How to configure and use CDN for acceleration in Vue

In the Vue project, using CDN (Content Delivery Network) can effectively accelerate web page loading speed and improve user experience . CDN technology distributes static resource files to servers in various locations around the world, allowing users to quickly obtain resources from the server closest to the user, reducing data transmission time and delays.

The following will introduce in detail how to configure and use CDN for acceleration in Vue.

First, we need to find a reliable CDN service provider and register an account. There are currently many well-known CDN service providers on the market, such as Qiniu Cloud, Alibaba Cloud, Tencent Cloud, etc. Choose a supplier that suits your project needs and financial strength.

1. Register and create a CDN service

Register and log in to the CDN service provider's website, create a new project, and configure a domain name for the project. The relevant provider will provide you with a CDN access address (a CNAME record needs to be configured) and an accelerated resource access address.

2. Configure Vue project

Open the root directory of the Vue project and find the following code in the public/index.html file:

<link rel="icon" href="<%= BASE_URL %>favicon.ico">

Replace it For:

<link rel="icon" href="CDN訪問地址/favicon.ico">

In this way, the icon file of the website will be accelerated and loaded through CDN.

Similarly, find the following code in the public/index.html file:

<script src="<%= BASE_URL %>js/app.js"></script>

Replace it with:

<script src="CDN訪問地址/js/app.js"></script>

In this way, the main entry file app of the Vue project. js will also be loaded via CDN.

3. Packaging the Vue project

In the root directory of the Vue project, run the following command to package the project as a static resource file for the production environment:

npm run build

After packaging is completed, a dist folder will be generated in the root directory, which contains the packaged static resource files.

4. Upload static resource files

Upload all files in the dist folder to the CDN service provider's console and publish these files. After successful publishing, the CDN service provider will generate a URL address for accelerated access for these files.

5. Configure resource access path

Find the vue.config.js file in the root directory of the Vue project (if not, you need to create one manually), in the file Add the following code:

module.exports = {
  publicPath: 'CDN加速訪問URL'
}

Replace 'CDN accelerated access URL' with the URL address of CDN accelerated access.

At this point, the CDN configuration and use of the Vue project is completed.

Since CDN resources will be cached on node servers around the world, when a user accesses the website, the resources will be loaded from the node server closest to the user, which greatly reduces the resource request time and improves web page loading. speed.

It should be reminded that before configuring CDN, we need to optimize the performance of the project first, including reducing HTTP requests, compressing and merging static resource files, using browser cache, etc.

In short, using CDN for acceleration can improve the performance and user experience of the Vue project and provide users with better access speeds. Hope the above content is helpful to you.
