Angular Forms In Depth (Angular 20)

Why take this course?
🚀 Angular Forms In Depth (Angular 17) 📚
Course Headline: Build complex enterprise data forms with the powerful Angular 17 Forms module.
Introduction to the Course
This course is an in-depth guide to Angular's template-driven and reactive forms, equipped with a comprehensive Github repository for hands-on practice. 🧰
Why This Course?
Angular applications, particularly those built for enterprise use, often require sophisticated data entry forms. These can range from simple forms to complex ones with extensive validation logic. Angular's Forms module is the solution to building these forms efficiently and effectively. With its two main types of forms—template-driven and reactive—Angular empowers developers to create scalable and user-friendly interfaces for data entry.
Course Overview
We'll kick off the course by creating a simple form using template-driven forms with ngModel
. We'll dive deep into understanding how ngModel
and ngForm
work behind the scenes and explore various ways to use these directives for data binding and form validation. 🛠️
As we progress, we'll cover:
- Template-Driven Forms: A detailed walkthrough on building custom form validators using custom directives and understanding the nuances of
ngModelOptions
. - Refactoring: Transforming our template-driven form into a reactive form to compare both approaches.
- Reactive Forms: Leveraging the powerful features of reactive forms to construct a multi-step, complex data entry form with nested groups, arrays of controls, custom validators, and much more.
- Angular Material Form Components: Integrating ready-to-use form elements provided by Angular Material for a polished UI experience.
- File Upload: Building a custom file upload control that includes progress indicators and the ability to cancel uploads.
