feat/implement local storage persistence - WF-93

[FabienArcellier]

The application can save values ​​in local storage and retrieve them when the user reloads their page. This pattern allows you to introduce persistence beyond the current session.

If one value is not valid JSON, it'll throw and stop the execution of the initSession. It might be better to catch it and remove the entry if so.

It could be something like

Object.entries(localStorage)
  .filter(([key]) => key.startsWith("wf."))
  .reduce((acc, [key, value]) => {
    try {
      acc[key.replace('wf.', '')] = JSON.parse(value)
    } catch {
      localStorage.removeItem(key)
    }
  }, {});

We decided to remove this mechanism to use an interface closer to that of the browser. WF will only write strings to local storage. All keys will be loaded at startup and transferred to the backend.

I think there is no need to add error checking in this scenario. Am I right ?

You can add the type

Suggested change

	addMailSubscription("localStorageSetItem", (event) => {
	localStorage.setItem("wf." + event.key, JSON.stringify(event.value));
	});
	addMailSubscription("localStorageRemoveItem", (event) => {
	localStorage.removeItem("wf." + event.key);
	});
	addMailSubscription("localStorageSetItem", (event: LocalStorageSetItemEvent) => {
	localStorage.setItem("wf." + event.key, JSON.stringify(event.value));
	});
	addMailSubscription("localStorageRemoveItem", (event: LocalStorageRemoveItemEvent) => {
	localStorage.removeItem("wf." + event.key);
	});
