read data from serial port using angular2

[Jitendra Rajauriya]

We want to serial port communication using existing angular2 project.

I installed the following.

npm install serialport --save
npm install @types/serialport --save

and

import { SerialPort } from 'serialport' in component.ts
serialPort: typeof SerialPort;

now we got undefined from serialPort.
and got the Can't resolve 'child_process' node_modules\@serialport\bindings\lib error for get port.
any one can help.

Hi Jitendra,

Is the serialPort module suited for use in a browser? A lot of NPM modules only work in a server setting!

we are using https://github.com/garrows/browser-serialport for serial communication in client side.

when we using following after import in angular component

SerialPort.list(function(err, ports) {
            console.log(err);
            console.log(ports);
        });

we got Error: No access to serial ports. Try loading as a Chrome Application.

any suggestions?

Yes, that is a constraint Google did put in Chrome. Clearly documented in that repo.

There is also web-serial in the pipeline. That will be available in Chrome 77 behind a flag.  It's expected to go main-stream in V80/83, (expectation, not a guarantee!)
