dl6 v0.3.0

dl6 -- Dynamic Loading Module for Node.js

dl6.require() delay the loading until the first time you call it.

dl6.require() reload your module automatically when the module is modified !

We use the es6 proxy and fs.watch() to implement the dl6 package.

Install

$ npm i dl6

Example

File: dl6ex.js

const dl6 = require('dl6')
const fs = require('fs')

function sleep (ms) {
  return new Promise(resolve => setTimeout(resolve, ms))
}

async function main () {
  fs.writeFileSync('cat.js', `
  module.exports = {
    say: () => 'meow'
  }
  `)

  const cat = dl6.dload(__dirname, 'cat')
  console.log('cat=', cat)
  console.log(cat.say())
  console.log('cat=', cat)

  fs.writeFileSync('cat.js', `
  module.exports = {
    say: () => 'hello'
  }
  `)
  await sleep(1000)
  console.log(cat.say())
  dl6.end()
}

main().catch((error) => console.log(error))

Run:

$ node dl6ex.js
cat= {}
call D:\ccc\code\js\dl6\example\cat : say
meow
cat= { say: [Function: say] }
call D:\ccc\code\js\dl6\example\cat : say
