I Swallowed My Errors for 6 Months
I thought my error handling was good.
I used try/catch blocks. I logged to the console. I used a Sentry dashboard.
My users still hit broken flows. Files vanished. Payments went through without confirmation. Forms failed silently.
The problem was not failing to catch errors. The problem was catching them and doing nothing.
I had comments in my code like this: // TODO: handle this better
That comment stayed there for 6 months.
When an upload failed, the user saw a loading spinner that never stopped. They had no idea something went wrong. They tried again and again. Then they gave up.
I checked our analytics after a customer complained. I found these numbers:
• 23% of file uploads failed silently. • Users tried to retry an average of 2.7 times. • Our dashboard showed a healthy status because we caught all errors.
We were running a silent disaster. Our dashboard was green, but our users were frustrated.
I replaced every silent catch with a new pattern. I now categorize errors by type:
• Network errors trigger a retry dialog. • Permission errors show a guide. • Unknown errors show a clear message and log context.
The results changed everything:
• Silent upload failures dropped from 23% to 0.4%. • User-reported upload issues dropped 89%. • Support tickets about missing files dropped from 15 per week to 1 per week.
The biggest win was visibility. Our team knows about failures immediately. We do not wait for angry emails.
Error handling is not about preventing crashes. It is about making failures visible to users and teams.
A crash is honest. A silent failure is a lie.
When you write a catch block, ask yourself two questions:
- Who needs to know if this fails?
- What should they do next?
If your answer is "nobody," you have a problem.
