Range Queries Please 🤓

[mikeal]

Digging through the docs there doesn’t appear to be a way to do range queries even though it looks like the keys are ordered.

My ideal API for this would just be to add optional start, end, and ascending parameters to keys(), values() and entries(). So:

const onehour = 1000 * 60 * 60
const now = Date.now()
// query for everything from the last hour
for await (let [key, value] of db.entries(now, now + onehour, true)) {
  // do stuff
}

This might seem like a small feature but it’s something we rely on across the level ecosystem for creating more complex things on top of IDB today.

I would like to second this and also add that I would love to be able to specify if start & end should be inclusive or exclusive. In my package fanny-pack I've solved it by taking a range object that can have gt/gte & lt/lte. That way you can also only specify a lower, or only a upper bound if you want to.
