[CoalesceMetadata]

IntelliTect.Coalesce.DataAnnotations.CoalesceMetadataAttribute

Placed on an assembly, specifies an attribute type whose values should be extracted from any Coalesce-generated types, properties, methods, and parameters, and emitted into the generated TypeScript metadata.

The extracted attribute values are available in the attributes property of the corresponding metadata object in metadata.g.ts.

Example Usage

Register the attribute type at the assembly level in your data project (e.g. in any .cs file):

[assembly: CoalesceMetadata<System.ComponentModel.CategoryAttribute>]

Then use the attribute on your models:

[Category("people")]
public class Person
{
    [Category("contact")]
    public string? Email { get; set; }

    [Category("contact")]
    public string? Phone { get; set; }

    [return: Category("action")]
    public ItemResult ChangeSpaces(string newSpaces) { ... }
}

Properties

Type AttributeType

The attribute type whose values should be extracted and emitted into metadata. All constructor arguments and explicitly-set named properties on the attribute will be included.

string? Key

The key name to use in the generated metadata. If not specified, the attribute type name is used with the Attribute suffix removed and camelCased (e.g. FeatureFlagAttribute → featureFlag).

Output Format

• Parameterless attributes: Emitted as an empty object {}.
• All other attributes: Emitted as an object with camelCased property names.

Supported value types include strings, numbers, booleans, enums (emitted as their string representation), and arrays of these types.

TypeScript Type

The attributes property is available on all metadata interfaces:

readonly attributes?: {
  readonly [key: string]: { readonly [key: string]: unknown }
}
