How do I configure fields in Angular Formly?

To configure fields in Angular Formly, you define a fields array in your component. Each field is an object that specifies its type, key, and other properties.

Can you give me an example of a text field configuration?

Sure! Here's a simple example:

fields: [
  {
    key: 'firstName',
    type: 'input',
    templateOptions: {
      label: 'First Name',
      placeholder: 'Enter your first name',
      required: true
    }
  }
]

What other field types can I use?

You can use various field types like 'input', 'textarea', 'select', 'checkbox', and even custom types. Each type has its own set of options.

How do I add validation to a field?

You can add validation by using the validators property in the field configuration. For example:

validators: {
  required: {
    expression: (c) => c.value.length > 0,
    message: 'This field is required'
  }
}
