Mozilla&#s new Machine Learning API, BIG changes in Bun , developer tools, and more

JavaScript News Flash!

Welcome to this week’s JavaScript news!

From performance improvements in Bun 1.2 to AI-powered network extensions in Mozilla Firefox and the latest ecosystem-changing tools, we’ve got a lot to unpack.

Let’s get started!

Bun 1.2: Faster, Stronger, Better

Bun 1.2 is making headlines in the JavaScript runtime world, pushing the boundaries of Node.js compatibility with a major update. Thousands of bug fixes and performance improvements make Bun a more reliable choice in production environments. Migrating from Node.js has never been easier because Bun minimizes disruption and maintains functionality.

Main features:

• Text-based lock file: Bun converts to a text-based lock file for easier dependency management and debugging, improving project workflow clarity.
• Native support for S3 and Postgres: Developers can now enjoy seamless integration with Amazon S3 and Postgres to speed up cloud development setup.
• JSONC Support: Annotated JSON files make configuration easier to read and manage.
• Express.js 3x faster: Massive performance improvements make Express.js applications run 3x faster.

Transformers.js v3.3

Transformers.js v3.3 continues to advance the field of machine learning, delivering state-of-the-art NLP (Natural Language Processing) and TTS (Text-to-Speech) directly to your browser. No server-side processing required - everything runs smoothly on the client-side.

Outstanding Features:

• StyleTTS 2: A near-human-level text-to-speech model that runs in the browser, perfect for voice assistants or speech features.
• Grounding DINO: Zero-shot object detection that works without labeled data, ideal for real-time applications.
• React Integration: Improved integration with React makes using ML models in web applications easier than ever.
• Live Demo: Test live TTS capabilities with impressive results comparable to cloud services.

Mozilla’s ML-based web extensions

Mozilla Firefox’s Nightly browser introduces a machine learning API that enables on-device ML tasks without cloud processing. This privacy-focused approach reduces latency while keeping data secure.

What you can do with Firefox’s ML API:

• Text Abstract on the device: Summary articles and network content, no external server is required.
Target detection and image classification:
• performing target recognition and other tasks directly in the browser. Supported by the transformers.js and onnx engines:
seamless integration with these tools provides fast and secure ML operations.
• This API brings ML on the device that focuses on privacy, creating new opportunities for AI -based web applications.

The tools and versions you should understand

Let us quickly learn about the latest tools that caused a sensation in the JavaScript world this week!

RSPACK V1.2:

It improves the bundle efficiency through the long -term cache (increased the speed of 250%!), Yarn PNP support and Angular integration.

• CAPACITOR 7: Fully supports Android 15 and iOS 18, Swift Package Manager and Simplified dependencies management for cross -platform applications development.
VITEST 3.0:
• Enhanced VITE native test through multi -browser settings, line -based test screening and community -driven innovation. ARKTYPE 2.0:
Rebcing runtime verification -100 times faster than ZOD, easily connect the TypeScript bridge to JavaScript.
• React Admin 5.5: Now supports React 19, React Router 7, and MUI 6. It has batch operations, string array editing, and better cache for the front end of the B2B.
