How do you guys reset a react component state value to it’s initial value? I want a nice dry way of doing it! :slightly_smiling_face:

Use redux, and set `state=undefined` to reset to initialState :smile:

```
const initialState = {};
class Foo extends React.Component {
  state = initialState;
  reset() {
    this.setState(initialState);
  }
  ...
}
```

This only works if all the keys you use in state are defined in `initialState`; if you register more keys later then those won’t be removed.

There used to be a `replaceState` API but I think it’s removed or deprecated.

Maybe you can use `this.setState(() =&gt; {})`
But maybe it might be a anti-pattern to add new keys to state inside your component(s).

nvm setState doesn’t overwrite missing keys…

a hoc that unmounts and mounts again maybe?

You could do `this.setState(Object.assign(mapKeys(this.state, () =&gt; undefined), this.initialState))`
