Data Transformer: Object-map

Edit on GitHub

This document explains the Data Transformer Object-map service in the Components Library.


Data Transformer Object-map is an Angular Service that executes another Data Transformer from the config for specific properties in an object.

In the following example, the datasource will return an array with the transformed date in every child object.

Service configuration:

  • mapProps—a Data Transformer that is set up with a configuration object.
  • propName—the name of the property from which the value needs to be transformed.
        type: 'inline',
        data: [
                  type: 'date',
                  date: '2020-09-24T15:20:08+02:00',
                  type: 'date',
                  date: '2020-09-22T15:20:08+02:00',
        transform: {
            type: 'array-map',
            mapItems: {
                type: 'object-map',
                mapProps: {
                    date: {
                        type: 'date-parse',

Service registration

Register the service:

declare module '@spryker/data-transformer' {
    interface DataTransformerRegistry {
        'object-map': ObjectMapDataTransformerConfig;

    imports: [
            'object-map': ObjectMapDataTransformerService,
export class RootModule {}


Below you can find interfaces for the Data Transformer Object-map:

export interface ObjectMapDataTransformerConfig extends DataTransformerConfig {
    mapProps: {
        [propName: string]: DataTransformerConfig;
