介绍

express 视图引擎 tsx 的实现 .

安装

npm install express-tsx typescript --save

使用示例

主文件

//创建包含 express-tsx 视图引擎的 express 服务
const { expressTsx,expressTsxMiddleware } = require('../')
const server = expressTsx(__dirname)
//服务监听
server.listen(9000,function(){ console.log(`server is running on ${this.address().port}`) })
//**注意**:在渲染视图前需要根路由注入中间件
server.use(expressTsxMiddleware)
//渲染视图
server.use('/',(req,res)=>res.render('./view.tsx'))

视图文件

import React = require('react')
console.log('express-tsx' as any)
export default ()=>
<div>
  hello world
</div>

示例运行

  • 克隆本项目
    git clone https://github.com/shynome/express-tsx.git
    
  • 安装依赖 ; 进入示例目录 ; 运行
    npm install ; node example
    
  • 在浏览器中打开 示例:http://127.0.0.1:9000/
    一切正常的话会看到 : hello world

实现流程

  • 使用require('express-tsx').middleware中间件用来注入要使用的数据
  • express 中指定要渲染的文件 , app.use('/path',(req,res)=>res.render(file))
  • 使用 typescript 将该文件及其引用的文件进行编译
  • 调用用 res.locals.express_tsx_html 函数 返回用来渲染界面的html文件
  • 通过require('express-tsx').middleware返回编译成es5js文件
  • 浏览器通过 browser.int.ts 渲染界面

深入使用

示例1

替换 res.locals.express_tsx_html 函数来输入你自己的 html 结构来应对 seo 等情况
  • 替换res.locals.express_tsx_html函数, 相关代码片段:
    源文件
    const render2 = expressTsx(__dirname)
    render2.use((req,res,next)=>{
      let originTsxHTML = res.locals.express_tsx_html
      res.locals.express_tsx_html = async(...r)=>{
        return (await originTsxHTML(...r)).replace(`<body>`,`<body>render by diy html function`)
      }
      next()
    })
    render2.use('/',(req,res)=>res.render(renderFile))
