Proper way for user authentication with angularjs and flask
I have written several tutorials on RESTful APIs with Flask, all with examples that are ready to use:
http://blog.miguelgrinberg.com/category/REST
The tutorials are:
Designing a RESTful API with Python and Flask
This is a simple RESTful API written in Flask, with authentication.
Writing a Javascript REST client
In this one I implement a Javascript client for the API built in the first tutorial. Here you can see how the client authenticates. I used Knockout instead of Angular for the client, but the principles are the same.
Designing a RESTful API using Flask-RESTful
This one is another way to write the server, using the Flask-RESTful extension to simplify some tasks.
RESTful Authentication with Flask
This is a tutorial specifically dedicated to authentication.
I hope they are useful.
You can use flask-security together with Angular. You can even get CSRF support. I simply disabled WTFForms support and used the Flask backend only as REST API.I wrote a tutorial how to do this here. Source code is also available.
