总体概括
因为搭建的是node项目， 所以比前端项目搭建要简单很多。
从以下因素考虑
-
装包问题
- yarn
- 配置项：
.yarnrc 、.npmrc .gitignore
-
代码规范
- eslint
- prettier
- commititlint
- 每次提交自动检测eslint\commitLint
-
测试
- jest、ts-jest
-
代码构建
- tsconfig
- typeings
装包问题
这个问题比较简单没有什么好说的， 推荐 yarn , 如果是非常复杂的项目， 推荐使用 yarn/workSpace + lerna 组合拳， 爽歪歪。
.yarnrc:
registry "https://registry.npm.taobao.org"npmrc:
registry = https://registry.npm.taobao.org.gitignore:

package-lock.json代码规范
集成eslint、prettier、recommended
.eslintrc.js:
module.exports = {
parser: '@typescript-eslint/parser',
parserOptions: {
ecmaFeatures: {
jsx: true,
},
project: './tsconfig.json',
},
plugins: ['@typescript-eslint'],
extends: [
'prettier',
'prettier/@typescript-eslint',
'plugin:@typescript-eslint/recommended',
'plugin:@typescript-eslint/eslint-recommended',
'plugin:@typescript-eslint/recommended-requiring-type-checking',
'plugin:prettier/recommended',
],
env: {
node: true,
browser: false,
},
rules: {
'@typescript-eslint/no-var-requires': 1,
'@typescript-eslint/explicit-function-return-type': 2,
'@typescript-eslint/explicit-member-accessibility': 2,
'no-unused-vars': 2,
semi: [2, 'always', { omitLastInOneLineBlock: true }],
},
};.prettierrc:
{
"singleQuote": true,
"trailingComma": "all",
"printWidth": 140,
"semi": true,
"bracketSpacing": true,
"jsxBracketSameLine": true,
"arrowParens": "avoid",
"requirePragma": false,
"proseWrap": "preserve",
"htmlWhitespaceSensitivity": "ignore",
"tabWidth": 2
}集成commitlint - commitlint.config.js:
module.exports = {
extends: ['@commitlint/config-conventional'],
rules: {
'type-enum': [2, 'always', ['feat', 'fix', 'docs', 'style', 'refactor', 'test', 'chore', 'revert']],
'subject-full-stop': [0, 'never'],
'subject-case': [0, 'never'],
},
};每次提交自动检测eslint\commitLint：
可以看这篇文章：使用husky、prettier、lint、commitlint构建规范化项目实践
需要安装的依赖包：yarn add @commitlint/cli @commitlint/config-conventional @commitlint/prompt-cli commitizen lint-staged husky --dev
package.json
{
"scripts": {
"type-check": "tsc",
"prettier": "prettier --write",
"commit": "commit"
},
"config": {
"commitizen": {
"path": "cz-conventional-changelog"
}
},
"husky": {
"hooks": {
"pre-commit": "lint-staged",
"commit-msg": "commitlint -E HUSKY_GIT_PARAMS"
}
},
"lint-staged": {
"**/*.{js,ts,tsx}": [
"yarn prettier",
"git add"
],
"**/*.{ts,spec.js,tsx}": [
"eslint --fix",
"git add"
]
}
}测试部分
装包：yarn add @types/jest jest ts-jest --dev
具体可以看看看这个文章： jest测试基础
jest.config.js:
module.exports = {
transform: {
'^.+\ .tsx?$': 'ts-jest',
},
testRegex: '(/__tests__/.*|(\ .|/)(test|spec))\ .(jsx?|tsx?)$',
moduleFileExtensions: ['ts', 'tsx', 'js', 'jsx', 'json', 'node'],
};代码构建
