-> Package description
+> Tiny, fast, dependency-free 64-bit [FNV-1a](http://www.isthe.com/chongo/tech/comp/fnv/) string hash for Node and the browser.
 
-## Usage
+The core computes a true 64-bit hash in two 32-bit lanes with plain JS numbers. It's ~320B gzipped (minified) and hashes a short key in ~36ns.
+
+## Why
+
+I created this for [Nuxt](https://github.com/nuxt/nuxt) due to the following issues with other FNV packages. These are all good packages and you should consider them if you don't have the same constraints I did:
 
-Install package:
+| Package | Width | Gzip | Notes |
+| --- | --- | --- | --- |
+| `fnv1a`, `object-code` | 32-bit | tiny | collides at ~50k distinct keys |
+| `@sindresorhus/fnv1a` | 64-bit | ~1KB | BigInt, ~20x slower |
+| `fnv-lite` | 128-bit | ~1.4KB | byte arrays, ~40x slower |
+| `fnv-plus` | multi | ~9KB | _excellent_ package, but contains lots of utilities |
+| `fnv-hash` | 64-bit | native | can't run in the browser |
+
+## Usage
 
 ```sh
-# npm
-npm install package-name
+npm install fnv1a-64
+```
+
+```js
+import { fnv1a64, fnv1a64Base36, fnv1a64BigInt, fnv1a64Hex } from 'fnv1a-64'
 
-# pnpm
-pnpm install package-name
+fnv1a64Hex('hello world') // => '779a65e7023cd2e7'  (16-char zero-padded hex)
+fnv1a64Base36('hello world') // => '1th7cxzlyc0dj'  (shortest, good for cache keys)
+fnv1a64BigInt('hello world') // => 8618312879776256743n
+fnv1a64('hello world') // => { high: 2006607335, low: 37540583 }  (fast core, no BigInt)
 ```
 
+- **`fnv1a64Hex`** and **`fnv1a64Base36`** are what you usually want as a map or cache key.
+- **`fnv1a64`** returns the raw 32-bit lanes and is the fastest path if you never need a string.
+- **`fnv1a64BigInt`** composes the lanes into a `bigint` when you want a single comparable number.
+
+All outputs are deterministic: the same input always produces the same result. Hex is always exactly 16 characters; base36 length varies with the value but is stable per value.
+
+## Non-ASCII: UTF-16 code units, not UTF-8 bytes
+
+The hash iterates `str.charCodeAt(i)`, so it hashes UTF-16 code units rather than UTF-8 bytes. For **ASCII input this is bit-for-bit identical to a canonical FNV-1a-64**. For non-ASCII (accents, CJK, emoji) the output is stable and collision-resistant but will **not** match an FNV-1a-64 computed over the UTF-8 encoding of the same string.
+
+If you need to interoperate with a hash produced elsewhere over UTF-8 bytes, encode first:
+
 ```js
-import {} from 'package-name'
+const bytes = new TextEncoder().encode(str)
+// then hash the bytes with a UTF-8-aware FNV-1a-64 implementation
 ```
 
+> [!IMPORTANT]
+
+> FNV-1a is a fast, **non-cryptographic** hash. It's useful for hash tables, cache keys, checksums, and bucketing, but do not use it for anything security-sensitive: it is not collision-resistant against an adversary and offers no preimage resistance.
+
+## Benchmark
+
+Run `pnpm bench` (uses [mitata](https://github.com/evanwashere/mitata)). Indicative numbers on Node 22 (Apple silicon), lower is better:
+
+| | width | short key | 1 KB string |
+| --- | --- | --- | --- |
+| `fnv1a64` (lanes) | 64 | **~42 ns** | ~2.7 µs |
+| `fnv1a64Base36` | 64 | ~98 ns | ~2.8 µs |
+| `fnv1a64Hex` | 64 | ~339 ns | ~3.0 µs |
+| `fnv-plus` `fast1a64` | 64 | ~63 ns | **~1.7 µs** |
+| `murmurhash` v3 | 32 | ~257 ns | ~1.7 µs |
+| `@sindresorhus/fnv1a` | 64 | ~714 ns | ~29 µs |
+| `fnv-lite` `hex` | 128 | ~5.6 µs | ~297 µs |
+| `xxhashjs` `h64` | 64 | ~34 µs | ~59 µs |
+
+The `fnv1a64` core wins short keys outright. `fnv-plus` is competitive (and faster on long strings) but ships ~9 KB gzipped for a whole multi-width toolkit rather than one function. `murmurhash` is faster than 64-bit alternatives but is 32-bit, so it collides. `fnv-lite` and `xxhashjs` pay a large constant cost for their byte-array / `cuint` internals.
