Implementation

import { Component } from '@angular/core';
import { DynamicForm, FormConfig } from '@ng-forge/dynamic-forms';

@Component({
  selector: 'app-login-form',
  imports: [DynamicForm],
  template: `<form [dynamic-form]="config"></form>`,
})
export class LoginFormComponent {
  config = {
    // Define common validation messages at the form level
    defaultValidationMessages: {
      required: 'This field is required',
      minLength: 'Must be at least  characters',
    },
    fields: [
      {
        key: 'title',
        type: 'text',
        label: 'Sign In',
        props: {
          elementType: 'h2',
        },
      },
      {
        key: 'email',
        type: 'input',
        label: 'Email Address',
        required: true,
        email: true,
        // Only specify custom message for 'email' - 'required' uses default
        validationMessages: {
          email: 'Please enter a valid email address',
        },
        props: {
          type: 'email',
          placeholder: 'your@email.com',
          hint: 'Enter the email associated with your account',
        },
      },
      {
        key: 'password',
        type: 'input',
        label: 'Password',
        required: true,
        minLength: 8,
        // Override default 'required' message with custom one
        validationMessages: {
          required: 'Password is required',
        },
        // 'minLength' will use default with interpolated 
        props: {
          type: 'password',
          placeholder: 'Enter your password',
        },
      },
      {
        key: 'remember',
        type: 'checkbox',
        label: 'Remember me for 30 days',
      },
      {
        type: 'submit',
        key: 'submit',
        label: 'Sign In',
        props: {
          color: 'primary',
        },
      },
    ],
  } as const satisfies FormConfig;
}

Key Features

Email Validation

Built-in email format validation:

{
  key: 'email',
  email: true,  // Validates email format
  validationMessages: {
    email: 'Please enter a valid email',
  },
}

Password Security

Minimum length requirement and masked input:

{
  key: 'password',
  minLength: 8,
  props: {
    type: 'password',  // Masks input
  },
}

Remember Me Option

Simple checkbox for persistent login:

{
  key: 'remember',
  type: 'checkbox',
  label: 'Remember me',
}

Common Enhancements

Add "Forgot Password" Link

{
  type: 'text',
  key: 'forgotLink',
  label: '<a href="/forgot-password">Forgot your password?</a>',
}

For social login buttons, you can use text fields with links or handle this outside the form:

{
  type: 'text',
  key: 'socialText',
  label: 'Or sign in with Google or GitHub',
}

Note: Social login typically involves OAuth flows handled outside the form. Consider placing social login buttons in your component template rather than in the form configuration.

{
  type: 'text',
  key: 'signupText',
  label: "Don't have an account? <a href='/signup'>Sign up</a>",
}
