This is a simple web application with REST API.

For those are wondering why we need to open browser like this, it is because of something called CORS. Because of that I wasted a week. But learnt alot during that time. So, what it is? Cross-Origin Resource Sharing is the part of HTTP header which allows you to request resource from other domain or other origin. Here, our domain is Book-Directory/index.html but our server has origin of files. The origin between server and the website differs. Now,error will occur when you try to request and browser will not allow you to access resources from different origin for security purpose. That's why we told the browser to allow access from files in command line. But there is alot to learn. I encourage you to research about it.

It consist of four APIs.

1. GET
2. POST
3. PUT
4. DELETE

GET - With this API we request the resources from server.

POST - With this, we post our data to server.

PUT - It can be used as alternative for POST, but here we use it to update or modify existing content in server.

DELETE - With this, we delete a specific resource in server.

I only tested it in Chromium in my Linux machine.
