What is @hapi/ammo?

@hapi/ammo is a utility library for HTTP payload processing, specifically designed to handle HTTP payload ranges. It is part of the hapi ecosystem and is used to parse and validate HTTP Range headers, which are often used for partial content delivery.

What are @hapi/ammo's main functionalities?

Range Parsing

This feature allows you to parse the 'Range' HTTP header and determine the byte ranges requested by the client. The `Ammo.header` function takes the range header and the total length of the resource, returning an array of ranges.

const Ammo = require('@hapi/ammo');

const rangeHeader = 'bytes=0-4,9-15';
const length = 20;
const ranges = Ammo.header(rangeHeader, length);

console.log(ranges);

Range Validation

This feature validates the parsed ranges to ensure they are within the bounds of the resource length. If the ranges are valid, it returns an array of ranges; otherwise, it returns null.

const Ammo = require('@hapi/ammo');

const rangeHeader = 'bytes=0-4,9-15';
const length = 20;
const ranges = Ammo.header(rangeHeader, length);

if (ranges) {
  console.log('Valid ranges:', ranges);
} else {
  console.log('Invalid range header');
}
