    Extend the React Quick Deploy Video App with DataTracks header - Extend the React Quick Deploy Video App with DataTracks

    In March, Twilio released quick deploy video apps for three different platforms - React.js, iOS, and Android. These apps are fully functioning video collaboration apps that can be deployed to the cloud in minutes. They serve as a canonical reference for developers building out their communication solutions by showcasing the features and capabilities of Programmable Video.

    When you build a video app, you can get pretty far with just audio and video. But what if you want to go above and beyond audio and video to build more engaging video experiences by adding hand-raising, annotations, whiteboarding, and more?

    The answer is DataTracks. With Twilio Video, you can use DataTracks to send real-time ephemeral data such as text, JSON, or binary data to other participants in a video call. We say the data is ‘ephemeral’ because it isn’t persisted anywhere. If you aren’t in a room when …

    Writing Metal Lyrics with OpenAI's GPT-3 Engine, Twilio Functions, and JavaScript header - Writing Metal Lyrics with OpenAI's GPT-3 Engine, Twilio Functions, and JavaScript

    As a musician/songwriter, one thing I find myself struggling with all too often is writing unique,  compelling song lyrics. Metal lyrics in particular are especially difficult for me. Writer's block is usually the issue, but even worse is when I come up with a great line to start but nothing to follow it.

    Thanks to OpenAI and their GPT-3 API, this is no longer an issue. Now I can just write a few lines myself and let a trained model write the rest. Is it cheating? Probably. But is it fun? Definitely.

    This post will demonstrate how to use Twilio Functions to assist in writing song lyrics by using OpenAI's GPT-3 engine and their Completion API. Here are a few examples of interesting lyrics I was able to generate using this tool:
