Learn How To Create A Restful Api Using Node.js Express Jwt And Sequelize(part1)

In this tutorial, we will learn how to create a RESTful API using Node.js, Express, JWT, and Sequelize. This tutorial will be divided into multiple parts, so make sure to follow along with each part to fully understand how to build a complete RESTful API.

Setting Up the Project

The first step is to set up our project. Create a new directory for your project and open it in your code editor.

“`html

mkdir restful-api
cd restful-api

“`

After creating the project directory, we need to initialize a new Node.js project. This can be done by running the following command in the terminal.

“`html

npm init -y

“`

Now, we need to install the necessary dependencies for our project. We will be using Express for creating our RESTful API, JWT for authentication, and Sequelize for interacting with our database. Run the following command to install these dependencies.

“`html

npm install express jsonwebtoken sequelize sequelize-cli mysql2

“`

Creating the Express Server

Now that we have all the necessary dependencies installed, let’s create our Express server. Create a new file called `server.js` and add the following code to it. This code sets up a basic Express server with a route that returns a simple message.

“`html

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

app.get('/', (req, res) => {
  res.send('Welcome to our RESTful API');
});

const port = process.env.PORT || 3000;
app.listen(port, () => {
  console.log(`Server is running on port ${port}`);
});

“`

Now, run the following command in the terminal to start the Express server.

“`html

node server.js

“`

After running the above command, you should see a message in the terminal saying “Server is running on port 3000”. This means that our Express server is up and running.

That’s it for part 1 of this tutorial! In the next part, we will learn how to set up JWT authentication and create endpoints for our RESTful API. Stay tuned for more!
