system-architecture

Get the operating system CPU architecture

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.

For browser usage, you probably want is64bit instead.

Install

1npm install system-architecture

Usage

1import {systemArchitecture} from 'system-architecture';
2
3// On ARM64 macOS
4console.log(await systemArchitecture());
5//=> 'arm64'

API

systemArchitecture()

Returns a promise for a CPU architecture name. See process.arch for possible values.

systemArchitectureSync()

Returns a CPU architecture name. See process.arch for possible values.

Note

This should really be in Node.js core, but they are not pragmatic.
