Funcatron is a functional framework for composing Node applications.

const funcatron = require('funcatron')
const http = funcatron([{
    path: "/hello",
    method: "get",
    handler: ({req, res}) => res.end("Hello world! Yours sincerely, Funcatron")
}]).listen(8000)

There are lots of great frameworks for writing Node applications, but none of them focus on functional programming.

(If that statement is inaccurate, please open an issue and I'll mention them here and how they differ.)

Both Funcatron and Express are middleware style, minimal frameworks, although the API is totally different and Funcatron's focus on functional programming is certainly different.

Sails is a full-featured and relatively-opinionated framework. It has opinions about framework architecture (MVC) and comes with things like an ORM. With Funcatron, it has no opinions about those things and you can plug in your own ORM if necessary.

• Functional programming (obviously)
• Testable - applications should be easy to test
• Elegant - composing asynchronous pipelines to handle requests should easy and elegant
