Development

The extension is plain HTML/CSS/JavaScript with no bundler. Node.js (>= 20) is only required for the development tooling (linting, formatting, tests and packaging).

# install dev dependencies
npm install

# run the full quality gate (lint + format check + tested coverage)
npm run check

# build a Chrome Web Store-ready zip into dist/
npm run build

Script	Description
npm run lint	Lint the source with ESLint
npm run lint:fix	Auto-fix lint issues where possible
npm run format	Format the source with Prettier
npm run format:check	Verify formatting without writing changes
npm test	Run the Jest unit tests
npm run test:coverage	Run the tests and enforce the coverage threshold
npm run check	Lint + format check + tested coverage (the CI gate)
npm run build	Produce a Web Store-ready zip in dist/

Unit tests live in tests/ and cover the pure helpers in js/functions.js, js/content.js, js/ping.js, js/context.js and js/sandbox.js; the coverage threshold is enforced by npm run test:coverage (and in CI).

See CONTRIBUTING.md for the full workflow.

Manifest version

Steem Tools ships as a Manifest V3 extension, so it installs on current versions of Chrome and Edge. Two features that MV3 restricts are handled as follows:

• the Steem-JS console evaluates user code with eval(), which MV3 forbids on extension pages, so it runs inside a dedicated sandboxed page (sandbox.html / js/sandbox.js) that communicates with the popup via postMessage, and
• the front-end switcher uses a single chrome.contextMenus.onClicked listener (MV3 dropped the per-item onclick callback), with the menus created in chrome.runtime.onInstalled.

The background logic runs as a service worker (js/background.js, which importScripts the context-menu wiring in js/context.js).
