Text-to-Post Web App Tutorial - Twilio, Convex, Clerk, React, and TypeScript

Learn how to build a web application that processes incoming SMS messages with authentication, image storage, and a real-time database using Twilio, Convex, Clerk, React, and TypeScript. This 19-minute tutorial demonstrates how to create a complex workflow in under 200 lines of code. Set up a webhook to handle incoming text messages, store them for display in a React web app, manage user authentication and permissions, and implement file storage. Follow along as the instructor guides you through each step, from setting up credentials to testing the final application. Gain insights into the power of modern web development tools and learn why they're revolutionizing the way we build applications.
