NodeJS server creation and restart operation code sharing

This time I will share with you the nodeJS server creation and restart operation code. What are the precautions for the nodeJS server creation and restart operation? The following is a practical case, let's take a look.

1: First create a server.js file in the nodejs project, enter the following code

var http = require("http"); 
http.createServer(function(request, response) { 
 response.writeHead(200, {"Content-Type": "text/plain"}); 
 response.write("Hello World"); 
 response.end(); 
}).listen(8888);

and then enter the project path under cmd, Then enter node server.js to start the server, and then enter http://localhost:8888/ in the browser address bar to see the output Hello World on the interface. If we modify the value of Hello World and refresh the browser, we will find the output and There is no change. At this time, you need to manually restart the server to change the output. This is undoubtedly very annoying during the development process. It is best to have a script that can monitor all changed files. Once a file is found to be changed, the service will be restarted immediately. Reload the file you just modified.

Here is a recommendation: nodemon.

First of all, in order to make this command available globally, it is best for us to install it globally:

npm install -g nodemon

Two: ExitThe current terminal command output line command: Ctrl C twice.
