## 📺 Preview

## ☝️ Prerequisites

- Jotai version `>=v2.20.0`
- React version `>=17.0.0`

## 📦 Setup

_(See complete setup guide for UI-based devtools below)_

```sh
# yarn
yarn add jotai-devtools

# npm
npm install jotai-devtools --save
```

## ✨ UI DevTools

Enhance your development experience with the UI based Jotai DevTool

[![Demo](https://img.shields.io/badge/demo-%F0%9F%9A%80-green?style=flat&colorA=000000&colorB=259e02)](https://codesandbox.io/s/jotai-devtools-demo-k5p12d)

### Babel plugin setup - (Optional but highly recommended)

Use Jotai babel plugins for an optimal debugging experience. Find the complete
guide on [jotai.org](https://jotai.org/docs/tools/babel)

Eg.

```ts
{
  "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](https://nextjs.org)._

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

```ts
// 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

```ts
type DevToolsProps = {
  // Defaults to false
  isInitialOpen?: boolean;
  // pass a custom store
  store?: Store;
  // Defaults to light
  theme?: 'dark' | 'light';
  // Defaults to 'bottom-left'
  position?: 'top-right' | 'top-left' | 'bottom-right' | 'bottom-left';
  // Custom nonce to allowlist jotai-devtools specific inline styles via CSP
  nonce?: string;
  // We recommend keeping these options static. i.e. set it only once. Avoid connecting it to a re-renderable state
  options?: {
    // Private atoms are used internally in atoms like `atomWithStorage` or `atomWithLocation`, etc. to manage state.
    // Defaults to `false`
    shouldShowPrivateAtoms?: boolean;
    // Expands the JSON tree view on initial render on the Atom Viewer tab, Timeline tab, etc.
    // Defaults to `false`
    shouldExpandJsonTreeViewInitially?: boolean;
    // The interval (in milliseconds) between each step of the time travel playback.
    // Defaults to `750ms`
    timeTravelPlaybackInterval?: number;
    // The maximum number of snapshots to keep in the history.
    // The higher the number the more memory it will consume.
    // Defaults to `Infinity`. Recommended: `~30`
    snapshotHistoryLimit?: number;
  };
};
```

### Provider-less

```tsx
import { DevTools } from './JotaiDevTools';
import 'jotai-devtools/styles.css';
const App = () => {
  return (
    <>
      <DevTools />
      {/* your app */}
    </>
  );
};
```

### With Provider

```tsx
import { createStore } from 'jotai';

import { DevTools } from 'jotai-devtools';
import 'jotai-devtools/styles.css';

const customStore = createStore();

const App = () => {
  return (
    <Provider store={customStore}>
      <DevTools store={customStore} />
      {/* your app */}
    </Provider>
  );
};
```

## Tree-shaking

Jotai DevTools is currently only available in development mode. We're changing
this in the future to allow it to be used in production as well.

Therefore, we recommend wrapping the DevTools in a conditional statement and
tree-shake it out in production to avoid any accidental usage in production.

### Vite

```tsx
import { DevTools } from 'jotai-devtools';
import css from 'jotai-devtools/styles.css?inline';

const JotaiDevTools = () =>
  process.env.NODE_ENV !== 'production' ? (
    <>
      <style>{css}</style>
      <DevTools />
    </>
  ) : null;

const App = () => {
  return (
    <>
      <JotaiDevTools />
      {/* your app */}
    </>
  );
};
```

### NextJS

Create a `DevTools.tsx` file in your project and export the `DevTools`
component.

```tsx
import 'jotai-devtools/styles.css';
export { DevTools } from 'jotai-devtools';
```

Then, in your app, import the `DevTools` component conditionally.

```tsx
import dynamic from "next/dynamic";
import type { ComponentType } from "react";
import type { DevToolsProps } from "jotai-devtools";

let DevTools: ComponentType<DevToolsProps> | null = null;

if (process.env.NODE_ENV !== "production") {
  DevTools = dynamic(
    () => import("./DevTools").then((mod) => ({ default: mod.DevTools })),
    { ssr: false }
  );
}

const App = () => {
  return (
    <>
      {DevTools && <DevTools />}
      {/* your app */}
    </>
  );
```

## Hooks

Detailed documentation is available on
[https://jotai.org/docs/api/devtools](https://jotai.org/docs/api/devtools)

```tsx
import {
  useAtomsSnapshot,
  useGotoAtomsSnapshot,
  useAtomsDebugValue,
  // Redux devtool hooks
  useAtomDevtools,
  useAtomsDevtools,
} from 'jotai-devtools';
```

## Migration guides

### Migrate ƒrom @emotion/react to native CSS

With the latest release, Jotai DevTools no longer depends on `@emotion/react`
and is replaced with native CSS.

1. Remove `@emotion/react` from your dependencies

```sh
   # yarn
   yarn remove @emotion/react

# npm
   npm uninstall @emotion/react
   ```

2. Replace `@emotion/react` with `jotai-devtools/styles.css` in your code

Note that this css file may get included in your production builds please import
it conditionally if you want to avoid that.

```diff
import { DevTools } from 'jotai-devtools';
+ import 'jotai-devtools/styles.css';
```

### Migrate Jotai to V2

Find the official migration guide on
[jotai.org](https://jotai.org/docs/guides/migrating-to-v2-api)

### Migrate `jotai/react/devtools` to `jotai-devtools`

1. Install this package

```sh
   # npm
   npm install jotai-devtools --save

# yarn
   yarn add jotai-devtools
   ```

2. Update imports from `jotai/react/devtools` to `jotai-devtools`
   ```diff
   import {
    useAtomsSnapshot,
    useGotoAtomsSnapshot,
    useAtomsDebugValue,
    // Redux devtool integration hooks
    useAtomDevtools,
    useAtomsDevtools,
   - } from 'jotai/react/devtools';
   + } from 'jotai-devtools';
   ```
