By Phil Nash, creating an SMS bot on AWS Lambda with Claudia.js is easy and straightforward. Claudia.js abstracts away the differences between various bot platforms, making it a great tool for building chatbots. The author sets up a Twilio account and creates a new user profile in AWS IAM to deploy their bot. They then install Claudia.js as a development dependency and create a Node.js project to build their bot. The author defines a handler function that processes incoming messages and returns a response, which can be customized for different platforms. After writing the bot's code, they deploy it using the `create` script provided by Claudia.js. The bot is then configured to receive Twilio webhooks and is ready to send its first message. The author invites readers to try building their own bots with Claudia.js and AWS Lambda.
