Detecting Low Power Mode in macOS with is-low-power-mode

is-low-power-mode is a tiny JavaScript library that allows you to check if a macOS system is running in low-power mode.

Developers can use this library to adjust their app’s behavior. For example, they might pause background tasks or reduce update frequencies when the system is trying to save power. This approach can lead to better battery life for users and more efficient apps overall.

How it works:

The is-low-power-mode library works by executing the pmset command on macOS systems.

The library parses the command output and searches for specific text patterns indicative of low-power mode.

If the pattern is found, the function returns true; otherwise, it returns false.

How to use it:

1. Install the ‘is-low-power-mode’ with NPM.

# NPM
$ npm install is-low-power-mode

2. Import it into your project:

import {isLowPowerMode} from 'is-low-power-mode';

3. The library includes both asynchronous and synchronous versions of the function to accommodate different application requirements.

await isLowPowerMode(): Promise<boolean>
// OR
await isLowPowerModeSync(): boolean
