Auth0 (Lock) integration in React native + backend - reactjs

I'm trying to find the best way to integrate Auth0 login into a React Native application. The login widget for React Native works perfectly fine, but I'm kind of confused as to how we get the users also logged in on the backend so they can make requests to modify data. The backend is running on Node (Meteor). Do I have to send the id_token to the backend, and login with auth0 there? I'm kind of confused on how to integrate this for both the app and the backend, so that when the user logs into the mobile application, the backend also knows they're logged in.

Whenever the client communicates with the backend, it should send the id_token with the request. On each request, the backend should validate the token (using a jwt library) to verify that the token has a valid signature and has not expired. Once validated, the backend will be able to use the user id embedded within the token to perform any authorization rules or business logic it wishes.
Check out this github project for an example Meteor auth0 backend.

Django OAuth Authentication

I built an app (Django backend, React frontend) that whenever a client login it will generate JWT authentication. React will store the access token and client can use it to access Django backend database.
Then I want to add in social login feature (Google) so I will get back access token from that as well. However, this access token is different from the JWT access token generated before, so I wonder how can I integrate both ways of logging in a user smoothly on both Django and React?
For JWT I use djangorestframework-simplejwt
For social login I use django-allauth
I can run each individual way perfectly on React, but I don't know how to keep both the installations of JWT and allauth in Django settings.

What Should be the basic flow of AWS API Gateway Integration in React JS with cognito user pool authentication system?

I am using React JS in frontend and AWS Server less architecture as the backend of the react application.
So, for the user authentication and authorization I am using the AWS Cognito Service. and for making the requests I am using the axios.
Now, I want to integrate APIs which are created with the AWS API Gateway with cognito user pool. I am able to sign in to the user session and retrieving the id Token, access Token, and Refresh Token. and I am sending the ID Token in the all request which are created with AWS API Gateway. But How can I know that token is expired? because when token is expired it is sending the Network error instead of message("Token is Expired.").
In short I want to handle situation if token is expired or token is invalid. what I have to do?
Give the basic flow of handling the all requests(GET, POST, etc...) using axios.

Silhouette - react + scala + play app authentication flow

I need to create basic app with a silhouette. What I need to do is:
login with Google
Generate JWT
Use JWT to communicate with backend
I don't really know how this flow should look like. My idea is:
use login with Google in react app
generate Google token
use this token to generate JWT in the backend (using silhouette)
retrieve JWT in frontend
Will that flow work? Is there any simpler/better way to do that?
I had similar problem, so that's my proposal:
Create a controller for social authentication on backend side.
In react app add button for authentication and simply redirect to the
backend endpoint.
Authenticate user on backend, use Silhouette JWTAuthenticator to create a JWT token
Redirect to the react app with JWT token in query params.
Save token and use it in consequtive requests

Authentication and Authorization in React app

In a .NET app I can add authentication and authorization using web.config and/or IIS. I can also use [Authorize (Roles = "RoleABC")] in a MVC app's controller or action. And even extend the AuthorizationAttribute
I'm looking into creating a React app for intranet use, and reading these tutorials (ReactJS and MS), but can't find authentication/authorization details.
Even though the app will be Single Page App, I still would like to authenticate and authorize users for certain options within the app, just like I can do in MVC app.
Is the only option to do that way is creating Blazor app instead?
For authentication and authorization, you should use auth tokens (like JWT). Your backend should create an auth token when a client logs in to the system and sends it to the client. Your server also should send the authenticated user information to the client (react app) so that you can render correct pages according to the user type. For example, you can render the admin page for an admin type of user, and the guest page for a guest type of user. You can save this user data as JSON in Redux. Hence you can access the user data from any component of your react. Also, in your backend, you must restrict the endpoints according to the auth token which is sent by the client. In the backend of my app, I follow the below steps:
Authentication check -> Authorization check -> controller (endpoint) -> result
React isn't opinionated on this, so it's up to you to design the implementation. A basic way to do this is:
Log in and obtain an authorized JWT token from the backend and include the account ID when you sign it
Store the JWT token in localStorage, store the account info in Redux
Conditionally limit routes based on account info (ie. admin group) on the front end
Have every auth-required API call include the JWT token in the x-auth-token header, then on the backend use middleware to check if it's still valid. You can then also decode the account ID in order to check its privileges so that you can limit API access

Not sure whether you still need this - I personally feel we should have something bridging the authZ gap between server and client to make it easy. So I spent a few days on a github project for this purpose, here it is: authzyin.
What I tried to do is to leverage policy based authorization from asp.net core - which I think it's very cool - and automatically bring the same definition to the client to use in React via hooks.
For authentication I am using msal.js against AAD - so authN is done on the client and jwt bearer token auth is used for all requests.
It has a client lib and a server lib which can be used together or separately. Of course it might still be lacking some features - please feel free to take it as a reference (contribution is also welcome).

Getting information of user from oauth2 app having the session token

I'm having I think, a misunderstanding of concepts related with Oauth2 protocol. Right now I have 3 applications:
Frontend developed in React
OAuth2 server developed in Golang (not finished)
Another backend app, let's call it: Bussiness Logic app
At first, the user from react can login in the system using the OAuth2 server, the OAuth2 server sends the token and everything's perfect.
Now, when from the the react app some request is send to the Bussiness Logic App the token is also send in the headers. My question is: having the token, should I be able from the Bussiness Logic App to get information fo the user making a request to the OAuth server? is it allowed in the OAuth protocol?
The thing is that I need to know in the Bussiness Logic App which user is logged in, if it's not allowed, how should I fix it?
No.
OAuth 2.0 NOT an Authentication protocol.
If you need Identity Information you need to use OpenID Connect (which is built on OAuth 2.0)
With OpenID Connect you are provided both an Access Token and an Identity Token. The Identity Token will contain "basic" profile information about the "user". The Access Token may be used to obtain more detailed information about the user from the userinfo_endpoint.
