A simple transform stream that can log a tick every time data is pushed through a pipe
npm install tick-stream
A simple transform stream that can log a tick every time data is pushed through a pipe.
You have a long running pipe of streams doing stuff. It's very common that, while the
pipe is being processed, you want to see some progress. How many times did you have
to implement your own stream just to console log some sort of progress?
Well, now you don't have to do that anymore and you can simply use tick-stream for that:
``JavaScript
const TickStream = require('tick-stream')
// initialize stream1, stream2 and stream3 somehow here
stream1
.pipe(stream2)
.pipe(stream3)
.pipe(new TickStream())
`
This code will produce an output similar to this:
`plain`
tick: 0
tick: 1
tick: 2
tick: 3
Every line is outputted once a chunk of data has been processed by the stream.
With NPM:
`bash`
npm install --save tick-stream
tick-stream is a Transform stream
that logs a message to show progress and passes the received data to the next
stream without applying any change to it.
By default the log message will count the number of chunks processed (ticks) usingconsole.log.
You can provide your own custom logging function with the logFunction option:
`javascript
const TickStream = require('tick-stream')
const tick = new TickStream({
logFunction: (chunk, encoding, tick) => {
console.log(I am processing chunk #${tick}, chunk)`
}
})
In case you are working with object streams you will need to initialize your tick-stream
instance in :
`javascript
const TickStream = require('tick-stream')
const tick = new TickStream({ objectMode: true })
``
