Keeping frontend errors useful for developers

Context

Frontend errors in the application were difficult to investigate afterward because the information visible to the user didn’t always allow identifying the root cause.

Problem

When errors occurred in production, the information available to developers was insufficient for effective debugging. User-facing error messages lacked technical context.

Approach

I designed a mechanism to collect relevant error information while maintaining separation between what’s shown to the user and what’s used internally for investigation.

Solution

Implemented an error reporting system that:

• Captures error context and stack information
• Collects browser and environment data
• Stores errors with timestamps
• Provides meaningful messages to users
• Preserves technical details for developers

Result

Errors could be logged with greater context, facilitating subsequent analysis and diagnosis, while users received clear and helpful error messages.
