自动release工具

无聊，写个自动release工具，自动升级版本，自动提交，自动打tag，自动推送到远程仓库。

1. 安装

yarn add chalk semver enquirer  execa

2. package.json

 "scripts": {  
    "release": "node ./scripts/release.js"
  },

3. scripts/release.js

const fs = require('fs')
const path = require('path')
const chalk = require('chalk')
const semver = require('semver')
const { version: currentVersion } = require('../package.json')
const { prompt } = require('enquirer')
const execa = require('execa')

 
//  版本列表
const versionIncrements = [
  'patch',
  'minor',
  'major',
  'prepatch',
  'preminor',
  'premajor',
  'prerelease'
]

// 步骤打印
const step = msg => console.log(chalk.green(msg))

// 增加版本号
const inc = i => semver.inc(currentVersion, i)

// 运行脚本
const run = (bin, args, opts = {}) =>
  execa(bin, args, { stdio: 'inherit', ...opts })

/**
 * 更新版本号
 * @param {string} version
 */
function updatePackage(version) {
  const pkgPath = path.resolve(__dirname, '../package.json')
  const pkg = JSON.parse(fs.readFileSync(pkgPath, 'utf-8'))
  pkg.version = version
  fs.writeFileSync(pkgPath, JSON.stringify(pkg, null, 2) + '\n')
  step(`updated package.json version to ${version}\n`)
}

/**
 * 提交 打标签 推送到远程仓库
 * @param {string} version
 */
async function publish(version) {
  try {
    await run('git', ['add', '-A'])
    await run('git', ['tag', '-a', version, '-m', `Release v${version}`])
    await run('git', ['commit', '-m', `release: v${version}`])
    await run('git', ['push', '--tags'])
    await run('git', ['push'])
    step(`push version to ${version}\n`)
  } catch (error) {
    throw new Error(error)
  }
}

// 主函数
async function main() {
  let version

  const { release } = await prompt({
    type: 'select',
    name: 'release',
    message: 'Select release type',
    choices: versionIncrements.map(i => `${i} (${inc(i)})`).concat(['custom'])
  })

  if (release === 'custom') {
    version = (
      await prompt({
        type: 'input',
        name: 'version',
        message: 'Input custom version',
        initial: version
      })
    ).version
  } else {
    version = release.match(/\((.*)\)/)[1]
  }

  if (!semver.valid(version)) {
    throw new Error(`invalid target version: ${version}`)
  }
  updatePackage(version)
  await publish(version)
}

main().catch(err => {
  console.error(err)
})

4. 运行

yarn release 

5.效果

$ yarn release
yarn run v1.22.17
$ node ./scripts/release.js
? Select release type ... 
> patch (0.1.1)
  minor (0.2.0)
  major (1.0.0)
  prepatch (0.1.1-0)
  preminor (0.2.0-0)
  premajor (1.0.0-0)
  prerelease (0.1.1-0)
  custom
