Simpel 外掛程式 Node.js 同步、回呼、承諾、斷言。

安裝

npm install node-plug

使用範例：

• 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!',
])

上面的程式碼運作良好，但是如果沒有 Promise 插件，就會出現錯誤。

由於沒有 Promise 外掛程式而導致的錯誤
為什麼會出現錯誤？因為 runPlugin 方法回傳一個承諾。

解：
為 Promise 外掛程式新增同步和回呼插件。

• 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!')
  },
}*/
