Compiling:
I have found arduino-cli
Uploading:
There is only avrgirl but it doesn't work in browser. What should I do?

Arduinos cannot be programmend in Nodejs. You need to write C/C++ or Assembler. – chrisl Dec 08 '19 at 15:18

@chrisl, it's not about programming (code is c-generated one) it's about calling compiler from js – caxapexac Dec 08 '19 at 15:40

1Ah, ok. But you can also upload sketches with arduino-cli. If you can use it, you can also upload sketches – chrisl Dec 08 '19 at 16:14

You can't, and that's a good thing. If the browser could let a Web site access your hardware, that would be a huge security breach. You may be able to bypass this security restriction if you can write an extension (plugin) for your browser.

Okay then I will use extension for hex code uploading. Then how can I compile it using only in-browser js? – caxapexac Dec 08 '19 at 17:15

I mean: source code -> String -> Compiler -> Hex-string -> Extension -> Uploading – caxapexac Dec 08 '19 at 17:16

@caxapexac: Building a C++ compiler in JavaScript is not a trivial task. You may try to port avr-g++ using [Emscripten](https://emscripten.org/). – Edgar Bonet Dec 08 '19 at 17:42

Seems for me a weird way to do everything in the browser. Normally in such a situation you are actually building a web service, so the compilation could be done server side by calling avr-g++ or arduino-cli through the nodejs code. Then you only would need to encapsule arduino-cli in an extention for uploading on the local computer – chrisl Dec 08 '19 at 20:37

I modify the code from js-stk500 to work from browser with web serial API. but I can't makr Arduino CLI to work in browser. Is that possible? – M lab Nov 22 '22 at 09:17
