A Minipass stream that collects all the data into a single chunk
Note that this buffers ALL data written to it, so it's only good for situations where you are sure the entire stream fits in memory.
Note: this is primarily useful for the Collect.PassThrough
class, since Minipass streams already have a .collect()
method which returns a promise that resolves to the array of chunks, and a .concat()
method that returns the data concatenated into a single Buffer or String.
const Collect = require('minipass-collect') const collector = new Collect() collector.on('data', allTheData => { console.log('all the data!', allTheData) }) someSourceOfData.pipe(collector) // note that you can also simply do: someSourceOfData.pipe(new Minipass()).concat().then(data => ...) // or even, if someSourceOfData is a Minipass: someSourceOfData.concat().then(data => ...) // but you might prefer to have it stream-shaped rather than // Promise-shaped in some scenarios.
If you want to collect the data, but also act as a passthrough stream, then use Collect.PassThrough
instead (for example to memoize streaming responses), and listen on the collect
event.
const Collect = require('minipass-collect') const collector = new Collect.PassThrough() collector.on('collect', allTheData => { console.log('all the data!', allTheData) }) someSourceOfData.pipe(collector).pipe(someOtherStream)
All minipass options are supported.
