Expert add features for JavaScript apps built with Devin. We audit Devin-generated JavaScript code for add features issues. From $19.
Devin issues we find in JavaScript projects
Problems specific to Devin's code generation patterns when building JavaScript apps.
Autonomous security decisions
Devin makes security-related decisions without human review — choosing auth strategies, setting permissions, and configuring access controls that may be inadequate.
Compounding architectural errors
When Devin makes an early architectural mistake, it builds subsequent features on top of it. By the time you notice, the issue is deeply embedded in the codebase.
Workarounds instead of fixes
When Devin encounters an error, it sometimes adds workarounds that mask the root cause rather than fixing the underlying issue.
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.
