Glee-O-Meter

Glee-o-meter is a simple Angular 7 application focused on the interaction with a Spring REST server.

The data-centric application offers a basic user-management section, with the possibility to sign-in new users. Each user can manage a list of glee-levels, each one associated to a date, time and a comment. There are three different roles:

• Admin: has full permissions on the whole data
• User manager: has permissions on user data
• User: has full permissions on owned glee data.

The application has the following features:

• data access with pagination, sorting, ordering and filtering;
• CRUD operations on whole data;
• sign-in to permit the registration of new users;
• authentication based on oauth2 JWT, with token refresh;
• consumes REST resources /api/glee, /api/users and /api/signin

The server side is implemented with Spring boot, slightly customized to run on Google App Engine. Server implementation features the following:

• oauth2 JWT authentication with spring-boot, using grant types password and refresh token;
• publish 2 authenticated REST resources /api/glee, /api/users and one public /api/signin for user registration;
• method-level authorization based on @PreAuthorize and @PostAuthorize;
• data access based on logged user's permissions;
• Spring based JSR-349 data validation;
• CORS configuration for running separated local server and client development environments;

A running version is deployed on Google App-Engine cloud.
