This code is part of the my article Creating Dynamic Forms in Angular: A Step-by-Step Guide. In the guide, I explain how to create a dynamic form using Angular 21 and Reactive Forms, starting from a simple scenario to other cases suggested by the community.

• Dynamic form generation based on JSON configuration
• Support for various input types (Text, Number, Date, Radio, Checkbox, Select)
• Validation integration
• Updated to Angular 21
• Fully standalone components architecture (no NgModules)
• Modern Signal Forms APIs - Using input() signals and reactive effects

• Node.js (Latest LTS version recommended)
• npm or yarn

1. Clone the repository:

   git clone https://github.com/danywalls/dynamic-forms.git

2. Navigate to the project directory:

   cd dynamic-forms

3. Install dependencies:

   npm install

Run the development server:

npm start

Navigate to http://localhost:4200/. The application will automatically reload if you change any of the source files.

Run the unit tests with Vitest:

npm test

This project uses Vitest and Angular Testing Library for fast and reliable unit testing.

I want to say thanks to everyone who voted a star and helped to improve this article to help other developers solve a common task for every Angular developer.
