Add Features for your Supermaven-built JavaScript app

Expert add features for JavaScript apps built with Supermaven. We audit Supermaven-generated JavaScript code for add features issues. From $19.

Supermaven issues we find in JavaScript projects

Problems specific to Supermaven's code generation patterns when building JavaScript apps.

highBugs

Fast completions accepted without review introduce subtle type errors

Supermaven's speed is its core advantage, but it encourages accepting completions quickly. TypeScript type errors, incorrect function signatures, and wrong argument orders frequently slip through when developers tab-accept completions at high speed.

highSecurity

Security-sensitive code patterns completed without security review

In security-critical code paths like authentication, token validation, and database queries, Supermaven's completions can introduce subtle vulnerabilities — such as completing a SQL query without parameterization or missing a signature verification step.

mediumCode Quality

Existing codebase anti-patterns replicated across new files at high velocity

Supermaven learns from your codebase, which means bad patterns — deprecated APIs, insecure functions, or architectural mistakes — get propagated to new code rapidly due to how quickly completions are accepted.

JavaScript add features issues we check for

Add Features-specific JavaScript problems that need attention before production.

bugs

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.

bugs

Unhandled promise rejections

Async functions without try/catch or .catch() handlers cause unhandled rejection warnings and silent failures in production.

bugs

Global variable leaks

Missing 'const' or 'let' declarations create implicit globals that pollute the global scope and cause unpredictable behavior across modules.
