File System Access API: Powerful Local File Operations

Sat, 28 Dec 2024 00:00:00 +0900

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 블루투스 API brings hardware interaction to the browser, enabling web applications to communicate with 블루투스 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 블루투스 Works

Web 블루투스 operates over the GATT (Generic Attribute 프로필) 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.
