next-redux-hydrate v1.0.5

Next Redux Hydrate

A simple, lightweight library that dispatches a HYDRATE action when the app is on the client.

Motivation

I've always written my global states in Redux, I often use SocketIO for when I need a websocket connection to the server. Thus, when I switched to Next.JS there would be two connections, one for the SSR and one for the actual client. I needed a way to make sure the SocketIO connection only connects when the app is on the client. Having to write separate logic for every state and reducer is inefficient. Next-redux-wrapper provided a solution but covers too many usecases. I wanted something that would just be a hook that does its thing and then doesn't bother you.

Usage

Installation

NPM

npm install next-redux-hydrate

Yarn

yarn add next-redux-hydrate

Getting started

// _app.tsx (or .js)

// ...
import { useReduxHydrate } from "next-redux-hydrate";
// ...

// ...
const MyApp = ({ Component, pageProps }: AppProps) => {
  useReduxHydrate({ store });

  return (
  // ...

This dispatches HYDRATE when the app is on the client.

Using in reducers

// counterSlice.ts (or .js)

// ...
import { HYDRATE } from "next-redux-hydrate";

const initialState = {
  value: 1,
};

const counterSlice = createSlice({
  name: "counter",
  initialState,
  reducers: {
    // ...
  },
  // ...
  extraReducers: {
    // ...
    [HYDRATE]: (state) => {
      // Add 1 to the counter when the app is on the client
      state.value = state.value + 1;
    },
    // ...
  },
});
// ...

That's it!
