Node.js parser for Rich text elements

This library is an optional addon for the javascript delivery SDK that can be used to resolve rich text elements in node.js environment.

This is an alternative to built-in browserRichTextResolver that comes native with the SDK and works in browsers.

Usage

Use nodeRichTextResolver when you need to resolve rich text elements in node.js environment

import { createDeliveryClient, linkedItemsHelper } from '@kentico/kontent-delivery';
import { nodeRichTextResolver } from '@kentico/kontent-delivery-node-js-parser';

export type Movie = IContentItem<{
    plot: Elements.RichTextElement;
}>;

export type Actor = IContentItem<{
    firstName: Elements.RichTextElement;
}>;

// get content item with rich text element
const response = (await createDeliveryClient({ projectId: 'projectId' }).item<Movie>('itemCodename').toPromise()).data;

// get rich text element
const richtElement = response.item.plot;

// resolve HTML
const resolvedRichText = nodeRichTextResolver.resolveRichText({
    element: richtElement,
    linkedItems: linkedItemsHelper.convertLinkedItemsToArray(response.linkedItems),
    imageResolver: (image) => {
        return {
            imageHtml: `<img class="xImage" src="${image?.url}">`,
            // alternatively you may return just url
            url: 'customUrl'
        };
    },
    urlResolver: (link) => {
        return {
            linkHtml: `<a class="xLink">${link?.link?.urlSlug}</a>`,
            // alternatively you may return just url
            url: 'customUrl'
        };
    },
    contentItemResolver: (contentItem) => {
        if (contentItem && contentItem.system.type === 'actor') {
            const actor = contentItem as Actor;
            return {
                contentItemHtml: `<div class="xClass">${actor.elements.firstName.value}</div>`
            };
        }

        return {
            contentItemHtml: ''
        };
    }
});

const resolvedHtml = resolvedRichText.html;

If you need to use async functions within resolvers, use the resolveRichTextAsync:

const resolvedRichText = await nodeRichTextResolver.resolveRichTextAsync({
    element: response.item.elements.plot,
    linkedItems: linkedItemsHelper.convertLinkedItemsToArray(response.linkedItems),
    imageResolver: async (image) => {
        // async function
        return {
            imageHtml: await customAsyncfunc()
        };
    },
    urlResolver: async (link) => {
        // async function
        return {
            imageHtml: await customAsyncfunc()
        };
    },
    contentItemResolver: async (contentItem) => {
        // async function
        return {
            contentItemHtml: await customAsyncfunc()
        };
    }
});
