State Tracking

We will walk through a complete example which shows how to setup Trrack for pure state-based provenance tracking.

We start by creating our initial state:

const state = {
  counter: 0,
};

Then we initialize the registry and register an state-update action which increments the counter with a value:

const registry = Registry.create();
 
const incrementAction = registry.register('increment', (state, val) => {
  state.counter += val;
});

We can use the state and registry to initialize Trrack as follows:

const trrack = initializeTrrack({
  initialState: state,
  registry,
});

We can trigger updates to state by using incrementAction as follows:

trrack.apply('Increment by 1', incrementAction(1));

Here is a sandbox which shows state based provenance trracking.
