Tailwind CSS is a popular utility-first CSS framework that can be used with Angular projects to create responsive and customizable UI components. It's a game-changer for developers who want to build fast and maintainable applications.

One of the main benefits of using Tailwind CSS with Angular is that it allows you to write more concise and readable CSS code. As we'll see in the next section, Tailwind's pre-defined utility classes make it easy to style components without having to write custom CSS.

With Tailwind CSS, you can create custom layouts and designs without having to worry about the underlying CSS implementation. This is especially useful for Angular developers who want to focus on building features rather than writing CSS from scratch.

Angular Project Setup

To set up a new Angular project with Tailwind CSS, you can use the Nx CLI with the command `npx nx g @nx/angular:app apps/my-app --add-tailwind`. This will generate an Angular application with Tailwind CSS configured.

You can also use the `ng new` command to create a new Angular application, as shown in the example `ng new tailwind-navbar`. This will create a starter application for Angular.

To add Tailwind CSS to an existing Angular application, you can run the command `npx nx g @nx/angular:setup-tailwind my-project`. This will add Tailwind CSS to your project.

Setup

To generate an Angular application with Tailwind CSS configured, run `npx nx g @nx/angular:app apps/my-app --add-tailwind`. This will get you started with a new Angular app and Tailwind CSS already set up.

You can also generate an Angular buildable library with Tailwind CSS configured using `npx nx g @nx/angular:lib libs/my-lib --buildable --add-tailwind`. This will create a library that can be built and used in your project.

Setting up Tailwind with Angular v12 involves running a simple command to install Tailwind and its dependencies. This is the first step in getting Tailwind up and running in your Angular project.

To install Tailwind and its dependencies, run the command as described in the official documentation. This will ensure you have all the necessary tools to work with Tailwind in your Angular project.

You can also create a new Angular application using the `ng new` command, as shown in the example `ng new tailwind-navbar`. This will create a new Angular project with a basic setup.

To add Tailwind CSS to an existing Angular application, buildable library, or publishable library, run `npx nx g @nx/angular:setup-tailwind my-project`. This will add Tailwind CSS support to your project.

By following these steps, you can get Tailwind CSS up and running in your Angular project. Remember to check the official documentation for more information on each of these steps.

Configuring Content Sources for a Project

Configuring content sources for your Angular project can be a bit tricky, especially when it comes to dependencies. Tailwind CSS scans files for class names to generate only the necessary CSS, but you need to configure which files should be processed.

To do this, you can use the `content` property in your `tailwind.config.js` file. This property usually consists of a glob pattern that includes all the necessary files.

In an Nx workspace, it's common for a project to have other projects as dependencies. Setting and updating the glob to reflect those dependencies and their files can be cumbersome and error-prone.

Nx has a utility function called `createGlobPatternsForDependencies` that can help with this. It constructs the glob representation of all files a project depends on based on the Nx Project Graph.

Here's an example of how to use this function:

```javascript

const globPatterns = createGlobPatternsForDependencies(__dirname);

```

This will identify the project and obtain its dependencies from the project graph, creating the glob patterns for each dependency.

If your project has dependencies like `lib1` and `lib2`, the utility function will return the following glob patterns:

  • `lib1/src/**/*.ts`
  • `lib1/src/**/*.html`
  • `lib2/src/**/*.ts`
  • `lib2/src/**/*.html`

By using this utility function, you can easily configure the content sources for your project and its dependencies.

In a Module Federation setup, Tailwind starts scanning files at the host application, but only includes direct dependencies of that application. To fix this, you can add an implicit dependency between the host application and the remote applications, or add a path to the `content` array to include the remote application and its dependencies.

Configuring Content

Configuring content is a crucial step in using Tailwind CSS with Angular.

To configure which files should be processed, you can use the `content` property in your `tailwind.config.js` file. This property usually consists of a glob pattern to include all necessary files.

Nx provides a utility function called `createGlobPatternsForDependencies` that can be used to construct the glob representation of all files a project depends on. This function receives a directory path to identify the project and can also receive an optional glob pattern to append to each dependency source root path.

The `createGlobPatternsForDependencies` function can be used in an Nx workspace to construct glob patterns for dependencies. For example, in an application called `app1`, you can use this function to obtain its dependencies from the project graph.

The function will return an array of glob patterns for each dependency. For instance, if `app1` has `lib1` and `lib2` as dependencies, the utility function will return the following glob patterns:

  • `lib1/src/**/*.ts`
  • `lib1/src/**/*.html`
  • `lib2/src/**/*.ts`
  • `lib2/src/**/*.html`

If you're using Tailwind with Module Federation, you may need to include remote applications and their dependencies in your `content` array. This can be done by adding a path to the `content` array to include the remote application and its dependencies.

Distribute Themes

To build and share a theme, you can create a theme file in the library. This file should provide the CSS for its components so they can be used by applications consuming them.

You need to configure your project to build the theme when you build the library. Edit the project configuration to have the following targets:

You're configuring the library build and the Tailwind CSS processing to happen in parallel. Also, you're disabling the automatic deletion of the output folder that ng-packagr does because that can cause the theme to be deleted.

Update the libs/lib1/ng-package.json file to set the deleteDestPath property to false. This will prevent the output folder from being deleted during the library build.

If you use the default Tailwind CSS utility classes and distribute your theme with them, there can be conflicts with consumer applications that also use Tailwind CSS. To avoid this, you have a couple of options:

  • Add a unique prefix to your Tailwind CSS utility classes.
  • Create unique CSS classes for your components and theme in general using a Tailwind CSS directive like @apply or a function like theme().

If you decide to use a unique prefix, remember to change the utility classes used in your components to use the prefix.

Creating the Application

To start with Tailwind CSS and Angular, you'll first need to create a new Angular application.

You can use the ng new command to get started, specifying the application name, in this case, tailwind-navbar.

This command will create a starter application to get you started with Angular.

The version of Angular used in this tutorial is 17.1.3.
