Node.js module provides a class which handles a fifo file.
npm: https://www.npmjs.com/package/fifo-js
npm install fifo-jsconst FIFO = require('fifo-js')
let fifo = new FIFO()
fifo.read(console.log.bind(console))
fifo.write('foo')
fifo.close()The constructor creates a new fifo in /tmp/ if a path isn't provided. If a path is provided and there's an existing fifo with that name it uses that one. Otherwise it creates a new one with that name.
let fifo = new FIFO([path])fifo.read(callback)
callback:Function(data:String)fifo.readSync()fifo.read(text => {
// 'text' contains the text which was read from the fifo.
})
let text = fifo.readSync()
// 'text' contains the text which was read from the fifo.This function will read and call the callback for each message until the fifo is closed. If read or readSync is called after a reader is set a FIFOError is thrown.
fifo.setReader(text => {
// 'text' contains the text which was read from the fifo.
})When writing the boolean flag 'trim' can be supplied. This prevents a trailing new line to be added.
fifo.write(data:String, trim:Boolean, callback:Function())fifo.writeSync(data:String, trim:Boolean)fifo.write(text, () => {
// The written text has been read.
})
fifo.writeSync(text, true)
// The written text has been read.fifo.close()
