How to handle static with nodejs

Website resources

In today’s Internet era, websites have become an important channel for many companies to showcase themselves. With the development of Internet technology, more and more companies have begun to make their websites into dynamic websites. However, in some scenarios, static websites still have their unique advantages, one of which is fast speed. So how to use Node.js to process static resources on a static website? Next, we will discuss this issue in detail.

1. What is a static website?

Static websites are websites composed of static files such as HTML, CSS, and JavaScript. These static files are directly parsed by the browser on the client. Compared with dynamic websites, static websites do not require operations such as databases and server-side parsing of dynamic content, so they are fast and highly secure. However, dynamic websites are more flexible and can provide users with more advanced interactive features.

2. Application of Node.js in static websites

Node.js is a JavaScript environment running on the server side. It has excellent asynchronous IO operation capabilities and an efficient event-driven mechanism. . It is these features that provide Node.js with many advantages in development, such as building high-concurrency, distributed web applications, developing chat rooms and real-time web applications.

In static websites, we can use Node.js to process static resources to optimize the efficiency and performance of the website. Here are some common ways to handle static resources:

1. Using the http-server module

Http-server is a simple, zero-configuration command-line HTTP server. It can quickly start an HTTP server, and supports HTML5 history API (making URLs more beautiful) and cache-free file transfer.

Install http-server module:

npm install -g http-server

Run the following command in the terminal to quickly start http-server:

http-server

Of course, you can also start it on the specified port number http-server:

http-server -p 8080

When using http-server to process static resources, you only need to place the static files that need to be displayed in a specific path. For example, in the current directory where http-server is started, we create a index.html file, we can directly view this file by accessing http://localhost:8080/index.html.

2. Use node-static module

node-static is a simple, fast, easy-to-use static resource server. It supports gzip compression, can customize response headers, and can cache resources, etc. The use of node-static is very simple. You only need to call the static resource server under a specific path.

Install the node-static module:

npm install -g node-static

Execute the following command in the terminal to start node-static:

static

You can customize the port number and file path:

static -p 8080 ./public

When using node-static to process static resources, you only need to place the static files that need to be displayed in the specified directory. For example, in the current directory, we create a public path and add an index.html file to it. , we can view this file directly by visiting http://localhost:8080/index.html.

3. Using the Express framework

Express is a web application development framework based on the Node.js platform. It has rich HTTP rapid development functions and Node.js native HTTP Modules are more efficient and concise.

When using the Express framework to process static resources, we can use its built-in static middleware to quickly process static resources. The specific operations are as follows:

First, you need to introduce the Express module into the application and process the middleware for static resources at the same time.

var express = require('express');
var app = express();

// 使用中间件处理静态资源
app.use(express.static('public'));

The above code indicates that Express will look for static resources in the public folder. For example, if we have an index.html file in the public folder, we can directly view this file by accessing http://localhost:8080/index.html.

4. Using the Koa framework

Koa is a new web framework that provides a set of elegant methods to make the server-side code of the website more concise and more reliable. It is more readable and provides a fast and efficient way to build network applications.

When using the Koa framework to process static resources, we can use the koa-static module. koa-static is a static resource server for the Koa framework. It has features such as gzip compression, ETag support, and cache support.

Using the koa-static module to process static resources is similar to using node-static. You only need to create a complete file path in the specified directory and then start the Koa service.

First, you need to introduce the koa module and koa-static module into the application:

var Koa = require('koa');
var serve = require('koa-static');
var app = new Koa();

Secondly, you need to use the koa-static module to process static resources:

app.use(serve(__dirname + '/public'));

The above code Indicates using Koa to process static resources in the public folder. For example, if we have an index.html file in the public folder, we can directly view this file by accessing http://localhost:8080/index.html.

Summary:

The above introduces four ways to process static resources. Different methods are suitable for different scenarios. Developers can choose the appropriate method according to actual needs.

No matter which method is used, they are specially optimized for the processing of static resources, making the reading and response of static resources quite efficient, thus improving the performance and stability of the entire application.
