State

Each Unifire instance accepts state which must be an object.

const state = { count: 0 };

const counter = Unifire({ state });

Now that we have our counter, we need to be able to interact with it.

To read state from your store, just access it.

const currentCount = counter.state.count;

To write to your store, just mutate state;

counter.state.count = 1;

To subscribe to changes to counter.state.count, call subscribe and access count.

counter.subscribe(({ count }) => console.log('count', count));

This subscriber will only be called when counter.state.count changes. (For more on subscribers, see the Subscribers section.)

Working with non-primitives

When making assignments to non-primitives such as objects or arrays, be certain to change the value's memory address or the mutation will not trigger subscribers.

// Setup our store with an object
const state = {
  obj: { a: 'a' }
};
const counter = Unifire({ state });

// Will trigger subscribers
store.state.obj = { a: 'b' };

// Will NOT trigger subscribers
store.state.obj.a = 'b';
