const { logger } = require('@parcel/utils');
logger.info('This is an info message');
logger.warn('This is a warning message');
logger.error('This is an error message');
Process Management
This feature allows you to execute shell commands and manage processes. The code sample demonstrates running a shell command and logging its output.
const { exec } = require('@parcel/utils');
async function runCommand() {
const { stdout, stderr } = await exec('echo Hello, World!');
console.log('stdout:', stdout);
console.log('stderr:', stderr);
}
runCommand();
