Deploying Twilio Functions with the Serverless extension for VSCode is made easier by an open-source VSCode integration that makes it straightforward to deploy Twilio functions from your IDE. The extension adds 6 commands to the VSCode command palette, including `Create Project`, `Start Local Server`, and `Deploy`. With these commands, users can create a new project, develop locally, create a new function, deploy to development, create an environment, and activate production. The process involves several steps, including installing prerequisites, logging in to the Twilio CLI, installing the extension, and using the various commands to scaffold out the project's files, start a local server, create a new function, deploy to development, create an environment, and activate production.
