TypeScript app built with GitHub Copilot? Let’s review it.
Expert code review for TypeScript apps built with GitHub Copilot. We find GitHub Copilot-specific bugs, fix TypeScript security issues, and optimize performance. From $19.
GitHub Copilot issues we find in TypeScript projects
Problems specific to GitHub Copilot's code generation patterns when building TypeScript apps.
Insecure code patterns from training data
Copilot sometimes suggests patterns from its training data that are known to be insecure — like using eval(), innerHTML, or outdated crypto functions.
Hardcoded secrets in suggestions
Copilot occasionally suggests placeholder API keys or credentials that look real and get committed to version control.
Inconsistent code style across files
Different completions use different patterns — sometimes callbacks, sometimes async/await, sometimes .then(). The codebase becomes inconsistent over time.
Subtly incorrect logic
Copilot completions often look correct but contain off-by-one errors, wrong comparison operators, or missed edge cases that cause intermittent bugs.
TypeScript issues we check for
Common TypeScript problems that affect production readiness.
Excessive use of 'any' type
AI tools use 'any' to bypass type errors instead of defining proper types, removing all the safety benefits TypeScript provides.
Missing strict mode
tsconfig.json without strict mode enables sloppy type checking that allows null errors and implicit any types.
Type assertions instead of type guards
Using 'as' casts to force types instead of runtime checks, causing crashes when data doesn't match the asserted type.
Incorrect generic implementations
Overly complex or incorrect generic types that confuse rather than help, making the code harder to maintain.
