Installation and testing of Mac node js environment

1. Configuration of mac node.js environment

Step 1: Open the terminal and enter the following command to install Homebrew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
 

Homebrew official website http://brew.sh/index_zh-cn.html

Step 2: Install node, enter the following command in the terminal

brew install node
 

Step 3: Check whether the node installation is successful

2. New test program

Step 1: Create a new file test.js

var http = require('http');

var data = {key : 'value', hello: 'world'};

var srv = http.createServer(function (req, res) {
	res.writeHead(200, {'Content-Type': 'application/json'});
	res.end(JSON.stringify(data));
});

srv.listen(8080, function() {
	console.log('listening on localhost:8080');
});
 

Step 2: Use the terminal to find the file directory where it is located and run

 node Desktop/test.js listen on localhost:8080
 

Step 3: Visit through the browser and return the data in json format

Step 4: The front end can analyze data through this interface.
