Encode & decode HTML & XML entities with ease & speed.

## How to…

### …install `entities`

    npm install entities

### …use `entities`

```javascript
const entities = require("entities");

//encoding
entities.escape("&"); // "&"
entities.encodeXML("&"); // "&"
entities.encodeHTML("&"); // "&"

//decoding
entities.decodeXML("asdf & ÿ ü '"); // "asdf & ÿ ü '"
entities.decodeHTML("asdf & ÿ ü '"); // "asdf & ÿ ü '"
```

## Performance

This is how `entities` compares to other libraries on a very basic benchmark
(see `scripts/benchmark.ts`, for 10,000,000 iterations):

| Library        | `decode` perf | `encode` perf | `escape` perf | Bundle size                                                                |
| -------------- | ------------- | ------------- | ------------- | -------------------------------------------------------------------------- |
| entities       | 1.418s        | 6.786s        | 2.196s        | ![npm bundle size](https://img.shields.io/bundlephobia/min/entities)       |
| html-entities  | 2.530s        | 6.829s        | 2.415s        | ![npm bundle size](https://img.shields.io/bundlephobia/min/html-entities)  |

## Acknowledgements

This libary wouldn't be possible without the work of these individuals. Thanks
to

-   [@mathiasbynens](https://github.com/mathiasbynens) for his explanations
    about character encodings, and his library `he`, which was one of the
    inspirations for `entities`
-   [@inikulin](https://github.com/inikulin) for his work on optimized tries for
    decoding HTML entities for the `parse5` project
-   [@mdevils](https://github.com/mdevils) for taking on the challenge of
    producing a quick entity library with his `html-entities` library.
    `entities` would be quite a bit slower if there wasn't any competition.
    Right now `entities` is on top, but we'll see how long that lasts!
