pear-pipe

Pear parent app connected bare-pipe

Usage

const pipe = require('pear-pipe')()
if (pipe === null) {
  console.log('Not a child app')
} else {
  pipe.on('data', console.log)
  pipe.write(Buffer.from('some data))
}

API

const pipe = require('pear-pipe') | import pipe from 'pear-pipe' pipe() -> PearPipe|null

Returns null if the app doesn't have a parent app.

If an app has been run with pear-run, returns PearPipe instance.

PearPipe inherits from bare-pipe (which inherits from Duplex) and extends it with a couple of methods and properties.

pipe.autoexit = true

Whether to automatically exit when pipe emits the end event.

Default to true for common usage, which is creating a worker and expecting it to exit once the parent ends the pipe. Set to false to opt-in to graceful close strategy where all handles are closed before process exits. If using pipe.autoexit = false be sure to close the writable side of the pipe when the readable side is closed by the parent: pipe.on('end', () => pipe.end()).
