infinite-file-stream

Minimalistic infinite file stream.

An easy way to create readable stream that loops over file contents infinitely.

Install

npm i infinite-file-stream

Use

• Pass in file [string] and optional encoding [string] options.
• Use it as a readable node Stream

Can pipe

const IFS = require('infinite-file-stream');
 
const stream = new FileStreamer({ file });
stream.pipe(process.stdout);
 

Or, emit events

const IFS = require('infinite-file-stream');
 
const stream = new FileStreamer({ file });
stream.on('data' console.log.bind(console));

Useful with test event servers to emit data per line

const IFS = require('infinite-file-stream');
const through = require('through');
const koa = require('koa');
const app = koa();
 
const file = './some/sample.txt';
 
app.use(function *response() {
  this.type = 'text/event-stream; charset=utf-8';
  this.set('Cache-Control', 'no-cache');
  this.set('Connection', 'keep-alive');
 
  this.body = (new IFS({ file }))
    .on('error', console.error.bind(console))
    .pipe(es.split('\n'))
    .pipe(through(send, end));
 
  const socket = this.socket;
  function close() {
    socket.removeListener('error', close);
    socket.removeListener('close', close);
  }
  socket.on('error', close);
  socket.on('close', close);
});
 
app.listen(9000);
