  "readme": "# first-chunk-stream [![Build Status](https://travis-ci.org/sindresorhus/first-chunk-stream.svg?branch=master)](https://travis-ci.org/sindresorhus/first-chunk-stream)\n\n> Transform the first chunk in a stream\n\nUseful if you want to do something to the first chunk.\n\nYou can also set the minimum size of that chunk.\n\n\n## Install\n\n```sh\n$ npm install --save first-chunk-stream\n```\n\n\n## Usage\n\n```js\nvar fs = require('fs');\nvar concat = require('concat-stream');\nvar firstChunk = require('first-chunk-stream');\n\n// unicorn.txt => unicorn rainbow\n// `highWaterMark: 1` means it will only read 1 byte at the time\nfs.createReadStream('unicorn.txt', {highWaterMark: 1})\n\t.pipe(firstChunk({minSize: 7}, function (chunk, enc, cb) {\n\t\tthis.push(chunk.toUpperCase());\n\t\tcb();\n\t}))\n\t.pipe(concat(function (data) {\n\t\tconsole.log(data);\n\t\t//=> UNICORN rainbow\n\t}));\n```\n\n\n## API\n\n### firstChunk([options], transform)\n\n#### options.minSize\n\nType: `number`\n\nThe minimum size of the first chunk.\n\n#### transform(chunk, encoding, callback)\n\n*Required*  \nType: `function`\n\nThe [function](http://nodejs.org/docs/latest/api/stream.html#stream_transform_transform_chunk_encoding_callback) that gets the first chunk.\n\n### firstChunk.ctor()\n\nInstead 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.\n\n\n## License\n\nMIT © [Sindre Sorhus](http://sindresorhus.com)\n",
