默认集成插件

  • res-cli
  • egg-view-react-ssr
  • egg-view-nunjucks
  • egg-webpack
  • egg-webpack-react

说明:Node 开发遵循 Eggjs 所有已有项目规范, 参考:https://github.com/easy-team/res-awesome

React 服务端渲染

https://easy-team.gitee.io/egg-react/node

  • 在 Node 服务端运行 jsbundle,并渲染成完整的 HTML 内容返回给客户端
  • 使用 ctx.render 进行 React 服务端渲染,文件名为 Webpack entry 文件名,对应文件为 app/view 目录
  • ctx.render 渲染时,默认渲染失败会自动降级为客户端渲染模式
import { Controller, Context } from '@easy-team/res';
export default class AdminController extends Controller {
  public async home(ctx: Context) {
    await ctx.render('admin/home.js', { url: ctx.url.replace(/\/admin/, '') });
  }
}

React 客户端渲染

  • 服务端只渲染 HTML 的 HTML,HEAD,BODY 标签结构,具体 BODY 内容由浏览器进行渲染
  • 使用 ctx.renderClient 进行 Vue 客户端渲染, 文件名为 webpack entry 的文件名,注入的页面 JS 文件为 app/public 文件。
import { Controller, Context } from '@easy-team/res';
export default class AdminController extends Controller {
  public async home(ctx: Context) {
    await ctx.renderClient('admin/home.js', { url: ctx.url.replace(/\/admin/, '') });
  }
}

React + Nunjucks 静态页面前端渲染

Webpack 根据 HTML 模板 直接构建成静态 HTML 页面,然后通过 Nunjucks 执行页面渲染.

  • ${root}/app/controller/render.ts
import { Controller } from 'egg';
export default class ReactController extends Controller {
  public async reactNunjucksRender() {
    const { ctx } = this;
    await ctx.render('react-nunjucks-render.tpl', { 
      title: 'Nunjucks Render',
      data: JSON.stringify({ text: '基于 Egg + React + Nunjucks + TypeScript + Mobx + Webpack Client Side Render' }) 
    });
  }
}
  • config/res.config.js
// https://easy-team.gitee.io/egg-react/config
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const resolve = (filepath) => path.resolve(__dirname, '..', filepath);
module.exports = {
  entry: {
    'react-nunjucks-render': 'app/web/page/react-nunjucks-render/index.tsx',
  },
  plugins: [
    new HtmlWebpackPlugin({
      chunks: ['runtime', 'common', 'react-nunjucks-render'],
      filename: '../app/view/react-nunjucks-render.tpl',
      template: './app/web/view/index.tpl'
    })
  ]
};

React + Nunjucks Asset前端渲染

https://easy-team.gitee.io/egg-react/asset

  • ${root}/app/controller/render.ts
import { Controller, Context } from '@easy-team/res';
export default class AdminController extends Controller {
  public async home(ctx: Context) {
     await ctx.renderAsset('asset.js', { 
      title: 'React Asset Client Render',
      text: 'Egg + React + TypeScript + Webpack Client Side Render' 
    }, { layout: path.join(ctx.app.baseDir, 'app/web/view/layout.tpl'),} );
  }
}
  • ${root}/app/web/view/layout.tpl renderAsset 自动注入资源依赖对象,然后自己根据 asset 对象进行 CSS和 JS 注入到 HTML 页面。
<!DOCTYPE html>
<html lang='en'>
<head>
  <title>{{title}}</title>
  <meta name='keywords'>
  <meta name='description'>
  <meta http-equiv='content-type' content='text/html;charset=utf-8'>
  <meta name='viewport' content='initial-scale=1, maximum-scale=1, user-scalable=no, minimal-ui'>
  <link rel='shortcut icon' href='/favicon.ico' type='image/x-icon' />
  {% for item in asset.css %}
    <link rel="stylesheet" href='{{item}}' />
  {% endfor %}
</head>
<body>
  <div id='app'></div>
  <script type="text/javascript">
    window.__INITIAL_STATE__ = {{ asset.state | safe }};
  </script>
  {% for item in asset.js %}
    <script type="text/javascript" src="{{item}}"></script>
  {% endfor %}
</body>
</html>
