Read and Update State

Reading and updating state in Neuron is very easy. You must call the methods below to perform each task.

Read state

Calling the get function will return the current value of the state. You must pass the correct key as a parameter and the store will use this to grab the correct state.

const currentState = Store.get("name");
console.log(currentState);
//Ash Ketchum

Update state

To update state you must call the set function. It takes two parameters, key and newValue.

Store.set("name", "Gary Oak");
//The new state would be 'Gary Oak'

Setting with the previous state

The set method can also take a predicate as its second parameter to grab the previous state value. Example below.

Store.set("name", (prev) => `${prev} is lame.`);
//The new state would be 'Gary Oak is lame'
