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

Overview

Data Transformer Array-map is an Angular Service that executes another Data Transformer based on the config for every element in the array.

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

Service configuration:

  • mapItems—a Data Transformer that is set up with a configuration object.
<spy-select
    [datasource]="{
        type: 'inline',
        data: [
            {
                type: 'date',
                date: '2020-09-24T15:20:08+02:00',
            },
            {
                type: 'date',
                date: '2020-09-24T15:20:08+02:00',
            },
        ],
        transform: {
            type: 'array-map',
            mapItems: {
                type: 'lens',
                path: 'date',
                transformer: {
                    type: 'date-parse',
                },
            },
        },
    }"
