Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Jellyfish React client

React client library for Jellyfish. It is a wrapper around the Jellyfish TS client.

Documentation

Documentation is available here or you can generate it locally:

npm run docs

Installation

You can install the library using npm:

npm install @jellyfish-dev/react-client-sdk

It was tested with nodejs version mentioned in .tool-versions file.

Usage

For pure TypeScript usage, see Jellyfish TS client.

Prerequisites:

  • Running Jellyfish server.
  • Created room and token of peer in that room. You can use dashboard to create room and peer token.

This snippet is based on minimal-react example.

// main.tsx
import React from "react";
import ReactDOM from "react-dom/client";
import { App, JellyfishContextProvider } from "./components/App";

ReactDOM.createRoot(document.getElementById("root") as HTMLElement).render(
  <React.StrictMode>
    <JellyfishContextProvider>
      <App />
    </JellyfishContextProvider>
  </React.StrictMode>,
);

// components/App.tsx
import VideoPlayer from "./VideoPlayer";
import { SCREEN_SHARING_MEDIA_CONSTRAINTS } from "@jellyfish-dev/react-client-sdk";
import { create } from "@jellyfish-dev/react-client-sdk";
import { useState } from "react";

// Example metadata types for peer and track
// You can define your own metadata types just make sure they are serializable
export type PeerMetadata = {
  name: string;
};

export type TrackMetadata = {
  type: "camera" | "screen";
};

// Create a Membrane client instance
// remember to use JellyfishContextProvider
export const { useApi, useTracks, useStatus, useConnect, useDisconnect, JellyfishContextProvider } = create<
  PeerMetadata,
  TrackMetadata
>();

export const App = () => {
  const [token, setToken] = useState("");

  const connect = useConnect();
  const disconnect = useDisconnect();
  const api = useApi();
  const status = useStatus();
  const tracks = useTracks();

  return (
    <div>
      <input value={token} onChange={(e) => setToken(() => e?.target?.value)} placeholder="token" />
      <div>
        <button
          disabled={token === "" || status === "joined"}
          onClick={() => {
            if (!token || token === "") throw Error("Token is empty");
            connect({
              peerMetadata: { name: "John Doe" }, // example metadata
              token: token,
            });
          }}
        >
          Connect
        </button>
        <button
          disabled={status !== "joined"}
          onClick={() => {
            disconnect();
          }}
        >
          Disconnect
        </button>
        <button
          disabled={status !== "joined"}
          onClick={() => {
            // Get screen sharing MediaStream
            navigator.mediaDevices.getDisplayMedia(SCREEN_SHARING_MEDIA_CONSTRAINTS).then((screenStream) => {
              // Add local MediaStream to webrtc
              screenStream.getTracks().forEach((track) => api.addTrack(track, screenStream, { type: "screen" }));
            });
          }}
        >
          Start screen share
        </button>
        <span>Status: {status}</span>
      </div>
      {/* Render the remote tracks from other peers*/}
      {Object.values(tracks).map(({ stream, trackId }) => (
        <VideoPlayer key={trackId} stream={stream} /> // Simple component to render a video element
      ))}
    </div>
  );
};
