Create Authentication Logic

We've got an very small existing application based on the following setup: Application with front-end based on Angular 5 consuming a RESTful API based on PHP framework Laravel 5.6 For authentication we look into using the Laravel Passport Oauth2 component. What you need us to provide is the following: Enable our Angular front-end app to: - Check if authenticated, if not show login form - Login by user email and password - Login and store the access and refresh token safely - Set an option for remembering the user - Logout and delete the tokens - Add the access token to every server request based on an interceptor - Autorefresh access token before it expires
