npm install jj-envset

Usage

• <key>: The environment variable key you want to set.
• <command>: The command to execute, whose output will be saved as the value for the <key>.
• <envFile> (optional): The path to the .env file. Defaults to .env in the current directory.

JavaScript Module

import { envset } from 'jj-envset';

const key = 'HELLO_WORLD';
const command = 'echo Hello World!';
