Angular & Signals (283 Qs)•Part 10: Reactive Forms, Standalone Components, Signals & NgRx (256 - 283)
What are dynamic forms?
Dynamic forms is a pattern in which we build a form dynamically based on metadata that describes a business object model. You can create them based on reactive form API.
Practical Code Example
typescript
// Dynamic Forms: Generating FormControls dynamically from configuration:
const formControls = fields.reduce((acc, field) => {
acc[field.key] = new FormControl(field.defaultValue || '', Validators.required);
return acc;
}, {} as any);
const dynamicForm = new FormGroup(formControls);
