Req Range

Range header parser.

The size parameter is the maximum size of the resource.

The options parameter is an object that can have the following properties.

| Property | Type | Description | |-------------|-------------------------------------------------------------------------| | combine | Boolean | Specify 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.|

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

// parse header from request
const range = req.range(1000)

// the type of the range
if (range.type === 'bytes') {
  // the ranges
  range.forEach((r) => {
    // do something with r.start and r.end
  })
}
