web integration framework

Knot.x is an open source framework integrating content from different sources like headless or traditional CMS, with systems like CRM, e-commerce or search engines.

The heart of Knot.x is the HTTP Server that uses Fragment Processing to connect many data sources into one customer experience (like HTML, JSON or PDF) in the configurable, reactive, scalable and fault-tolerant way.

A fragment is a piece of any kind of document that can be processed independently (e.g. an HTML snippet that represents the shopping cart or a JSON containing person's bookshelf).

Knot.x comes also with a distribution that enables quick start with the framework, is a project structure and supports deployment automation (see the Cookbook and Docker images).

We build Knot.x on top of Vert.x, known as one of the leading toolkits for performant, event-driven applications. It uses asynchronous programming principles which allows it to process a large number of requests using a single thread. Asynchronous programming is a style promoting the ability to write non-blocking code (no thread pools). The platform stays responsive under heavy and varying load and is designed to follow Reactive Manifesto principles.

Knot.x 2.0 development is in progress...
So far you may enjoy Knot.x 2.0.0-RC2.
