File System Access API: Powerful Local File Operations

Introduction

For decades, web applications were limited to reading files through a clunky <input type="file"> element and had no reliable way to save changes back to the original file. The File System Access API changes this entirely. It enables web applications to read, write, and manage files and directories directly on the user’s local file system — with user permission, of course. This opens the door to building text editors, image editors, IDEs, and productivity tools that feel native.

Web Bluetooth API: Connecting Hardware from the Browser

The Web Bluetooth API brings hardware interaction to the browser, enabling web applications to communicate with Bluetooth Low Energy (BLE) devices. This opens up IoT use cases like connecting heart rate monitors, temperature sensors, and smart lights directly from web pages.

How Web Bluetooth Works

Web Bluetooth operates over the GATT (Generic Attribute Profile) protocol, which is standard for BLE communication. In this model, the BLE device acts as a peripheral that exposes services and characteristics, while the browser acts as the central that consumes them.
