> Tiny, fast, dependency-free 64-bit [FNV-1a](http://www.isthe.com/chongo/tech/comp/fnv/) string hash for Node and the browser.
9
+
10
+
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.
11
+
12
+
## Why
13
+
14
+
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:
15
+
16
+
| Package | Width | Gzip | Notes |
17
+
| --- | --- | --- | --- |
18
+
| `fnv1a`, `object-code` | 32-bit | tiny | collides at ~50k distinct keys |
19
+
| `@sindresorhus/fnv1a` | 64-bit | ~1KB | BigInt, ~20x slower |
20
+
| `fnv-lite` | 128-bit | ~1.4KB | byte arrays, ~40x slower |
21
+
| `fnv-plus` | multi | ~9KB | _excellent_ package, but contains lots of utilities |
22
+
| `fnv-hash` | 64-bit | native | can't run in the browser |

## Usage
11
25
12
-
Install package:
26
+
```sh
27
+
npm install fnv1a-64
28
+
```
13
29
14
-
```sh
15
-
# npm
16
-
npm install package-name
30
+
```js
31
+
import { fnv1a64, fnv1a64Base36, fnv1a64BigInt, fnv1a64Hex } from 'fnv1a-64'
17
32
18
-
# pnpm
19
-
pnpm install package-name
33
+
fnv1a64Hex('hello world') // => '779a65e7023cd2e7' (16-char zero-padded hex)
34
+
fnv1a64Base36('hello world') // => '1th7cxzlyc0dj' (shortest, good for cache keys)
35
+
fnv1a64BigInt('hello world') // => 8618312879776256743n
36
+
fnv1a64('hello world') // => { high: 2006607335, low: 37540583 } (fast core, no BigInt)
20
37
```
21
38
39
+
- **`fnv1a64Hex`** and **`fnv1a64Base36`** are what you usually want as a map or cache key.
40
+
- **`fnv1a64`** returns the raw 32-bit lanes and is the fastest path if you never need a string.
41
+
- **`fnv1a64BigInt`** composes the lanes into a `bigint` when you want a single comparable number.
42
+
43
+
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.
44
+
45
+
## Non-ASCII: UTF-16 code units, not UTF-8 bytes
46
+
47
+
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.
48
+
49
+
If you need to interoperate with a hash produced elsewhere over UTF-8 bytes, encode first:
50
+
22
51
```js
23
-
import {} from 'package-name'
52
+
const bytes = new TextEncoder().encode(str)
53
+
// then hash the bytes with a UTF-8-aware FNV-1a-64 implementation
24
54
```
25
55
56
+
> [!IMPORTANT]
57
+
58
+
> 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.
59
+
60
+
## Benchmark
61
+
62
+
Run `pnpm bench` (uses [mitata](https://github.com/evanwashere/mitata)). Indicative numbers on Node 22 (Apple silicon), lower is better:
63
+
64
+
| | width | short key | 1 KB string |
65
+
| --- | --- | --- | --- |
66
+
| `fnv1a64` (lanes) | 64 | **~42 ns** | ~2.7 µs |
67
+
| `fnv1a64Base36` | 64 | ~98 ns | ~2.8 µs |
68
+
| `fnv1a64Hex` | 64 | ~339 ns | ~3.0 µs |
69
+
| `fnv-plus` `fast1a64` | 64 | ~63 ns | **~1.7 µs** |
70
+
| `murmurhash` v3 | 32 | ~257 ns | ~1.7 µs |
71
+
| `@sindresorhus/fnv1a` | 64 | ~714 ns | ~29 µs |
72
+
| `fnv-lite` `hex` | 128 | ~5.6 µs | ~297 µs |
73
+
| `xxhashjs` `h64` | 64 | ~34 µs | ~59 µs |
74
+
75
+
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.
