| 10 | + |
| 11 | +## 概览 |
| 12 | + |
| 13 | +本系列文章主要是开发组件库[dora-ui](https://github.com/worldzhao/dora-ui)过程中的一些经验总结,大致包含以下内容: |
| 14 | + |
| 15 | +- prepare: 组件库前期开发准备工作。`eslint`/`commit lint`/`typescript`等等; |
| 16 | +- dev: 使用[docz](https://github.com/doczjs/docz)进行开发调试以及文档编写; |
| 17 | +- build: ~~`umd`~~/`cjs`/`esm`、types、polyfill 以及按需加载; |
| 18 | +- deploy: 使用[now](https://zeit.co/home)部署文档站点; |
| 19 | +- publish: 发布组件库至`npm`; |
| 20 | +- others: 组件测试 |
| 21 | + |
| 22 | +注意:`.gitignore`、`.eslintignore`以及`.editorconfig`等更多文件可在[chapter-1](https://github.com/worldzhao/react-ui-library-tutorial/tree/chapter-1/before-start)章节代码中获取。 |
| 23 | + |
| 24 | +## 初始化项目 |
| 25 | + |
| 26 | +新建一个`happy-ui`文件夹,并初始化。 |
| 27 | + |
| 28 | +```bash |
| 29 | +mkdir happy-ui |
| 30 | + |
| 31 | +cd happy-ui |
| 32 | + |
| 33 | +npm init --y |
| 34 | + |
| 35 | +mkdir components && cd components && touch index.ts # 新建源码文件夹以及入口文件 |
| 36 | + |
| 37 | +``` |
| 38 | + |
| 39 | +## 代码规范 |
| 40 | + |
| 41 | +此处直接使用[@umijs/fabric](https://github.com/umijs/fabric)的配置。 |
| 42 | + |
| 43 | +```bash |
| 44 | +yarn add @umijs/fabric --dev |
| 45 | + |
| 46 | +yarn add prettier --dev # 因为@umijs/fabric没有将prettier作为依赖 所以我们需要手动安装 |
| 47 | +``` |
| 48 | + |
| 49 | +**.eslintrc.js** |
| 50 | + |
| 51 | +```js |
| 52 | +module.exports = { |
| 53 | + extends: [require.resolve('@umijs/fabric/dist/eslint')], |
| 54 | +}; |
| 55 | +``` |
| 56 | + |
| 57 | +**.prettierrc.js** |
| 58 | + |
| 59 | +```js |
| 60 | +const fabric = require('@umijs/fabric'); |
| 61 | + |
| 62 | +module.exports = { |
| 63 | + ...fabric.prettier, |
| 64 | +}; |
| 65 | +``` |
| 66 | + |
| 67 | +**.stylelintrc.js** |
| 68 | + |
| 69 | +```js |
| 70 | +module.exports = { |
| 71 | + extends: [require.resolve('@umijs/fabric/dist/stylelint')], |
| 72 | +}; |
| 73 | +``` |
| 74 | + |
| 75 | +想自行配置的同学可以参考以下文章: |
| 76 | + |
| 77 | +- [Linting Your React+Typescript Project with ESLint and Prettier!](https://medium.com/@dors718/linting-your-react-typescript-project-with-eslint-and-prettier-2423170c3d42) |
| 78 | +- [使用 ESLint+Prettier 规范 React+Typescript 项目 ](https://zhuanlan.zhihu.com/p/62401626) |
| 79 | + |
| 80 | +## Commit Lint |
| 81 | + |
| 82 | +进行`pre-commit`代码规范检测。 |
| 83 | + |
| 84 | +```bash |
| 85 | +yarn add husky lint-staged --dev |
| 86 | +``` |
| 87 | + |
| 88 | +**package.json** |
| 89 | + |
| 90 | +```json |
| 91 | +"lint-staged": { |
| 92 | + "components/**/*.ts?(x)": [ |
| 93 | + "prettier --write", |
| 94 | + "eslint --fix", |
| 95 | + "git add" |
| 96 | + ], |
| 97 | + "components/**/*.less": [ |
| 98 | + "stylelint --syntax less --fix", |
| 99 | + "git add" |
| 100 | + ] |
| 101 | +}, |
| 102 | +"husky": { |
| 103 | + "hooks": { |
| 104 | + "pre-commit": "lint-staged" |
| 105 | + } |
| 106 | +} |
| 107 | +``` |
| 108 | + |
| 109 | +进行 Commit Message 检测。 |
| 110 | + |
| 111 | +```bash |
| 112 | +yarn add @commitlint/cli @commitlint/config-conventional commitizen cz-conventional-changelog --dev |
| 113 | +``` |
| 114 | + |
| 115 | +新增`.commitlintrc.js`写入以下内容 |
| 116 | + |
| 117 | +```js |
| 118 | +module.exports = { extends: ['@commitlint/config-conventional'] }; |
| 119 | +``` |
| 120 | + |
| 121 | +package.json 写入以下内容: |
| 122 | + |
| 123 | +```json |
| 124 | +// ... |
| 125 | +"scripts": { |
| 126 | + "commit": "git-cz", |
| 127 | +} |
| 128 | +// ... |
| 129 | +"husky": { |
| 130 | + "hooks": { |
| 131 | + "commit-msg": "commitlint -E HUSKY_GIT_PARAMS", |
| 132 | + "pre-commit": "lint-staged" |
| 133 | + } |
| 134 | +}, |
| 135 | +"config": { |
| 136 | + "commitizen": { |
| 137 | + "path": "cz-conventional-changelog" |
| 138 | + } |
| 139 | +} |
| 140 | +``` |
| 141 | + |
| 142 | +后续使用 `yarn commit` 替代 `git commit`生成规范的 Commit Message,当然为了效率你可以选择手写,但是要符合规范。 |
| 143 | + |
| 144 | +## TypeScript |
| 145 | + |
| 146 | +```bash |
| 147 | +yarn add typescript --dev |
| 148 | +``` |
| 149 | + |
| 150 | +新建`tsconfig.json`并写入以下内容 |
| 151 | + |
| 152 | +```json |
| 153 | +{ |
| 154 | + "compilerOptions": { |
| 155 | + "allowJs": false, |
| 156 | + "target": "esnext", |
| 157 | + "module": "commonjs", |
| 158 | + "jsx": "react", |
| 159 | + "declaration": true, |
| 160 | + "outDir": "types", |
| 161 | + "strict": true, |
| 162 | + "moduleResolution": "node", |
| 163 | + "allowSyntheticDefaultImports": true, |
| 164 | + "esModuleInterop": true |
| 165 | + }, |
| 166 | + "include": ["components"] |
| 167 | +} |
| 168 | +``` |
| 169 | + |
| 170 | +## 测试 |
| 171 | + |
| 172 | +在`components`文件夹下新建`alert`文件夹,目录结构如下: |
| 173 | + |
| 174 | +``` |
| 175 | +alert |
| 176 | + ├── alert.tsx # 源文件 |
| 177 | + ├── index.ts # 入口文件 |
| 178 | + ├── interface.ts # 类型声明文件 |
| 179 | + └── style |
| 180 | + ├── index.less # 样式文件 |
| 181 | + └── index.ts # 样式文件里为什么存在一个index.ts - 按需加载样式 管理样式依赖 后面章节会提到 |
| 182 | +``` |
| 183 | + |
| 184 | +安装`React`相关依赖: |
| 185 | + |
| 186 | +```bash |
| 187 | +yarn add react react-dom @types/react @types/react-dom --dev # 开发时依赖,宿主环境一定存在 |
| 188 | + |
| 189 | +yarn add prop-types # 运行时依赖,宿主环境可能不存在 安装本组件库时一起安装 |
| 190 | +``` |
| 191 | + |
| 192 | +> 此处依旧安装了`prop-types`这个库,因为无法保证宿主环境也使用`typescript`,从而能够进行静态检查,故使用`prop-types`保证`javascript`用户也能得到友好的运行时报错信息。 |
| 193 | +
|
| 194 | +**components/alert/interface.ts** |
| 195 | + |
| 196 | +```js |
| 197 | +export type Kind = 'info' | 'positive' | 'negative' | 'warning'; |
| 198 | +export type KindMap = Record<Kind, string>; |
| 199 | + |
| 200 | +export interface AlertProps { |
| 201 | + /** |
| 202 | + * Set this to change alert kind |
| 203 | + * @default info |
| 204 | + */ |
| 205 | + kind?: 'info' | 'positive' | 'negative' | 'warning'; |
| 206 | +} |
| 207 | +``` |
| 208 | + |
| 209 | +**components/alert/alter.tsx** |
| 210 | + |
| 211 | +```jsx |
| 212 | +import React from 'react'; |
| 213 | +import t from 'prop-types'; |
| 214 | + |
| 215 | +import { AlertProps, KindMap } from './interface'; |
| 216 | + |
| 217 | +const prefixCls = 'happy-alert'; |
| 218 | + |
| 219 | +const kinds: KindMap = { |
| 220 | + info: '#5352ED', |
| 221 | + positive: '#2ED573', |
| 222 | + negative: '#FF4757', |
| 223 | + warning: '#FFA502', |
| 224 | +}; |
| 225 | + |
| 226 | +const Alert: React.FC<AlertProps> = ({ children, kind = 'info', ...rest }) => ( |
| 227 | + <div |
| 228 | + className={prefixCls} |
| 229 | + style={{ |
| 230 | + background: kinds[kind], |
| 231 | + }} |
| 232 | + {...rest} |
| 233 | + > |
| 234 | + {children} |
| 235 | + </div> |
| 236 | +); |
| 237 | + |
| 238 | +Alert.propTypes = { |
| 239 | + kind: t.oneOf(['info', 'positive', 'negative', 'warning']), |
| 240 | +}; |
| 241 | + |
| 242 | +export default Alert; |
| 243 | +``` |
| 244 | + |
| 245 | +**components/alert/index.ts** |
| 246 | + |
| 247 | +```js |
| 248 | +import Alert from './alert'; |
| 249 | + |
| 250 | +export default Alert; |
| 251 | + |
| 252 | +export * from './interface'; |
| 253 | +``` |
| 254 | + |
| 255 | +**components/alert/style/index.less** |
| 256 | + |
| 257 | +```less |
| 258 | +@popupPrefix: happy-alert; |
| 259 | + |
| 260 | +.@{popupPrefix} { |
| 261 | + padding: 20px; |
| 262 | + background: white; |
| 263 | + border-radius: 3px; |
| 264 | + color: white; |
| 265 | +} |
| 266 | +``` |
| 267 | + |
| 268 | +**components/alert/style/index.ts** |
| 269 | + |
| 270 | +```js |
| 271 | +import './index.less'; |
| 272 | +``` |
| 273 | + |
| 274 | +**components/index.ts** |
| 275 | + |
| 276 | +```js |
| 277 | +export { default as Alert } from './alert'; |
| 278 | +``` |
| 279 | + |
| 280 | +> 此处组件参考的`docz`项目`typescript`以及`less`示例。 |
| 281 | +
|
| 282 | +git 一把梭,可以看到控制台已经进行钩子检测了。 |
| 283 | + |
| 284 | +```bash |
| 285 | +git add . |
| 286 | + |
| 287 | +yarn commit # 或 git commit -m'feat: chapter-1 准备工作' |
| 288 | + |
| 289 | +git push |
| 290 | +``` |
| 291 | + |
| 292 | +准备工作结束,欢迎指点交流。 |
| 293 | + |
| 294 | +To be Continued... |
