Twilio Functions now supports npm, a package manager for JavaScript that makes it easy to share and reuse code, allowing developers to leverage the ecosystem of packages and modules provided by the Node.js community with no need to upload or manage packages manually. With this addition, Twilio Functions Packages automatically retrieves, installs, and deploys third-party packages, taking care of logistics behind the scenes, so developers can focus on using them. Developers can start using npm modules inside their functions by including them with the `require()` method, ensuring consistent and up-to-date function environments with every change to the npm list deployed instantly.
