Tailwind CSS Configuration

This library does not import Tailwind CSS directly. You must configure Tailwind in your application.

1. Configure Content Paths

Add the library's component templates to your Tailwind content configuration so the PostCSS parser can detect the utility classes used:

For Tailwind CSS 4+ (CSS-based config):

/* app.css or styles.css */
@import "tailwindcss";

@source "../node_modules/@pegasus-heavy/ngx-tailwindcss/**/*.{js,mjs}";

For Tailwind CSS 3.x (tailwind.config.js):

// tailwind.config.js
module.exports = {
  content: [
    "./src/**/*.{html,ts}",
    "./node_modules/@pegasus-heavy/ngx-tailwindcss/**/*.{js,mjs}",
  ],
  // ... rest of your config
};

2. Import Components

Import components directly in your Angular components:

import { Component } from '@angular/core';
import {
  TwButtonComponent,
  TwCardComponent,
  TwCardBodyDirective
} from '@pegasus-heavy/ngx-tailwindcss';

@Component({
  selector: 'app-example',
  standalone: true,
  imports: [TwButtonComponent, TwCardComponent, TwCardBodyDirective],
  template: `
    <tw-card>
      <tw-card-body>
        <tw-button variant="primary">Click me!</tw-button>
      </tw-card-body>
    </tw-card>
  `,
})
export class ExampleComponent {}

Or import everything at once:

import { TW_ALL } from '@pegasus-heavy/ngx-tailwindcss';

@Component({
  imports: [...TW_ALL],
})
export class ExampleComponent {}

Global Configuration

Customize default styles and behavior globally:

// app.config.ts
import { ApplicationConfig } from '@angular/core';
import { provideTwConfig } from '@pegasus-heavy/ngx-tailwindcss';

export const appConfig: ApplicationConfig = {
  providers: [
    provideTwConfig({
      theme: {
        primary: 'bg-indigo-600 hover:bg-indigo-700 text-white',
        secondary: 'bg-purple-600 hover:bg-purple-700 text-white',
        // ... customize other variants
      },
      animationDuration: 300,
    }),
  ],
};
