✨ UI DevTools

Enhance your development experience with the UI based Jotai DevTool

Babel plugin setup - (Optional but highly recommended)

Use Jotai babel plugins for optimal debugging experience. Find the complete guide on jotai.org

Eg.

{
  "plugins": [
    // Enables hot reload for atoms
    "jotai/babel/plugin-react-refresh",
    // Automatically adds debug labels to the atoms
    "jotai/babel/plugin-debug-label"
  ]
}

Next JS setup

You may skip this section if you're not using Next.js.

Enable transpilePackages for the UI CSS and components to be transpiled correctly.

// next.config.ts

const nextConfig = {
  // Learn more here - https://nextjs.org/docs/advanced-features/compiler#module-transpilation
  // Required for font css to be imported correctly 👇
  transpilePackages: ['jotai-devtools'],
};

module.exports = nextConfig;

Available props

type DevToolsProps = {
  // Defaults to false
  isInitialOpen?: boolean;
  // pass a custom store
  store?: Store;
  // Defaults to light
  theme?: 'dark' | 'light';
  // Custom nonce to allowlist jotai-devtools specific inline styles via CSP
  nonce?: string;
  options?: {
    // Private atoms are used internally in atoms like `atomWithStorage` or `atomWithLocation`, etc. to manage state.
    // Defaults to `false`
    shouldShowPrivateAtoms?: boolean;
  };
};

      {/* your app */}
    </Provider>
  );
