+# get-stream [![Build Status](https://travis-ci.org/sindresorhus/get-stream.svg?branch=master)](https://travis-ci.org/sindresorhus/get-stream)
+
+> Get a stream as a string, buffer, or array
+
+
+## Install
+
+```

+```
+
+
+## Usage
+
+```js
+const fs = require('fs');
+const getStream = require('get-stream');
+const stream = fs.createReadStream('unicorn.txt');
+
+getStream(stream).then(str => {
+       console.log(str);
+       /*
+                     ,,))))))));,
+                  __)))))))))))))),
+       \|/       -\(((((''''((((((((.

+});
+```
+
+
+## API
+
+The methods returns a promise that resolves when the `end` event fires on the stream, indicating that there is no more data to be read. The stream is switched to flowing mode.
+
+### getStream(stream, [options])
+
+Get the `stream` as a string.
+
+#### options
+
+##### encoding
+
+Type: `string`<br>
+Default: `utf8`
+
+[Encoding](https://nodejs.org/api/buffer.html#buffer_buffer) of the incoming stream.
+
+##### maxBuffer
+
+Type: `number`<br>
+Default: `Infinity`
+
+Maximum length of the returned string. If it exceeds this value before the stream ends, the promise will be rejected.
+
+### getStream.buffer(stream, [options])
+
+Get the `stream` as a buffer.
+
+It honors the `maxBuffer` option as above, but it refers to byte length rather than string length.
+
+### getStream.array(stream, [options])
+
+Get the `stream` as an array of values.
+
+It honors both the `maxBuffer` and `encoding` options. The behavior changes slightly based on the encoding chosen:
+
+- When `encoding` is unset, it assumes an [object mode stream](https://nodesource.com/blog/understanding-object-streams/) and collects values emitted from `stream` unmodified. In this case `maxBuffer` refers to the number of items in the array (not the sum of their sizes).
+
+- When `encoding` is set to `buffer`, it collects an array of buffers. `maxBuffer` refers to the summed byte lengths of every buffer in the array.
+
+- When `encoding` is set to anything else, it collects an array of strings. `maxBuffer` refers to the summed character lengths of every string in the array.
+
+
+## Errors
+
+If the input stream emits an `error` event, the promise will be rejected with the error. The buffered data will be attached to the `bufferedData` property of the error.
+
+```js
+getStream(streamThatErrorsAtTheEnd('unicorn'))
+       .catch(err => {
+               console.log(err.bufferedData);
+               //=> 'unicorn'
+       });
+```
+
+
+## FAQ
+
+### How is this different from [`concat-stream`](https://github.com/maxogden/concat-stream)?
+
+This module accepts a stream instead of being one and returns a promise instead of using a callback. The API is simpler and it only supports returning a string, buffer, or array. It doesn't have a fragile type inference. You explicitly choose what you want. And it doesn't depend on the huge `readable-stream` package.
