async function main() {
  const fastboard = await createFastboard({
    // [1]
    sdkConfig: {
      appIdentifier: "whiteboard-appid",
      region: "us-sv", // "cn-hz" | "us-sv" | "sg" | "in-mum" | "gb-lon"
    },
    // [2]
    joinRoom: {
      uid: "unique_id_for_each_client",
      uuid: "room-uuid",
      roomToken: "NETLESSROOM_...",

    netlessApps: [],
  });

  const container = createContainer();

  const ui = createUI(fastboard, container);

  // .....

  // destroy Fastboard UI
  ui.destroy();

  // .....

  // destroy Fastboard (disconnect from the whiteboard room)
  fastboard.destroy();
}

function createContainer() {
  const container = document.createElement("div");
  // Must give it a visible size
  Object.assign(container.style, {
    height: "400px",
    border: "1px solid",
    background: "#f1f2f3",
  });
  document.body.appendChild(container);
  return container;
}

main().catch(console.error);

React

Install @netless/fastboard-react, use the <Fastboard /> component.

npm add @netless/fastboard-react @netless/window-manager white-web-sdk react react-dom
import { useFastboard, Fastboard } from "@netless/fastboard-react";
import React from "react";
import { createRoot } from "react-dom/client";

function App() {
  const fastboard = useFastboard(() => ({
    sdkConfig: {
      appIdentifier: "whiteboard-appid",
      region: "us-sv", // "cn-hz" | "us-sv" | "sg" | "in-mum" | "gb-lon"
    },
    joinRoom: {
      uid: "unique_id_for_each_client",
      uuid: "room-uuid",
      roomToken: "NETLESSROOM_...",
    },
  }));

  return <Fastboard app={fastboard} />;
}

// The root element must have a visible size
createRoot(document.getElementById("app")).render(<App />);

Whiteboard Functions

Insert Picture

await fastboard.insertImage(fileUrl);

The fileUrl is the url to load the image file, like "src" in <img src>. Fastboard itself does not contain any logic about upload/save a file.

Redo & Undo

fastboard.undo();
fastboard.redo();

Move Camera

fastboard.moveCamera({ centerX: 0, centerY: 0, scale: 1 });
fastboard.moveCameraToContain({ originX: -300, originY: -200, width: 600, height: 400 });

Set Tool

fastboard.setAppliance("pencil");
fastboard.setAppliance("shape", "triangle");
fastboard.setStrokeWidth(2);
fastboard.setStrokeColor([r, g, b]);

Netless Apps

Register & Insert Apps

Except for built-in apps in Fastboard, you can also insert your own apps. To do that, You have to register app at each client before entering room (createFastboard):

import { register } from "@netless/fastboard";
import MyApp from "my-app";

register({ kind: MyApp.kind, src: MyApp });

Or you can set netlessApps in createFastboard config:

createFastboard({
  ..., // other config
  netlessApps: [MyApp],
});

Then add app into the room via:

fastboard.manager.addApp({ kind: MyApp.kind });

Read more about Netless Apps.

Insert PDF, PPT and PPTX

// insert PDF/PPT/PPTX to the main whiteboard
const appId = await fastboard.insertDocs("filename.pptx", conversionResponse);

The conversionResponse is the result of this api.

Note: If you're using the new projector api, please use the manual way:

const appId = await fastboard.insertDocs({
  fileType: "pptx",
  scenePath: `/pptx/${response.uuid}`,
  taskId: response.uuid,
  title: "filename.pptx",
});

Insert Video & Audio

const appId = await fastboard.insertMedia("filename.mp3", fileUrl);

The fileUrl is the url to load the media file, like "src" in <video src>. Fastboard itself does not contain any logic about upload/save a file.

Insert @netless/app-monaco

const appId = await fastboard.manager.addApp({
  kind: "Monaco",
  options: { title: "Code Editor" },
});

Insert @netless/app-countdown

const appId = await fastboard.manager.addApp({
  kind: "Countdown",
  options: { title: "Countdown" },
});

Insert @netless/app-geogebra

const appId = await fastboard.manager.addApp({
  kind: "GeoGebra",
  options: { title: "GeoGebra" },
});

Insert @netless/app-plyr

const appId = await fastboard.manager.addApp({
  kind: "Plyr",
  options: { title: "YouTube" },
  attributes: {
    src: "https://www.youtube.com/embed/bTqVqk7FSmY",
    provider: "youtube",
  },
});

Insert @netless/app-embedded-page

const appId = await fastboard.manager.addApp({
  kind: "EmbeddedPage",
  options: { title: "Google Docs" },
  attributes: {
    src: "https://docs.google.com/document/d/1bd4SRb5BmTUjPGrFxU2V7KI2g_mQ-HQUBxKTxsEn5e4/edit?usp=sharing",
  },
});

Note: EmbeddedPage uses <iframe> to display external web resources, you'd better not embedding 2 more nested iframes (i.e. webpage>iframe1>iframe2) in the same page.

More apps goto netless-app.
