concurrently

concurrently 同时执行多个script​

当多个nodejs项目需要同时启动npm script的时候，可以将多个script运行在同一个shell窗口内，而且可以统一管理打印信息，更好的管理多个node的项目

安装​

npm i -D concurrently

yarn add --dev concurrently

script使用​

package.json

  • 语法：

    "start": "concurrently \"command1 arg\" \"command2 arg\""

  • 示例1

    "scripts": {
        "dev": "concurrently -n=S1,S2 -c=green,yellow \"npm run script1\" \"npm run script2\"",
        "script1": "node xxxx",
        "script2": "node xxxx",
      }

直接调用​

语法：

concurrently "command1 arg" "command2 arg"

部分常用参数：

  • --kill-others / -k

    关闭某些运行中的进程 "name1" "name2"

  • -c / --color

    设置对应shell窗口颜色

  • -n / --name

    设置对应shell在log内显示的名字

  • -r / --raw

    查看对应命令执行的js源文件

导入使用​

语法： concurrently(commands[, options])

  • commands
  • options
const concurrently = require('concurrently');
concurrently([
    'npm:watch-*',
    { command: 'nodemon', name: 'server' },
    { command: 'deploy', name: 'deploy', env: { PUBLIC_KEY: '...' } },
    { command: 'watch', name: 'watch', cwd: path.resolve(__dirname, 'scripts/watchers')}
], {
    prefix: 'name',
    killOthers: ['failure', 'success'],
    restartTries: 3,
    cwd: path.resolve(__dirname, 'scripts'),
}).then(success, failure);
