Blocks rendering

Use createMakeCodeRenderBlocks to create a MakeCode block renderer. Initialise the renderer before calling renderBlocks with a RenderBlocksRequest, which includes a MakeCode project (see examples). The function will return a RenderBlocksResponse.

import { createMakeCodeRenderBlocks } from "@microbit/makecode-embed/vanilla";

const renderer = createMakeCodeRenderBlocks({});
renderer.initialize();
const result = await renderer.renderBlocks({ code: makeCodeProject });

document.querySelector<HTMLDivElement>("#app")!.innerHTML = `
  <div>
    ${result.svg}
  </div>
`;
Copy

Embed MakeCode editor

Use MakeCodeFrameDriver class to create a driverRef for an iframe element. The iframe element src URL can be generated using createMakeCodeURL.

import {
  MakeCodeFrameDriver,
  createMakeCodeURL,
} from "@microbit/makecode-embed/vanilla";

// Set up an iframe element.
const iframe = document.createElement("iframe");
iframe.allow = "usb; autoplay; camera; microphone;";
iframe.src = createMakeCodeURL(
  "https://makecode.microbit.org",
  undefined, // Version.
  undefined, // Language.
  1, // Controller.
  undefined // Query params.
);
iframe.width = "100%";
iframe.height = "100%";

document.querySelector<HTMLDivElement>("#app")!.appendChild(iframe);

// Create and initialise an instance of MakeCodeFrameDriver.
const driverRef = new MakeCodeFrameDriver(
  {
    controllerId: "YOUR APP NAME HERE",
    initialProjects: async () => [makeCodeProject],
    onEditorContentLoaded: (e) => console.log("MakeCode is now ready"),
    onWorkspaceSave: (e) => {
      console.log(e.project!.header!.id, e.project);
    },
  },
  () => iframe
);
driverRef.initialize();
Copy
