| HTTP Range processing utilities. | ||
| #### HTTP Range processing utilities. | ||
| [](http://travis-ci.org/hapijs/ammo) | ||
| **ammo** is part of the **hapi** ecosystem and was designed to work seamlessly with the [hapi web framework](https://hapi.dev) and its other components (but works great on its own or with other frameworks). If you are using a different web framework and find this module useful, check out [hapi](https://hapi.dev) – they work even better together. | ||
| ## Usage | ||
| ### Visit the [hapi.dev](https://hapi.dev) Developer Portal for tutorials, documentation, and support | ||
| ```js | ||
| // basic usage | ||
| const range = Ammo.header('bytes=1-5', 10); | ||
| // range --> [{ from: 1, to: 5 }] | ||
| ## Useful resources | ||
| // multiple ranges | ||
| const range = Ammo.header('bytes=1-5,7-10', 10); | ||
| // range --> [{ from: 1, to: 5 }, { from: 7, to: 9 }] | ||
| // streams (get range within a `source`) | ||
| const range = Ammo.header('bytes=1000-4000', 5000); | ||
| const stream = new Ammo.Stream(range[0]); | ||
| const buffer = await Wreck.read(source.pipe(stream)); | ||
| // buffer is the portion of source within range | ||
| ``` | ||
| ## API | ||
| ### `header(header, length)` | ||
| Parses the range from a HTTP header. | ||
| * `header` - A string in the form of `bytes=from-to`, where `from` and `to` are | ||
| integers specifying the range. Both are optional. Multiple ranges can be passed | ||
| as a comma delimited list. | ||
| * `length` - A positive integer specifying the maximum length the range can | ||
| cover. If a `to` value passed in the `header` string is greater than `length`, | ||
| the `to` value is set as `length - 1`. | ||
| Returns an array of objects with the properties `from` and `to`, which specify | ||
| the beginning and ending of the range. Overlapping ranges are combined into one | ||
| object. Returns `null` for invalid input. | ||
| ### `new Ammo.Stream(range)` | ||
| Creates a [`Transform Stream`](https://nodejs.org/api/stream.html) that extracts | ||
| the portion of a piped in stream within `range`. | ||
| * `range` - an object with the properties `from` and `to` that specify the range | ||
| of the piped in stream to read. Objects returned by `Ammo.header` can be passed | ||
| into `range`. | ||
