How do I call one Flask view from another one?

Question

I have a JSON API in one blueprint module, and a web frontend in another one.

I would like to shave off a few AJAX requests the client JS code would have to make by embe

You can use a Flask test client for this:

client = app.test_client()
response = client.get('/your/url', headers=list(request.headers))

To keep the authentication with Flask-Login you need to pass your request's headers.
