+
+Tailwind CSS v4 brings revolutionary changes to how we configure and use the popular utility-first framework. The simplified setup eliminates configuration files and complex PostCSS setups - you just install, import, and start building. But when working in NPM workspaces or monorepos, there's still one crucial challenge: **how do you tell Tailwind which packages to scan for classes?**
+
+This guide walks you through setting up Tailwind v4 with Vite in an NPM workspace, then shows you how to automate the configuration using Nx Sync Generators to **eliminate manual maintenance**.

+
+## Setting up Tailwind v4
+
+[Tailwind v4](https://tailwindcss.com/blog/tailwindcss-v4) introduced some nice simplifications when it comes to configuring Tailwind:
+
+- **No more `tailwind.config.js`** - The framework works out of the box
+- **Minimal dependencies** - Just `tailwindcss` and `@tailwindcss/vite` for Vite projects
+- **Simple CSS import** - Add `@import "tailwindcss"` to your stylesheet and you're ready
+
+Since we're using Vite in this workspace, we can leverage the dedicated Tailwind Vite plugin instead of PostCSS configuration. Here's what you need:
+
+Install the required packages at your workspace root:
+
+```json {% fileName="package.json" %}
+{
+  "devDependencies": {
+    "tailwindcss": "^4.0.0",
+    "@tailwindcss/vite": "^4.0.0"
+  }
+}
+```
+
+Configure your Vite setup:
+
+```typescript {% fileName="apps/shop/vite.config.ts" %}
+import { defineConfig } from 'vite';
+import react from '@vitejs/plugin-react';
+import tailwindcss from '@tailwindcss/vite';
+
+export default defineConfig({
+  plugins: [react(), tailwindcss()],
+  // ... rest of your config
+});
+```
+
+Add the import to your main CSS file:
+
+```css {% fileName="apps/shop/src/styles.css" %}
+@import 'tailwindcss';
+```
+
+## The NPM workspace challenge
+
+Consider a typical e-commerce application structured as an NPM workspace:
+
+```plain
+apps/
+  shop/
+    src                  <<<< where tailwind is configured
+packages/
+  products/
+    feat-product-list/
+    feat-product-detail/
+    data-access-products/
+  shared/
+    ui/
+    utils/
+```
+
+At this point, your application will build and serve, but you'll notice that styles from your `packages/` are missing. In this modular setup, your main application (`shop`) depends on various feature packages, but **Tailwind only scans the main app by default**. This means styles defined in your packages won't be included in the final bundle, leading to missing styles and broken layouts.
+
+## Solving the scanning problem with @source directives
+
+Tailwind v4 introduces the `@source` directive to address exactly this problem. You can explicitly tell Tailwind which directories to scan by adding these directives to your CSS file:
+
+```css {% fileName="apps/shop/src/styles.css" %}
+@import 'tailwindcss';
+
+@source "../../../packages/products/feat-product-list";
+@source "../../../packages/products/feat-product-detail";
+@source "../../../packages/shared/ui";
+...
+```
+
+With these directives in place, Tailwind will scan the specified packages and include any utility classes found there. Your application styles will now work correctly across all packages.
+
+## Automating @source entries - enter Nx sync generators
+
+While `@source` directives solve the technical problem, they introduce a maintenance challenge:
+
+- **manual updates required** when adding or removing dependencies,
+- **easy to forget updating** the directives,
+- **hard-to-debug issues** since missing styles don't break builds (just cause visual problems), and
+- **team coordination** since every developer needs to remember to update these paths.
+
+This is where automation becomes crucial and where Nx can help. [Nx Sync Generators](/concepts/sync-generators) provide a powerful solution for **automating configuration that needs to stay in sync with your project structure**.
+
+For our specific use case we can automate the generation of the `@source` directives by
+
+- analyzing and traversing all of the `shop` application's dependencies (leveraging the [Nx project graph](/features/explore-graph))
+- generating the `@source` entries into the correct `styles.css` file
+
+You can follow [the guide on the Nx docs](/extending-nx/recipes/create-sync-generator) for all the details on how to implement your own Nx sync generator. At a high level these are the steps you'll need:
+
+**Step 1: Add Nx Plugin development support**
+
+```shell
+npx nx add @nx/plugin
+```
+
+**Step 2: Generate a new plugin into your workspace**
+
+```shell
+npx nx g @nx/plugin:plugin tools/tailwind-sync-plugin
+```
+
+Note, you can choose whatever folder you like. I happen to use the `tools/` folder for this example.
+
+**Step 3: Generate a sync generator**
+
+```shell
+npx nx g @nx/plugin:generator --name=update-tailwind-globs --path=tools/tailwind-sync-plugin/src/generators/update-tailwind-globs
+```
+
+With that you have the infrastructure in place and we can look at the actual implementation of the sync generator:
+
+```typescript
+import { Tree, createProjectGraphAsync, joinPathFragments } from '@nx/devkit';
+import { SyncGeneratorResult } from 'nx/src/utils/sync-generators';
+
+export async function updateTailwindGlobsGenerator(
+  tree: Tree
+): Promise<SyncGeneratorResult> {
+  const appName = '@aishop/shop';
+  const projectGraph = await createProjectGraphAsync();
+
+  // Traverse all dependencies of the shop app
+  const dependencies = new Set<string>();
+  const queue = [appName];
+  const visited = new Set<string>();
+
+  while (queue.length > 0) {
+    const current = queue.shift()!;
+    if (visited.has(current)) continue;
+    visited.add(current);
+
+    const deps = projectGraph.dependencies[current] || [];
+    deps.forEach((dep) => {
+      dependencies.add(dep.target);
+      queue.push(dep.target);
+    });
+  }
+
+  // Generate @source directives for each dependency
+  const sourceDirectives: string[] = [];
+  dependencies.forEach((dep) => {
+    const project = projectGraph.nodes[dep];
+    if (project && project.data.root) {
+      const relativePath = joinPathFragments('../../../', project.data.root);
+      sourceDirectives.push(`@source "${relativePath}";`);
+    }
+  });
+
+  // Update the styles.css file
+  const stylesPath = 'apps/shop/src/styles.css';
+  const currentContent = tree.read(stylesPath)?.toString() || '';
+
+  // Insert the @source directives after @import "tailwindcss"
+  // ... (implementation details)
+
+  return {
+    outOfSyncMessage: 'Tailwind @source directives updated',
+  };
+}
+```
+
+_(Check out the [Github repo for the full implementation](https://github.com/juristr/tailwind4-vite-npm-workspaces))_
+
+You can manually run sync generators with `nx sync`, but we want this to run automatically whenever we build or serve our application. As such we can register the sync generator in the app's `package.json`:
+
+```json {% fileName="apps/shop/package.json" %}
+{
+  "name": "@aishop/shop",
+  ...
+  "nx": {
+    "targets": {
+      "build": {
+        "syncGenerators": ["@aishop/tailwind-sync-plugin:update-tailwind-globs"]
+      },
+      "serve": {
+        "syncGenerators": ["@aishop/tailwind-sync-plugin:update-tailwind-globs"]
+      }
+    }
+  }
+}
+```
+
+## Nx sync generators in action
+
+When you run your development server with `nx serve shop`, the sync generator automatically checks if your `@source` directives are up to date:
+
+![Tailwind Nx sync generator in action](/blog/images/articles/tailwind-sync-generator.avif)
+
+Your CSS file is automatically updated with the correct directives based on your actual project dependencies. If you add or remove dependencies later, the next build or serve will **detect the changes and update the configuration automatically**.
+
+You can find the complete implementation in this [GitHub repository](https://github.com/juristr/tailwind4-vite-npm-workspaces).
+
+## Using Tailwind v3?
+
+If you're currently using Tailwind v3, the concept is similar but the implementation differs. Instead of updating `@source` directives, you'd modify the `tailwind.config.js` file with glob patterns.
+
+Check out the following video which explains the same approach for Tailwind v3:
+
+{% youtube src="https://www.youtube.com/watch?v=huTmV-F8c0A" title="Optimizing Tailwind with Nx Sync Generators (v3)" /%}
+
+The [Tailwind v3 demo repository](https://github.com/juristr/tailwind-sync-demo) shows how to implement this approach for older versions.
+
+## Conclusion
+
+While Tailwind v4's simplified setup is a significant improvement, manually maintaining `@source` directives creates a maintenance burden in monorepos. Nx Sync Generators solve this by automatically keeping your Tailwind configuration in sync with your project dependencies, eliminating manual updates and preventing hard-to-debug styling issues.
+
+This approach transforms configuration maintenance into a completely automated process, letting you focus on building features rather than managing paths.
