You can use the JSON Web Token standard as a part of your authentication and authorisation solution in a project built with Spring Boot and Angular. Check out this post to learn how to apply Spring Security, AuthGuard and JWT to your apps.
An Angular app is served by a different host than a Spring Boot API, so reaching for data via REST API will result in the following error: “Failed to load http://localhost:8080/api: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘http://localhost:4200’ is therefore not allowed access.” Read this post to learn how to configure Cross-origin resource sharing (CORS) to enable the cross-domain communication on a development environment.
