npm run build:lib

Expanding the ESLint configuration

If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:

export default tseslint.config({
  extends: [
    // Remove ...tseslint.configs.recommended and replace with this
    ...tseslint.configs.recommendedTypeChecked,
    // Alternatively, use this for stricter rules
    ...tseslint.configs.strictTypeChecked,
    // Optionally, add this for stylistic rules
    ...tseslint.configs.stylisticTypeChecked,
  ],
  languageOptions: {
    // other options...
    parserOptions: {
      project: ["./tsconfig.node.json", "./tsconfig.app.json"],
      tsconfigRootDir: import.meta.dirname,
    },
  },
});

You can also install eslint-plugin-react-x and eslint-plugin-react-dom for React-specific lint rules:

// eslint.config.js
import reactX from "eslint-plugin-react-x";
import reactDom from "eslint-plugin-react-dom";

export default tseslint.config({
  plugins: {
    // Add the react-x and react-dom plugins
    "react-x": reactX,
    "react-dom": reactDom,
  },
  rules: {
    // other rules...
    // Enable its recommended typescript rules
    ...reactX.configs["recommended-typescript"].rules,
    ...reactDom.configs.recommended.rules,
  },
});
