• Go
• Java
• Node.js (Coming Soon!)
• Python (Coming Soon!)
• Ruby (Coming Soon!)
• Docker (Coming Soon!)

Explore Fn

• Create Apps with Fn - Learn how to group your functions into an application/API and deploy them together.
• Create an Asynchronous Function - Learn how to write asynchronous functions for expensive, long running or batch processing.
• Create a Function with a Docker Container - This tutorial provides a simple example of how to define an Fn function using a custom built Docker container.

Test and Monitor Functions

• Write function tests - Fn provides an easy way to write tests for any language, that can ensure you don't break your function contract.
• Monitor Fn metrics with Grafana and Prometheus - Learn how to view Fn server metrics with Prometheus and Grafana.
• Troubleshoot functions - Resolve issues at both development and deployment time.

Orchestrate with Fn Flow

Fn Flow provides a way to orchestrate functions to build sophisticated applications, initially using Java, and soon with other programming languages.

• Flow 101
• Flow 102
• Fn Flow Saga - In this tutorial you will use Fn Flow to implement a Java travel booking system that leverages functions written in a variety of languages.
