# minipass-collect
|
|
|
|
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.
|
|
|
|
## 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)
|
|
```
|
|
|
|
