@yume-chan/adb-backend-webusb

Backend for @yume-chan/adb using WebUSB API.

Note

WebUSB API requires a secure context (basically means HTTPS).

Chrome will treat localhost as secure, but if you want to access a dev server running on another machine, you need to add the domain to the allowlist:

  1. Open chrome://flags/#unsafely-treat-insecure-origin-as-secure
  2. Add the protocol and domain part of your url (e.g. http://192.168.0.100:9000) to the input box
  3. Choose Enable from the dropdown menu
  4. Restart your browser
