not a normal static website, so you cannot directly access index.js.

Try this URL to access your function:

https://blahblah-func-70.azurewebsites.net/api/index

If it is 404, go to Azure Portal to see if there is a correct trigger under Functions, such as the function name index. If it is an HTTP trigger, it should be accessible. If not, check the route configuration in function.json, you may need to adjust the path.

Or directly cat index.js in Kudu to see how context.res handles requests in the code!

Try this:

Create an HTTP Trigger: In your index.js file, you need to define an HTTP-triggered function:

module.exports = async function (context, req) {
    context.log('HTTP trigger function processed a request.');

    const name = (req.query.name || (req.body && req.body.name));
    const responseMessage = name
        ? `Hello, ${name}. This HTTP triggered function executed successfully.`
        : "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response.";

    context.res = {
        // status: 200, /* Defaults to 200 */
        body: responseMessage
    };
};

Configure function.json: Ensure you have a function.json file in the same directory as your index.js file:

{
    "bindings": [
        {
            "authLevel": "function",
            "type": "httpTrigger",
            "direction": "in",
            "name": "req",
            "methods": ["get", "post"]
        },
        {
            "type": "http",
            "direction": "out",
            "name": "res"
        }
    ]
}

• Deploy Your Function: Make sure your function is deployed to Azure. You can do this using the Azure CLI, Visual Studio Code, or directly from the Azure portal.
• Access Your Function: Once deployed, you can access your function using the URL format: https://<your-function-app-name>.azurewebsites.net/api/<function-name>. For example, if your function app name is blahblah-func-70 and your function name is HttpTrigger1, the URL would be https://blahblah-func-70.azurewebsites.net/api/HttpTrigger1.
