Authentication Service

Understand how to build client-side authentication services using React by creating isolated service files for handling headers, sign-up, login, logout, and user profile management. Learn to store and manage user tokens securely in localStorage and integrate with backend APIs using axios.

We'll cover the following...

Many approaches can be used to integrate the API into the frontend, but the ones that we chose will depend on the scale of our project. For our purposes, it’s better to isolate the API integration and transfer it to the application components using abstract services.

Services

The services approach scales exceptionally well with different applications and makes those same applications easier to maintain and debug. In the existing services directory, we’ll create these three files:

  • The services/auth.header.js file handles the common header that must be presented in all HTTP requests.
