react-use-slice

A react hook to use reducers with an API like createSlice from Redux toolkit, in a typesafe way, with performance in mind.

Install

npm install react-use-slice

Example

JavaScript

import { createContext } from 'react';
import useSlice from 'react-use-slice';

const initialState = {
  score: 0
};

const scoreSlice = {
  name: 'score', // "name" is optional. It is used in dev tools
  initialState,
  reducers: {
    increment(state, payload) {
      const score = state.score + 1;
      return { ...state, score };
    },
    decrement(state, payload) {
      const score = state.score - 1;
      return { ...state, score };
    }
  }
};

export const ScoreContext = createContext(null);

export const ScoreProvider = ({ children }) => {
  // Actions will be automaticaly dispatched
  const [state, actions] = useSlice(scoreSlice);

  return (
    <ScoreContext.Provider value={{ ...state, ...actions }}>
      {children}
    </ScoreContext.Provider>
  );
};

TypeScript

import { createContext } from 'react';
import useSlice, { createSlice, CombineStateAndActions } from 'react-use-slice';

const initialState = {
  score: 0
};

const scoreSlice = createSlice({
  name: 'score', // "name" is optional. It is used in dev tools
  initialState,
  reducers: {
    increment(state, payload: number) {
      const score = state.score + 1;
      return { ...state, score };
    },
    decrement(state, payload: number) {
      const score = state.score - 1;
      return { ...state, score };
    }
  }
});

export const ScoreContext =
  createContext<CombineStateAndActions<typeof scoreSlice> | null>(null);

export const ScoreProvider = ({ children }) => {
  // Actions will be automaticaly dispatched
  const [state, actions] = useSlice(scoreSlice);

  return (
    <ScoreContext.Provider value={{ ...state, ...actions }}>
      {children}
    </ScoreContext.Provider>
  );
};
