  • We’ve removed large dependencies to reduce bundle size by 31%, making the SDK more lightweight and performant.
  • Lazy loading is now enabled by default to improve performance and reduce memory usage.

Why use the Twilio Node Helper?

The Node.js library offers new functionality and takes advantage of modern language features.

Here are a few reasons why we believe using an official Twilio Helper makes it easier, safer, and more efficient to build with Twilio.

  • Automatic serialization and deserialization: no more converting raw string or byte content into objects. All the error, return, and request types are included in the SDK.
  • Authentication made easy: our helper library provides the logic to authenticate with Twilio's API with ease.
  • All of Twilio's APIs at your fingertips: leverage all of Twilio's APIs through the helper, and easily extend your integration as your needs grow.
  • Request validation: our helper library helps ensure that incoming requests are coming from Twilio and not unknown actors.
  • Pagination support: automatically handle pagination across collections, such as messages and calls.

Try it out!

We can’t wait to see all the amazing things you’ll build with Twilio’s Node Helper Library 🚀.
