How to check the existence of a value in storage?

[Maryam Syed]

If I simply want to check if an object exists in the store, how do I do that? All I see are get and create methods that already factor in the existence of an object.

My specific use case is that if the object doesn't exist, I want to create it with certain values (default values) -- otherwise I want to leave it alone.

I can see this in the example codes:

store.get('key').then((value) => {
  if (value !== null) {
    // key exists
  } else {
    // key does not exist
  }
});

You can use it to do your thing.

@maryammouse, @aelallam's answer is probably your best bet. There is also a .keys function you could call to check the existence of a key. You could do something like this:

const keys = await store.keys();
if (keys.indexOf('key') === -1) {
  // key does not exist
} else {
  // key exists
}

This example assumes you are running this code inside an async function.
