  • Use kontent-delivery.browser.legacy.umd.min if you need to support legacy browsers (IE9, IE10, IE11)
  • Use kontent-delivery.browser.umd.min if you intend to use SDK only in browsers (strips code specific to Node.js = smaller bundle)
  • Use kontent-delivery.umd.min if you need to use it in Node.js

TypeScript & ES6

import { 
    ContentItem, 
    Elements,
    TypeResolver,
    DeliveryClient
    } from '@kentico/kontent-delivery';

/**
 * This is optional, but it is considered a best practice to define your models
 * so you can leverage intellisense and so that you can extend your models with 
 * additional properties / methods.
 */
export class Movie extends ContentItem {
  public title: Elements.TextElement;
}

const deliveryClient = new DeliveryClient({
    projectId: 'xxx',
    typeResolvers: [
        new TypeResolver('movie', () => new Movie()),
    ]
});

/** Getting items from Kentico Kontent as Promise */
deliveryClient.items<Movie>()
    .type('movie')
    .toPromise()
    .then(response => {
        const movieText = response.items[0].title.value;
    });

    .type('movie')
    .toObservable()
    .subscribe(response => {
        const movieText = response.items[0].title.value;
    });

/**
 * Get data without having custom models 
 */
deliveryClient.items<ContentItem>()
  .type('movie')
  .get()
  .subscribe(response => {
    // you can access properties same way as with strongly typed models, but note
    // that you don't get any intellisense and the underlying object 
    // instance is of 'ContentItem' type
    console.log(response.items[0].title.value);
});

JavaScript & CommonJS

const KontentDelivery = require('@kentico/kontent-delivery');

class Movie extends KontentDelivery.ContentItem {
    constructor() {
        super();
    }
}

const deliveryClient = new KontentDelivery.DeliveryClient({
    projectId: 'xxx',
    typeResolvers: [
        new KontentDelivery.TypeResolver('movie', () => new Movie()),
    ]
});

/** Getting items from Kentico Kontent as Promise */
deliveryClient.items()
    .type('movie')
    .toPromise()
    .then(response => {
        const movieText = response.items[0].title.value;
    });

/** Getting items from Kentico Kontent as Observable */
const subscription = deliveryClient.items()
    .type('movie')
    .toObservable()
    .subscribe(response => {
        const movieText = response.items[0].title.value;
    });

/*
Don't forget to unsubscribe from your Observables. You can use 'takeUntil' or 'unsubscribe' method for this purpose. Unsubsription is usually done when you no longer need to process the result of Observable. (Example: 'ngOnDestroy' event in Angular app)
*/
subscription.unsubscribe();

/**
 * Fetch all items of 'movie' type and given parameters from Kentico Kontent.
 * Important note: SDK will convert items to your type if you registered it. For example,
 * in this case the objects will be of 'Movie' type we defined above. 
 * If you don't use custom models, 'ContentItem' object instances will be returned.
 */
deliveryClient.items()
    .type('movie')
    .toObservable()
    .subscribe(response => console.log(response));

Testing

Note: You need to have Chrome installed in order to run tests via Karma.

  • npm run test:browser Runs tests in Chrome
  • npm run test:node Runs tests in node.js
  • npm run test:dev Runs developer tests (useful for testing functionality)
  • npm run test:travis Runs browser tests that are executed by travis

If you want to mock http responses, it is possible to use external implementation of configurable Http Service as a part of the delivery client configuration.
