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)

/pictures

Create new picture

List pictures

N/A (update all)

N/A (destroy all)

/pictures/1

Error

Show picture ID 1

Update picture ID 1

Destroy picture ID 1

  • The format is JSON
  • Bulk updates and bulk destroys are not safe, so we will not implement those
  • POST, GET, PUT, DELETE equals to CREATE, READ, UPDATE, DELETE, with the abbreviation CRUD

Using Express

Building a REST API is pretty popular in the Node.js community. There are a lot of different ways to handle such a task. There are even ready-to-use modules such as rest.js or restify. However, we will use another framework called Express.

Tip

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