Shift: Framework for Reusable Stateless Functions

Inspired by the trends in Serverless / FaaS / Cloud Functions.

Features:

• Provides a framework to build reusable stateless functions.
• A language agnostic (json) format to define inputs, outputs and configs that your functions need.
• A service.json format to list the Shift functions you'd like to expose.
• Uses JSON Schema to validate all input, output and configs.
• Invokers for your Shift functions, so you can easily call/host them locally or remotely.
• Supports functions implemented in PHP or any other language, including executing external commands.
• An HTTP end-point server to serve your functions.
• A Console tool to help build, test and debug your Shift functions.

Examples:

The example/ directory contains an example service with 2 functions, one implemented in PHP, and one generically executing an external CLI tool.

To test it out:

cd example/
../bin/shift invoke:local hello-php -i greeting=Howdy -c color=silver -u joe

This will call the hello-php function, passing one input (greeting), a config (color) and a context username.

Status

Shift is currently in an experimental phase, and some of the features are under construction.
