Implement thorough error handling that goes beyond basic logging and provides contextually accurate, actionable error messages. Error handling should include proper propagation, recovery mechanisms where appropriate, and messages that reflect the actual system state and available options.
Implement thorough error handling that goes beyond basic logging and provides contextually accurate, actionable error messages. Error handling should include proper propagation, recovery mechanisms where appropriate, and messages that reflect the actual system state and available options.
Avoid minimal error handling that only logs errors:
// Inadequate - just logs and continues
socket.on('error', (error) => console.log('socket error from wrapper', error));
Instead, implement comprehensive error handling with context-aware messaging:
// Better - proper error handling with context
socket.on('error', (error) => {
console.error('Socket connection failed:', error.message);
process.exit(1); // or appropriate recovery mechanism
});
// Context-aware error messages
if (!(await fs.promises.stat(executable)).isFile()) {
const packageManager = detectPackageManager(); // Use actual detected manager
throw new Error(`Executable does not exist. Did you update Playwright recently? Make sure to run ${packageManager} playwright install webkit-wsl`);
}
Error messages should be accurate to the current system context and provide specific, actionable guidance rather than generic assumptions about user environment or tooling.
