Building RestFul API Microservice using Express JS Project #05

Express JS is a popular web application framework for Node.js that provides a robust set of features for building RestFul APIs. In this tutorial, we will create a microservice using Express JS to build a RestFul API for a project.

Step 1: Setting Up the Project

First, we need to create a new directory for our project and initialize it with a package.json file. We can do this by running the following commands in our terminal:


mkdir project05
cd project05
npm init -y

Step 2: Installing Express

Next, we need to install Express as a dependency for our project. We can do this by running the following command in our terminal:


npm install express

Step 3: Creating the API

Now that we have Express installed, we can create our RestFul API by creating a new file called server.js in our project directory. We can then define our API endpoints and logic within this file. Here’s an example of how our server.js file might look:


const express = require('express');
const app = express();

app.get('/api/users', (req, res) => {
// Your logic to fetch users from database or any other source
res.json({ users: [] });
});

app.post('/api/users', (req, res) => {
// Your logic to create a new user
res.json({ message: 'User created' });
});

app.listen(3000, () => {
console.log('Server is running on port 3000');
});

Step 4: Running the API

Finally, we can run our API by running the following command in our terminal:


node server.js

Once the server is running, we can test our API endpoints by making requests to http://localhost:3000/api/users using tools like Postman or curl.

And that’s it! We have successfully built a RestFul API microservice using Express JS for our project. This API can now be used to serve data and functionality to other parts of our application or even external clients.
