Range header field parser.
This is a Node.js module available through the
npm registry. Installation is done using the
npm install command:
sh
$ npm install range-parser
js
var parseRange = require('range-parser')
Parse the given header string where size is the maximum size of the resource.
An array of ranges will be returned or negative numbers indicating an error parsing.
-2 signals a malformed header string-1 signals an unsatisfiable range```js // parse header from request var range = parseRange(size, req.headers.range)
// the type of the range if (range.type === 'bytes') { // the ranges range.forEach(function (r) { // do something with r.start and r.end }) } ```
These properties are accepted in the options object.
Specifies if overlapping & adjacent ranges should be combined, defaults to false.
When true, ranges will be combined and returned as if they were specified that
way in the header.
js
parseRange(100, 'bytes=50-55,0-10,5-10,56-60', { combine: true })
// => [
// { start: 0, end: 10 },
// { start: 50, end: 60 }
// ]
