Best example for getting the Graph API bearer token in SPFX?

[Brent Ellis]

What is the best solution that currently shows how to get the Graph API bearer token from a SharePoint SPFX app?

ADAL.JS doesnt work in the modern Script Editor Web Part by @Mikael Svenson

I want to hopefully re-use my existing Javascript Graph API functions, i just need the best way to get the bearer token, and then muddle through working in my existing functions.

https://dev.office.com/sharepoint/docs/spfx/web-parts/guidance/call-microsoft-graph-from-your-web-pa... or if you can make due with access via Group. permissions, then use GraphHttpClient.

The other option is a server side component to either do ADAL on users behalf, or use app tokens if that works for your scenario.
