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() is generally not useful as it returns the CPU architecture for which the Node.js binary was compiled, not the actual system architecture.

Install

npm install is64bit

Usage

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.
