redux - managing asynchronous storage using key-value pairs

Utilizing associative arrays with redux and storing them in async storage for later retrieval is my current challenge. When using redux, I am able to quickly access the values and efficiently map the content into cards in my react native app.

However, after storing the data in async storage, I encounter an issue where I have to JSON.stringify the content and then JSON.parse it upon loading. Unfortunately, I am unable to use the object in the same manner as before.

The structure of my data is as follows:

[ '1442-3338': { ID: '1442-3338', something: 'something', Participants: [] }, '1442-3339': { ID: '1442-3339', someting: 'something', secondArray: {} }, '1442-3340': { ID: '1442-3340', something: 'something', secondArray: {} }, '1442-3341': { ID: '1442-3341', something: 'something', secondArray: {} } ]

Initially, I can access the data using object['1442-3338']. However, after storing and retrieving the data with JSON.stringify and JSON.parse, I encounter difficulties reading the data as the keys are no longer recognized.

Answer №1

I came across the solution on a different forum.

JSON doesn't support named keys in arrays. As a result, when transforming the data with JSON.stringify and JSON.parse, the array lost its keys.

I had to switch to using a regular object instead, which resolved the issue.
