优化 GitLab 自动部署中 Steer-React-Scripts 打包速度的实现流程和代码如下:
1. 使用代码分割和懒加载技术,将代码分割成多个小模块,只在需要时加载,减少打包时间。
```javascript
// webpack.config.js
module.exports = {
//...
optimization: {
splitChunks: {
cacheGroups: {
commons: {
test: /[\\/]node_modules[\\/]/,
name: "vendors",
chunks: "all"
}
}
}
}
};
```
2. 配置 webpack 的缓存机制,避免重复打包。
```javascript
// webpack.config.js
module.exports = {
//...
output: {
filename: "[name].[contenthash].js",
path: path.resolve(__dirname, "dist")
},
optimization: {
runtimeChunk: "single",
moduleIds: "hashed",
splitChunks: {
cacheGroups: {
vendor: {
test: /[\\/]node_modules[\\/]/,
name: "vendors",
chunks: "all"
},
common: {
name: "common",
minChunks: 2,
chunks: "all",
priority: -10,
reuseExistingChunk: true
}
}
}
},
plugins: [
new CleanWebpackPlugin(),
new HtmlWebpackPlugin({
template: "./public/index.html"
}),
new webpack.HashedModuleIdsPlugin()
]
};
```
3. 使用 Tree Shaking 技术,删除未使用的代码,减少打包体积。
```javascript
// webpack.config.js
module.exports = {
//...
optimization: {
usedExports: true
}
};
```
4. 使用 Gzip 压缩文件,减少文件的大小,提高加载速度。
```javascript
// .gitlab-ci.yml
production:
stage: production
script:
- npm install
- npm run build
- npm install -g gzip-cli
- gzip -9 -r ./build/
artifacts:
name: "build-$CI_COMMIT_REF_NAME-$CI_COMMIT_SHORT_SHA"
paths:
- ./build
```
5. 将静态文件放在 CDN 上,减轻服务器负担,提高访问速度。
```javascript
// index.html
<!-- index.html -->
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<title>React App</title>
<link rel="stylesheet" href="https://cdn.example.com/css/antd.min.css" />
<link rel="stylesheet" href="https://cdn.example.com/css/app.min.css" />
</head>
<body>
<div id="root"></div>
<script src="https://cdn.example.com/js/vendors~main.js"></script>
<script src="https://cdn.example.com/js/main.js"></script>
</body>
</html>
```
6. 安装并配置 babel-plugin-transform-react-constant-elements 插件,将 React 组件转化为常量,减少组件的渲染时间。
```javascript
// .babelrc
{
"plugins": [
"transform-react-constant-elements"
]
}
```
7. 使用 webpack-bundle-analyzer 对打包后的文件进行分析,找出打包过程中的瓶颈,进行优化。
```javascript
// webpack.config.js
const BundleAnalyzerPlugin = require("webpack-bundle-analyzer")
.BundleAnalyzerPlugin;
module.exports = {
//...
plugins: [
//...
new BundleAnalyzerPlugin()
]
};
```
8. 使用 GitLab CI/CD 的缓存机制,避免重复下载依赖和打包。
```yaml
# .gitlab-ci.yml
cache:
key: "$CI_COMMIT_REF_NAME"
paths:
- node_modules/
- package-lock.json
stages:
- build
build:
image: node:14
stage: build
script:
- npm ci --silent
- npm run build
artifacts:
name: "build-$CI_COMMIT_REF_NAME-$CI_COMMIT_SHORT_SHA"
paths:
- build/
```
