Mobx-state-tree afterCreate() not synchronous in react native

I am trying to load my application initialState by performing a load()
function in the afterCreate()
of my UserModel
. What I am trying to do is to load an Authenticated
page instead of a Login
page if I detect that the accessToken
is not empty in the UserStore
.
However the page renders before the afterCreate()
load function is ran. Which ends up always leading me to the login page.
I followed mainly this video tutorial by egghead.io but I am not sure why it's not working in my case.
I'm really stuck and any suggestions is appreciated!
The way I am passing my store is passing in the store using Provider
in my App.js
.
UserModel.js
const User = types
.model("User", {
accessToken: types.string
})
.actions(self => ({
afterCreate() {
self.load();
},
load: flow(function*() {
const localData = yield LocalDB.get("user");
applySnapshot(self, localData);
})
}));
The object LocalDB
is just a wrapper around AsyncStorage
to help parse the data into json format.
LocalDB.js
const LocalDB = {
get: async function(key) {
try {
let value = await AsyncStorage.getItem(key);
try {
return JSON.parse(value);
} catch (err) {
return value;
}
} catch (err) {
console.error(err);
return false;
}
App.js
let store = UserStore.create({...})
export default class App extends Component {
render() {
return (
<Provider store={store}>
<Router />
</Provider>
);
}
}

Seems like I found the issue. I was initializing my store with some default variables at the start like this:
let store = UserStore.create({accessToken: ""})
Once I updated it to null
it works fine.
let store = UserStore.create({accessToken: null})
