Building a realtime SMS voting app... In the web.

This tutorial guides you through building a simple web app that receives and displays SMS votes in real time using Ably's Pub/Sub messaging service, Vonage Communications APIs, and Next.js framework. The app allows users to vote by sending an SMS message to a specific number, with the results displayed on a bar chart. The tutorial covers setting up accounts for Ably, Vercel, and Vonage, creating a serverless function to authenticate with Ably, building React components for the question and results display, receiving SMS messages using Vonage, and hosting the app on Vercel.
