There are several Web services available on the internet. Many web services, like Twilio and Facebook, make their data accessible to third-party applications through an application programming interface (API). One of the most popular ways to build APIs is the REST(REpresentational Stateless Transfer) architecture style.

This post will be a good primer for a Java programmer looking to integrate any web-service APIs.

In this post, I shall show a working source code and a docker container image to get started quickly.

Use below two commands to see the example in action.

make build-container 
make test-container

Purpose

Provide a sample example code for RESTful Web Services in JavaScript.

Installation

Please refer to Makefile and Dockerfile for install and build instructions.

    make install
    make build
    make build-container

Resource

ExpressJS is one of the most popular HTTP server libraries for Node.js

URIs
```
  /event
  /events/:id
```

Restful Methods

POST

 app.post('/event', function (req, res))

GET

 app.get('/', function (req, res))
 app.get('/events/:id', function (req, res))
 app.get('/listUsers', function (req, res))

PATCH

 app.patch('/events/:id', function (req, res))

DELETE

 app.delete('/events/:id', function (req, res))

Testing

Run Server
```
  make build
```
Run Client
```
  make run
  make test-container
```

Next Steps

Follow the below links for the source code and Dockerfile

I hope that these references will make getting started extremely easy.

Enjoy!
