一、创建项目
- 1、在github上创建一个项目,然后拉取至本地,进入项目目录
- 2、执行
npm init
生成json文件 - 3、创建
src/index.ts
入口文件和src/isObject.ts
工具方法
· src/index.ts
export { default as isObject } from './isObject'
· src/isObject.ts
/*** @description 判断是否为对象* @param {*} variable* @returns {Boolean}*/
function isObject(variable: any): boolean {return Object.prototype.toString.call(variable) === '[object Object]'
}export default isObject
二、配置Rollup打包
- 1、安装rollup和typescript
npm install rollup typescript -D
- 2、创建
tsconfig.json
配置文件:
{"compilerOptions": {"target": "es5" /* 编译目标 */,"module": "commonjs" /* 项目模块类型 */,"lib": ["ES2018", "DOM"],"allowJs": true /* 是否允许js代码 */,"checkJs": true /* 检查js代码错误 */,"declaration": true /* 自动创建声明文件(.d.ts) */,"declarationDir": "./lib/types" /* 声明文件目录 */,"sourceMap": true /* 自动生成sourcemap文件 */,"outDir": "lib" /* 编译输出目录 */,"rootDir": "./src" /* 项目源码根目录,用来控制编译输出的目录结构 */,"strict": true /* 启用严格模式 */},"include": ["src/*.ts"],"exclude": ["node_modules", "lib"],
}
- 3、安装rollup插件
· 处理路径npm install @rollup/plugin-node-resolve -D
· 支持tsnpm install @rollup/plugin-typescript -D
· 处理commonjsnpm install @rollup/plugin-commonjs -D
· 压缩umd规范的输出文件npm install @rollup/plugin-terser -D
· 重新打包代码清理npm install rollup-plugin-delete -D
- 4、创建
rollup.config.js
配置文件:
const resolve = require('@rollup/plugin-node-resolve') // 处理npm包的相关引入依赖
const typescript = require('@rollup/plugin-typescript')
const commonjs = require('@rollup/plugin-commonjs') // 将commonJS的语法转化成ES2015 Module
const terser = require('@rollup/plugin-terser') // 代码压缩
const del = require('rollup-plugin-delete')module.exports = [{input: './src/index.ts',output: [{dir: 'lib',format: 'cjs',entryFileNames: '[name].cjs.js',sourcemap: true, // 是否输出sourcemap},{dir: 'lib',format: 'esm',entryFileNames: '[name].esm.js',sourcemap: true, // 是否输出sourcemap},{dir: 'lib',format: 'umd',entryFileNames: '[name].umd.js',name: 'Umob', // umd模块名称,自动挂载至windowsourcemap: true,plugins: [terser()],},],plugins: [del({ targets: 'lib/*' }),resolve(),commonjs(),typescript({ module: 'ESNext' }),],},
]
- 5、在package.json配置的scripts中增加构建脚本
"build": "rollup -c"
- 6、执行
npm run build
三、手动发布
- 1、完善配置文件
· .npmignore
src/
node_modules/
.babelrc
.gitignore
· package.json
{"name": "your project name","version": "0.0.1","description": "your project description","browser": "lib/index.esm.js", // umd规范"module": "lib/index.esm.js", // 使用esm时,会使用这个包"jsnext:main": "lib/index.esm.js", // 社区规范"main": "lib/index.cjs.js", // 当使用commonjs规范时会使用这个包"types": "lib/types/index.d.ts", // ts类型文件"files": ["lib"], // 用于约定在发包的时候NPM 会发布包含的文件和文件夹。"scripts": {"build": "rollup -c",},"keywords": ["modules","stdlib","util"],"author": "Unknow","license": "MIT","devDependencies": {"@rollup/plugin-commonjs": "^25.0.0","@rollup/plugin-node-resolve": "^15.1.0","@rollup/plugin-terser": "^0.4.3","@rollup/plugin-typescript": "^11.1.1","rollup": "^3.23.0","rollup-plugin-delete": "^2.0.0","tslib": "^2.5.2","typescript": "~5.0.4"},"repository": {"type": "git","url": "https://github.com/xxx.git"}
}
- 2、登陆npm账号(没有去官网注册一个)
npm login
- 3、查看是否登录成功
npm who am i
- 4、将包推送至服务器
npm publish
- 5、package中的name不可与他人重复,否则会提示权限问题。如果使用
@[scope]/package
的命名形式,[scope]需要填账户名称
四、安装jest单元测试
- 1、安装
install jest ts-jest @types/jest jest-environment-jsdom -D
- 2、根目录下新增配置文件:
· .jest.config.js
/** @type {import('ts-jest').JestConfigWithTsJest} */module.exports = {preset: 'ts-jest',testEnvironment: 'jsdom', clearMocks: true,collectCoverage: true,coverageDirectory: 'coverage',coverageProvider: 'v8',moduleFileExtensions: ["ts", "js"],// 配置测试环境uatestEnvironmentOptions: {userAgent: 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/108.0.0.0 Safari/537.36',},
}
3、在 package.json
配置的scripts中增加测试脚本 "test": "jest"
4、编写单元测试:
· src/tests/isObject.test.ts
import { isObject } from '../index'describe('isObject: ', () => {it('Determine the type of number', async () => {expect(isObject(1)).toEqual(false)})it('Determine the type of string', async () => {expect(isObject('1')).toEqual(false)})it('Determine the type of boolean', async () => {expect(isObject(false)).toEqual(false)})it('Determine the type of array', async () => {expect(isObject([])).toEqual(false)})it('Determine the type of undefined', async () => {expect(isObject(undefined)).toEqual(false)})it('Determine the type of null', async () => {expect(isObject(null)).toEqual(false)})it('Determine the type of symbol', async () => {const symbol2 = Symbol('this is symbol')expect(isObject(symbol2)).toEqual(false)})it('Determine the type of empty object', async () => {expect(isObject({})).toEqual(true)})
})
- 5、增加单文件单元测试命令,用于团队本地开发测试使用
"test:single": "node env-dependencies.js"
- 6、在根目录下创建
env-dependencies.js
和.env.json
文件
· env-dependencies.js
const execSync = require('child_process').execSync
const pkg = require('./package.json')
const fs = require('fs')
const path = require('path')
const JSON_FILE_NAME = '.env.json'
const DEFAULT_TEST_FILE_NAME = 'isObject'
const filePath = path.join(__dirname, JSON_FILE_NAME) // 文件路径// 检查文件是否已存在
if (!fs.existsSync(filePath)) {const content = {TEST_FILE_NAME: DEFAULT_TEST_FILE_NAME,}const jsonContent = JSON.stringify(content, null, 4)try {fs.writeFileSync(filePath, jsonContent, 'utf8')} catch (err) {console.error('写入文件时发生错误:', err)}
}if (!pkg.envDependencies) {process.exit(0)
}let env = Object.assign({}, process.env)try {Object.assign(env, require('./' + JSON_FILE_NAME))
} catch (err) {console.log('Could not read or parse JSON_FILE_NAME.')
}if (typeof pkg.envDependencies.params === 'undefined') {console.log('pkg.envDependencies.params not found or empty. Passing.')process.exit(0)
}if (!Array.isArray(pkg.envDependencies.params) ||!(pkg.envDependencies.params.every(item => typeof item === 'string'))
) {throw new Error('pkg.envDependencies.params should have a signature of String[]')
}const parsed = pkg.envDependencies.params.map(item => item.replace(/${([0-9a-zA-Z_]*)}/g, (_, varName) => {if (typeof env[varName] === 'string') {return env[varName]} else {throw new Error('Could not read env variable ' + varName + ' in params ' + item)}
})).join(' ')try {execSync(parsed, { stdio: [0, 1, 2] })process.exit(0)
} catch (err) {}
· .env.json
{"TEST_FILE_NAME": "isObject"
}
· 在package.json中增加字段
"envDependencies": {"params": ["jest ./src/__tests__/${TEST_FILE_NAME}.test.ts --coverage --collectCoverageFrom=./src/${TEST_FILE_NAME}.ts"]
}
- 7、配置
.gitignore
和.npmignore
,忽略.env.json
的提交 - 8、运行
npm run test:single
,可测试.env.json
中TEST_FILE_NAME
字段配置的文件名
五、安装eslint
- 1、安装
install eslint eslint-config-airbnb @typescript-eslint/eslint-plugin @typescript-eslint/parser -D
- 2、新增配置文件:
· .eslintrc.js
module.exports = {root: true,env: {browser: true,node: true,},extends: ['airbnb','plugin:@typescript-eslint/recommended',],parser: '@typescript-eslint/parser',plugins: ['@typescript-eslint',],globals: {NodeJS: 'readonly',},settings: {'import/resolver': {node: {extensions: ['.js', '.ts']},},react: {version: '0.0.0',},},rules: {// 添加自定义规则'no-console': 2,'no-debugger': 2,},
}
- 3、增加lint命令
"lint": "eslint --ext .ts src/"
- 4、运行
npm run lint
- 5、安装husky,在代码提交前自动执行eslint校验
npm install husky --save-dev
- 6、启用git钩子
npx husky install
- 7、向package.json文件设置prepare脚本
npm pkg set scripts.prepare="husky install"
- 8、新增一个pre-commit钩子
npx husky add .husky/pre-commit "npm run lint"
六、自动化发布
-
1、在npm中生成 Access Tokens
-
2、将token复制到github对应仓库的秘钥中
-
3、设置一个变量名
NPM_ACCESS_TOKEN
,用于之后CI中通过secrets.NPM_ACCESS_TOKEN
获取 -
4、在根目录下创建
.github/workflows/node.js.yml
配置文件
name: Build CIon:push:branches: [ "main" ]jobs:build:runs-on: ubuntu-latestpermissions:contents: writestrategy:matrix:node-version: [16.20.0]steps:- name: 检出分支uses: actions/checkout@v3- name: 初始化缓存uses: actions/cache@v3id: cache-dependencieswith:path: node_moduleskey: ${{runner.OS}}-${{hashFiles(\'**/package-lock.json\')}}- name: Use Node.js ${{ matrix.node-version }}# 使用actions/setup-node插件uses: actions/setup-node@v3with:# node版本node-version: ${{ matrix.node-version }}cache: 'npm'- run: npm ci# 生成测试覆盖率- run: npm run test- run: npm run build- name: 上报测试覆盖率id: coverRateuses: coverallsapp/github-action@masterwith:github-token: ${{ secrets.GITHUB_TOKEN }}- name: 读取版本号id: versionuses: notiz-dev/github-action-json-property@releasewith:# 读取版本号path: './package.json'prop_path: 'version'- name: 打印版本号run: echo ${{steps.version.outputs.prop}}- name: 创建Releaseuses: softprops/action-gh-release@v1with:files: |./lib/index.umd.js./lib/index.esm.js./lib/index.cjs.jsname: v${{steps.version.outputs.prop}}tag_name: v${{steps.version.outputs.prop}}env:GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}- name: 发布NPM包run: |npm config set //registry.npmjs.org/:_authToken=$NPM_TOKENnpm publishenv:# 配置 npm access token 环境变量NPM_TOKEN: ${{secrets.NPM_ACCESS_TOKEN}}
七、为readme添加测试覆盖率badge
- 1、进入coveralls官网,授权 github,https://coveralls.io/
- 2、授权后点击左侧侧边栏的
ADD REPOS
,将需要生成badge徽章的库设置为on - 3、在readme中添加连接即可查看
<img src='https://coveralls.io/repos/github/{用户名}/{仓库名}/badge.svg?branch=main' />
八、整体目录结构
- .github- workflows- xx.yml # git Actions
- .husky_pre-commit # git提交钩子
- src- __test__ # 单元测试- index.ts # 入口文件- isObject.ts
- .env.json # 环境变量配置

- .eslintrc.js
- .gitignore
- .npmignore
- env-dependencies.js # 环境变量读取脚本
- jest.config.js
- package.json
- rollup.config.js
- tsconfig.json
九、完整package.json配置
