Lineup stream allows you to combine multiple streams, primitives and promises into a single stream. When the first stream of data ends, the next one starts, and so on, until all buffers are passed.
const line = require('lineup-stream')
const fs = require('fs')
line(
fs.createReadStream(__dirname + '/hello.txt'),
'world and ',
fs.createReadStream(__dirname + '/lorem.txt')
).pipe(process.stdout)You also can lazily create buffers of data by wrapping them in a function and/or promises.
line(
()=> fs.createReadStream(__dirname + '/hello.txt'),
() => 'world'.
new Promise(resolve => {
setTimeout(() => resolve('something'), 2000)
})
).pipe(process.stdout)npm install lineup-stream --save
