Grantzy Extension

Chrome/Chromium Manifest V3 extension that powers the Grantzy side panel flow: search applications, inspect values, and assist form filling on the active tab.

Development Commands

• npm run build: build side panel bundle
• npm run lint: static lint checks on src/ and tests
• npm run test: unit tests for pure modules
• npm run check: lint + tests

Permissions Rationale

The manifest keeps only permissions currently used at runtime.

• storage: persist selected application data, recent history, and extension token/settings.
• sidePanel: open and control the extension side panel.
• scripting: inject formFiller.content.js into the active tab before analyze/fill actions.
• tabs: read active tab metadata (URL/origin) for permission checks and autofill operations.

Host permissions:

• Required host permissions:
  • https://grantzy.com/*
  • http://localhost/*
  • http://127.0.0.1/*
• Optional runtime-granted host permissions:
  • http://*/*
  • https://*/*

The optional host permissions are requested only when the user triggers autofill on a site that is not already covered by required host permissions.
