Netlify is a platform for hosting frontend web applications. It also supports a bunch of server-side features like identity, lambda functions, form submissions, or custom microservices. In this post, I show an example of using the identity service in an Angular application to authenticate users. This post assumes the reader is familiar with the structure of an Angular application including routing, components, and services but you don't need to be an expert. It also requires npm and the Angular cli to run locally.
