@routup/query

Parses the request URL's query string once per request and caches it on event.store. Supports nested keys (foo[bar]=1), repeated keys (tag=a&tag=b), and the standard URLSearchParams decoding.

Installation

npm install @routup/query

Quick start

import { App, defineCoreHandler, serve } from 'routup';
import { query, useRequestQuery } from '@routup/query';

const router = new App();

router.use(query());

router.get('/', defineCoreHandler((event) => {
    const q = useRequestQuery(event);
    return q;
}));

serve(router, { port: 3000 });

GET /?foo=bar&tag=a&tag=b resolves to { foo: 'bar', tag: ['a', 'b'] }.

When to use it

• Reading ?page=2&pageSize=20 style filters
• Parsing nested query syntax that URLSearchParams alone doesn't reify
• Any handler that needs query parameters multiple times — the parse runs once

If you only need a single value once per request, event.searchParams.get('foo') from the core works without the plugin. The plugin pays for itself when you need the parsed object, nested keys, or caching.

Companion plugins

• @routup/basic bundles query + body + cookie.
• @routup/decorators wires the helpers to @DQuery().
