## README

# is64bit

> Check whether operating system CPU architecture is 64-bit or 32-bit

This package also works in the browser. It can be useful to serve the correct binary for download.

On Node.js, [`process.arch` / `os.arch()`](https://nodejs.org/api/process.html#processarch) is generally not useful as it returns the CPU architecture for which the Node.js binary was compiled, not the actual system architecture.

## Install

```sh
npm install is64bit
```

## Usage

```js
import {is64bit} from 'is64bit';

// On ARM64 macOS
console.log(await is64bit());
//=> true
```

## API

### is64bit()

Returns a `Promise<boolean>` for whether the operating system CPU architecture is 64-bit.

### is64bitSync()

Returns a `boolean` for whether the operating system CPU architecture is 64-bit.

**Note**: Prefer the async version for browser or cross-platform usage as it has a more reliable check.
