+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+- Demonstrating empathy and kindness toward other people
+- Being respectful of differing opinions, viewpoints, and experiences
+- Giving and gracefully accepting constructive feedback
+- Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+- Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+- The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+- Trolling, insulting or derogatory comments, and personal or political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+- Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+aaronklinker1@gmail.com.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.
+

+title: Introducing <code>#imports</code>
+description: Learn how WXT's new <code>#imports</code> module works and how to use it.
+authors:
+  - name: Aaron Klinker
+    github: aklinker1
+date: 2024-12-06T14:39:00.000Z
+---
+
+WXT v0.20 introduced a new way of manually importing its APIs: **the `#imports` module**. This module was introduced to simplify import statements and provide more visibility into all the APIs WXT provides.
+
+<!-- prettier-ignore -->
+```ts
+import { browser } from 'wxt/browser'; // [!code --]
+import { createShadowRootUi } from 'wxt/utils/content-script-ui/shadow-root'; // [!code --]
+import { defineContentScript } from 'wxt/utils/define-content-script'; // [!code --]
+import { injectScript } from 'wxt/utils/inject-script'; // [!code --]
+import { // [!code ++]
+  browser, createShadowRootUi, defineContentScript, injectScript // [!code ++]
+} from '#imports'; // [!code ++]
+```
+
+The `#imports` module is considered a "virtual module", because the file doesn't actually exist. At build-time, imports are split into individual statements for each API:
+
+:::code-group
+
+```ts [What you write]
+import { defineContentScript, injectScript } from '#imports';
+```
+
+```ts [What the bundler sees]
+import { defineContentScript } from 'wxt/utils/define-content-script';
+import { injectScript } from 'wxt/utils/inject-script';
+```
+
+:::
+
+Think of `#imports` as a convenient way to access all of WXT's APIs from one place, without impacting performance or bundle size.
+
+This enables better tree-shaking compared to v0.19 and below.
+
+:::tip Need to lookup the full import path of an API?
+Open up your project's `.wxt/types/imports-module.d.ts` file.
+:::
+
+## Mocking
+
+When writing tests, you might need to mock APIs from the `#imports` module. While mocking these APIs is very easy, it may not be immediately clear how to accomplish it.
+
+Let's look at an example using Vitest. When [configured with `wxt/testing`](/guide/essentials/unit-testing#vitest), Vitest sees the same transformed code as the bundler. That means to mock an API from `#imports`, you need to call `vi.mock` with the real import path, not `#imports`:
+
+```ts
+import { injectScript } from '#imports';
+import { vi } from 'vitest';
+
+vi.mock('wxt/utils/inject-script')
+const injectScriptMock = vi.mocked(injectScript);
+
+injectScriptMock.mockReturnValueOnce(...);
+```
+
+## Conclusion
+
+You don't have to use `#imports` if you don't like - you can continue importing APIs from their submodules. However, using `#imports` is the recommended approach moving forwards.
+
+- As more APIs are added, you won't have to memorize additional import paths.
+- If breaking changes are made to import paths in future major versions, `#imports` won't break.
+
+Happy Coding 😄
+
+> P.S. Yes, this is exactly how [Nuxt's `#imports`](https://nuxt.com/docs/guide/concepts/auto-imports#explicit-imports) works! We use the exact same library, [`unimport`](https://github.com/unjs/unimport).

 ## WASM
 
-:::warning 🚧 Under construction
-These docs will be coming soon!
-:::
+How a `.wasm` file is loaded varies greatly between packages, but most follow a basic setup: Use a JS API to load and execute the `.wasm` file.
+
+For an extension, that means two things:
+
+1. The `.wasm` file needs to be present in output folder so it can be loaded.
+2. You must import the JS API to load and initialize the `.wasm` file, usually provided by the NPM package.
+
+For an example, let's say you have a content script needs to parse TS code into AST. We'll use [`@oxc-parser/wasm`](https://www.npmjs.com/package/@oxc-parser/wasm) to do it!
+
+First, we need to copy the `.wasm` file to the output directory. We'll do it with a [WXT module](/guide/essentials/wxt-modules):
+
+```ts
+// modules/oxc-parser-wasm.ts
+import { resolve } from 'node:path';
+
+export default defineWxtModule((wxt) => {
+  wxt.hook('build:publicAssets', (_, assets) => {
+    assets.push({
+      absoluteSrc: resolve(
+        'node_modules/@oxc-parser/wasm/web/oxc_parser_wasm_bg.wasm',
+      ),
+      relativeDest: 'oxc_parser_wasm_bg.wasm',
+    });
+  });
+});
+```
+
+Run `wxt build`, and you should see the WASM file copied into your `.output/chrome-mv3` folder!
+
+Next, since this is in a content script and we'll be fetching the WASM file over the network to load it, we need to add the file to the `web_accessible_resources`:
+
+```ts
+// wxt.config.ts
+export default defineConfig({
+  manifest: {
+    web_accessible_resources: [
+      {
+        // We'll use this matches in the cotent script as well
+        matches: ['*://*.github.com/*'],
+        // Use the same path as `relativeDest` from the WXT module
+        resources: ['/oxc_parser_wasm_bg.wasm'],
+      },
+    ],
+  },
+});
+```
+
+And finally, we need to load and initialize the `.wasm` file inside the content script to use it:
+
+```ts
+// entrypoints/content.ts
+import initWasm, { parseSync } from '@oxc-parser/wasm';
+
+export default defineContentScript({
+  matches: '*://*.github.com/*',
+  async main(ctx) {
+    if (!location.pathname.endsWith('.ts')) return;
+
+    // Get text from GitHub
+    const code = document.getElementById(
+      'read-only-cursor-text-area',
+    )?.textContent;
+    if (!code) return;
+    const sourceFilename = document.getElementById('file-name-id')?.textContent;
+    if (!sourceFilename) return;
+
+    // Load the WASM file:
+    await initWasm({
+      module_or_path: browser.runtime.getURL('/oxc_parser_wasm_bg.wasm'),
+    });
+
+    // Once loaded, we can use `parseSync`!
+    const ast = parseSync(code, { sourceFilename });
+    console.log(ast);
+  },
+});
+```
+
+This code is taken directly from `@oxc-parser/wasm` docs with one exception: We manually pass in a file path. In a standard NodeJS or web project, the default path works just fine so you don't have to pass anything in. However, extensions are different. You should always explicitly pass in the full URL to the WASM file in your output directory, which is what `browser.runtime.getURL` returns.
+
+Run your extension, and you should see OXC parse the TS file!

 :::
 
 Once the environment has been polyfilled and your code pre-processed, it's up the entrypoint loader to import your code, extracting the options from the default export.
-
-There are two options for loading your entrypoints:
-
-1. `vite-node` - default as of `v0.19.0`
-2. `jiti` (**DEPRECATED, will be removed in `v0.20.0`**) - Default before `v0.19.0`
-
-## vite-node
-
-Since 0.19.0, WXT uses `vite-node`, the same tool that powers Vitest and Nuxt, to import your entrypoint files. It re-uses the same vite config used when building your extension, making it the most stable entrypoint loader.
-
-## jiti
-
-To enable `jiti`:
-
-```ts
-export default defineConfig({
-  entrypointLoader: 'jiti',
-});
-```
-
-This is the original method WXT used to import TS files. However, because it doesn't support vite plugins like `vite-node`, it does one additional pre-processing step: It removes **_ALL_** imports from your code.
-
-That means you cannot use imported variables outside the `main` function in JS entrypoints, like for content script `matches` or other options:
-
-```ts
-// entrypoints/content.ts
-import { GOOGLE_MATCHES } from '~/utils/match-patterns';
-
-export default defineContentScript({
-  matches: GOOGLE_MATCHES,

+## Mounting UI to dynamic element
+
+In many cases, you may need to mount a UI to a DOM element that does not exist at the time the web page is initially loaded. To handle this, use the `autoMount` API to automatically mount the UI when the target element appears dynamically and unmount it when the element disappears. In WXT, the `anchor` option is used to target the element, enabling automatic mounting and unmounting based on its appearance and removal.

 ## Dealing with SPAs
 
 It is difficult to write content scripts for SPAs (single page applications) and websites using HTML5 history mode for navigation because content scripts are only ran on full page reloads. SPAs and websites that take advantage of HTML5 history mode **_do not perform a full reload when changing paths_**, and thus your content script isn't going to be ran when you expect it to be.

+### Mocking WXT APIs
+

+For example, this is what your write in your source code:

+import { createShadowRootUi } from 'wxt/utils/content-script-ui/shadow-root';

+```ts
+vi.mock("wxt/utils/inject-script", () => ({

+## My component library doesn't work in content scripts!
+
+Component libraries place their CSS in the document's `<head>` by default. When using `createShadowRootUi`, your UI is isolated from the document's styles because it's inside a ShadowRoot.
+
+To fix this, you need to tell your component library to insert it's CSS inside the shadow root. Here's the docs for a couple of popular libraries:
+
+- React
+  - Ant Design: [`StyleProvider`](https://ant.design/docs/react/compatible-style#shadow-dom-usage)
+  - Mantine: [`MantineProvider#getRootElement` and `MantineProvider#cssVariablesSelector`](https://mantine.dev/theming/mantine-provider/)
+
+> If your library isn't listed above, try searching it's docs/issues for "shadow root", "shadow dom", or "css container".
+
+`createShadowRootUi` provides it's own `<head>` element inside the shadow root, so that were you should tell the library to add the CSS. Here's an example with Ant Design:
+
+```tsx
+import { StyleProvider } from '@ant-design/cssinjs'; // [!code ++]
+import ReactDOM from 'react-dom/client';
+import App from './App.tsx';
+
+const ui = await createShadowRootUi(ctx, {
+  name: 'example-ui',
+  position: 'inline',
+  anchor: 'body',
+  onMount: (container) => { // [!code --]
+  onMount: (container, shadow) => { // [!code ++]
+    const cssContainer = shadow.querySelector("head")!; // [!code ++]
+    const root = ReactDOM.createRoot(container);
+    root.render(
+      <StyleProvider container={cssContainer}> // [!code ++]
+        <App />
+      </StyleProvider> // [!code ++]
+    );
+    return root;
+  },
+  onRemove: (root) => {
+    root?.unmount();
+  },
+});
+```
+
+Note that this doesn't effect all component libraries, just ones that inject CSS themselves rather than having you import their CSS. This approach is more prevailent in the React community, but not limited to it. That's why only React libraries are listed above. Vuetify, for example, works just fine because you import its CSS - WXT picks up on this and the CSS is added inside the shadow root automatically:
+
+```ts
+import 'vuetify/styles'; // <-- This line imports the CSS, just like importing a .css file
+import { createVuetify } from 'vuetify';
+```

+2. **Continue using the polyfill**
+   - Install the polyfill and WXT's [new polyfill module](https://www.npmjs.com/package/@wxt-dev/webextension-polyfill):
+     ```sh
+     pnpm i webextension-polyfill @wxt-dev/webextension-polyfill
+     ```
+   - Add the WXT module to your config:
+     ```ts
+     // wxt.config.ts
+     export default defineConfig({
+       modules: ['@wxt-dev/webextension-polyfill'],
+     });
+     ```
+
+Regardless of your choice, the `extensionApi` config has been removed. Remove it from your `wxt.config.ts` file if present:
+
+```ts
+// wxt.config.ts
+export default defineConfig({
+  extensionApi: 'chrome', // [!code --]
+});
+```
+
+Additionally, extension API types have changed. `wxt/browser` now uses types from `@types/chrome` instead of `@types/webextension-polyfill`. You will have to migrate any type imports to use `@types/chrome`'s namespace approach:
+
+<!-- prettier-ignore -->
+```ts
+import type { Runtime } from 'wxt/browser'; // [!code --]
+import { browser } from 'wxt/browser'; // [!code ++]
+
+function getMessageSenderUrl(sender: Runtime.MessageSender): string { // [!code --]
+function getMessageSenderUrl(sender: browser.runtime.MessageSender): string { // [!code ++]
+  // ...
+}
+```
+
+`@types/chrome` are more up-to-date, contain less bugs, and don't have any auto-generated names. So even if you continue to use the polyfill, you will need to update your types to use these types.
+
+### `public/` and `modules/` Directories Moved
+
+The default location for the `public/` and `modules/` directories have changed to better align with standards set by other frameworks (Nuxt, Next, Astro, etc). Now, each path is relative to the project's root directory.
+
+- If you follow the default folder structure, you don't need to make any changes.
+- If you set a custom `srcDir`, you have two options:
+  1.  Keep the folders in the same place and update your project config:
+      ```ts
+      // wxt.config.ts
+      export default defineConfig({
+        srcDir: 'src',
+        publicDir: 'src/public', // [!code ++]
+        modulesDir: 'src/modules', // [!code ++]
+      });
+      ```
+  2.  Move the your `public/` and `modules/` directories to the project root:
+      ```diff
+      <root>/
+      +   modules/
+      +   public/
+          src/
+              components/
+              entrypoints/
+      -       modules/
+      -       public/
+              utils/
+          wxt.config.ts
+      ```
+
+### Import Path Changes
+
+The APIs exported by `wxt/sandbox`, `wxt/client`, or `wxt/storage` have moved to `wxt/utils/*`.
+
+To upgrade, replace these imports with the new `#imports` module:
+
+```ts
+import { storage } from 'wxt/storage'; // [!code --]
+import { defineContentScript } from 'wxt/sandbox'; // [!code --]
+import { ContentScriptContext, useAppConfig } from 'wxt/client'; // [!code --]
+import { storage } from '#imports'; // [!code ++]
+import { defineContentScript } from '#imports'; // [!code ++]
+import { ContentScriptContext, useAppConfig } from '#imports'; // [!code ++]
+```
+
+You can combine the imports into a single import statement, but it's easier to just find/replace each statement.
+
+:::tip
+Before types will work, you'll need to run `wxt prepare` after installing v0.20 to generate the new TypeScript declarations.
+:::
+
+Read more about the new `#imports` module in the [blog post](/blog/2024-12-06-using-imports-module).
+
+### `createShadowRootUi` CSS Changes
+
+WXT now resets styles inherited from the webpage (`visibility`, `color`, `font-size`, etc.) by setting `all: initial` inside the shadow root.
+
+If you use `createShadowRootUi`:
+
+1. Double check that your UI looks the same as before.
+2. If you have any manual CSS resets to override a page style, you can remove them:
+
+   <!-- prettier-ignore -->
+   ```css
+   /* entrypoints/reddit.content/style.css */
+   body { /* [!code --] */
+     /* Override Reddit's default "hidden" visibility on elements */ /* [!code --] */
+     visibility: visible !important; /* [!code --] */
+   } /* [!code --] */
+   ```
+
+:::warning
+This doesn't effect `rem` units. You should continue using `postcss-rem-to-px` or an equivalent library if the webpage sets the HTML element's `font-size`.
+:::
+
+If you run into problems with the new behavior, you can disable it and continue using your current CSS:
+
+```ts
+const ui = await createShadowRootUi({
+  inheritStyles: true, // [!code ++]
+  // ...
+});
+```
+
+### Default Output Directories Changed
+
+The default value for [`outDirTemplate`](/api/reference/wxt/interfaces/InlineConfig#outdirtemplate) has changed. Now, different build modes are output to different directories:
+
+- `--mode production`: `.output/chrome-mv3` (unchanged)
+- `--mode development`: `.output/chrome-mv3-dev` (`-dev` suffix)
+- `--mode custom`: `.output/chrome-mv3-custom` (`-[mode]` suffix)
+
+To revert and use the old behavior, writing all output to the same directory, set `outDirTemplate` option:
+
+```ts
+// wxt.config.ts
+export default defineConfig({
+  outDirTemplate: '{{browser}}-mv{{manifestVersion}}', // [!code ++]
+});
+```
+
+### `runner` APIs Renamed
+
+To improve consistency with the `web-ext.config.ts` file, the "runner" APIs have been renamed. You can continue using the old names, but they have been deprecated and will be removed in a future version:
+
+1. The `runner` option has been renamed to `webExt`:
+   ```ts
+   // wxt.config.ts
+   export default defineConfig({
+     runner: { // [!code --]
+     webExt: { // [!code ++]
+       startUrls: ["https://wxt.dev"],
+     },
+   });
+   ```
+2. `defineRunnerConfig` has been renamed to `defineWebExtConfig`:
+   ```ts
+   // web-ext.config.ts
+   import { defineRunnerConfig } from 'wxt'; // [!code --]
+   import { defineWebExtConfig } from 'wxt'; // [!code ++]
+   ```
+3. The `ExtensionRunnerConfig` type has been renamed to `WebExtConfig`
+   ```ts
+   import type { ExtensionRunnerConfig } from 'wxt'; // [!code --]
+   import type { WebExtConfig } from 'wxt'; // [!code ++]
+   ```
+
+### Load Config as ESM
+
+`wxt.config.ts` and `web-ext.config.ts` are now loaded as ESM modules. Previously, they were loaded as CJS.
+
+If you're using any CJS APIs, like `__filename` or `__dirname`, replace them with their ESM counterparts, like `import.meta.filename` or `import.meta.dirname`.
+
+### Deprecated APIs Removed
+
+- `entrypointLoader` option: WXT now uses `vite-node` for importing entrypoints during the build process.
+  > This was deprecated in v0.19.0, see the [v0.19 section](#v0-18-5-rarr-v0-19-0) for migration steps.
+- `transformManifest` option: Use the `build:manifestGenerated` hook to transform the manifest instead:
+  <!-- prettier-ignore -->
+  ```ts
+  // wxt.config.ts
+  export default defineConfig({
+    transformManifest(manifest) { // [!code --]
+    hooks: { // [!code ++]
+      'build:manifestGenerated': (_, manifest) => { // [!code ++]
+         // ...
+      }, // [!code ++]
+    },
+  });

+## Bulk Operations

+When getting or setting multiple values in storage, you can perform bulk operations to improve performance by reducing the number of individual storage calls. The `storage` API provides several methods for performing bulk operations:
+
+- **`getItems`** - Get multiple values at once.
+- **`getMetas`** - Get metadata for multiple items at once.
+- **`setItems`** - Set multiple values at once.
+- **`setMetas`** - Set metadata for multiple items at once.

+const userId = storage.defineItem('local:userId');
+
+await storage.setItems([
+  { key: 'local:installDate', value: Date.now() },
+  { item: userId, value: generateUserId() },
+]);

+- Non-WXT projects can use the storage wrapper.
+- We can make breaking changes to the API separately.

+# WXT Storage
+
+[Changelog](https://github.com/wxt-dev/wxt/blob/main/packages/storage/CHANGELOG.md) • [Docs](https://wxt.dev/storage.html)
+
+A simplified wrapper around the extension storage APIs.
+
+## Installation
+
+### With WXT
+
+This module is built-in to WXT, so you don't need to install anything.
+
+```ts
+import { storage } from 'wxt/storage';
+```
+
+If you use auto-imports, `storage` is auto-imported for you, so you don't even need to import it!
+
+### Without WXT
+
+Install the NPM package:
+
+```sh
+npm i @wxt-dev/storage
+pnpm add @wxt-dev/storage
+yarn add @wxt-dev/storage
+bun add @wxt-dev/storage
+```
+
+```ts
+import { storage } from '@wxt-dev/storage';
+```
+
+## Usage
+
+Read full docs on the [documentation website](https://wxt.dev/storage.html).
