ANSWER

Answered 2021-Jun-02 at 14:53

I don't think it's so easy to adapt the existing lru_cache, and I don't think that linked method is very clear.

Instead I implemented a timed lru cache from scratch. See the docstring at the top for usage.

It stores a key based on the args and kwargs of the inputs, and manages two structures:

A mapping of key => (expiry, result)
A list of recently used, where the first item is the least recently used

Every time you try to get an item, the key is looked up in the "recently used" list. If it isn't there, it gets added to the list and the mapping. If it is there, we check if the expiry is in the past. If it is, we recalculate the result, and update. Otherwise we can just return whatever is in the mapping.

create-react-native-app@1.0.0 is not supported anymore, that version was released 4 years ago and the latest version is 3.5.3. you can leave out the version to get the latest - yarn global add create-react-native-app or use yarn create react-native-app or npx create-react-native-app.

also, if you're looking to create a managed expo project, i'd suggest installing expo-cli instead - npm i -g expo-cli and then run expo init. full installation docs here.
