简单的 Nodejs 插件支持同步、回调、承诺和断言

安装

npm install node-plug

使用示例：

• plugin.js

export const pluginsync = {
  run() {
    console.log('plugin sync dijalankan!')
  },
}

export const plugincallback = {
  run() {
    console.log('plugin callback mulai...')
    settimeout(() => console.log('plugin callback selesai!'), 15)
  },
}

export const pluginpromise = {
  async run() {
    console.log('plugin promise mulai...')
    await new promise((resolve) => settimeout(resolve, 15))
    console.log('plugin promise selesai!')
  },
}

• main.js

import { addplugin, runplugin, test } from 'node-plug'
import { pluginsync, plugincallback, pluginpromise } from './plugin.js'

// menambahkan plugin
addplugin(pluginsync)
addplugin(plugincallback)
addplugin(pluginpromise)

// menjalankan plugin
runplugin()

// melakukan pengujian
test([
  'plugin sync dijalankan!',
  'plugin callback mulai...',
  'plugin promise mulai...',
  'plugin callback selesai!',
  'plugin promise selesai!',
])

上面的代码工作正常，但是如果没有 promise 插件，就会发生错误。

由于没有 promise 插件而导致的错误
为什么会出现错误？因为 runplugin 方法返回一个承诺。

解决方案：
为 promise 插件添加同步和回调插件。

• plugin.js

const pluginsync = {
  run() {
    console.log('plugin sync dijalankan!')
  },
}

const plugincallback = {
  run() {
    console.log('plugin callback mulai...')
  },
}

export const pluginpromise = {
  async run() {
    pluginsync.run()
    plugincallback.run()
    await new promise((resolve) => settimeout(resolve, 15))
    console.log('plugin callback selesai!')
  },
}

// atau
/*const pluginsync = {
  run() {
    console.log('plugin sync mulai...')
  },
}

const plugincallback = {
  run() {
    console.log('plugin callback mulai...')
  },
}

export const pluginpromise = {
  async run() {
    pluginsync.run()
    await new promise((resolve) => settimeout(resolve, 15))
    console.log('plugin sync selesai!')
    plugincallback.run()
    await new promise((resolve) => settimeout(resolve, 15))
    console.log('plugin callback selesai!')
  },
}*/

// atau
/*const pluginsync = {
  run() {
    console.log('plugin sync mulai...')
  },
}

const plugincallback = {
  run() {
    console.log('plugin callback mulai...')
  },
}

export const pluginpromise = {
  async run() {
    pluginsync.run()
    await new promise((resolve) => settimeout(resolve, 15))
    console.log('plugin sync selesai!')
    plugincallback.run()
    await new promise((resolve) => settimeout(resolve, 15))
    console.log('plugin callback selesai!')
    console.log('plugin promise mulai...')
    await new promise((resolve) => settimeout(resolve, 15))
    console.log('plugin promise selesai!')
  },
