This repository contains a Javascript implementation of esptool, a serial flasher utility for Espressif chips. Unlike the Python-based esptool, esptool-js doesn't implement generation of binary images out of ELF files, and doesn't include companion tools similar to espefuse.py and espsecure.py.
esptool-js is based on Web Serial API and works in Google Chrome and Microsoft Edge, version 89 or later.
Visit https://espressif.github.io/esptool-js/ to see this tool in action.
npm install
npm run build
python3 -m http.server 8008
Then open http://localhost:8008 in Chrome or Edge. The npm run build step builds the bundle.js used in the example index.html.
