 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!

-# 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/go-further/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 `import.meta.env.BROWSER`) by adding them to the global scope before accessing them (`import.meta.env.BROWSER = "chrome"`)
-- **Import paths**: If you use the `@/` or `~/` path aliases, add them to your test environment

+
+:::warning Nuxt Users
+If you're familiar with Nuxt, this file is meant to be a direct equivalent to Nuxt's `app.config.ts` file.
+
+However, some of Nuxt's features, like overriding the app config based on a `.env` file or automatically generating the config's types, are not implemented. They are planned, just not implemented yet. Feel free to open a PR!
+:::
+
+## Overview
+
+Define runtime configuration in a single place.
+
+```ts
+// <srcDir>/app.config.ts
+import { defineAppConfig } from 'wxt/sandbox';
+
+// Define types for your config
+declare module 'wxt/sandbox' {
+  export interface WxtAppConfig {
+    theme?: 'light' | 'dark';
+  }
+}
+
+export default defineAppConfig({
+  theme: 'dark',
+});
+```
+
+Then access the config in your extension by calling `useAppConfig`:
+
+```ts
+console.log(useAppConfig()); // { theme: "dark" }
+```
+
+## Environment Variables
+
+If you have a `.env` file, you can access any variables defined in it here. You can convert them to better types (like booleans), add types for them, or leave them as is.
+
+```txt
+# .env
+VITE_BUG_REPORTING_DISABLED=true
+VITE_API_KEY=...
+```
+
+```ts
+// <srcDir>/app.config.ts
+
+declare module 'wxt/sandbox' {
+  export interface WxtAppConfig {
+    bugReportingDisabled: boolean;
+    apiKey?: string;
+  }
+}
+
+export default defineAppConfig({
+  bugReportingDisabled: process.env.VITE_BUG_REPORTING_DISABLED === 'true',
+  apiKey: process.env.VITE_API_KEY,
+});
+```
+
+> You don't have to do this, you can use `process.env.VITE_*` anywhere in your runtime code, but putting them here consolidates them to one place and defines what variables are expected.

 ## ESLint
 
-ESLint doesn't understand auto-imports; it thinks all auto-imported variables are undeclared globals and will report lint errors for each. To fix this, extend the ESLint file generated inside the `.wxt` directory:
-
-```js
-// .eslintrc.js
-module.exports = {
-  extends: ['./.wxt/eslintrc-auto-import.json'],
-};
-```
-
-By default, this file will be generated when ESLint is a direct dependency. If ESLint is a subdependency or your project is a monorepo, it may not be generated automatically. In this case, you can tell WXT to generate it:
+ESLint doesn't know about the auto-imported variables unless they are explicitly defined in the `globals` config. By default, WXT will generate the config if it detects ESLint is installed in your project. If the config isn't generated automatically, you can manually tell WXT to generate it.
 
 ```ts
 // wxt.config.ts
 export default defineConfig({
   imports: {
     eslintrc: {
-      enabled: true,
+      enabled: 8, // Generate ESLint v8 compatible config
+      // or
+      enabled: 9, // Generate ESLint v9 compatible config
     },
   },
 });
 ```
+
+### ESLint 9 and above
+
+WXT supports the new "flat config" file format. Just import the generated file and add it to the array of config to extend.
+
+```js
+// eslint.config.mjs
+import autoImports from './.wxt/eslint-auto-imports.mjs';
+
+export default [autoImports];
+```
