05h

05h

Stable 32-bit string hash (FNV-1a) with a bucketing helper. Zero dependencies.

Same input always yields the same unsigned 32-bit integer on every platform and every Node version — suitable for stable sharding, cache keys and reproducible (seeded) ordering.

const hash = require('05h');

hash('hello');          // 1335831723
hash('hello');          // 1335831723   (always the same)
hash('hello', 100);     // 23           (in [0, 100))
hash.bucket('id', 8);   // 0..7         (shard index)

API

hash(value, modulo?)

Returns an unsigned 32-bit number.

hash.bucket(value, buckets)

Convenience wrapper returning a stable index in [0, buckets).

Notes

Not a cryptographic hash — do not use it for security purposes.
