Using Panda CSS with Angular

Setting up Panda CSS in a Angular project using PostCSS.

Start a new project

Create Vite project

To get started, we will need to create a new Angular project using the official scaffolding tool (opens in a new tab).

If you don't enter any parameter, the CLI will guide you through the process of creating a new Angular app.

ng new test-app

You will be asked a few questions, answer them as follows:

? Which stylesheet format would you like to use? CSS
? Do you want to enable Server-Side Rendering (SSR) and Static Site Generation (SSG/Prerendering)? No

Install Panda

Install panda and create your panda.config.ts file.

pnpm install -D @pandacss/dev
pnpm panda init

npm install -D @pandacss/dev
npx panda init

yarn add -D @pandacss/dev
yarn panda init

bun add -D @pandacss/dev
bun panda init

Configure PostCSS

Create a postcss.config.json file in the root of your project and add the following code:

postcss.config.json

{
  "plugins": {
    "@pandacss/dev/postcss": {}
  }
}

💡

You must use a JSON file for the PostCSS configuration, as the Angular CLI does not support JavaScript PostCSS configuration files.

Update package.json scripts

Open your package.json file and update the scripts section as follows:

package.json

{
  "scripts": {
+    "prepare": "panda codegen",
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
  }
}

"prepare" - script that will run Panda CSS CLI codegen before each build. Read more about codegen in the CLI section.

💡

This step ensures that the panda output directory is regenerated after each dependency installation. So you can add the output directory to your .gitignore file and not worry about it.

Configure the content

Make sure that all of the paths of your Angular components are included in the include section of the panda.config.ts file.

panda.config.ts

import { defineConfig } from "@pandacss/dev"
 
export default defineConfig({
 // Whether to use css reset
 preflight: true,
 
 // Where to look for your css declarations
 include: ['./src/**/*.{js,jsx,ts,tsx}'],
 
 // Files to exclude
 exclude: [],
 
 // The output directory for your css system
 outdir: "styled-system",
})

Configure the entry CSS with layers

Add this code to an src/index.css file and import it in the root component of your project.

src/index.css

@layer reset, base, tokens, recipes, utilities;

Start your build process

Run the following command to start your development server.

pnpm dev

npm run dev

yarn dev

bun dev

Start using Panda

Now you can start using Panda CSS in your project. Here is the snippet of code that you can use in your src/app.component.ts file.

src/app.component.ts

import { Component } from '@angular/core';
import { css } from '../styled-system/css';
 
@Component({
  selector: 'app-root',
  standalone: true,
  template: `
    <div [class]="redBg"></div>
  `,
})
export class App {
  redBg = css({ bg: 'red.400' });
}
