Amplience Dynamic Content

dc-extensions-sdk

Build Status npm version

An SDK that enables the creation of Extensions for Dynamic Content. Extensions are custom form controls that can be used in the content editing form in the Dynamic Content App.

Installation

Using npm:

npm install dc-extensions-sdk --save

Using yarn:

yarn add dc-extensions-sdk

Using cdn:

<script src="https://unpkg.com/dc-extensions-sdk/dist/dc-extensions-sdk.umd.js"></script>

Usage

Creating a vanilla Javascript extension

import { init } from 'dc-extensions-sdk';

async function initialize() {
  const sdk = await init();
}

initialize();

or

const dcExtensionsSdk = require('dc-extensions-sdk');

async function initialize() {
  const sdk = await dcExtensionsSdk.init();
}

initialize();

Creating a typed Content Field extensions with Typescript

import { init } from 'dc-extensions-sdk';
import type { ContentFieldExtension } from 'dc-extensions-sdk';

// define the input field model
interface FieldModel {
  title: string;
  type: string;
  control: string;
  format: string;
  minLength: number;
  maxLength: number;
}

// define the installation config parameters
interface Parameters {
  instance: {};
  installation: {
    configParam: string;
  };
}

async function initialize() {
  const sdk = await init<ContentFieldExtension<FieldModel, Parameters>>();
}

initialize();

Creating a typed Dashboard extensions with Typescript

import { init } from 'dc-extensions-sdk';
import type { DashboardExtension } from 'dc-extensions-sdk';

// define the installation config parameters
interface Parameters {
  instance: {};
  installation: {
    configParam: string;
  };
}

async function initialize() {
  const sdk = await init<DashboardExtension<Parameters>>();
}

initialize();

Options

You can configure your extension with the options object passed into the init function.

import { init } from 'dc-extensions-sdk';

const options = {
  // enable useful behind-the-scenes info
  debug: false,
  // the max time to wait for a connection to establish
  connectionTimeout: 4500,
};

async function initialize() {
  const sdk = await init(options);

  //..
}

initialize();

Content Field Usage

Field

Fetching the field value

const fieldValue = await sdk.field.getValue();

console.log(fieldValue);

Setting the field value

Note: The field model isn't updated when the form is in a read only state.

const sdk = await init();

await sdk.field.setValue('some value');

Resetting the field value

This will reset to the previously saved state or undefined if the item hasn't been saved.

const sdk = await init();

await sdk.field.resetValue();

Retrieving the field schema

const sdk = await init();

const schema = sdk.field.schema;

Test if a model is valid

Will evaluate the supplied model against the schema. Returns a boolean.

const sdk = await init();

const isValid = await sdk.field.isValid('some value');

Test if a model is valid (with errors)

Will evaluate the supplied model against the schema. Will either return an array of errors or undefined.

const sdk = await init();

const errors = await sdk.field.validate('some value');

Content Item

Use to fetch the Content Item that is currently being edited.

const sdk = await init();

const contentItem = await sdk.contentItem.getCurrent();

Example Content Item:

{
  "id": "4801f662-de68-43d3-8864-52d2d9c10bf4",
  "deliveryId": "4801f662-de68-43d3-8864-52d2d9c10bf4",
  "locale": "en-GB",
  "body": {
    "_meta": {
      "name": "hello-world",
      "schema": "http://www.hello-world.com"
    },
    "helloWorld": "Test"
  },
  "label": "Hello World",
  "version": 8
}

Frame

Setting the height

This changes the height of the extension. It will measure the height of the application and change the container's height to fit. You can also force a height by specifying an integer value.

const sdk = await init();

sdk.frame.setHeight(); // measures height
sdk.frame.setHeight(300); // override height

Auto Resizing

While the application's height will be automatically set on load, your application's size might change over time. When this happens you can either trigger sdk.frame.setHeight(); or use the Auto Resizer.

The Auto Resizer will listen for any change to the DOM as well as window resizing. When it is triggered it will automatically resize the container’s height to the size of the extension.

NOTE: If your application dynamically loads images we suggest you attach a load event listener that will trigger sdk.frame.setHeight();

const sdk = await init();
// turn on the Auto Resizer
sdk.frame.startAutoResizer();

// turn off the Auto Resizer
sdk.frame.stopAutoResizer();

Locales

The available locales for the Content Item.

const sdk = await init();

const locales = sdk.locales;

console.log(locales);

Example:

{
  "default": ["en-GB", "fr-FR"],
  "available": [
    {
      "locale": "en-GB",
      "language": "en",
      "country": "GB",
      "index": 0,
      "selected": true
    },
    {
      "locale": "fr-FR",
      "language": "fr",
      "country": "FR",
      "index": 1,
      "selected": false
    }
  ]
}

Params

These allow your component to be configurable. They can be defined in the JSON Schema (instance) or defined in the registry (installation), or both.

const sdk = await init();

console.log(sdk.params);
{
  instance: {},
  installation: {}
}

Media Link

Use this to trigger an image or video browser.

const sdk = await init();

const image = await sdk.mediaLink.getImage();
const video = await sdk.mediaLink.getVideo();

Content Link

Use this to trigger an content-item browser for including content-links. Include a list of schemas to browse for.

const sdk = await init();

const contentLink = await sdk.contentLink.get(['http://my.schema/carousel.json']);

Content Reference

Use this to trigger an content-item browser for including content references. Include a list of schemas to browse for.

const sdk = await init();

const contentReference = await sdk.contentReference.get(['http://my.schema/carousel.json']);

Form

Model

Use this to fetch the in-progress form model. This can change while the extension is open.

const sdk = await init();

const formModel = await sdk.form.getValue();

Read Only

In some contexts in the form content is not editable and we provide a boolean value that specifies if content should not be editable if you want to react to these changes we give you a function to do so.

Note: The field model isn't updated when the form is in a read only state.

const input = document.querySelector('input');
const sdk = await init();

// the state is set on load of the form
console.log(sdk.form.readOnly);

sdk.form.onReadOnlyChange((readOnly) => {
  if (readOnly) {
    input.setAttribute('disabled', true);
  } else {
    input.removeAttribute('disabled');
  }
});

Dashboard

Application Navigator

The ApplicationNavigator is exposed on the Dashboard extension under the property applicationNavigator.

For each of the open commands you can supply an additional options argument if you wish to only return the href. This maybe useful if you need to set the href directly on an anchor within your extension.

const sdk = await init();
const href = sdk.applicationNavigator.openEventsCalendar({ returnHref: true });

const anchor = window.document.getElementById('my-anchor');
anchor.setAttribute('href', href);

Open the events calendar

const sdk = await init();
sdk.applicationNavigator.openEventsCalendar();

Open the events timeline

const sdk = await init();
sdk.applicationNavigator.openEventsTimeline();

Open the events list

const sdk = await init();
sdk.applicationNavigator.openEventsList();

Open an event by id

const sdk = await init();
sdk.applicationNavigator.openEvent({ id: 'EVENT_ID...' });

Open edition by edition id & event id

const sdk = await init();
sdk.applicationNavigator.openEdition({ id: 'EDITION_ID...', eventId: 'EVENT_ID...' });

Open the content Library

const sdk = await init();
sdk.applicationNavigator.openContentLibrary();

Open a content item by id

const sdk = await init();
sdk.applicationNavigator.openContentItem({ id: 'CONTENT_ITEM_ID...' });

Client (Supported on Content Field & Dashboard extensions)

Use client with dc-management-sdk-js

import { init } from 'dc-extensions-sdk';
import { DynamicContent } from 'dc-management-sdk-js';

const dcExtension = await init();
const dcManagement = new DynamicContent({}, {}, dcExtension.client);

const hubs = await dcManagement.hubs.list();

Users (Supported on Content Field & Dashboard extensions)

Return users logged in to the Content Management application

import { init } from 'dc-extensions-sdk';

const dcExtension = await init();

const users = await dcExtension.users.list();
console.log(users);

Example:

[
  {
    id: '7078e5e7-d5bf-4015-4832-b75fb6f60537',
    firstName: 'Test',
    lastName: 'User',
    email: 'testuser@bigcontent.io',
  }
]
