1# Determine the Encoding of a HTML Byte Stream2 3This package implements the HTML Standard's [encoding sniffing algorithm](https://html.spec.whatwg.org/multipage/syntax.html#encoding-sniffing-algorithm) in all its glory. The most interesting part of this is how it pre-scans the first 1024 bytes in order to search for certain `<meta charset>`-related patterns.4 5```js6const htmlEncodingSniffer = require("html-encoding-sniffer");7const fs = require("fs");8 9const htmlBytes = fs.readFileSync("./html-page.html");10const sniffedEncoding = htmlEncodingSniffer(htmlBytes);11```12 13The passed bytes are given as a `Uint8Array`; the Node.js `Buffer` subclass of `Uint8Array` will also work, as shown above.14 15The returned value will be a canonical [encoding name](https://encoding.spec.whatwg.org/#names-and-labels) (not a label). You might then combine this with the [whatwg-encoding](https://github.com/jsdom/whatwg-encoding) package to decode the result:16 17```js18const whatwgEncoding = require("whatwg-encoding");19const htmlString = whatwgEncoding.decode(htmlBytes, sniffedEncoding);20```21 22## Options23 24You can pass two potential options to `htmlEncodingSniffer`:25 26```js27const sniffedEncoding = htmlEncodingSniffer(htmlBytes, {28  transportLayerEncodingLabel,29  defaultEncoding30});31```32 33These represent two possible inputs into the [encoding sniffing algorithm](https://html.spec.whatwg.org/multipage/syntax.html#encoding-sniffing-algorithm):34 35- `transportLayerEncodingLabel` is an encoding label that is obtained from the "transport layer" (probably a HTTP `Content-Type` header), which overrides everything but a BOM.36- `defaultEncoding` is the ultimate fallback encoding used if no valid encoding is supplied by the transport layer, and no encoding is sniffed from the bytes. It defaults to `"windows-1252"`, as recommended by the algorithm's table of suggested defaults for "All other locales" (including the `en` locale).37 38## Credits39 40This package was originally based on the excellent work of [@nicolashenry](https://github.com/nicolashenry), [in jsdom](https://github.com/tmpvar/jsdom/blob/16fd85618f2705d181232f6552125872a37164bc/lib/jsdom/living/helpers/encoding.js). It has since been pulled out into this separate package.41
