To create an application that allows room participants to join, communicate, and share transcripts, and also enables live transcription of their microphones, the following key points can be noted: A video call web app project was cloned, and the Twilio Programmable Video JavaScript SDK was used to create a video room. An enhanced version of the MediaRecorder API was used to record the room participants' microphones in 6-second intervals, along with the Transformers.js package alongside a Whisper model to transcribe the audio recordings. The DataTrack API was utilized to share the transcripts among the room participants. A server application was created using Express.js that served static assets and handled video call room creation and access token generation. Live transcription functionality was added by utilizing the MediaRecorder API, sending recorded audio files to the server for transcription, and then displaying the transcript below the webcam feed.

A modern web application's sheer volume of data generated per second has made it inefficient for the client to simply poll the server, instead, the server should be able to send updates to the client at will. The Mercure protocol is an open protocol designed from the ground up to publish updates from server to clients, and it is a modern and efficient alternative to timer-based polling and to WebSocket. To set up a Mercure Hub for a Symfony application, you can either use Docker integration or by using the standalone binary, with two ways to set up a hub. In addition to setting up a hub, you will also learn how to dispatch and subscribe to hub updates. The prerequisites for this tutorial are a basic understanding of PHP and Symfony, PHP 8.0 or above, Composer globally installed, the Symfony CLI, and Docker desktop. To get started, create a new project and change into the new project directory, then add the project dependencies using the composer commands. While setting up the Mercure Hub, you will be able to use either Docker integration or by configuring the Mercure Hub as a static binary. Once set up, you can create a controller to test the newly set up hub, subscribe to updates from the Twig template, and run the application. The final step is to start your Symfony application and open two new tabs in your browser to test the setup with real-time push capabilities.
