Deduplication Middleware

Coalesce identical in-flight requests into a single fetch

Basic Usage

import { dedupe } from '@cleverbrush/client/dedupe';

const client = createClient(api, {
    middlewares: [dedupe()],
});

// These fire only ONE fetch — both callers receive the same response
const [a, b] = await Promise.all([
    client.todos.list(),
    client.todos.list(),
]);

Options

Option	Type	Default
`methods`	`string[]`	`['GET']`
`key`	`(url, init) => string`	`method + url`

Only GET requests are deduplicated by default. Mutations (POST, PUT, etc.) always go through. Provide a custom keyfunction to control what counts as a "duplicate".
