Twilio Function Templates

Twilio Functions are a serverless environment to build and run Twilio applications so you can get to production faster. You provide the Node.js code to perform the task you need and Twilio runs it. You can read more about Twilio Functions and how to use them in the introductory blog post.

This repo

This repo is intended to be a collection of useful Twilio Functions that are tested and documented. The intention is that you can take any of these Functions and drop them into a project, confident they will work, whether you are a developer looking for a particular building block or a builder who just needs a particular Function. These templates are also available through twilio-run new inside the twilio-run CLI.

Usage

Each Function lives in its own directory within this repo. The easiest way to use the templates is through the Twilio CLI. Check out our docs for the different ways you can use these templates.

Github Pages

The Quick Deploy Functions in this repo contain an index.html asset that is displayed after a deployment succeeds. That index.html file is served by the Function itself, but several static assets shared by every index.html are served by Github Pages from the /docs/static directory of this repo. These files all follow semver versioning, and are located in a subdirectory of /docs/static named after their semver major version number. For example, a file of version 1.2.3 should have a comment header containing Version: 1.2.3 (if possible), and be located in the v1 subdirectory of /docs/static.
