# system-architecture
|
|
|
|
> Get the operating system CPU architecture
|
|
|
|
[`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.
|
|
|
|
For browser usage, you probably want [`is64bit`](https://github.com/sindresorhus/is64bit) instead.
|
|
|
|
## Install
|
|
|
|
```sh
|
|
npm install system-architecture
|
|
```
|
|
|
|
## Usage
|
|
|
|
```js
|
|
import {systemArchitecture} from 'system-architecture';
|
|
|
|
// On ARM64 macOS
|
|
console.log(await systemArchitecture());
|
|
//=> 'arm64'
|
|
```
|
|
|
|
## API
|
|
|
|
### systemArchitecture()
|
|
|
|
Returns a promise for a CPU architecture name. See [`process.arch`](https://nodejs.org/api/process.html#processarch) for possible values.
|
|
|
|
### systemArchitectureSync()
|
|
|
|
Returns a CPU architecture name. See [`process.arch`](https://nodejs.org/api/process.html#processarch) for possible values.
|
|
|
|
## Note
|
|
|
|
This should really be in Node.js core, but they are [not pragmatic](https://github.com/nodejs/node/issues/17036).
