This article mainly introduces "how to build Node.js programming environment on linux". In daily operation, I believe many people have doubts about how to build Node.js programming environment on linux. Xiaobian consulted all kinds of information and sorted out simple and easy to use operation methods. I hope to answer the doubts of "how to build Node.js programming environment on linux"! Next, please follow the small series to learn together!

Step 1: Install Node.js

1. Execute the following command to download the installation package for Node.js.

wget https://npm.taobao.org/mirrors/node/v12.4.0/node-v12.4.0-linux-x64.tar.xz

2. Execute the following command to extract the Node.js installation package:

tar -xvf node-v12.4.0-linux-x64.tar.xz

3. Rename the Node.js installation directory by executing the following command:

mv node-v12.4.0-linux-x64/ /usr/local/node Step 2: Configure Node.js

1. Execute the following command to add the executable directory of Node.js to the system environment variables:

echo "export PATH=$PATH:/usr/local/node/bin" >> /etc/profile

2. Execute the following command to make the newly configured Node.js environment variable take effect immediately:

source /etc/profile

3. Execute the following command to view node and npm versions separately.

node -vnpm -v

Step 3: Test the Node.js environment

1. Create a test file using the vim command.

vim HelloWorld.js

2. Write the following code in the HelloWorld.js file.

var http = require('http');http.createServer(function (request, response) { response.writeHead( 200, { 'Content-Type': 'text/plain' }); response.end('Hello World\n');}).listen(8080);console.log('Server started');

3. Run the HelloWorld.js file by executing the following command:

node HelloWorld.js

4. Open a browser and type http://:8080 in the address bar, for example http://127.0.0.0:8080.

If the following interface is returned, it means success.

At this point, the study of "how to build a Node.js programming environment on linux" is over, hoping to solve everyone's doubts. Theory and practice can better match to help you learn, go and try it!
