useHistoryState

useHistoryState is replacement for useState that stores the state within the history state.

The difference between useHistoryState and useState is that every changes in your state will be stored within the navigator history. And so, if you go back in your history, you will change the inner value of the state.

How to use

import React, { Fragment } from "react";
import useHistoryState from "use-history-state";

const Component = () => {
  // const [state, setState] = useHistoryState(initialValue, keyInHistoryState);
  const [name, setName] = useHistoryState("", "name");

  const names = ["John", "Susan", "Hugo", "Jade", "Mike", "Aurora"];

  return (
    <Fragment>
      <h1>{name}</h1>
      {names.map(n => (
        <button key={n} type="button" onClick={() => setName(n)} />
      ))}
    </Fragment>
  );
};

useHistoryState

function useHistoryState<State>(initialValue: State | () => State, key: string) {}

If there is already the specified key within the history's state, the initial value will be set to this value. Otherwise, it will you initialValue set as argument.

setState

function setState<State>(newState: State | State => void, replace?: boolean) {}

When you use the setState function, you can specify a second argument: replace.

• If replace is set to true, under the hood setState will use history.replaceState and so, if you want to go back to the previous page, you won't reach the replaced states.
• If replace is set to false, under the hood setState will use history.pushState, which means that every changes will be available in you history.

By default, replace is set to false
