The Serial Web Bridge provides access to your local serial ports from the browser. The bridge accesses the serial ports and acts as a local server for the web browser. Communication between this server and the browser is based on Socket.IO.
This project provides a simple example that works similar to the Arduino Serial Monitor.
Open a terminal and get the code:
git clone https://github.com/edenb/serial-web-bridge.git
cd serial-web-bridge
npm installStart the Serial Web Bridge:
npm startOpen <your working dir>\serial-web-bridge\examples\arduino-serial-monitor.html in a web browser.
The example below shows a browser controlling an ESP Easy device over the serial port.
