+title: Configuring Vite
+description: NativeScript apps can be bundled with Vite.

+
+All NativeScript apps can be bundled using [Vite](https://vite.dev/). To manage the required configuration, we maintain the `@nativescript/vite` package.
+
+## Setup
+
+Install the plugin.
+
+```bash
+npm install @nativescript/vite
+```
+
+## Configure
+
+The plugin comes with several framework integrations.
+
+### Vue
+
+```ts
+import { defineConfig, mergeConfig, UserConfig } from 'vite';
+import { vueConfig } from '@nativescript/vite';
+
+export default defineConfig(({ mode }): UserConfig => {
+	return mergeConfig(vueConfig({ mode }), {});
+});
+```
+
+### Angular
+
+```ts
+import { defineConfig, mergeConfig, UserConfig } from 'vite';
+import { angularConfig } from '@nativescript/vite';
+
+export default defineConfig(({ mode }): UserConfig => {
+	return mergeConfig(angularConfig({ mode }), {});
+});
+```
+
+### Solid
+
+```ts
+import { defineConfig, mergeConfig, UserConfig } from 'vite';
+import { solidConfig } from '@nativescript/vite';
+
+export default defineConfig(({ mode }): UserConfig => {
+	return mergeConfig(solidConfig({ mode }), {});
+});
+```
+
+### Svelte
+
+```ts
+import { defineConfig, mergeConfig, UserConfig } from 'vite';
+import { solidConfig } from '@nativescript/vite';
+
+export default defineConfig(({ mode }): UserConfig => {
+	return mergeConfig(solidConfig({ mode }), {});
+});
+```
+
+### React
+
+```ts
+import { defineConfig, mergeConfig, UserConfig } from 'vite';
+import { reactConfig } from '@nativescript/vite';
+
+export default defineConfig(({ mode }): UserConfig => {
+	return mergeConfig(reactConfig({ mode }), {});
+});
+```
+
+### TypeScript (XML view)
+
+```ts
+import { defineConfig, mergeConfig, UserConfig } from 'vite';
+import { typescriptConfig } from '@nativescript/vite';
+
+export default defineConfig(({ mode }): UserConfig => {
+	return mergeConfig(typescriptConfig({ mode }), {});
+});
+```
+
+The above config configures most things required to bundle a NativeScript application. 
+
+This page contains examples of common things you might want to change in the [Examples of configurations section](#configuration-examples) - for anything else not mentioned here, refer to the [Vite documentation](https://vite.dev/config/).
+
+## CLI Flags
+
+When running a NativeScript app the following flags have an effect on the final vite config
+
+### --no-hmr
+
+Disable HMR (enabled by default)
+
+### --env.verbose
+
+Prints verbose logs and the internal config before building
+
+### Additional flags
+
+Additional env flags that are usually passed by the CLI automatically
+
+- `--env.appPath` - path to the app source (same as `appPath` in the `nativescript.config.ts`)
+- `--env.appResourcesPath` - path to App_Resources (same as `appResourcesPath` in the `nativescript.config.ts`)
+- `--env.nativescriptLibPath` - path to the currently running CLI's library.
+- `--env.android` - `true` when running on android
+- `--env.ios` - `true` when running on ios
+- `--env.platform=<platform>` - for specifying the platform to use. Can be `android` or `ios`, or a custom platform in the future.
+- `--env.hmr` - `true` when building with HMR enabled
+
+## Global "magic" variables
+
+We define a few useful globally available variables that you can use to alter logic in your applications.
+
+- `__DEV__` - `true` when webpack is building in development mode
+  ```ts
+  if (__DEV__) {
+    // we are running a dev build
+  }
+  ```
+- `__ANDROID__`, `true` when the platform is Android
+  ```ts
+  if (global.isAndroid) {
+    // we are running on android
+  }
+  ```
+- `__IOS__`, `true` when the platform is iOS
+  ```ts
+  if (__IOS__) {
+    // we are running on iOS
+  }
+  ```
+
+::: details The following variables are also defined, but are primarily intended to be used by NativeScript Core internally, or plugins that wish to use these.
+
+- `__NS_ENV_VERBOSE__` - `true` when `--env.verbose` is set
+- `__CSS_PARSER__` - the CSS parser used by NativeScript Core. The value is set based on the `cssParser` value in the `nativescript.config.ts` and defaults to `css-tree`
+- `__UI_USE_XML_PARSER__` - a flag used by NativeScript Core to disable the XML parser when it's not used
+- `__UI_USE_EXTERNAL_RENDERER__` - a flag used by NativeScript Core to disable registering global modules when an external renderer is used.
+
+:::
+
+## Configuration examples
+
+Here are some common examples of things you may want to do in your `vite.config.ts`.
+
+### Adding a copy rule
+
+```ts
+import { defineConfig, mergeConfig, UserConfig } from 'vite';
+import { typescriptConfig } from '@nativescript/vite';
+import path from 'path';
+import { viteStaticCopy } from 'vite-plugin-static-copy';
+
+export default defineConfig(({ mode }): UserConfig => {
+	const base = typescriptConfig({ mode });
+	const projectRoot = path.resolve(__dirname);
+	const testImagePath = path.resolve(projectRoot, 'src/ui/image/700x50.png');
+	return mergeConfig(base, {
+		plugins: [
+      viteStaticCopy({
+				targets: [{ src: testImagePath, dest: 'ui/image' }],
+			})
+    ],
+	});
+});
+
+```
+
+## Plugin API
+
+NativeScript plugins can provide a `nativescript.vite.mjs` file in their root folder (next to `package.json`), and `@nativescript/vite` will include these configs when resolving the final config.
+
+For example, a plugin could return custom processing:
+
+```js
+import { createRequire } from "module";
+const require = createRequire(import.meta.url);
+
+let postcssConfig = "./postcss.config.js";
+
+try {
+  const twV4 = require("@tailwindcss/postcss");
+  const nsTailwind = require("@nativescript/tailwind");
+  postcssConfig = { plugins: [twV4, nsTailwind] };
+} catch (e2) {
+  console.warn(
+    "Inline PostCSS unavailable, falling back to ./postcss.config.js"
+  );
+}
+
+export default () => {
+  return {
+    css: {
+      postcss: postcssConfig,
+    },
+  };
+};
+```
