+
+### CRXJS
+
+If you used CRXJS's vite plugin, it's a simple refactor! The main difference between CRXJS and WXT is how the tools decide which entrypoints to build. CRXJS looks at your `manifest` (and vite config for "unlisted" entries), while WXT looks at files in the `entrypoints` directory.
+
+To migrate:
+
+1. Move all entrypoints into the `entrypoints` directory, refactoring to WXT's style (TS files have a default export).
+2. Move [entrypoint specific options out of the manifest](/guide/essentials/entrypoints#defining-manifest-options) and into the entrypoint files themselves (like content script `matches` or `run_at`).
+3. Move any other `manifest.json` options [into the `wxt.config.ts` file](/guide/essentials/config/manifest), like permissions.
+4. For simplicity, you'll probably want to [disable auto-imports](/guide/essentials/config/auto-imports#disabling-auto-imports) at first (unless you were already using them via `unimport` or `unplugin-auto-imports`). If you like the feature, you can enable it later once you've finished the migration.
+5. Update your `package.json` to include all of [WXT's suggested scripts (see step 4)](/guide/installation#from-scratch)
+6. Specifically, make sure you add the `"postinstall": "wxt prepare"` script to your `package.json`.
+7. Delete your `vite.config.ts` file. Move any plugins into the `wxt.config.ts` file. If you use a frontend framework, [install the relevant WXT module](/guide/essentials/frontend-frameworks).
+8. Update your typescript project. [Extend WXT's generated config](/guide/essentials/config/typescript), and [add any path aliases to your `wxt.config.ts` file](/guide/essentials/config/typescript#tsconfig-paths).
+9. ⚠️ Compare the old production manifest to `.output/*/manifest.json`. They should have the same content as before. If not, tweak your entrypoints and config until they are the same.

+# WXT Analytics
+
+Report analytics events from your web extension extension.
+
+## Supported Analytics Providers
+
+- [Google Analytics 4 (Measurement Protocol)](#google-analytics-4-measurement-protocol)
+- [Umami](#umami)
+
+## Install With WXT
+
+1. Install the NPM package:
+   ```bash
+   pnpm i @wxt-dev/analytics
+   ```
+2. In your `wxt.config.ts`, add the WXT module:
+   ```ts
+   export default defineConfig({
+     modules: ['@wxt-dev/analytics/module'],
+   });
+   ```
+3. In your `<srcDir>/app.config.ts`, add a provider:
+
+   ```ts
+   // <srcDir>/app.config.ts
+   import { umami } from '@wxt-dev/analytics/providers/umami';
+
+   export default defineAppConfig({
+     analytics: {
+       debug: true,
+       providers: [
+         // ...
+       ],
+     },
+   });
+   ```
+
+4. Then use the `#analytics` module to report events:
+
+   ```ts
+   import { analytics } from '#analytics';
+
+   await analytics.track('some-event');
+   await analytics.page();
+   await analytics.identify('some-user-id');
+   analytics.autoTrack(document.body);
+   ```
+
+## Install Without WXT
+
+1. Install the NPM package:
+   ```bash
+   pnpm i @wxt-dev/analytics
+   ```
+2. Create an `analytics` instance:
+
+   ```ts
+   // utils/analytics.ts
+   import { createAnalytics } from '@wxt-dev/analytics';
+
+   export const analytics = createAnalytics({
+     providers: [
+       // ...
+     ],
+   });
+   ```
+
+3. Import your analytics module in the background to initialize the message listener:
+   ```ts
+   // background.ts
+   import './utils/analytics';
+   ```
+4. Then use your `analytics` instance to report events:
+
+   ```ts
+   import { analytics } from './utils/analytics';
+
+   await analytics.track('some-event');
+   await analytics.page();
+   await analytics.identify('some-user-id');
+   analytics.autoTrack(document.body);
+   ```
+
+## Providers
+
+### Google Analytics 4 (Measurement Protocol)
+
+The [Measurement Protocol](https://developers.google.com/analytics/devguides/collection/protocol/ga4) is an alternative to GTag for reporting events to Google Analytics for MV3 extensions.
+
+> [Why use the Measurement Protocol instead of GTag?](https://developer.chrome.com/docs/extensions/how-to/integrate/google-analytics-4#measurement-protocol)
+
+Follow [Google's documentation](https://developer.chrome.com/docs/extensions/how-to/integrate/google-analytics-4#setup-credentials) to obtain your credentials and put them in your `.env` file:
+
+```dotenv
+WXT_GA_API_SECRET='...'
+```
+
+Then add the `googleAnalytics4` provider to your `<srcDir>/app.config.ts` file:
+
+```ts
+import { googleAnalytics4 } from '@wxt-dev/analytics/providers/google-analytics-4';
+
+export default defineAppConfig({
+  analytics: {
+    providers: [
+      googleAnalytics4({
+        apiSecret: import.meta.env.WXT_GA_API_SECRET,
+        measurementId: '...',
+      }),
+    ],
+  },
+});
+```
+
+### Umami
+
+[Umami](https://umami.is/) is a privacy-first, open source analytics platform.
+
+In Umami's dashboard, create a new website. The website's name and domain can be anything. Obviously, an extension doesn't have a domain, so make one up if you don't have one.
+
+After the website has been created, save the website ID and domain to your `.env` file:
+
+```dotenv
+WXT_UMAMI_WEBSITE_ID='...'
+WXT_UMAMI_DOMAIN='...'
+```
+
+Then add the `umami` provider to your `<srcDir>/app.config.ts` file:
+
+```ts
+import { umami } from '@wxt-dev/analytics/providers/umami';
+
+export default defineAppConfig({
+  analytics: {
+    providers: [
+      umami({
+        apiUrl: 'https://<your-umami-instance>/api',
+        websiteId: import.meta.env.WXT_UMAMI_WEBSITE_ID,
+        domain: import.meta.env.WXT_UMAMI_DOMAIN,
+      }),
+    ],
+  },
+});
+```
+
+### Custom Provider
+
+If your analytics platform is not supported, you can provide an implementation of the `AnalyticsProvider` type in your `app.config.ts` instead:
+
+```ts
+import { defineAnalyticsProvider } from '@wxt-dev/analytics/client';
+
+interface CustomAnalyticsOptions {
+  // ...
+}
+
+const customAnalytics = defineAnalyticsProvider<CustomAnalyticsOptions>(
+  (analytics, analyticsConfig, providerOptions) => {
+    // ...
+  },
+);
+
+export default defineAppConfig({
+  analytics: {
+    providers: [
+      customAnalytics({
+        // ...
+      }),
+    ],
+  },
+});
+```
+
+Example `AnalyticsProvider` implementations can be found at [`./modules/analytics/providers`](https://github.com/wxt-dev/wxt/tree/main/packages/analytics/modules/analytics/providers).
+
+## User Properties
+
+User ID and properties are stored in `browser.storage.local`. To change this or customize where these values are stored, use the `userId` and `userProperties` config:
+
+```ts
+// app.config.ts
+import { storage } from 'wxt/storage';
+
+export default defineAppConfig({
+  analytics: {
+    userId: storage.defineItem('local:custom-user-id-key'),
+    userProperties: storage.defineItem('local:custom-user-properties-key'),
+  },
+});
+```
+
+To set the values at runtime, use the `identify` function:
+
+```ts
+await analytics.identify(userId, userProperties);
+```
+
+Alternatively, a common pattern is to use a random string as the user ID. This keeps the actual user information private, while still providing useful metrics in your analytics platform. This can be done very easily using WXT's storage API:
+
+```ts
+// app.config.ts
+import { storage } from 'wxt/storage';
+
+export default defineAppConfig({
+  analytics: {
+    userId: storage.defineItem('local:custom-user-id-key', {
+      init: () => crypto.randomUUID(),
+    }),
+  },
+});
+```
+
+If you aren't using `wxt` or `@wxt-dev/storage`, you can define custom implementations for the `userId` and `userProperties` config:
+
+```ts
+const analytics = createAnalytics({
+  userId: {
+    getValue: () => ...,
+    setValue: (userId) => ...,
+  }
+})
+```
+
+## Auto-track UI events
+
+Call `analytics.autoTrack(container)` to automatically track UI events so you don't have to manually add them. Currently it:
+
+- Tracks clicks to elements inside the `container`
+
+In your extension's HTML pages, you'll want to call it with `document`:
+
+```ts
+analytics.autoTrack(document);
+```
+
+But in content scripts, you usually only care about interactions with your own UI:
+
+```ts
+const ui = createIntegratedUi({
+  // ...
+  onMount(container) {
+    analytics.autoTrack(container);
+  },
+});
+ui.mount();
+```
+
+## Enabling/Disabling
+
+By default, **analytics is disabled**. You can configure how the value is stored (and change the default value) via the `enabled` config:
+
+```ts
+// app.config.ts
+import { storage } from 'wxt/storage';
+
+export default defineAppConfig({
+  analytics: {
+    enabled: storage.defineItem('local:analytics-enabled', {
+      fallback: true,
+    }),
+  },
+});
+```
+
+At runtime, you can call `setEnabled` to change the value:
+
+```ts
+analytics.setEnabled(true);
+```
