搭建基础库~

news 2025/7/3 16:46:00

前言

项目中会用到工具库、函数库以及一些跟框架绑定的组件，如果这些基础模块每个项目都实现一套，维护起来那真的头大，你说呢😉

搭建流程

准备工作

创建文件夹myLib、安装Git以及pnpm

目录大概就系这样子：

myLib
├── .husky
│ ├── commit-msg
│ └── pre-commit
├── packages
│ └── utils
│ ├── lib
│ │ ├── index.cjs.js
│ │ ├── index.esm.js
│ │ └── index.d.ts
│ ├── src
│ │ └── index.ts
│ ├── rollup.config.js
│ ├── tsconfig.json
│ └── package.json
├── .eslintrc.js
├── .prettierrc
├── commitlint.config.js
├── pnpm-workspace.yaml
├── tsconfig.json
└── package.json

配置Typescript

pnpm add -D -w typescript tslib
pnpm tsc --init

tsconfig.json

{
"files": [],
"references": [
{ "path": "./packages/utils" }
]
}

pnpm-workspace.yaml

packages:
- 'packages/*'

package.json

"scripts": {
"postinstall": "husky install",
"lint": "eslint packages/**/*.{ts,js} --fix"
}

子包

tsconfig.json配置

{
"compilerOptions": {
"rootDir": "./src",
"declaration": true,
"declarationDir": "./lib",
"emitDeclarationOnly": true,
"module": "esnext",
"target": "es6",
"moduleResolution": "node",
"strict": true,
"esModuleInterop": true,
"skipLibCheck": true
},
"include": ["src/**/*"]
}

Rollup打包

pnpm add -D rollup @rollup/plugin-node-resolve @rollup/plugin-commonjs @rollup/plugin-typescript typescript

rollup.config.js

import resolve from '@rollup/plugin-node-resolve';
import commonjs from '@rollup/plugin-commonjs';
import typescript from '@rollup/plugin-typescript';

export default {
input: "src/index.ts",
output: [
{
file:"lib/index.cjs.js",
format:"cjs",
},
{
file:"lib/index.esm.js",
format:"esm",
},
],
plugins:[
resolve(),
commonjs(),
typescript()
]
};

package.json

"scripts": {
"build": "rollup -c"
}

git commit 验证

记得用git先初始化下仓库

pnpm add -D -w husky @commitlint/{config-conventional,cli}
pnpm husky install

pnpm dlx husky-init --pm=pnpm

npx husky add .husky/commit-msg 'npx --no-install commitlint --edit "$1"'

commitlint.config.js

module.exports = {
extends: ['@commitlint/config-conventional']
};

配置Eslint和Prettier

pnpm add -D -w eslint prettier eslint-config-prettier eslint-plugin-prettier

eslint.config.js

const path = require('path');
const { ESLint } = require('eslint');
const tsParser = require('@typescript-eslint/parser');
const tsPlugin = require('@typescript-eslint/eslint-plugin');
const prettierPlugin = require('eslint-plugin-prettier');

module.exports = [
{
files: ['packages/**/src/**/*.{ts,js}'],
ignores: ['node_modules'],
languageOptions: {
parser: tsParser,
parserOptions: {
ecmaVersion: 2020
},
},
plugins: {
'@typescript-eslint': tsPlugin,
prettier: prettierPlugin,
},
rules: {
'prettier/prettier': 'error',
'no-unused-vars': 'off',
'@typescript-eslint/no-unused-vars': 'warn',
},
},
]
