Replit Agent issues we find in JavaScript projects
Problems specific to Replit Agent's code generation patterns when building JavaScript apps.
Secrets stored in Replit environment
API keys and credentials stored in Replit's secrets manager don't transfer when you export the project. Developers often hardcode them as a workaround, creating security risks.
No HTTPS or security headers
Replit's development environment doesn't enforce HTTPS or set security headers. Apps deployed without proper configuration are vulnerable to man-in-the-middle attacks.
Database connection instability
Replit's hosted databases can disconnect unexpectedly. Without connection pooling and retry logic, apps crash or lose data during these interruptions.
JavaScript add features issues we check for
Add Features-specific JavaScript problems that need attention before production.
Loose equality comparisons
Using == instead of === leads to type coercion bugs where '0' == false, null == undefined, and other non-obvious truthy/falsy comparisons cause silent logic errors.
Unhandled promise rejections
Async functions without try/catch or .catch() handlers cause unhandled rejection warnings and silent failures in production.
Global variable leaks
Missing 'const' or 'let' declarations create implicit globals that pollute the global scope and cause unpredictable behavior across modules.
