In the Application URIs section you can add the callback URL you want to use, I configured it to be localhost:3000/callback for testing, you can use any pathname. To get the values of these variables go to Auth0, create an application configured to be regular web app, in the Basic Information section you will have the client id, secret and domain. Note you will only need this for the Remix Dev Server, other adapters like Vercel may add them automatically. This will load them when the app starts only on the server. env file and in your rver file add the following code: import dotenv from "dotenv" server prefix so the file will never be shipped to the client, this will allow us to use environment variables and basically anything we want that doens't run on the browser.

Let's see a way to build a non SPA login using Auth0 and without using Express, so we can use the Remix Dev Server or any other adapter that is not the Express one like Vercel or Fly.io.įirst, let's create a file in our application, I added it on app/services/.

You can use anything that can be serialized to a JSON dictionary as a payload. This is the information that you want stored in the token.

'_jJKavmWrM6d_io5M5PBiK9AKMf_OcK4xpc17kvwI' > token = jwt.encode(, secret_key, algorithm='HS256') > secret_key = "a random, long, sequence of characters that only the server knows" After you verify that the user has provided the correct username and password, you can generate a token for the user: > import jwt Now let's say you want to create a token that gives a user with id 123 access to your application.
