本文将讲述如何基于webpack与TypeScript搭建一个基础的支持less模块的solidjs项目。方便后续涉及到solidjs相关分析与讨论都可以基于本文的成果之上进行。
前置
- nodejs v14
- 全局yarn(npm亦可)
- 稳定的网络环境
创建根目录solidjs-webpack-ts-example
:
mkdir solidjs-webpack-ts-example
cd solidjs-webpack-ts-example

git初始化
代码语言:javascript复制# 前置:添加.gitignore文件
git init
git add .
git commit -m "init"
库安装
webpack 4件套
代码语言:javascript复制yarn add -D webpack webpack-cli webpack-dev-server html-webpack-plugin
样式处理 4件套
代码语言:javascript复制yarn add -D less less-loader css-loader mini-css-extract-plugin
- less:less核心编译解析库;
- less-loader:webpack与less的桥梁。当webpack处理less时,通过配置指定交给less-loader,less-loader调用安装的less,将less代码编译为css代码;
- css-loader:wepback处理css样式代码的loader。处理css,或处理来自less编译成的css;
- mini-css-extract-plugin:css样式处理最后一个环节,交给该插件的提供的loader、plugin完成独立样式文件打包生成。
babel 7件套
代码语言:javascript复制yarn add -D @babel/core
yarn add -D @babel/preset-env @babel/preset-typescript babel-preset-solid
yarn add -D @babel/plugin-proposal-class-properties @babel/plugin-proposal-object-rest-spread
yarn add -D babel-loader
- @babel/core:babel核心库;
- @babel/preset-env、@babel/preset-typescript、babel-preset-solid(这个preset名字目前没有符合babel规范):babel扩展preset,整合当前主流浏览器支持语法、typescript语法支持以及solidjs相关语法支持;
- @babel/plugin-proposal-class-properties、@babel/plugin-proposal-object-rest-spread:babel扩展插件,支持类定义属性以及
...
剩余属性解构语法; - babel-loader:webpack与babel的桥梁。当webpack处理相关代码的时候,通过配置指定交给babel-loader,babel-loader内部调用上述第1个babel核心库,并结合相关的preset、plugin完成代码编译。
TypeScript 1件套
实际山,主流IDE(WebStorm、VSCode)等都内置了TypeScript库,可以不用安装TS,只需要配置tsconfig.json
就可以完成代码编写过程中的类型检查(babel编译的时候,不会进行类型检查)。关于这一块,推荐大家阅读另一篇文章:【长文详解】TypeScript与Babel、webpack的关系以及IDE对TS的类型检查 - 知乎 (zhihu.com)。
为了方便的进行类型检查,本样会安装项目级:
代码语言:javascript复制yarn add -D typescript
至此,我们安装了目前基础项目所需要的开发依赖(devDependencies)。
代码语言:javascript复制{

SolidJS 2件套
代码语言:javascript复制yarn add solid-js @solidjs/router
- solid-js:SolidJs核心库;
- @solidjs/router:solidjs官方SPA路由组件。
项目配置
tsconfig.json
项目根目录
代码语言:javascript复制{
"compilerOptions": {
"target": "es2016",
"module": "commonjs",
"esModuleInterop": true,
"forceConsistentCasingInFileNames": true,
"strict": true,
"noEmit": true,
"skipLibCheck": true,
"jsx": "preserve",
"jsxImportSource": "solid-js"
},
"include": [
"src"
]
}
webpack.config.js
项目根目录
代码语言:javascript复制const {resolve} = require('path');
const HtmlWebpackPlugin = require("html-webpack-plugin");
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
module.exports = {
mode: "development",
entry: {
main: resolve(__dirname, 'src', 'index.tsx')
},
output: {
filename: "app.js",
path: resolve(__dirname, 'dist')
},
resolve: {
// webpack 默认只处理js、jsx等js代码
// 为了防止在import其他ts代码的时候,出现
// " Can't resolve 'xxx' "的错误,需要特别配置
extensions: ['.js', '.jsx', '.ts', '.tsx']
},
module: {
rules: [
{
test: /.tsx?/,
use: [
'babel-loader'
],
exclude: /node_moudles/
},
{
test: /.css$/,
use: [
MiniCssExtractPlugin.loader,
'css-loader'
]
},
{
test: /.less$/,
use: [
MiniCssExtractPlugin.loader,
'css-loader',
'less-loader'
]
}
]
},
plugins: [
new HtmlWebpackPlugin({
template: resolve(__dirname, 'public', 'index.html'),
inject: 'body',
favicon: resolve(__dirname, 'public', 'favicon-32x32.png')
}),
new MiniCssExtractPlugin({
filename: 'app.css'
})
],
devServer: {
port: 8080
}
}
.babelrc
项目根目录
代码语言:javascript复制{
"presets": [
"@babel/preset-env",
"@babel/preset-typescript",
"babel-preset-solid"
],
"plugins": [
"@babel/plugin-proposal-object-rest-spread",
"@babel/plugin-proposal-class-properties"
]
}
package.json
添加开发、构建以及类型检查脚本:
代码语言:javascript复制{
... ...
"scripts": {
"typecheck": "tsc",
"start": "webpack-dev-server --config webpack.config.js",
"build": "webpack --config webpack.config.js --mode=production"
},
... ...
}
初始文件创建
app.d.ts
路径:项目根目录/src/app.d.ts。涉及到譬如less模块在ts中使用的类型定义。
代码语言:javascript复制declare module '*.module.less' {
const content: {
[className: string]: any
}
export default content;
}
index.html
路径:项目根目录/public/index.html(主要是与webpack中的HtmlWebpackPlugin.template选项对应)。
代码语言:javascript复制<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png">
<title>SolidJS webpack ts example</title>
</head>
<body>
<div id="app"></div>
</body>
</html>
PS:public目录还创建了一个icon,就不详细说明了。
index.tsx
路径:项目根目录/src/index.tsc
代码语言:javascript复制import {render} from 'solid-js/web';
import styles from './index.module.less';
function HelloWorld() {
return (
<div class={styles.hello}>
<p>Hello World!</p>
</div>
);
}
render(() => <HelloWorld/>, document.querySelector('#app')!)
index.module.less
路径:项目根目录/src/index.module.less
代码语言:javascript复制.hello {
p {
font-size: 16px;
color: #2c4f7c;
}
}
