Overview

The challenge

Users should be able to:

• Complete each step of the sequence
• Go back to a previous step to update their selections
• See a summary of their selections on the final step and confirm their order
• View the optimal layout for the interface depending on their device's screen size
• See hover and focus states for all interactive elements on the page
• Receive form validation messages if:
  • A field has been missed
  • The email address is not formatted correctly
  • A step is submitted, but no selection has been made

What I learned

This chanllenge gave me an opportunity to try out the latest Angular features:

• Strictly typed reactive forms

type MultiStepForm = {
  info: FormGroup<InfoGroup>;
  plan: FormGroup<PlanGroup>;
  addOns: FormGroup<AddOnsGroup>;
};

• Angular Signals

  • inputs
  • outputs
  • model inputs
  • view queries

Useful resources

• Strongly Typed Reactive Forms in Angular - This is an amazing article that inspired me to start experimenting with strictly typed reactive forms in the first place and led me to take up this challenge.
• Component Communication with Signals: Inputs, Two-Way Bindings, and Content/ View Queries - This guide was extremely helpful in understanding how to handle Signal-based property bindings. I highly recommend it to anyone still learning this concept.
