use-slice v0.1.3

useSlice

A lightweight local state management hook. Heavily inspired by redux-starter-kit. See createSlice.

Usage

useSlice(initialState, reducers)

Parameters

• initialState {object} - The initial state of your slice.

• reducers {object} - An object of functions that perform an action to update state.

Example

import { useSlice } from 'use-slice';

function EditInfo() {
    // Default state of a our slice (person)
    const initialState = { name: '', birthdate: '', age: '' }

    // Actions that can be performed on our slice of state
    const reducers = {
        setName(state, name) {
            state.name = name
            return state
        },
        setBirthdate(state, birthdate) {
            state.birthdate = birthdate;
            state.age = getYearsSince(birthdate);
            return state
        },
    };

    // The current state of our slice, the dispatcher, and its actions
    const [state, dispatch, actions] = useSlice(initialState, reducers)
    const { name, birthdate, age } = state;
    const { setName, setBirthdate } = actions;

    // Handlers that can be used to update our slice
    const updateName = name => dispatch(setName(name))
    const updateBirthdate = birthdate => dispatch(setBirthdate(birthdate))

    return ( ... );
