Angular Tailwind CSS Schematics

This schematic will add Tailwind CSS to your Angular application.

Versions

`@ngneat/tailwind`	AngularCLI
v7.x.x	>= 11.2.x
v6.x.x	>= v11.1.x, < 11.2.x
v5.2.5	< v11.1.x

v7.x.x

In v7, we leverage the built-in TailwindCSS support from AngularCLI if you use AngularCLI >= 11.2. When you invoke the schematics, and you have AngularCLI <11.2 installed, you'll see the following message:

Detected AngularCLI version is 11.0.7 which does not support TailwindCSS natively.
Please run "ng add @ngneat/tailwind@6" for Custom Webpack support.

v6.x.x

The main difference is Angular CLI v11.1+ uses PostCSS 8 already, so we remove that from our dependencies list. To use these schematics at specific version, please use this syntax: ng add @ngneat/tailwind@5.2.5 or npm i -D @ngneat/tailwind@5.2.5

Usage

ng add @ngneat/tailwind

Usage with Nx

IMPORTANT for AngularCLI users: As of April 06 2021, create-nx-workspace@latest still generates Angular with AngularCLI 11.0.7 which does not have built-in TailwindCSS support. Please update AngularCLI by running ng update @angular/cli before running this schematics.

In Nx, you can either use AngularCLI or NxCLI. If you set up your Nx Workspace to use AngularCLI, the usage is the same as above. If you set up your Nx Workspace with NxCLI, follow the steps:

Install @ngneat/tailwind first:

npm i -D @ngneat/tailwind tailwindcss postcss autoprefixer
yarn add -D @ngneat/tailwind tailwindcss postcss autoprefixer

then execute the schematics:

nx generate @ngneat/tailwind:nx-setup

Manual steps

v7.x.x

In v7, we do not use a Custom Webpack anymore. If you use Custom Webpack, please follow the below guide and use @ngneat/tailwind@6

v6.x.x

If your projects are already using a custom Webpack builder with a custom webpack.config, follow these steps to add TailwindCSS to your project

npm i -D @ngneat/tailwind tailwindcss (or yarn add -D @ngneat/tailwind tailwindcss)
Import addTailwindPlugin from @ngneat/tailwind in your webpack.config
Import your TailwindCSS config in your webpack.config
Before you return or modify the original Webpack config, call addTailwindPlugin with the following parameters:
- webpackConfig: the Webpack config
- tailwindConfig: the TailwindCSS config that you import
- patchComponentsStyles?: this flag will enable using TailwindCSS directives in components' stylesheets. Default to false because turning it on might impact your build time

// example
const { addTailwindPlugin } = require('@ngneat/tailwind');
const tailwindConfig = require('relative/path/to/tailwind.config');

module.exports = (config) => {
  addTailwindPlugin({
    webpackConfig: config,
    tailwindConfig,
    patchComponentsStyles: true,
  });
  return config;
};

Angular Material

If you plan to use @ngneat/tailwind with @angular/material, please make sure that you setup @angular/material before @ngneat/tailwind because @angular/material:ng-add schematics will error out if it detects a custom Webpack in your angular.json.

Purge

@ngneat/tailwind uses built-in purge functionality by tailwindcss (under the hood, it is postcss-purgecss). By default, @ngneat/tailwind sets the content to any HTML and any TS files in the project.

This behavior can be modified as the consumers see fit.

Tailwind JIT (v7.x.x only)

In v7, @ngneat/tailwind provides an option to enable JIT mode for TailwindCSS. This is a new compilation mode that improves the compilation time as it does not compile ALL of TailwindCSS anymore but only compiles what you use in your application. This mode is still in preview as of tailwindcss@2.1.1

CSS Preprocessors

If you're using CSS Preprocessors (SASS/SCSS, LESS, Stylus) in your application, please check out TailwindCSS's Using with Preprocessors guide

Commit

Run git add . to stage your changes
Run npm run commit to start Conventional Commit flow

Commit Hooks

pre-commit will execute npm run lint and pretty-quick to lint and reformat.pre-commit does not run Unit Tests because Unit Tests will be ran in Github Actions. Feel free to run the Unit Tests with npm run test to test your changes

E2E Tests

Please run npm run e2e to run E2E tests before pushing

Updating README

README is in two places at the moment: root and libs/tailwind/README.md. The one in root is the one displayed on Github while the one in libs/tailwind is being used on npm. When you make changes to README, make sure to update both.

A script can be created to automating this.

PR

When everything passes and looks good, make a PR. Thanks for your contribution.
