react-puppeteer v1.1.2
React-Puppeteer
这是一个可以在 tsx 环境中,使用 puppeteer 对 tsx 组件进行截图的库
强大的现代化框架 React.js 将为你管理组件和代码
VScode 安装插件
ES7+ React/Redux/React-Native snippets
环境准备
yarn add react-puppeteer -W
- .puppeteerrc.cjs
自动搜索浏览器内核
/**
* @type {import("puppeteer").Configuration}
*/
module.exports = require('react-puppeteer/.puppeteerrc')
- tsconfig.json
{
"include": ["src/**/*"],
// 继承react-puppeteer的ts配置
"extends": ["react-puppeteer/tsconfig.json"]
}
使用教程
// src/Word.tsx
import React from 'react'
export default () => {
return <div> hello React ! </div>
}
// src/image.tsx
import React from 'react'
import { pictureRender, render, ObtainProps } from 'react-puppeteer'
import Word from './Word.tsx'
export const pictureRender = (uid: number, Props: ObtainProps<typeof Word>) => {
// 生成 html 地址 或 html字符串
return render({
// html/hello/uid.html
join_dir: 'hello',
html_name: `${uid}.html`,
html_body: <Word {...Props} />
})
}
// src/index.ts
import { pictureRender } from './image.tsx'
const img: Buffer | false = await pictureRender(123456, {})
if (img) {
// 可fs保存到本地
}
- run
npx tsx src/index.ts
本地调试
- tsconfig.json
{
"include": ["tsxp.config.tsx"]
}
- tsxp.config.tsx
import React from 'react'
import { defineConfig } from 'react-puppeteer'
const Music = () => {
return <div> 我的音乐</div>
}
export default defineConfig([
{
url: '/music',
options: {
html_body: <Music />
}
}
])
- dev
npx tsxp dev
扩展功能
VScode 安装插件
Path Intellisense
文件引入
createRequire
请确保引入的是项目目录下的文件
import React from 'react'
import { BackgroundImage, createRequire } from 'react-puppeteer'
const require = createRequire(import.meta.url)
export default function Word() {
return (
<>
<BackgroundImage url={require('./resources/example.png')} size="100% 100%">
我有了一个背景图
</BackgroundImage>
<img src={require('./resources/example.svg')} />
<img src={require('./resources/example.png')} />
</>
)
}
截图方块
Puppeteer 截图是默认 body
你可以指定截图的元素为section
也可以设置section
为指定的高度
export default function Word({ data }: PropsType) {
return (
<div className="text-red-500 p-2 text-xl m-80">
Hello, {data.name}!<section className="h-[80rem] w-[90rem]">嘎嘎</section>
</div>
)
}
export const pictureRender = (uid: number, Props: Parameters<typeof Word>[0]) => {
// 生成 html 地址 或 html字符串
return render(
{
// html/hello/uid.html
join_dir: 'hello',
html_name: `${uid}.html`,
html_body: <Word {...Props} />
},
{
tab: 'section'
}
)
}
元素插入
import { createRequire, LinkCSS, LinkESM } from 'react-puppeteer'
const require = createRequire(import.meta.url)
export const Link = () => {
return (
<>
<LinkESM src={require('../../resources/js/hello.js')} />
<LinkCSS src={require('../../resources/css/hello.css')} />
</>
)
}
import { readFileSync } from 'fs'
import { render } from 'react-puppeteer'
import { Link } from './link.tsx'
export const pictureRender = (uid: number, Props: Parameters<typeof Word>[0]) => {
// 生成 html 地址 或 html字符串
return render({
// html/hello/uid.html
join_dir: 'hello',
html_name: `${uid}.html`,
html_head: <Link />,
html_body: <Word {...Props} />
})
}
引用别名
定义一个显示图片的组件
import React from 'react'
export default () => <div className="show-image"></div>
创建一个 css 文件
图片位置./resources/exp.png
.show-image {
// 引入上级目录的图片资源
background-image: url('../exp.png');
}
正常情况下,截图工具是无法识别 css 内部引用的其他资源的
资源的位置随便可能会因为插件位置的改变而改变
框架的设计变更也可能发生改变
生产的 html 文件随时会变化
此时,开发者需要借助别名系统,确保资源能正常被识别出来
import { dirname, join } from 'path'
import { createRequire, render } from 'react-puppeteer'
import ImageComponent from './views/image.tsx'
const require = createRequire(import.meta.url)
export const ScreenshotOptions = {
// 携带了别名的资源 效果等同 <head />
html_files: [require('./resources/css/example.main.css')],
// 设置别名
file_paths: {
// 定位自身的 md文件,并获取目录地址
'@example': dirname(require('./README.md'))
},
// <head />
html_head: <Link />
}
export const pictureRender = (uid: number, Props: Parameters<typeof ImageComponent>[0]) => {
// 生成 html 地址 或 html字符串
return render({
// html/hello/uid.html
join_dir: 'hello',
html_name: `${uid}.html`,
...ScreenshotOptions,
html_body: <ImageComponent {...Props} />
})
}
.show-image {
// 在外部资源中使用别名引用
background-image: url('@example/resources/exp.png');
}
tailwindcss
可以跟 talwindcss 结合,生产 css 后,引入到 head 组件
yarn add tailwind -W
- input.css
@tailwind base;
@tailwind components;
@tailwind utilities;
- tailwind.config.js
import { createRequire } from 'module'
const require = createRequire(import.meta.url)
/**
* @type {import('tailwindcss').Config}
*/
export default {
// 内容
content: ['src/**/*.{jsx.tsx.html}'],
plugins: []
}
- output
npx
本地 -i
输入 -o
输出 -m
压缩
npx tailwindcss -i ./input.css -o ./output.css -m
- link.tsx
import React from 'react'
import { createRequire, LinkCSS } from 'react-puppeteer'
const require = createRequire(import.meta.url)
export const Link = () => <LinkCSS src={require('./output.css')} />
