With the continuous development of web technology, more and more people are paying attention to how to build a local web server to facilitate their development and testing work. As a very popular server-side development framework, Node.js can also be used to build web local servers.

This article will introduce how to use Node.js to build a simple web local server, and how to run and manage the server.

  1. Install Node.js

Before you begin, you need to install Node.js. If you have not installed it yet, please go to the Node.js official website (https://nodejs.org) to download the latest version and follow the prompts to install it.

  1. Create Project Folder

Before continuing, you need to create a project folder for your local server. Here we create a folder named "myserver" to store project files and code.

  1. Create server file

Create a file named "server.js" under the project folder to store the server code. In this code file, we need to use the built-in HTTP module of Node.js to create an HTTP server object and listen to user requests.

Here is a simple sample code:

var http = require('http');
var server = http.createServer(function (req, res) {
    res.writeHead(200, { 'Content-Type': 'text/plain' });
    res.end('Hello, World!');
});
server.listen(8080);
Copy after login

This code will create an HTTP server and return an HTTP response containing the text "Hello, World!" when a user request is received. The server will listen on port 8080, you can change the port number if needed.

  1. Run the local server

Switch to the project folder "myserver" on the command line and run the following command to start the local server:

node server.js
Copy after login

This The command will start the Node.js server and bind it to port 8080. You can view the server's response by visiting "http://localhost:8080" in your browser.

  1. Manage local server

Once your local server is running, you can stop the server using the following command:

ctrl + c
Copy after login

This command will terminate from the console The currently running program. If you want to let the local server run in the background, please use the following command:

nohup node server.js &
Copy after login

This command will put the server process into the background and write the output information to the nohup.out file. If you want to stop the backend server, use the following command:

killall node
Copy after login

This command will stop all processes named "node".

  1. Summary

This article introduces how to use Node.js to build a simple web local server. By using Node.js and the HTTP module, we can easily create a local server for developing and testing web applications. Of course, Node.js also has more functions and extension libraries that can help you better develop and manage your web applications. I hope this article will be helpful to you.
