serialportjs

Serial port library for node using pure JS (almost). It has no dependencies and has no native components. This is why buildutils is not required during npm install.

Usage

const com = new SerialPort('/dev/ttyS1');
await com.config({
    baudRate: 38400,
    databits: 8,
    stopbits: 1,
    parity: "none"
});
await com.open();
// eventStream is a readable stream. It can be piped or just:
com.eventStream.on('data', data => {
    // data is a Buffer instance
});
com.write(Buffer.from([1, 2, 3, 4]));

Linux implementation

In Linux and MacOS this library uses standard I/O operations to read/write serial ports, and calls stty command to set configuration

Windows implementation

In Windows, the library uses the serialpipe binary which must be installed and put in the path separately It can be found here: https://gitlab.com/ttopalov/serialpipe
