WebUSB
WebUSB is a JavaScript application programming interface (API) specification for securely providing access to USB devices from web applications.
It was published by the Web Platform Incubator Community Group. As of July 2021, it is in Draft Community status, and is supported by Chromium-based browsers.
A Universal Serial Bus, or a USB is an industry standard communication protocol used to communicate data across connectors, and cables from computers to peripheral devices and/or other computers. WebUSB is a set of API calls that enable access to these hardware devices from web pages. WebUSB is developed by the World Wide Web Consortium (W3C). The WebUSB API provides a safe, and developer familiar means of communication to edge devices from web pages. The WebUSB API integrates into existing USB libraries and shortens the development cycle for integrating new devices into the web environment by not needing to wait for browser support for these devices.
Early versions of WebUSB came out around as an alternative to Flash, Chrome Serial, and other custom approaches to connecting browsers to hardware. WebUSB aims to solve the four goals of any interface being; fast to make, cross platform, look good, accessibility.
WebUSB API's are able to bridge hardware protocols to internet protocols, enabling the creating of uniform gateways linking edge devices to a centralised networks.
The explosion in computing ability over the last few decades has led to an increase in edge devices. Devices such as lights, thermometers, HVAC, motors are increasingly integrated into centralised internet control servers. These devices have evolved from isolated and previously non-integrated development environments. Consequently, they lack the uniform and consistent communication protocol necessary to develop an immediate connectivity to a web service. The WebUSB's API framework standardises disparate protocols and is able to expose non-standard Universal Serial Bus (USB) compatible devices to the web.
The WebUSB looks to sit between the perception layer and the network layer. The main goals of software in this gateway are; Scalability, Cost and reliability. The cloud-based deployment of WebUSB libraries enables it to cover scalability, its low overhead deployment significantly lowers cost, and its continual in use development over its lifetime has enabled the framework to attain a high degree of reliability.
WebUSB has formed a cornerstone of the BIPES (Block based Integrated Platform for Embedded Systems) architecture framework. This systems architecture model aims to reduce complexity of IoT systems development by aggregating relevant software into 'Blocks' that are complete units of code and can be deployed to an edge device from a centralised cloud infrastructure. As already mentioned the role of WebUSB is critically tied to its ability to communicate to embedded software through the USB communication protocol. Once the information is inside WebUSB's JavaScript environment it can be transposed and communicated through a variety of software protocols. In this particular architecture model WebUSB bridges the gap between embedded software, and the web browser. The web browser then communicates to the cloud environment using uniform WebUSB constructed data.
