= deno-bunbridge

Access Bun-specific APIs and ecosystem from Deno.

Overview

deno-bunbridge provides Deno implementations of Bun-specific APIs, allowing code written for Bun to run on Deno, and giving Deno users access to Bun ecosystem patterns.

What This Bridges

Bun API	deno-bunbridge Equivalent	Implementation
bun:sqlite	bunbridge/sqlite	FFI to libsqlite3 or better-sqlite3
Bun.serve()	bunbridge/serve	Wraps Deno.serve()
Bun.file()	bunbridge/file	Wraps Deno file APIs
Bun.spawn()	bunbridge/spawn	Wraps Deno.Command
Bun.write()	bunbridge/write	Wraps Deno.writeFile
Bun’s Zig FFI	bunbridge/ffi	Maps to Deno.dlopen

Installation

import { Database } from "jsr:@hyperpolymath/deno-bunbridge/sqlite";
import { serve } from "jsr:@hyperpolymath/deno-bunbridge/serve";

Quick Start

// Code that looks like Bun, runs on Deno
import { Database } from "deno-bunbridge/sqlite";

const db = new Database(":memory:");
db.run("CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT)");
db.run("INSERT INTO users (name) VALUES (?)", ["Alice"]);

const users = db.query("SELECT * FROM users").all();
console.log(users);

Roadmap

• v0.1 — SQLite bridge (bun:sqlite API on Deno)

• v0.2 — File and serve bridges

• v0.3 — FFI compatibility layer

• v1.0 — Full Bun API coverage
