Twilio has invested in providing a CLI and Serverless module that allow for streamlined debugging and deploying of plugins and functions for its Flex platform. This blog post will show developers how to take full advantage of these capabilities, starting with setting up a local environment using VS Code and dependencies such as Ngrok and the Twilio CLI. The process involves installing the necessary packages, initializing the Flex plugin and Twilio Functions, and configuring the debugging setup in VS Code. Once set up, developers can deploy their plugins and functions to Twilio's platform using the Twilio CLI, and test their functionality in a real-world environment. The post also covers common tips and tricks for debugging and deploying Flex plugins and functions, as well as additional resources for further learning.
