What is the best way for my web application to interface with a serial port?

I am working on a cloud-based web application that uses ASP Web API and Angular, both hosted on Azure. I have a requirement for my Angular app to communicate with a serial port for reading and writing data. How can I achieve this functionality?

I've come across information stating that Chrome apps have the capability to connect to USB/serial devices, but I'm still unclear on how exactly it works. Should I consider rebuilding my applications as Chrome apps? Or would it be better to create a separate app altogether? Is it possible to develop Chrome apps that can seamlessly integrate with my current web app and access the serial port directly?

Answer №1

No need to redesign your app from scratch. Simply develop a chrome app and leverage webview for your cloud application. Essentially, you will handle serial port communication within the chrome app environment and transfer the data to the webview context in your chrome app, which essentially represents the app loaded from your cloud.

Alternatively, you can build your entire application as an offline chrome app and establish communication with your cloud server through ajax or websocket protocols.

An additional option worth considering is nw.js. This platform allows you to create desktop-like applications using web technologies. In an nw.js app, you can incorporate a node.js serial module for handling serial communication.

You can also combine these approaches for a tailored solution that meets your specific requirements.

Based on my positive experience with its serial module, I recommend exploring one of the chrome app methods for seamless integration with your cloud app.
