@polka/send-type [![npm](https://img.shields.io/npm/v/@polka/send-type.svg)](https://npmjs.org/package/@polka/send-type)\n\n> An HTTP response helper that detects `Content-Type`s & handles them accordingly — _not_ limited to [Polka][polka]!\n\nFor a simpler, bare-bones alternative, check out [`@polka/send`][send] instead~\n\n\n## Install\n\n```\n$ npm install --save @polka/send-type\n```\n\n\n## Usage\n\n```js\nconst { createReadStream } = require('fs');\nconst send = require('@polka/send-type');\n\nmodule.exports = function (req, res) {\n if (!req.getHeader('authorization')) {\n // Objects are converted to JSON\n return send(res, 401, { error:'Token required!' });\n }\n // Streams & Buffers are auto-piped\n // Your 'Content-Type' is always used,\n // ~> otherwise 'application/octet-stream'\n let file = createReadStream('massive.mp4');\n send(res, 206, file, { 'Content-Type': 'video/mp4' });\n}\n```\n\n\n## API\n\n### send(res, code, data, headers)\n\n#### res\nType: `ServerReponse`\n\nThe outgoing HTTP response.\n\n#### code\nType: `Number`
\nDefault: `200`\n\nThe `statusCode` for your response.\n\n#### data\nType: `String`
\nDefault: `''`\n\nThe `body` for your response. Defaults to the `statusText` for the given `statusCode`.\n\nSee [Data Detections](#data-detections) for special behaviors.\n\n#### headers\nType: `Object`
\nDefault: `{}`\n\nThe `headers` for your response.\n\nThe `Content-Type` header is a little unique – it will be set with the value you provide in `headers`. However, if you _did not_ set a value explicitly, then `send-type` will reuse the existing value via [`res.getHeader`](https://nodejs.org/api/http.html#http_response_getheader_name).
If neither existed, then the `Content-Type` will be inferred by the data type.\n\nSee [Data Detections](#data-detections) for special behaviors.\n\n\n## Data Detections\n\nThe following operations will be performed for the following data types:\n\n> **Important:** If this is too much magic for you, check out [`@polka/send`][send] instead!\n\n### Buffers\n- Sets `Content-Type` to `'application/octet-stream'`, unless one exists in [`headers`](#headers)\n- Sets `Content-Length`\n\n### Objects\n- Casts [`data`](#data) to string via `JSON.stringify`\n- Sets `Content-Type` to `'application/json; charset=utf-8'`, unless one exists in [`headers`](#headers)\n- Sets `Content-Length`\n\n### Streams\n- Sets `Content-Type` to `'application/octet-stream'`, unless one exists in [`headers`](#headers)\n- Pipes [`data`](#data) into the [`res`](#res) directly\n\n\n## Support\n\nAny issues or questions can be sent to the [Polka][polka] repo, but please specify that you are using `@polka/send-type`.\n\n\n## License\n\nMIT © [Luke Edwards](https://lukeed.com)\n\n[polka]: https://github.com/lukeed/polka\n[send]: https://github.com/lukeed/polka/tree/master/packages/send\n","maintainers":[{"name":"lukeed","email":"luke@lukeed.com"}],"time":{"modified":"2022-06-12T22:43:32.332Z","created":"2018-01-23T22:04:55.011Z","0.3.0":"2018-01-23T22:04:55.011Z","0.3.1":"2018-02-03T04:24:46.590Z","0.3.2":"2018-02-07T02:02:51.857Z","0.3.3":"2018-02-09T19:08:51.821Z","0.3.4":"2018-02-16T22:18:40.687Z","0.4.0":"2018-05-14T19:43:12.790Z","0.5.0":"2018-09-18T18:17:32.480Z","0.5.2":"2019-02-08T23:09:28.773Z"},"repository":{"type":"git","url":"https://github.com/lukeed/polka.git"},"author":{"name":"Luke Edwards","email":"luke@lukeed.com","url":"https://lukeed.com"},"license":"MIT","readmeFilename":"readme.md"}
