cogwheel v4.3.2

Cogwheel - simple JavaScript state machines

Simple finite state machines that can be used for state/process management.

Principles

Cogwheel is build around the following principles around state machines, and the library should be used as such:

• State transitions are synchronous & fire & forget by design;
• State transisions should not have side-effects, except for debugging purposes (e.g. console-log);
• The context should be serializable;
• All state & context mutations should be owned by the machine and its actions. This means as much (business) logic as possible should be included in the machine and its actions.

Actions

Migration v3.x.x > v4.x.x

• Remove all import { send, assign } from 'cogwheel';;
• Replace input parameters of all actions

const exampleAction({ state, event, assign, send }) {}
