Questions and discussions about using the Shopify CLI and Shopify-built libraries.
In the page explaining how to get started with AppBridge, we have examples of using AppBridge form CDN.
https://shopify.dev/apps/tools/app-bridge/getting-started
That is how we are using AppBridge.
However, in the page that describes how to use getSessionToken, there is no example on usage with CDN hosted AppBridge.
https://shopify.dev/apps/auth/session-tokens/axios
Could you give us examples on how to use getSessionToken from CDN hosted AppBridge?
All of our CDN packages will be globally namespaced under their package name. In this case you can access them like so:
const getSessionToken = window['app-bridge-utils'].getSessionToken;
The rest of the example should be the same

This must not be correct. I am getting
Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'getSessionToken')
The code I have is as follows, and I am getting the error when calling
const getSessionToken = window['app-bridge-utils'].getSessionToken;

Found the solution! Actually, someone else found it. In this thread: https://community.shopify.com/c/shopify-apis-and-sdks/getting-app-bridge-session-token-using-plain-j...
It's in a different file:
<script src="https://unpkg.com/@shopify/app-bridge-utils@2"></script>
window['app-bridge-utils'].getSessionToken(app).then(token => ...)
app-bridge-utils looks like it has been deprecated because the utils moved into a utilities directory in app-bridge.
Can we get an example of how to use getSessionToken or authenticatedFetch from that sub-directory through the CDN-hosted approach? It does not seem as simple as
const authenticatedFetch = window["app-bridge"].utilities.authenticatedFetch
const authenticatedFetch = window["app-bridge"].utilities.authenticatedFetch(app)
This is an update since app-bridge-utils is deprecated.
Then you can use the const authenticatedFetch just like you would use fetch.
Amazing. There needs to be some decent docs for non-React use of App Bridge. Shopify are so behind on their support materials – thank you for this!
