distillate

distillate is a zero-dependency library of approximate membership query filters for JavaScript: Bloom, Blocked Bloom, and Binary Fuse. Each structure answers “have I seen this key?” in a fraction of the space an exact set needs, at a tunable false positive rate.

New here? Start with what an AMQ filter is, watch one work in the playground, then install it. To pick between the three, see choosing a structure.
