Hi, @bobbeck55. We do already have linting in our frontend workflow (https://github.com/sillsdev/TheCombine/blob/master/.github/workflows/frontend.yml#L39)

      - run: npm run lint

which runs ESLint (https://github.com/sillsdev/TheCombine/blob/master/package.json#L24)

    "lint": "           eslint --max-warnings=0 --ext js,ts,tsx,jsx src",
