RESTful API

It's a basic RESTful API in node js with the express, sqlite,, body-parser and async-await. I just want to learn how to create the restful api and how to work it on the GET, POST, PUT, DELETE request as well as it should work on the specific id's of the sqlite3 database table row. Such as adding username, email and phone at id 6. Also create a test file to test all 7 methods and test it if it works Clear instructions will be provided. Very Urgent!
