BunCurl2 🚀

BunCurl2 is a super-fast, fetch-like HTTP client for Bun! Built and maintained as a solo project, it leverages Bun’s powerful child processes combined with cURL to deliver blazing performance, advanced TLS options, and flexible caching solutions.

---

✨ Features

• Fetch-like API:
  Intuitive and familiar HTTP methods (GET, POST, etc.) with extended capabilities.
• Lightning Fast:
  Powered by Bun’s child processes and optimized cURL integration.
• HTTP/2 & HTTP/3 Support:
  Take advantage of modern protocols (requires appropriate cURL build).
• Custom TLS & Ciphers:
  Enhance security by fine-tuning TLS settings.
• Flexible Caching:
  • Default (recommended): Redis, ideal for persistent or long-lived caching.
  • Optional: Local, memory-based caching using JavaScript's Map object, suitable for short-term caching within the same process.
• Type-Safe Requests & Responses:
  Enjoy clear and maintainable TypeScript typings.

📋 Requirements

Tool	Minimum Version	Recommended Version
Bun	^1.2.0	Latest
cURL	^7.0.0	Latest

Note: For optimal performance and compatibility, always use the latest versions.
I personally use stunnel/static-curl with quictls for cURL builds.

📡 Usage

Recommended: Creating a Client Instance

This approach provides the best experience with advanced configurations and caching.

import BunCurl2, { RequestInit, ResponseInit } from 'bun-curl2';

// Create a new client with customized options and caching.
const client = new BunCurl2({
  defaultAgent: 'MyCustomAgent/1.0',
  compress: true,
  cache: {
    mode: 'redis', // Recommended caching mode
    options: { url: 'redis://localhost:6379' },
    defaultExpiration: 60, // Cache expiration in seconds
  },
  tcp: {
    fastOpen: true,
    noDelay: true,
  },
  transformRequest: opts => opts,
});

// (Optional) Initialize cache if caching is enabled.
await client.connect();

// Make a GET request with type-safe response handling:
const req: ResponseInit<Record<string, string>> = await client.get(
  'https://api.example.com/data',
  { cache: true }
);

/*
Response Details:
- status: HTTP status code
- response: Parsed response (here: Record<string, string>)
- headers: Headers instance
- Helper methods: json(), text(), arrayBuffer(), blob()
*/
console.log('Status:', req.status);
console.log('Response:', req.response);

Alternative: Direct fetch-like Usage

For simpler use cases, you can directly use a familiar fetch-like syntax:

import { fetch } from 'bun-curl2';

const req: ResponseInit<string> = await fetch<string>(
  'https://www.example.com'
);

console.log('Status:', req.status);
console.log('Response:', req.response);
