Linux named pipes in NodeJS (mkfifo)
npm install @atroche/named-pipeLinux named pipes in NodeJS (mkfifo)
``bash`
npm install named-pipe
This library creates Linux pipes without the use of a C++ binding and through shell execution.
None! your shell needs to support mkfifo though. Try mkfifo --help in a shell and see if you have access to it.
You can use Linux pipes for a very simple RPC. note that Linux pipes by default will BLOCK if no other process is reading from the other end!.
In your Node process:
`JS${new Date().toISOString()}: hello fron Node!\n
const path = '/tmp/test';
await mkfifoPromise(path);
setInterval(
appendFileSync.bind(null, path,
),
1000
);
And in a separate shell:
`bash`
$ tail -f /tmp/test
2018-03-11T05:37:16.328Z: hello fron Node!
2018-03-11T05:37:16.328Z: hello fron Node!

Full source code of this example is located in example.js.
This library provides three variants of mkfifo in NodeJS.
Signature:
`TS`
const mkfifoSync: (path: string, permission?: number = 644);
Usage:
`JS`
const { mkfifoSync } = require('named-pipe');
mkfifoSync('/tmp/fifo');
`TS`
const mkfifoPromise: (path: string, permission?: number = 644);
Usage:
`JS`
const { mkfifoPromise } = require('named-pipe');
await mkfifoPromise('/tmp/fifo').catch(console.error);
`TS`
const mkfifo: (path: string, permission?: number = 644, callback: Function);
Usage:
`JS``
const { mkfifo } = require('named-pipe');
mkfifo('/tmp/fifo', 644, (error) => {
// 'error' will be non-null if unable to create the pipe
});
