Nodemon e criando o Servidor com express

To create a server with Express and nodemon, you can follow the steps below:

  1. First, make sure you have Node.js installed on your machine. If not, you can download and install it from the official Node.js website.

  2. Once Node.js is installed, open your command prompt or terminal and navigate to the directory where you want to create your Express server.

  3. In the command prompt or terminal, run the following command to create a new Node.js project:

npm init -y

This will initialize a new Node.js project with a default package.json file.

  1. Next, install Express and nodemon as dependencies for your project by running the following command:

npm install express nodemon

This will install Express and nodemon in your project's node_modules folder and update the package.json file with the dependencies.

  1. Create a new JavaScript file (e.g., server.js) in your project directory, and open it in a code editor.

  2. In the server.js file, require the Express module and create an instance of it by adding the following code:

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

This will import the Express module and create a new Express application.

  1. Define the routes and middleware for your server. For example, you can add a simple route that responds with "Hello, World!" by adding the following code:

javascript app.get('/', (req, res) => { res.send('Hello, World!'); });

This creates a route for the root URL ("/") that sends the response "Hello, World!" when accessed.

  1. Finally, start the server by adding the following code at the end of the server.js file:

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

This will start the server and listen on the specified port (in this case, port 3000). The console.log statement will print a message in the console indicating that the server is running.

  1. Save the server.js file, and in the command prompt or terminal, run the following command to start the server using nodemon:

nodemon server.js

Nodemon will monitor any changes in your code and automatically restart the server whenever you save the file.

  1. You can now access your Express server by opening a web browser and navigating to http://localhost:3000 (or the specified port you used).
