Bump @mjackson/headers from 0.9.0 to 0.10.0

[dependabot]

Bumps @mjackson/headers from 0.9.0 to 0.10.0.

Release notes

Sourced from @​mjackson/headers's releases.

headers v0.10.0

This release contains several improvements to Cookie that bring it more in line with other headers like Accept, AcceptEncoding, and AcceptLanguage.

• BREAKING CHANGE: cookie.names() and cookie.values() are now getters that return string[] instead of methods that return IterableIterator<string>
• BREAKING CHANGE: cookie.forEach() calls its callback with (name, value, cookie) instead of (value, name, map)
• BREAKING CHANGE: cookie.delete(name) returns void instead of boolean

// before
let cookieNames = Array.from(headers.cookie.names());
// after
let cookieNames = headers.cookie.names;

Additionally, this release adds support for the If-None-Match header. This is useful for conditional GET requests where you want to return a response with content only if the ETag has changed.

import { SuperHeaders } from '@mjackson/headers';
function requestHandler(request: Request): Promise<Response> {
let response = await callDownstreamService(request);
if (request.method === 'GET' && response.headers.has('ETag')) {
let headers = new SuperHeaders(request.headers);
if (headers.ifNoneMatch.matches(response.headers.get('ETag'))) {
return new Response(null, { status: 304 });
}
}
return response;
}
