+
+Each directory inside `templates/` is it's own standalone project. Simply `cd` into the directory you're updating, install dependencies with `npm` (NOT `pnpm`), and run the relevant commands
+
+```sh
+cd templates/vue
+npm i
+npm run dev
+npm run build
+```
+
+Note that templates are hardcoded to a specific version of `wxt` from NPM, they do not use the local version. PR checks will test your changes against the templates, but if you want to manually do it, update the package.json dependency:
+
+```diff
+  "devDependencies": {
+    "typescript": "^5.3.2",
+    "vite-plugin-solid": "^2.7.0",
+-   "wxt": "^0.8.0"
++   "wxt": "../.."
+  }
+```
+
+Then run `npm i` again.
+
+### Adding Templates
+
+To add a template, copy the vanilla template and give it a new name.
+
+```sh
+cp -r templates/vailla templates/<new-template-name>
+```
+
+That's it. Once your template is merged, it will be available inside `wxt init` immediately. You don't need to release a new version of WXT to release a new template.

-# Build Targets
-
-You can build an extension for any combination of browser and manifest verison. Different browsers and manifest versions support different APIs and entrypoints, so be sure to check that your extension functions as expected for each target.
-
-Separate build targets are written to their own output directories:
-
-```
-<rootDir>
-└─ .output
-   ├─ chrome-mv3
-   ├─ firefox-mv2
-   ├─ edge-mv3
-   └─ ...
-```
-
-## Target Browser
-
-To build for a specific browser, pass the `-b --browser` flag from the CLI:
-
-```
-
-wxt --browser firefox
-wxt build --browser firefox
-
-```
-
-By default, it will build for `chrome`. When excluding the [`--mv2` or `--mv3` flags](#target-manifest-version), it will default to the commonly accepted manifest version used with that browser.
-
-| Browser          | Default Manifest Version |
-| ---------------- | :----------------------: |
-| `chrome`         |            3             |
-| `firefox`        |            2             |
-| `safari`         |            2             |
-| `edge`           |            3             |
-| Any other string |            3             |
-
-## Target Manifest Version
-
-To build for a specific manifest version, pass either the `--mv2` flag or `--mv3` flag from the CLI.
-
-```sh
-wxt --mv2
-wxt build --mv2
-```
-
-When the `-b --browser` flag is not passed, it defaults to `chrome`. So here, we're targetting MV2 for Chrome.

-# Defining Entrypoints
-
-An "entrypoint" is any HTML, JS, or CSS file that needs to be bundled and included with the extension.
-
-Entrypoints may or may not be listed in the extension's `manifest.json`.
-
-## `/entrypoints` Directory
-
-In WXT, entrypoints are defined by adding a file to the `entrypoints/` directory.
-
-For example, a project that looks like this:
-
-```
-<rootDir>
-└─ entrypoints/
-   ├─ background.ts
-   ├─ content.ts
-   ├─ injected.ts
-   └─ popup.html
-```
-
-would result in the following `manifest.json`:
-
-```json
-{
-  // ...
-  "manifest_version": 3,
-  "action": {
-    // ...
-    "default_popup": "popup.html"
-  },
-  "background": {
-    // ...
-    "service_worker": "background.js"
-  },
-  "content_scripts": [
-    {
-      // ...
-      "js": ["content-scripts/content.js"]
-    }
-  ]
-}
-```
-
-If a file uses a [special name recognized by WXT](/get-started/entrypoints.md), it will be added to the manifest. In this case:
-
-- `popup.html` &rarr; `action.default_popup`
-- `content.ts` &rarr; `content_scripts.0.js.0`
-- `background.ts` &rarr; `background.service_worker`
-
-But not all entrypoints are added to the `manifest.json`. If the filename is not recognized by WXT, they are still built and included in the extension, but they are considered "unlisted" and are not apart of the manifest.
-
-In this case, `injected.ts` gets output to `<outdir>/injected.js` and is accessible via `browser.runtime.getURL("/injected.js")`.
-
-:::info
-See [`/entrypoints` folder](/guide/background.md) documentation for a full list of recognized entrypoint filenames.
-:::
-
-## Entrypoint Options
-
-Some entrypoints, like content scripts, actions, or the background, can recieve additional options.
-
-In HTML files, options are listed as `meta` tags:
-
-```html
-<html>
-  <head>
-    <!-- Defining the popup's "default_icon" field -->
-    <meta name="manifest.default_icon" content="{ '16': '/icon/16.png' }" />
-  </head>
-</html>
-```
-
-In TS files, options are apart of the file's default export:
-
-```ts
-export default defineContentScript({
-  matches: ['*://*.google.com/*'],
-  runAt: 'document_start',
-  main() {
-    // ...

+
+See the [API Reference](/api/wxt/client/functions/createIntegratedUi) for the complete list of options.
+
+You can control how CSS is injected for an integrated content script UI with the [`cssInjectionMode`](/api/wxt/interfaces/ContentScriptBaseDefinition#cssinjectionmode) property. Usually, you'll want to leave it as `"manifest"`, the default, so the UI inherits its style from the website's CSS.
+
+## Shadow Root
+
+Often in web extensions, you don't want your content script's CSS affecting the page, or vise-versa. The [`ShadowRoot`](https://developer.mozilla.org/en-US/docs/Web/API/ShadowRoot) API is ideal for this.
+
+WXT's [`createShadowRootUi`](/api/wxt/client/functions/createShadowRootUi) abstracts all the `ShadowRoot` setup away, making it easy to create UIs with isolated CSS. It also supports an optional `isolateEvents` parameter to further isolate user interactions.
+
+To use `createShadowRootUi`, follow these steps:
+
+1. Import your CSS file at the top of your content script
+2. Set [`cssInjectionMode: "ui"`](/api/wxt/interfaces/ContentScriptBaseDefinition#cssinjectionmode) inside `defineContentScript`
+3. Define your UI with `createShadowRootUi()`
+4. Mount the UI so it is visible to users

+
+## IFrame
+
+If you don't need to run your UI in the same frame as the content script, you can use an IFrame to host your UI instead. Since an IFrame just hosts an HTML page, **_HMR is supported_**.
+
+WXT provides a helper function, [`createIframeUi`](/api/wxt/client/functions/createIframeUi), which simplifies setting up the IFrame.
+
+1. Create an HTML page that will be loaded into your IFrame
+   ```html
+   <!-- entrypoints/example-iframe.html -->
+   <!doctype html>
+   <html lang="en">
+     <head>
+       <meta charset="UTF-8" />
+       <meta name="viewport" content="width=device-width, initial-scale=1.0" />
+       <title>Your Content Script IFrame</title>
+     </head>
+     <body>
+       <!-- ... -->
+     </body>
+   </html>
+   ```
+1. Add the page to the manifest's `web_accessible_resouces`
+   ```ts
+   // wxt.config.ts
+   export default defineConfig({
+     manifest: {
+       web_accessible_resources: [
+         {
+           resources: ['example-iframe.html'],
+           matches: [...],
+         },
+       ],
+     },
+   });
+   ```
+1. Create and mount the IFrame
+
+   ```ts
+   export default defineContentScript({
+     // ...
+     async main(ctx) {
+       // Define the UI
+       const ui = await createIframeUi(ctx, {
+         page: '/example-iframe.html',
+         anchor: '#anchor',
+         type: 'inline',
+         onMount: (wrapper, iframe) => {
+           // Add styles to the iframe like width
+           iframe.width = 123;
+         },
+       });
+
+       // Show UI to user
+       ui.mount();
+     },
+   });
+   ```
+

+
+## Configure Browser Startup
+
+WXT uses [`web-ext` by Mozilla](https://github.com/mozilla/web-ext) to automatically open a browser with the extension installed. You can configure the runner's behavior via the [`runner`](/api/wxt/interfaces/InlineConfig#runner) option, or in a separate gitignored file, `web-ext.config.ts`.
+
+:::code-group
+
+```ts [wxt.config.ts]
+import { defineConfig } from 'wxt';
+
+export default defineConfig({
+  runner: {
+    // Runner config
+  },
+});
+```
+
+```ts [web-ext.config.ts]
+import { defineRunnerConfig } from 'wxt';
+
+export default defineRunnerConfig({
+  // Runner config
+});
+```
+
+:::
+
+### Browser Binaries
+
+`web-ext`'s browser discovery is very limitted. By default, it only guesses at where Chrome and Firefox are installed. If you've customized your install locations, you may need to tell `web-ext` where the binaries/executables are located using the [`binaries` option](/api/wxt/interfaces/ExtensionRunnerConfig#binaries). For other Chromium based browsers, like Edge or Opera, you'll need to explicitly list them in the `binaries` option as well, otherwise they will open in Chrome by default.
+
+```ts
+// ~/web-ext.config.ts
+import { defineRunnerConfig } from 'wxt';
+
+export default defineRunnerConfig({
+  binaries: {
+    chrome: '/path/to/chrome-beta', // Use Chrome Beta instead of regular Chrome
+    firefox: 'firefoxdeveloperedition', // Use Firefox Developer Edition instead of regular Firefox
+    edge: '/path/to/edge', // Open MS Edge when running "wxt -b edge"
+  },
+});
+```
+
+:::tip
+When configuring browser binaries, it's helpful to put them in `~/web-ext.config.ts` instead of the project directory's `web-ext.config.ts` file. When placed in your home directory (`~/`), this config will be used by all WXT projects, so you only need to configure the binaries once.
+:::
+
+### Other options
+
+You can customize other options as well, like startup URLs, profiles, or additional command line arguments:
+
+```ts
+// web-ext.config.ts
+import { defineRunnerConfig } from 'wxt';
+
+export default defineRunnerConfig({
+  startUrls: ['https://google.com', 'https://duckduckgo.com'],
+  chromiumProfile: '/path/to/profile/to/use',
+  chromiumArgs: ['--window-size=400x300'],
+});
+```
+
+For a full list of options, see the [API Reference](/api/wxt/interfaces/ExtensionRunnerConfig).
+
+## Reload the Extension
+
+Normally, to manually reload an extension, you have to visit `chrome://extensions` and click the reload button for your extension.
+
+When running `wxt` command to start the dev server, WXT adds a keyboard shortcut, `ctrl+E` for Windows/Linux and `cmd+E` for Mac, that reloads the extension when pressed, without visiting `chrome://extensions`.
+
+:::note
+This shortcut is only available during development, and is not be added to your extension when running `wxt build` or `wxt-zip`.

docs/guide/entrypoints.md

+# Defining Entrypoints
+
+An "entrypoint" is any HTML, JS, or CSS file that needs to be bundled and included with the extension.
+
+Entrypoints may or may not be listed in the extension's `manifest.json`.
+
+## `/entrypoints` Directory
+
+In WXT, entrypoints are defined by adding a file to the `entrypoints/` directory.
+
+For example, a project that looks like this:
+
+```
+<rootDir>
+└─ entrypoints/
+   ├─ background.ts
+   ├─ content.ts
+   ├─ injected.ts
+   └─ popup.html
+```
+
+would result in the following `manifest.json`:
+
+```json
+{
+  // ...
+  "manifest_version": 3,
+  "action": {
+    // ...
+    "default_popup": "popup.html"
+  },
+  "background": {
+    // ...
+    "service_worker": "background.js"
+  },
+  "content_scripts": [
+    {
+      // ...
+      "js": ["content-scripts/content.js"]
+    }
+  ]
+}
+```
+
+If a file uses a special name recognized by WXT, it will be added to the manifest. In this case:
+
+- `popup.html` &rarr; `action.default_popup`
+- `content.ts` &rarr; `content_scripts.0.js.0`
+- `background.ts` &rarr; `background.service_worker`
+
+But not all entrypoints are added to the `manifest.json`. If the filename is not recognized by WXT, they are still built and included in the extension, but they are considered "unlisted" and are not apart of the manifest.
+
+In this case, `injected.ts` gets output to `<outdir>/injected.js` and is accessible via `browser.runtime.getURL("/injected.js")`.
+
+:::info
+See [`/entrypoints` folder](/entrypoints/background) documentation for a full list of recognized entrypoint filenames.
+:::
+
+## Entrypoint Options
+
+Some entrypoints, like content scripts, actions, or the background, can recieve additional options.
+
+In HTML files, options are listed as `meta` tags:
+
+```html
+<html>
+  <head>
+    <!-- Defining the popup's "default_icon" field -->
+    <meta name="manifest.default_icon" content="{ '16': '/icon/16.png' }" />
+  </head>
+</html>
+```
+
+In TS files, options are apart of the file's default export:
+
+```ts
+export default defineContentScript({
+  matches: ['*://*.google.com/*'],
+  runAt: 'document_start',
+  main() {
+    // ...
+  },
+});
+```
+
+:::info
+For a full list of entrypoints and each of their options, see the [`/entrypoints` folder](/entrypoints/background) documentation.
+:::
+
+### Side Effects
+
+You cannot use imported variables outside the `main` function is JS entrypoints. This includes options, as shown below:
+
+```ts
+// entrypoints/content.ts
+import { GOOGLE_MATCHES } from '~/utils/match-patterns';
+
+export default defineContentScript({
+  matches: GOOGLE_MATCHES,
+  main() {
+    // ...
+  },
+});
+```
+
+```
+$ wxt build
+wxt build
+
+WXT 0.14.1
+ℹ Building chrome-mv3 for production with Vite 5.0.5
+✖ Command failed after 360 ms
+
+[8:55:54 AM]  ERROR  entrypoints/content.ts: Cannot use imported variable "GOOGLE_MATCHES" before main function. See https://wxt.dev/guide/entrypoints.html#side-effects
+```
+
+This throws an error because WXT needs to import each entrypoint during the build process to extract its definition (containing the `match`, `run_at`, `include`/`exclude`, etc.) to render the `manifest.json` correctly. Before loading an entrypoint, a transformation is applied to remove all imports. This prevents imported modules (local or NPM) with side-effects from running during the build process, potentially throwing an error.
+
+:::details Why?
+
+When importing your entrypoint to get its definition, the file is imported in a **_node environement_**, and doesn't have access to the `window`, `chrome`, or `browser` globals a web extension ususally has access to. If WXT doesn't remove all the imports from the file, the imported modules could try and access one of these variables, throwing an error.
+
+:::
+
+:::warning
+See [`wxt-dev/wxt#336`](https://github.com/wxt-dev/wxt/issues/336) to track the status of this bug.
+:::
+
+Usually, this error occurs when you try to extract options into a shared file or try to run code outside the `main` function. To fix the example from above, use litteral values when defining an entrypoint instead of importing them:
+
+```ts
+import { GOOGLE_MATCHES } from '~/utils/match-patterns'; // [!code --]
+
+export default defineContentScript({
+  matches: GOOGLE_MATCHES, // [!code --]
+  matches: ['*//*.google.com/*'], // [!code ++]
+  main() {
+    // ...
+  },
+});
+```

+# Migrate to WXT
+
+> If you have problems migrating to WXT, feel free to ask for help in GitHub by [starting a discussion](https://github.com/wxt-dev/wxt/discussions/new?category=q-a)!
+
+## Overview
+
+Always start by generating a new vanilla project and merging it into your project one file at a time.
+
+```sh
+cd path/to/your/project
+pnpx wxt@latest init example-wxt --template vanilla
+```
+
+In general, you'll need to:
+
+<input type="checkbox" /> Install `wxt`<br />
+<input type="checkbox" /> Update/create `package.json` scripts to use `wxt` (don't forget about `postinstall`)<br />
+<input type="checkbox" /> Move entrypoints into `entrypoints/` directory<br />
+<input type="checkbox" /> Move assets into either the `assets/` or `public/` directories<br />
+<input type="checkbox" /> Move manifest.json content into `wxt.config.ts`<br />
+<input type="checkbox" /> Convert custom import syntax to be compatible with Vite<br />
+<input type="checkbox" /> Add a default export to JS entrypoints<br />
+<input type="checkbox" /> Use the `browser` global instead of `chrome`<br />
+<input type="checkbox" /> Compare final `manifest.json` files, making sure permissions and host permissions are unchanged<br />
+<input type="checkbox" /> Extension output by `wxt build` works the same way as before the migration<br />
+
+Every project is different, so there's no one-solution-fits-all to migrating your project. Just make sure `wxt dev` runs, `wxt build` results in a working extension, and the list of permissions in the `manifest.json` hasn't changed. If all that looks good, you've finished migrating your extension!
+
+## Popular Tools/Frameworks
+
+Here's specific steps for other popuplar frameworks/build tools.
+
+### `vite-plugin-web-extension`
+
+Since you're already using Vite, it's a simple refactor.
+
+1. Install `wxt`
+2. Move and refactor your entrypoints to WXT's style (with a default export)
+3. Update package.json scripts to use `wxt`
+4. Add `"postinstall": "wxt prepare"` script
+5. Move the `manifest.json` into `wxt.config.ts`
+6. Move any custom settings from `vite.config.ts` into `wxt.config.ts`'s
+7. Compare `dist/manifest.json` to `.output/*/manifest.json`, they should have the same content as before. If not, tweak your entrypoints and config to get as close as possible.
+
+### `plasmo`
+
+1. Install `wxt`
+2. Move entrypoints into `entrypoints/` directory, merging the named exports used to configure your JS entrypoints into WXT's default export
+3. Move public `assets/*` into the `public/` directory
+4. If you use CSUI, migrate to WXT's `createContentScriptUi`
+5. Convert Plasmo's custom import resolutions to Vite's
+6. If importing remote code via a URL, add a `url:` prefix so it works with WXT
+7. Compare your output `manifest.json` files from before the migration to after the migration. They should have the same content. If not, tweak your entrypoints and config to get as close as possible.

+# Multiple Browsers
+
+You can build an extension for any combination of browser and manifest verison. Different browsers and manifest versions support different APIs and entrypoints, so be sure to check that your extension functions as expected for each target.
+
+Separate build targets are written to their own output directories:
+
+```
+<rootDir>
+└─ .output
+   ├─ chrome-mv3
+   ├─ firefox-mv2
+   ├─ edge-mv3
+   └─ ...
+```
+
+## Target Browser
+
+To build for a specific browser, pass the `-b --browser` flag from the CLI:
+
+```
+
+wxt --browser firefox
+wxt build --browser firefox
+
+```
+
+By default, it will build for `chrome`. When excluding the [manifest version flags](#target-manifest-version), it will default to the commonly accepted manifest version for that browser.
+
+| Browser          | Default Manifest Version |
+| ---------------- | :----------------------: |
+| `chrome`         |            3             |
+| `firefox`        |            2             |
+| `safari`         |            2             |
+| `edge`           |            3             |
+| Any other string |            3             |
+
+:::tip
+To configure which browser is opened when running dev mode via `wxt -b <browser>`, see the [Development docs](/guide/development#configure-browser-startup) docs.
+:::
+
+## Target Manifest Version
+
+To build for a specific manifest version, pass either the `--mv2` flag or `--mv3` flag from the CLI.
+
+```sh
+wxt --mv2
+wxt build --mv2
+```
+
+When the `-b --browser` flag is not passed, it defaults to `chrome`. So here, we're targetting MV2 for Chrome.
+
+## Customizing Entrypoints
+
+There are several ways to customize entrypoint definitions per browser.
+
+First, you can use either the `include` or `exclude` option to include or exclude the entrypoint from specific browsers. Here are some examples
+
+:::code-group
+
+```ts [Background]
+export default defineBackground({
+  // Only include a background script when targeting chrome
+  include: ['chrome'],
+});
+```
+
+```ts [Content Script]
+export default defineContentScript({
+  // Do not add this content script to the manifest when targeting firefox
+  exclude: ['firefox'],
+});
+```
+
+```html [HTML page]
+<!-- entrypoints/options.html -->
+<html>
+  <head>
+    <!-- Don't include the options page for safari -->
+    <meta name="manifest.exclude" content="['safari']" />
+  </head>
+</html>
+```
+
+:::
+
+Second, you can change individual options per-browser:
+
+:::code-group
+
+```ts [Background]
+export default defineBackground({
+  persistent: {
+    // Use a non-persistent background script for just safari
+    safari: false,
+  },
+});
+```
+
+```ts [Content Script]
+export default defineContentScript({
+  matches: {
+    // Run the content script on different pages for each browser
+    chrome: ['*://*.google.com/*'],
+    firefox: ['*://*.duckduckgo.com/*'],
+    edge: ['*://*.bing.com/*'],
+  },
+});
+```
+
+:::
+
+:::warning
+Only `defineBackground` and `defineContentScript` support per-browser options right now.

+# Storage API
+
+WXT provides a simplified API to replace the `browser.storage.*` APIs. Use the `storage` auto-import from `wxt/storage` or import it manually to get started:
+
+```ts
+import { storage } from 'wxt/storage';
+```
+
+[[toc]]
+
+## Basic Usage
+
+All storage keys must be prefixed by their storage area.
+
+```ts
+// ❌ This will throw an error
+await storage.getItem('installDate');
+
+// ✅ This is good
+await storage.getItem('local:installDate');
+```
+
+You can use `local:`, `session:`, `sync:`, or `managed:`.
+
+If you use TypeScript, you can add a type parameter to most methods to specify the expected type of the key's value:
+
+```ts
+await storage.getItem<number>('local:installDate');
+await storage.watch<number>(
+  'local:installDate',
+  (newInstallDate, oldInstallDate) => {
+    // ...
+  },
+);
+await storage.getMeta<{ v: number }>('local:installDate');
+```
+
+## Watchers
+
+To listen for storage changes, use the `storage.watch` function. It lets you setup a listener for a single key:
+
+```ts
+const unwatch = storage.watch<number>('local:counter', (newCount, oldCount) => {
+  console.log('Count changed:', { newCount, oldCount });
+});
+```
+
+To remove the listener, call the returned `unwatch` function:
+
+```ts
+const unwatch = storage.watch(...);
+
+// Some time later...
+unwatch();
+```
+
+## Metadata
+
+`wxt/storage` also supports setting metadata for keys, stored at `key + "$"`. Metadata is a collection of properties associated with a key. It might be a version number, last modified date, etc.
+
+[Other than versioning](#versioning-and-migrations), you are responsible for managing a field's metadata:
+
+```ts
+await Promise.all([
+  storage.setItem('local:preference', true),
+  storage.setMeta('local:preference', { lastModified: Date.now() }),
+]);
+```
+
+When setting different properties of metadata from multiple calls, the properties are combined instead of overwritten:
+
+```ts
+await storage.setMeta('local:preference', { lastModified: Date.now() });
+await storage.setMeta('local:preference', { v: 2 });
+
+await storage.getMeta('local:preference'); // { v: 2, lastModified: 1703690746007 }
+```
+
+You can remove all metadata associated with a key, or just specific properties:
+
+```ts
+// Remove all properties
+await storage.removeMeta('local:preference');
+
+// Remove one property
+await storage.removeMeta('local:preference', 'lastModified');
+
+// Remove multiple properties
+await storage.removeMeta('local:preference', ['lastModified', 'v']);
+```
+
+## Defining Storage Items
+
+Writing the key and type parameter for the same key over and over again can be annoying. As an alternative, you can use `storage.defineItem` to create a "storage item".
+
+Storage items contain the same APIs as the `storage` variable, but you can configure its type, default value, and more in a single place:
+
+```ts
+// utils/storage.ts
+const showChangelogOnUpdate = storage.defineItem<boolean>(
+  'local:showChangelogOnUpdate',
+  {
+    defaultValue: true,
+  },
+);
+```
+
+Now, instead of using the `storage` variable, you can use the helper functions on the storage item you created:
+
+```ts
+await showChangelogOnUpdate.getValue();
+await showChangelogOnUpdate.setValue(false);
+await showChangelogOnUpdate.removeValue();
+const unwatch = showChangelogOnUpdate.watch(() => {
+  // ...
+});
+```
+
+### Versioning and Migrations
+
+You can add versioning to storage items if you expect them to grow or change over time. When defining the first version of an item, start with version 1.
+
+For example, consider a storage item that stores a list of websites that are ignored by an extension.
+
+:::code-group
+
+```ts [v1]
+type IgnoredWebsiteV1 = string;
+
+export const ignoredWebsites = storage.defineItem<IgnoredWebsiteV1[]>(
+  'local:ignoredWebsites',
+  {
+    defaultValue: [],
+    version: 1,
+  },
+);
+```
+
+<!-- prettier-ignore -->
+```ts [v2]
+import { nanoid } from 'nanoid'; // [!code ++]
+
+type IgnoredWebsiteV1 = string;
+interface IgnoredWebsiteV2 { // [!code ++]
+  id: string; // [!code ++]
+  website: string; // [!code ++]
+} // [!code ++]
+
+export const ignoredWebsites = storage.defineItem<IgnoredWebsiteV1[]>( // [!code --]
+export const ignoredWebsites = storage.defineItem<IgnoredWebsiteV2[]>( // [!code ++]
+  'local:ignoredWebsites',
+  {
+    defaultValue: [],
+    version: 1, // [!code --]
+    version: 2, // [!code ++]
+    migrations: { // [!code ++]
+      // Ran when migrating from v1 to v2 // [!code ++]
+      2: (websites: IgnoredWebsiteV1[]): IgnoredWebsiteV2[] => { // [!code ++]
+        return websites.map((website) => ({ id: nanoid(), website })); // [!code ++]
+      }, // [!code ++]
+    }, // [!code ++]
+  },
+);
+```
+
+<!-- prettier-ignore -->
+```ts [v3]
+import { nanoid } from 'nanoid';
+
+type IgnoredWebsiteV1 = string;
+interface IgnoredWebsiteV2 {
+  id: string;
+  website: string;
+}
+interface IgnoredWebsiteV3 { // [!code ++]
+  id: string; // [!code ++]
+  website: string; // [!code ++]
+  enabled: boolean; // [!code ++]
+} // [!code ++]
+
+export const ignoredWebsites = storage.defineItem<IgnoredWebsiteV2[]>( // [!code --]
+export const ignoredWebsites = storage.defineItem<IgnoredWebsiteV3[]>( // [!code ++]
+  'local:ignoredWebsites',
+  {
+    defaultValue: [],
+    version: 2, // [!code --]
+    version: 3, // [!code ++]
+    migrations: {
+      // Ran when migrating from v1 to v2
+      2: (websites: IgnoredWebsiteV1[]): IgnoredWebsiteV2[] => {
+        return websites.map((website) => ({ id: nanoid(), website }));
+      },
+      // Ran when migrating from v2 to v3 // [!code ++]
+      3: (websites: IgnoredWebsiteV2[]): IgnoredWebsiteV3[] => { // [!code ++]
+        return websites.map((website) => ({ ...website, enabled: true })); // [!code ++]
+      }, // [!code ++]
+    },
+  },
+);
+```
+
+:::
+
+:::info
+Internally, this uses a metadata property called `v` to track the value's current version.
+:::
+
+In this case, we thought that the ignored website list might change in the future, and were able to setup a versioned storage item from the start.
+
+Realistically, you won't know a item needs versioned until you need to change it's schema. Thankfully, it's simple to add versioning to an unversioned storage item.
+
+When a previous version isn't found, WXT assumes the version was `1`. That means you just need to set `version: 2` and add a migration for `2`, and it will just work!
+
+Lets look at the same ignored websites example from before, but start with an unversioned item this time:
+
+:::code-group
+
+```ts [Unversioned]
+export const ignoredWebsites = storage.defineItem<string[]>(
+  'local:ignoredWebsites',
+  {
+    defaultValue: [],
+  },
+);
+```
+
+<!-- prettier-ignore -->
+```ts [v2]
+import { nanoid } from 'nanoid'; // [!code ++]
+
+// Retroactively add a type for the first version // [!code ++]
+type IgnoredWebsiteV1 = string; // [!code ++]
+interface IgnoredWebsiteV2 { // [!code ++]
+  id: string; // [!code ++]
+  website: string; // [!code ++]
+} // [!code ++]
+
+export const ignoredWebsites = storage.defineItem<string[]>( // [!code --]
+export const ignoredWebsites = storage.defineItem<IgnoredWebsiteV2[]>( // [!code ++]
+  'local:ignoredWebsites',
+  {
+    defaultValue: [],
+    version: 2, // [!code ++]
+    migrations: { // [!code ++]
+      // Ran when migrating from v1 to v2 // [!code ++]
+      2: (websites: IgnoredWebsiteV1[]): IgnoredWebsiteV2[] => { // [!code ++]
+        return websites.map((website) => ({ id: nanoid(), website })); // [!code ++]
+      }, // [!code ++]
+    }, // [!code ++]
+  },
+);
+```

+# Testing
+
+## Official Frameworks
+
+WXT officially supports [Vitest](https://vitest.dev/) for unit tests and either [Playwright](https://playwright.dev/) or [Puppeteer](https://pptr.dev/) for E2E tests against Chromium browsers.
+
+For details setting up each testing framework, see the official examples:
+
+<ExampleList tag="testing" />
+
+### Unofficial Frameworks
+
+Puppeteer and Playwright are the only E2E test runners that support Chrome Extensions. There are no other options at the time of writing.
+
+There are other options for unit tests however, like [Jest](https://jestjs.io/), [Mocha](https://mochajs.org/), or [`node:test`](https://nodejs.org/api/test.html). **_WXT does not claim to support any of them_** because none of them support all of WXT's features, like TypeScript or auto-imports.
+
+If you want to try to use a different framework for unit tests, you will need to configure the environment manually:
+
+- **Auto-imports**: Add `unimport` to your test environment or disable them by setting `imports: false` in your `wxt.config.ts` file
+- **`browser` mock**: Mock the `webextension-polyfill` module globally with `wxt/dist/virtual/mock-browser.js`
+- **[Remote Code Bundling](/guide/remote-code)**: If you use it, configure your environment to handle the `url:` module prefix
+- **Global Variables**: If you consume them, manually define globals provided by WXT (like `__BROWSER__`) by adding them to the global scope before accessing them (`globalThis.__BROWSER__ = "chrome"`)
+- **Import paths**: If you use the `@/` or `~/` path aliases, add them to your test environment
+
+[Here's how Vitest is configured](https://github.com/wxt-dev/wxt/blob/main/src/testing/wxt-vitest-plugin.ts) for reference.
