In this tutorial we are going to learn how to get started using the WebSerial library, which offers a Serial like interface over the web.

GitHub page of the library: github.com/ayushsharma82/WebSerial
Installation instructions: github.com/ayushsharma82/WebSerial#how-to-install

Under the hood, the library uses the async HTTP web server library, which you need to install as a dependency: github.com/me-no-dev/ESPAsyncWebServer
