Reactive forms is the best way to write forms in Angular. After a quick introduction to the reactive programming paradigm, I will share practical patterns and practices on how to develop forms, keeping ease of development and maintainability at the forefront. I will walk you through a multi-step form with varied inputs including reusable form groups, validations, date pickers, drop-downs with type-ahead support, form arrays, ngx-mask for input masking and implementing ControlValueAccessor.
