Introduction

Welcome to fetchquack 🦆 — a lightweight, universal HTTP client built on the standard Fetch API.

What is fetchquack?

fetchquack is a modern HTTP client library designed for developers who need powerful features without the bloat. It’s built on top of the standard Fetch API, which means it works everywhere JavaScript runs.

Why fetchquack?

Built on Web Standards

fetchquack uses the native Fetch API under the hood, ensuring compatibility and future-proof code. No proprietary abstractions—just enhanced functionality on top of what browsers and runtimes already provide.

Universal Runtime Support

Write once, run anywhere:

• Browser — Modern browsers with full feature support
• Node.js — Version 18+ with native fetch
• Bun — Full compatibility with Bun’s optimized runtime
• Deno — Works seamlessly in Deno’s secure runtime

First-Class Streaming Support

Unlike traditional HTTP clients, fetchquack treats streaming as a first-class citizen:

• Stream text and binary responses
• Server-Sent Events (SSE) with auto-reconnect
• Progress tracking for uploads and downloads
• Cancellation via AbortController

Zero Dependencies

fetchquack has zero runtime dependencies. The core library is just ~4KB minified and gzipped, making it perfect for bundle-size-conscious applications.
