# Installation

> USearch for JavaScript

```sh
npm install usearch
```

### Building From Source

The addon links against the C interface as a static archive, so `usearch.node` carries the engine inside it rather than beside it.
`cmake-js` compiles it, and `prebuild` stages it where `node-gyp-build` looks:

```sh
npm run prebuild
npm run build-js
npm test
```

The addon carries the dense storage types its CMake configure compiled: `npm run build-native` and the prebuilt addons pass `USEARCH_DENSE_DTYPES=11`, while a plain configure compiles `bf16`, `u1x8`, `i8` and `e4m3` alone, and the suite skips the kinds such a build refuses.
