Using a Custom Field



This is a beta version and subject to change without notice. Pricing, terms, conditions and availability may change in the final version.

  1. Open a Terminal or Command window and install the Iris App Runtime.
npm install @trackunit/iris-app-runtime-core
  1. Use the CustomFieldRuntime command to retrieve custom fields definitions and values saved to the specified Asset ID. If there are no saved values of the Asset ID, only the definition will be retrieved.
import { CustomFieldRuntime, CustomFieldType } from '@trackunit/iris-app-runtime-core';

// Get all custom field values and definitions for your asset ID.
const myCustomFieldsPromise = CustomFieldRuntime.getCustomFieldsFor({
  type: 'ASSET',
  id: '<my-asset-id>',
  1. Save the custom field value by entering a definition key, entity ID, and a new value.
// Save a custom field value
    type: 'ASSET',
    id: '<my-asset-id>',
      definitionKey: 'myKey',
      value: {
        type: CustomFieldType.STRING,
        stringValue: 'My new value',

React UI (User Interface) Components

Trackunit provides a React UI Component that renders a custom field input box according to a custom field definition.

npm install @trackunit/custom-field-components

See this complete example for how to use the component:

import React from 'react';
import {
} from '@trackunit/react-components';
import { CustomField } from '@trackunit/custom-field-components';
import { useForm } from 'react-hook-form';
import { useAssetRuntime, useCustomFieldRuntimeForEntity } from '@trackunit/react-core-hooks';

export const App: React.FC = () => {
  const { assetInfo } = useAssetRuntime();
  const { customFields, setCustomFieldsFromFormDataForEntity } = useCustomFieldRuntimeForEntity( {
    id: assetInfo?.assetId || '',
    type: 'ASSET'

  const { register, handleSubmit, formState, setValue } = useForm({
    shouldUnregister: false,

  // With the component it is possible to render an input component for any custom field by
  // providing a field retrieved from useCustomFieldRuntimeForEntity to the component.
  return (
        heading="Custom Fields"
        subHeading="Showcase for custom fields."
        {customFields?.map((field) => {
          return (
        <Button onClick={handleSubmit(setCustomFieldsFromFormDataForEntity)}>
