Try on StackBlitz (You need to click "Open in New Tab")

Examples:

• React
• NextJS
• Rakkas

Quickstart:

import create from 'zustand';
import { querystring } from 'zustand-querystring';

interface Store {
  count: number;
  ticks: number;
  someNestedState: {
    nestedCount: number;
    hello: string;
  };
}

export const useStore = create<Store>()(
  querystring(
    (set, get) => ({
      count: 0,
      ticks: 0,
      someNestedState: {
        nestedCount: 0,
        hello: 'Hello',
      },
    }),
    {
      // select controls what part of the state is synced with the query string
      // pathname is the current route (e.g. /about or /)
      select(pathname) {
        return {
          count: true,
          // ticks: false, <- false by default

          someNestedState: {
            nestedCount: true,
            hello: '/about' === pathname,
          },

          // OR select the whole nested state
          // someNestedState: true
        };
      },
    },
  ),
);

querystring options:

• select - the select option controls what part of the state is synced with the query string
• key: string - the key option controls how the state is stored in the querystring (default: $)
• url - the url option is used to provide the request url on the server side render
