+# first-chunk-stream [![Build Status](https://travis-ci.org/sindresorhus/first-chunk-stream.svg?branch=master)](https://travis-ci.org/sindresorhus/first-chunk-stream)
+
+> Transform the first chunk in a stream
+
+Useful if you want to do something to the first chunk.
+
+You can also set the minimum size of that chunk.
+
+
+## Install
+
+```sh
+$ npm install --save first-chunk-stream
+```
+
+
+## Usage
+
+```js
+var fs = require('fs');
+var concat = require('concat-stream');
+var firstChunk = require('first-chunk-stream');
+
+// unicorn.txt => unicorn rainbow
+// `highWaterMark: 1` means it will only read 1 byte at the time
+fs.createReadStream('unicorn.txt', {highWaterMark: 1})
+	.pipe(firstChunk({minSize: 7}, function (chunk, enc, cb) {
+		this.push(chunk.toUpperCase());
+		cb();
+	}))
+	.pipe(concat(function (data) {
+		console.log(data);
+		//=> UNICORN rainbow
+	}));
+```
+
+
+## API
+
+### firstChunk([options], transform)
+
+#### options.minSize
+
+Type: `number`
+
+The minimum size of the first chunk.
+
+#### transform(chunk, encoding, callback)
+
+*Required*  
+Type: `function`
+
+The [function](http://nodejs.org/docs/latest/api/stream.html#stream_transform_transform_chunk_encoding_callback) that gets the first chunk.
+
+### firstChunk.ctor()
+
+Instead of returning a [stream.Transform](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_transform_1) instance, `firstChunk.ctor()` returns a constructor for a custom Transform. This is useful when you want to use the same transform logic in multiple instances.
