Detect module's update recursively on nodejs.

// module.js
module.exports = require('./foo') + require('./bar')

const makeHotRequire = require('hot-module-require')
const hotRequire = makeHotRequire(__dirname)

let mExports = require('./module')

hotRequire.accept(['./module'], (oldModule, path) => {
  // Do something here 
  // when './module' module or submodules('./foo', './bar'') be detected changed.
  let newExports = require('./module') 
})


// Or use it like follows
const hotModuleGetter = hotRequire('./module')
hotModuleGetter() // Returns the already updated `require('./module')``

hotModuleGetter.remove() // Calls `remove` for interrupting detect updated
