Usage

Transform card

Below is an example on how to transform a Hero card to Adaptive card.

import * as adaptiveCardTransformer from "adaptive-card-transformer";

// Define a HeroCard object
let heroCard: adaptiveCardTransformer.Hero.HeroCard = {
    title: "Hero title",
    subtitle: "Hero subtitle",
    text: "Hero text",
    images: [{
        "url": "https://hero.com/image.jpg"
    }],
    buttons: [{
        "type": "openUrl",
        "title": "View website",
        "value": "https://hero.com/website"
    }]
};

// Wrap it within a CardAttachment object
let heroCardAttachment: adaptiveCardTransformer.CardAttachment = {
    contentType: adaptiveCardTransformer.CardContentType.HeroCard,
    content: heroCard
};

// Transform the CardAttachment object
let transformedCardAttachment = adaptiveCardTransformer.transformCardAttachment(heroCardAttachment);

// Extract the transformed AdaptiveCard object
let adaptiveCard: adaptiveCardTransformer.Adaptive.AdaptiveCard = transformedCardAttachment.content;

Utilities

Additionally this package also provides few utilities like below.

import * as adaptiveCardTransformer from "adaptive-card-transformer";

// To recursively extract any type of elements from an Adaptive card json
let allImages = adaptiveCardTransformer.filterCardElements(adaptiveCardJson.body, "Image");
let first5TextBlocks = adaptiveCardTransformer.filterCardElements(adaptiveCardJson.body, "TextBlock", 5);
let allOpenUrlActions = adaptiveCardTransformer.filterCardElements(adaptiveCardJson.actions, "Action.OpenUrl");

// To derive the fallback text from an Adaptive card json
// This will return the adaptiveCard.fallbackText, if any, or
// the first TextBlock content, if any
let fallbackText = adaptiveCardTransformer.getCardFallbackText(adaptiveCardJson);

// To derive the fallback url from an Adaptive card json
// This will return the first Action.OpenUrl target giving preference to below order:
// 1. adaptiveCard.selectAction
// 2. adaptiveCard.actions
// 3. actionSet.actions within adaptiveCard.body
let fallbackUrl = adaptiveCardTransformer.getCardFallbackUrl(adaptiveCardJson);
