Usage

Creating a vanilla Javascript extension

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

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

initialize();
`

or

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

}

initialize();
`

Creating a typed Content Field extension with Typescript

`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>();
}

initialize();
`

Creating a typed Dashboard extension with Typescript

`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>();
}

initialize();
`

Creating a typed Content Editor extension with Typescript

`typescript
import { init } from 'dc-extensions-sdk';
import type { ContentEditorExtension } from 'dc-extensions-sdk';

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

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

initialize();
`

Options

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

`js
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

$3

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

console.log(fieldValue);
`

$3

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

`js
const sdk = await init();

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

$3

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

`js
const sdk = await init();

await sdk.field.resetValue();
`

$3

`js
const sdk = await init();

const schema = sdk.field.schema;
`

$3

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

`js
const sdk = await init();

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

$3

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

`js
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.

`js
const sdk = await init();

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

Example Content Item:

`json
{
"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
}
`

Assets

Use to get assets.

`js
const sdk await init();

const asset = await sdk.assets.getById('123-456-789');
`

Example asset:

`json
{
"srcName": "an-image.jpg",
"revisionNumber": 8,
"bucketID": "00000000-0000-0000-0000-000000000000",
"label": "an-image.jpg",
"mimeType": "image/jpeg",
"type": "image",
"userID": "00000000-0000-0000-0000-000000000000",
"thumbFile": "00000000-0000-0000-0000-000000000000",
"folderID": "00000000-0000-0000-0000-000000000000",
"file": "00000000-0000-0000-0000-000000000000",
"createdDate": 1683798022161,
"name": "an-image",
"subType": null,
"id": "00000000-0000-0000-0000-000000000000",
"thumbURL": "https://thumbs.amplience.net/r/00000000-0000-0000-0000-000000000000",
"publishStatus": "PUBLISHED",
"status": "active",
"timestamp": 1688563779803
}
`

Frame

$3

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.

`js
const sdk = await init();

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

$3

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();_

`js
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.

`js
const sdk = await init();

const locales = sdk.locales;

console.log(locales);
`

Example:

`json
{
"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.

`js
const sdk = await init();

console.log(sdk.params);
`

`js
{
instance: {},
installation: {}
}
`

Media Link

Use this to trigger an image or video browser.

`js
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.

`js
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.

`js
const sdk = await init();

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

Form

$3

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

`js
const sdk = await init();

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

$3

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._

`js
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.

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

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

$3

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

$3

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

$3

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

$3

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

$3

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

$3

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

$3

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

Content Editor

$3

Fetching will give you the current model of the content item you're viewing.

`js
const sdk = await init();
const model = await sdk.form.getValue();
`

$3

Setting the model will return Error Report if there is any invalid content

`js
const sdk = await init();
try {
await sdk.form.setValue({ title: 'hello world' });
} catch (errors) {
if (errors.length) {
console.log(errors);
}
}
`

$3

You can validate an object against the schema and get the full error report back

`js
const sdk = await init();
const errors = await sdk.form.validate({
title: 'hello world',
});

if (errors) {
console.log(errors);
}
`

Example:

`
[
{
errorCategory: 'DATA',
errorData: {
keyword: 'maxLength',
params: {
limit: 10,
},
},
errorSeverity: 'FATAL',
errorType: 'DATA_VALIDATION_ERROR',
message: 'should NOT be longer than 10 characters',
schema: {
id: 'https://simple-text.com',
originalId: 'https://simple-text.com',
location: {
pointer: '/properties/title/maxLength',
},
},
data: {
location: {
pointer: '/title',
},
},
},
];
`

$3

A boolean value is returned showing whether the content is valid

`js
const sdk = await init();
const isValid = await sdk.form.isValid({
title: 'hello world',
});

console.log(isValid); // false
`

$3

For syncing your model with Dynamic Content on content changes outside the extension e.g delivery key change

`js
const sdk = await init();

sdk.form.onModelChange((errors, model) => {
setErrors(errors);
setModel(model);
});
`

returns a unsubscribe function to unsubscribe call back

`js
const unsubscribe = sdk.form.onModelChange((errors, model) => {
setErrors(errors);
setModel(model);
});

unsubscribe();
`

Client (Supported on Content Field, Dashboard & Content Editor extensions)

Use client with dc-management-sdk-js

`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 & Content Editor extensions)

Return users logged in to the Content Management application

`js
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',
}
