Save your application state in query string between page views.
String, Number and Boolean and Array values will be saved as is, while object values will be encoded as JSON.
Idea is simple. When state in initiated, we read it from the query string. Whenever it changes, we write it to the query string. This keeps start between page views and allows sharing urls of a given state.
import { saveStateToURL, readStateFromURL } from "state-as-querystring";
class App extends React.Component {
// read state from url when initializing the store
constructor(props) {
super(props);
this.state = readStateFromURL();
}
//save state to url when state is changed
componentDidUpdate() {
saveStateToURL(this.state);
}
render() {
return (
<textarea
value={this.state.text}
/>
);
}
}
import { saveStateToURL, readStateFromURL } from "state-as-querystring";
// read state from url when initializing the store
const store = createStore(reducer, readStateFromURL());
// save state to url when state changes
store.subscribe(() => saveStateToURL(store.getState()));A bit more complex example - with arrays in the state + partial syncing of the state.
