Installation

Install the bundle & initialize your app with two commands:

1
2

$ composer require symfonycasts/tailwind-bundle
$ php bin/console tailwind:init

Done! This will create a tailwind.config.js file and make sure your assets/styles/app.css contains the Tailwind directives.

Usage

To use the Tailwind CSS file, start by including the input file (assets/styles/app.css by default) in base.html.twig. It's quite likely you already have this:

1
2
3
4
5

{# templates/base.html.twig #}

{% block stylesheets %}
    <link rel="stylesheet" href="{{ asset('styles/app.css') }}">
{% endblock %}

The bundle works by swapping out the contents of styles/app.css with the compiled CSS automatically. For this to work, you need to run the tailwind:build command:

1

$ php bin/console tailwind:build --watch

That's it! This will watch for changes to your assets/styles/app.css file and automatically recompile it when needed. If you refresh the page, the final app.css file will already contain the compiled CSS.

How Does It Work?

The first time you run one of the Tailwind commands, the bundle will download the correct Tailwind binary for your system into a var/tailwind/ directory.

When you run tailwind:build, that binary is used to compile your CSS file into a var/tailwind/tailwind.built.css file. Finally, when the contents of assets/styles/app.css is requested, the bundle swaps the contents of that file with the contents of var/tailwind/tailwind.built.css. Nice!

Deploying

When you deploy, run the tailwind:build command before the asset-map:compile command so the built file is available:

1
2

$ php bin/console tailwind:build --minify
$ php bin/console asset-map:compile

Configuration

To see the full config from this bundle, run:

1

$ php bin/console config:dump symfonycasts_tailwind

The main option is input_css option, which defaults to assets/styles/app.css. This represents the "source" Tailwind file (the one that contains the @tailwind directives):

1
2
3

# config/packages/symfonycasts_tailwind.yaml
symfonycasts_tailwind:
    input_css: 'assets/styles/other.css'

Using a Different Binary

The standalone Tailwind binary comes with the first-party plugins. However, if you want to add extra plugins, you may choose to install Tailwind via npm instead:

1

$ npm add tailwindcss

To instruct the bundle to use that binary instead, set the binary option:

1
2
3

# config/packages/symfonycasts_tailwind.yaml
symfonycasts_tailwind:
    binary: 'node_modules/.bin/tailwindcss'
