As noted by Kalle [on the discord](https://discord.com/channels/448698263508615178/506757962388209664/735059350149922936) with the new release of ImmerJS, you can now use it correctly with Aurelia store. In a nutshell:

1. Disable auto-freeze with `setAutoFreeze(false);`
2. Write your actions like this:

```auto
export const selectBackend = produce((state: State, selectedBackend: SelectableBackend) => {
    state.selectedBackend = selectedBackend;
});

```

1. Only modify the state directly: immer will track its modification to create a new object but won’t modify the existing one. If you modify any other parameter directly, it will be mutated.

If you need more details, I wrote [a detailed blog post](https://www.jujens.eu/posts/en/2020/Aug/09/aurelia-store-immerjs/).
