run node project command code example

Example 1: serve build node npm

# in terminal cd to project root dir
# to build project:
npm run build
# to serve/host project locally:
serve -s ./build

Example 2: node run command

// Run a command asynchronously
const { spawn } = require('child_process');
const dir = spawn('cmd', ['/c', 'dir']);

dir.stdout.on('data', data => console.log(`Stdout: ${data}`));
dir.stderr.on('data', data => console.log(`Stderr: ${data}`));
dir.on('close', code => console.log(`Exit code: ${code}`));

// Run a command synchronously
const { spawnSync } = require( 'child_process' );
const dir = spawnSync('cmd', ['/c', 'dir']);

console.log(`Stdout: ${dir.stdout.toString()}`);
console.log(`Stderr: ${dir.stderr.toString()}`);

const app = express();
app.use(express.static('public'));// to connect with frontend html
