nodejs multi-site deployment

With the development of the Internet, more and more companies and individuals are beginning to build their own websites or applications. In actual deployment, due to the increase in visits, a single server can no longer meet the demand, so multi-site deployment has become an inevitable trend. This article explains how to use Node.js for multi-site deployment.

1. The concept of multi-site deployment

Multi-site deployment is to deploy multiple websites or applications on the same server and access them through different domain names or ports. This can avoid resource waste and improve server utilization.

2. Node.js implementation of multi-site deployment

Node.js, as an event-driven asynchronous I/O framework, can easily implement multi-site deployment . Two implementation methods are introduced below.

2.1 Multi-site deployment based on domain name and port

Multi-site deployment based on domain name and port is the most common method. In Node.js, this can be achieved using the http module and express framework.

First, you need to install Node.js and express framework on the server. You can then follow these steps:

1. Create an index.js file in the root directory of your application.
2. Introduce http and express modules into the index.js file and create an express application.

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

3. Define different routing and processing functions in the application.

app.get('/', function(req, res){
  res.send('Welcome to my website!');
});

app.get('/about', function(req, res){
  res.send('About me');
});

4. Subsequently, the application needs to be bound to different ports and domain names.

http.createServer(app).listen(80, 'example.com');
http.createServer(app).listen(8080, 'example.org');

5. Finally, run the index.js file.

node index.js

Follow the above steps, you can easily implement multi-site deployment based on domain names and ports.

2.2 Multi-site deployment based on subdomain names

Multi-site deployment based on subdomain names is to use different subdomain names under the same main domain name to achieve multi-site deployment. This approach can improve the user's access speed and experience, and can also better maintain the application.

In Node.js, you can use the express-subdomain module to implement multi-site deployment based on subdomain names. The following describes the specific implementation steps:

1. Create an index.js file in the root directory of the application.
2. Introduce http, express and express-subdomain modules into the index.js file, and create an express application and subdomain route.

const http = require('http');
const express = require('express');
const subdomain = require('express-subdomain');
const app = express();

const sub1 = express();
const sub2 = express();

3. Define different subdomain routing and processing functions in the application.

sub1.get('/', function(req, res){
  res.send('Welcome to subdomain1!');
});

sub2.get('/', function(req, res){
  res.send('Welcome to subdomain2!');
});

4. Bind subdomain routing to the main application.

app.use(subdomain('sub1', sub1));
app.use(subdomain('sub2', sub2));

5. Finally, run the index.js file.

node index.js

Follow the above steps, you can easily implement multi-site deployment based on subdomain names.

3. Summary

Through the above introduction, we can see that Node.js implements multi-site deployment in a relatively simple way, which is mainly divided into multi-site deployment based on domain names and ports. and subdomain-based multi-site deployment. During the implementation process, it is necessary to reasonably arrange the routing and processing functions of the application, and bind different applications to different ports, domain names, and subdomain names.

The multi-site deployment of Node.js can easily implement the deployment and maintenance of websites and applications. It can also improve server utilization and provide better conditions for the development of enterprises and individuals.
