Rails API Authentication with the auth generator

"The Single-Page Application madness is a part of the past and Hotwire is the go-to alternative for interactive Rails applications."

"However, there are some use cases where building an API-only Rails app makes sense: mobile apps, teams that are comfortable with FE frameworks or multi-platform applications."

"In this article we will learn how to add user authentication with the Rails 8 auth generator in API-only apps."

Single-Page Application popularity has declined and Hotwire has emerged as the preferred approach for interactive Rails applications. Building API-only Rails applications remains appropriate for specific scenarios such as mobile apps, teams experienced with front-end frameworks, and multi-platform projects requiring a shared backend.

The auth generator streamlines creation of authentication endpoints and integrates with client applications for secure token-based or session-based authentication, facilitating secure client-server communication across diverse platforms and frontend implementations.
