English | Русский

Request collapsing and de-duplication plugin for Hyperttp.

Features

• Deduplicates concurrent equivalent requests into one network request.
• Shares the resulting response with all waiting callers.
• Removes in-flight entries after completion or failure.
• Runs in the Core v2 PREPARE phase with no external runtime dependencies.

Installation

npm install @hyperttp/inflight
# or
bun add @hyperttp/inflight

Usage

import { HyperClient } from "hyperttp";
import { withInflight } from "@hyperttp/inflight";

const client = new HyperClient({
  plugins: [withInflight()],
});

const [first, second] = await Promise.all([
  client.get("https://api.example.com/data"),
  client.get("https://api.example.com/data"),
]);

Both callers receive the result of a single request. Configure the plugin with the options provided by InflightOptions; set enabled: false to disable it.

Core v2

The plugin uses protocol-neutral SendRequest, UniversalResponse, and RequestContext values. Request data is read from protocol-specific input and metadata.
