Simpel plugin Node.js mendukung sync, callback, promise, dan assert.

Instalasi

npm install node-plug
Enter fullscreen mode Exit fullscreen mode

Contoh penggunaan:

  • 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!')
  },
}
Enter fullscreen mode Exit fullscreen mode
  • 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!',
])
Enter fullscreen mode Exit fullscreen mode

Kode di atas berjalan dengan baik tapi jika tanpa plugin promise maka akan terjadi error.

Error karena tanpa plugin promise
Kenapa terjadi error? Karena method runPlugin mengembalikan promise.

Solusi:
Tambahkan plugin sync dan callback ke plugin promise.

  • 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!')
  },
