A write stream constructor that supports a flush function that is called before finish is emitted
npm install flush-write-stream
var writer = require('flush-write-stream')
var ws = writer(write, flush)
ws.on('finish', function () {
console.log('finished')
})
ws.write('hello')
ws.write('world')
ws.end()
function write (data, enc, cb) {
// i am your normal ._write method
console.log('writing', data.toString())
cb()
}
function flush (cb) {
// i am called before finish is emitted
setTimeout(cb, 1000) // wait 1 sec
}If you run the above it will produce the following output
writing hello
writing world
(nothing happens for 1 sec)
finished
Create a new writable stream. Options are forwarded to the stream constructor.
Same as the above except objectMode is set to true per default.
