At JavaScripters, we constantly spotlight tools that push the boundaries of performance, simplicity, and developer happiness—and Bun is doing just that. With the release of Bun v1.2.12, the all-in-one JavaScript toolkit takes another massive leap toward becoming the default toolchain for modern developers.
Whether you’re building SPAs, backend services, or full-stack apps—Bun empowers you to develop, test, run, and bundle JavaScript & TypeScript projects with a single tool, all while offering near full compatibility with Node.js.


🆕 What’s New in Bun v1.2.12?

🖥️  --console Flag: Terminal + Browser Debug Logs = ❤️


Frontend developers, rejoice! You can now run:

bun ./index.html --console


This streams your browser’s console.log output directly to the terminal, making real-time debugging seamless—especially for multi-browser testing and terminal-focused workflows.


🧠 Memory Optimization: Lighter & Faster


Bun’s frontend dev server now uses significantly less memory, making hot module reloading and incremental builds faster and smoother—perfect for large projects or monorepos.

🔁 Node.js Compatibility: Even Deeper


Bun continues to tighten its grip on Node.js compatibility with key improvements in:

  • timers
  • vm
  • net
  • http


If your project works on Node, it very likely works on Bun now—with even better performance.

🐞 Bugfixes: TextDecoder & Hot Reload Stability

  • Fixed TextDecoder behavior for reliable encoding/decoding
  • Improved hot reloading for consistent dev server performance


🛠 Why Bun Matters for the JavaScript Ecosystem


Bun isn’t just a runtime. It’s a bundler, a package manager, a test runner, and a runtime—all in one, written in Zig for extreme speed and efficiency.

⚙️ Feature Highlights:

  • ✅ Native support for TypeScript, JSX, and ESM
  • ⚡️ Blazing-fast cold starts & installs
  • 📦 Fully functional npm package manager (bun install)
  • 🧪 Built-in test runner (bun test)
  • 📂 Out-of-the-box bundling with zero config


Whether you’re a solo developer, part of a growing team, or contributing to open source—Bun simplifies your stack without sacrificing power.
