Code Explaination

The entire coding logic is divided into two main part, frontend and backend code. Frontend is developed using Angular 8 and backend using Spring Boot 2 version. These technologies have been chosen because of their ease of development.

Front End Code Explaination

Front end code is developed using components like login, logout, menu, home, footer, todo list and todo. Similarly, angular code is architected into multiple layer with service, constant and component layer. Additionally, routing has been considered with active routing and current authentication. Angular code is packaged using 'ng build' command in root directory and dist files are generated into public folder of backend code' resources folder

Back End Code Explaination

Backend is organised into JwtAuthenticationRestController and TodoController process. Appropriately Model beans, service and repository classes/interfaces have been created. JPARepository interface is used to provide JPA features around the model classes.

H2 with hibernate is configured to store in-memory data. Similarly, exception handling, utility, web security classes have been configured.

Things to consider in future

1. JUnit test cases - considering all testcases for each method.
2. angular test cases - - considering all testcases for each method.
3. e2e test cases - e2e test script
4. Spring Test cases - e2e integration testing
5. Code optimisation - using caching to store todos at client/server side.
