A purely functional implementation of context-based operational transforms. Can be used for optimistic concurrency control in distributed systems. Works in the browser and in nodejs.

Installation:

npm install com.izaakschroeder.operational-transform

Responsible for sending messages between collaborators and implementing the network topology.

Built-in Transports

• Local: Star-topology for testing.
• Socket.IO: Star-topology for web-based OT.

Responsible for specifying the kinds of operations able to be performed as well as the necessary inclusion and inversion transformations.

Built-in Types

• Character: Character-wise insert/delete.
• Text: String-wise insert/delete.

Responsible for representing the state of a collaboration.

Built-in Contexts

• Set
• Vector

Determines how operations are transformed against others according to their concurrency/context relations.

Brings everything together.
