bare-os

Reference for bare-os: operating-system utilities for Bare—platform and CPU info, directories, memory and load, process priority, and environment access.

stable

bare-os provides operating-system utilities for Bare. The API follows the Node.js os module, with extra helpers for the current process and environment. It's a native addon and requires Bare >=1.14.0. Many bare-* modules depend on it.

npm i bare-os

Usage

const os = require('bare-os')

console.log(os.platform(), os.arch())
console.log('home:', os.homedir())
console.log('cpus:', os.cpus().length)

API

Constants

`os.constants` · `os.EOL` · `os.devNull`

OS constant tables, the end-of-line marker, and the null-device path.

Platform and machine

`os.platform()` · `os.arch()` · `os.type()` · `os.version()` · `os.release()` · `os.machine()` · `os.endianness()`

Identify the operating system, architecture, kernel, and byte order.

`os.hostname()` · `os.networkInterfaces()` · `os.availableParallelism()`

Host name, network interfaces, and the number of parallel units of execution.

Directories

`os.cwd()` · `os.chdir(dir)` · `os.tmpdir()` · `os.homedir()` · `os.execPath()`

Get or change the working directory, and resolve the temp, home, and executable paths.

Process and users

`os.pid()` · `os.ppid()` · `os.kill(pid[, signal])`

Process IDs, and signal delivery.

`const info = os.userInfo([uid])` · `os.groupInfo([gid])`

User and group information.

`os.getProcessTitle()` · `os.setProcessTitle(title)` · `os.getPriority([pid])` · `os.setPriority([pid, ]priority)`

Read or set the process title and scheduling priority.

Resources

`os.cpus()` · `os.cpuUsage([previous])` · `os.threadCpuUsage([previous])` · `os.resourceUsage()` · `os.loadavg()` · `os.uptime()`

CPU topology, CPU-time and resource accounting, load averages, and uptime.

`os.memoryUsage()` · `os.freemem()` · `os.totalmem()` · `os.availableMemory()` · `os.constrainedMemory()`

Process and system memory figures.

Environment

`os.getEnvKeys()` · `os.getEnv(name)` · `os.hasEnv(name)` · `os.setEnv(name, value)` · `os.unsetEnv(name)`

Direct access to environment variables. The higher-level bare-env wraps these into a process.env-style object.
