elliotisms/lib/exec.js

reusable atomic functions for the dumb shit i reuse all the time. only about half are jokes.

import { exec } from 'node:child_process';

const execa = async (cmdStr, cwd = process.cwd()) => {
    return new Promise((resolve, reject) => {
        // Use a regex to match either non-whitespace characters or characters within quotes
        const cmdArray = [...cmdStr.matchAll(/(?:[^\s"']+|"[^"]*"|'[^']*')+/g)].map(arg => {
            // Remove surrounding quotes from arguments
            return arg[0].replace(/^['"]|['"]$/g, '');
        });
        const command = cmdArray.shift();
        const cmd = exec(cmdStr, { cwd });
        
        let allData = '';
        let allError = '';

        cmd.stdout.on('data', (data) => {
            allData += data
        });

        cmd.stderr.on('data', (data) => {
           
            allError += data
        });

        cmd.on('close', (code) => {
            if (code === 0) {
               
                resolve(allData);
            } else {
                reject(new Error(`Command failed with code ${code}: ${allError}, ${allData}`));
            }
        });

        cmd.on('error', (error) => {
            reject(new Error(`Spawn error: ${error.message}`));
        });
    })
};

export default execa;
