Janus-Gate

Browser extension builds

The extension is built from one source tree with two distribution targets:

• Normal: mesh proxy connection only
• Visa: includes the normal mesh features plus the VisaTracker integration

Build either target from extension/:

cd extension
npm run build:normal
npm run build:visa

The generated extension folders are:

extension/dist/normal
extension/dist/visa

Load the desired folder as an unpacked extension in Chrome during development, or package that folder for release. dist/ is generated and is not committed.

Shared mesh functionality lives in extension/src/shared/. VisaTracker-only files live in extension/src/visa/; the build script copies those files and adds the required permission only for the Visa target.
