Developing a REST API
Let's plan our first REST API. With Express, it is very easy and the development itself does not really differ from website development.
Here is a summary of what we want to implement as a REST API:
|
Resource (URI) |
POST (create) |
GET (read) |
PUT (update) |
DELETE (destroy) |
|---|---|---|---|---|

|
Create new picture |
List pictures |
N/A (update all) |
N/A (destroy all) |
|
|
Error |
Show picture ID 1 |
Update picture ID 1 |
Destroy picture ID 1 |
The format is JSON

POST, GET, PUT, DELETE equals to CREATE, READ, UPDATE, DELETE, with the abbreviation CRUD

Express is a web application framework for Node.js. With Express, we can build websites as well as web...
