Node 后端 git 提交规范化处理

创建项目

以 koa 为例

使用 koa-generator 创建项目

# 安装
npm install -g koa-generator
# 创建项目
koa2 test-demo
# 安装依赖
cd test-demo
npm install
# 启动
npm run dev

访问 http://localhost:3000/

创建 .gitignore 忽略掉 node_modules

node_modules/
1

windows 系统 注意把 dev 路径的 斜杠（/）替换成 （\\）

提交前检查

代码格式

使用 eslint + prettier

# 安装
npm install eslint eslint-config-airbnb-base eslint-plugin-import eslint-config-prettier eslint-plugin-prettier -D

创建 .eslintrc.js

module.exports = {
  env: {
    commonjs: true,
    es2020: true,
    node: true,
    jest: true,
    es6: true,
  },
  extends: ['airbnb-base', 'plugin:prettier/recommended'],
  parserOptions: {
    ecmaVersion: 12,
  },
  plugins: ['prettier'],
  rules: {
    'no-unused-vars': 0,
    'no-console': 'off',
    'max-classes-per-file': 0,
    'prettier/prettier': [
      'error',
      { singleQuote: true, semi: false, arrowParens: 'avoid' },
    ],
    'arrow-body-style': 'off',
    'prefer-arrow-callback': 'off',
  },

创建 .eslintignore

node_modules/
1

在跟目录创建一个 src 文件夹，将 public，routes，view 放到 src 下

同时也将 app.js 放到 src 下，并且修改 bin/www 将 const app = require('../app') 改为 const app = require('../src/app')

在 package.json 创建脚本

"script": {
	...,
    "lint": "eslint \"src/**/*.{js,ts}\"",
    "lint-fix": "eslint --fix \"src/**/*.{js,ts}\""
}

# lint 检查
npm run lint

参考

Airbnb JavaScript 代码规范

eslint

代码测试

这里使用 jest

# 安装
npm install --save-dev jest

2

在根目录创建 __test__ 文件夹

在目录下创建 sum.test.js

function sum(a, b) {
  return a + b
}
test('adds 1 + 2 to equal 3', () => {
  expect(sum(1, 2)).toBe(3)
})

# 执行

接口测试

这里使用 supertest

# 安装
npm install supertest --save-dev
# 安装 axios
npm install axios --save-dev

在 __test__ 下创建 apis 文件夹

创建 _server.js 文件，使用 supertest mock 请求接口

const axios = require('axios')
const supertest = require('supertest')

let request
const app = require('../../src/app')

const isTestLocal = process.env.NODE_ENV === 'local'
const isTestRemote = process.env.NODE_ENV === 'remote'

if (isTestLocal) {
  // 通过 supertest 创建服务
  const server = app.callback()
  request = supertest(server)
}

// 测试机 host
const REMOTE_HOST = 'http://localhost:3000'

/**
 * 发送请求
 * @param {*} method
 * @param {*} url
 * @param {*} bodyOrParams
 * @param {*} headers
 */
async function ajax(method = 'get', url = '', bodyOrParams = {}, headers = {}) {
  // 如果有 token 可以在 headers 设置

  let result

  // 本身测试，使用 supertest
  if (isTestLocal) {
    let res
    if (method === 'get') {
      res = await request[method](url).query(bodyOrParams).set(headers)
    } else {
      res = await request[method](url).send(bodyOrParams).set(headers)
    }
    result = res
  }

  // 远程测试机，使用 axios
  if (isTestRemote) {
    const remoteUrl = `${REMOTE_HOST}${url}`
    const conf = {
      method,
      url: remoteUrl,
      headers,
    }
    if (method === 'get') {
      conf.params = bodyOrParams
    } else {
      conf.body = bodyOrParams
    }
    const res = await axios(conf)
    result = res
  }

  // 返回结果
  return result
}

module.exports = {
  async get(url, params, headers) {
    const res = await ajax('get', url, params, headers)
    return res
  },
  async post(url, body, headers) {
    const res = await ajax('post', url, body, headers)
    return res
  },
  async patch(url, body, headers) {
    const res = await ajax('patch', url, body, headers)
    return res
  },
  async del(url, body, headers) {
    const res = await ajax('delete', url, body, headers)
    return res
  },
}

修改脚本

"script": {
    "test:local": "cross-env NODE_ENV=local jest --runInBand --passWithNoTests --colors --forceExit",
    "test:remote": "cross-env NODE_ENV=remote jest --runInBand --passWithNoTests --colors --forceExit"

创建测试文件 user-check.js

const { get } = require('./_server')

it('users/bar 测试', async () => {
  const { text, status } = await get('/users/bar')
  expect(status).toBe(200)
  expect(text).toBe('this is a users/bar response')

npm i pre-commit husky lint-staged --save-dev
# 初始化 husky
npm set-script prepare "husky install"
npm run prepare

在 package.json 中配置 lint-staged

{
    "lint-staged": {
        "*.js": [
            "npm run lint",
            "npm run test:local"

随便修改一个 src 下的 .js 文件，用于测试

会根据 lint-staged 配置的，检查 git 缓存，匹配 *.js 文件，然后执行脚本检查代码

# 推送
git push
