RxHotModule

When in the presence of Hot Module Replacement, export an Observable.

Example

// hot.js
import rxHot from './rxhot'

export default rxHot (module) ('hello world')

// entry.js
import hot from './hot'

if (typeof hot.subscribe === 'function') {
  // Module is hot
  hot
    .map(phrase => phrase.length)
    .subscribe(console.log)
} else {
  console.log(hot.length)
}

If HMR is disabled, rxHot returns the data object by default. To change this behavior and always return an Observable, pass the {alwaysRx: true} to rxHot

// hot.js
import rxHot from './rxhot'

export default rxHot (module, {alwaysRx: true}) ('hello world')

// entry.js
import hot from './hot'

// Module is always Observable
hot
  .map(phrase => phrase.length)
  .subscribe(console.log)
