State Machines for WhatsApp Messaging Bots with Node.js

This summary provides an overview of implementing a state machine in a messaging bot using Vonage's Messages API and Express.js. The bot receives incoming messages, checks the state database to determine the current state, and updates the state accordingly. The state machine is designed to guide the user through a series of steps, such as username registration, email address collection, and payment confirmation. The server uses an Express.js server with Vonage's Messages API to handle incoming messages and update the state database. The code provides examples of how to implement the state machine, including creating a database, defining states, and updating the state. The summary highlights the importance of using a state machine in messaging bots and provides resources for further learning about the Vonage Messages API.
