This time I will bring you CDN to speed up the react webpack packaging file process. What are the precautions for CDN to speed up the react webpack packaging file process? Here is a practical case, let’s take a look.

This article does not introduce the basic configuration of webpack. If you have any questions about the basic configuration, please refer to the official documentation.

1. Configure webpack.config.js

Change output.publicPath to the cdn address uploaded to, for example (corresponding to the upload configuration above):

publicPath: "https://your_base_cdn_url" + process.env.NODE_ENV + "/cdn/"

Copy after login

Packing

NODE_ENV=production node_modules/webpack/bin/webpack.js -p

Copy after login

The files packaged in this way include

index.html
12345678.src.js
12345678.src.css
...

Copy after login

At this time, the cdn file has been introduced into the index.html file generated after packaging.

<html lang="en">
<head>
 <title>title</title>
 <link href="https://your_base_cdn_url/production/cdn/12345678.src.css" rel="external nofollow" rel="stylesheet">
</head>
<body id="body">
 <p id="root"></p>
<script src="https://your_base_cdn_url/production/cdn/12345678.src.js"></script></body>
</html>

Copy after login

2. Upload files to CDN

Write a script to upload cdn in the deployment script, for example:

echo "start uploading to upyun"
HOST=v0.ftp.upyun.com
USER=uploader/your-username
PASS=your-password
cd build
files=$(ls | grep -v 'index.html' | xargs)
ftp -inv $HOST <<EOF
user $USER $PASS
mkdir /$node_env/cdn
cd /$node_env/cdn
mput $files
bye
EOF
cd ..
echo "finish uploading to upyun"

Copy after login

Upload the homepage file to the server and use nginx proxy

server {
 listen 80;
 server_name your_server_name;
 access_log /var/log/nginx/your_project.log;
 root /var/www/your_project/production/current;
 location / {
 try_files $uri /index.html =404;
 add_header Pragma no-cache;
 expires -5y;
 }
 location ~ \.(js|css)$ {
 expires 360000;
 add_header Cache-Control "max-age=360000;";
 }
}

Copy after login
