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. ## USAGE ```js 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. ```js 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](http://npm.im/minipass) are supported.
