Refactor Code for your Databutton-built FastAPI app
Expert refactor code for FastAPI apps built with Databutton. We audit Databutton-generated FastAPI code for refactor code issues. From $19.
Databutton issues we find in FastAPI projects
Problems specific to Databutton's code generation patterns when building FastAPI apps.
SQL injection in AI-generated query strings
Databutton's generated FastAPI endpoints sometimes build SQL queries using f-strings or string concatenation with user-supplied parameters, bypassing parameterized query protections entirely.
No authentication on data API endpoints
Data pipeline endpoints are frequently generated without authentication middleware, exposing raw database access and sensitive business metrics to anyone who discovers the API URL.
Unhandled data type mismatches crashing pipelines
Generated data processing code assumes clean input schemas. When upstream data contains nulls, type changes, or unexpected formats, pipelines throw unhandled exceptions and fail silently.
FastAPI refactor code issues we check for
Refactor Code-specific FastAPI problems that need attention before production.
Blocking calls inside async endpoints
Synchronous database calls, file operations, or HTTP requests inside async def endpoints block the entire event loop, making your API unresponsive under load.
Pydantic models without validation constraints
Request models that accept any string length, any number range, and any format. No Field() constraints, so invalid data flows through your system.
No rate limiting on public endpoints
Public API endpoints (especially AI wrapper endpoints that call OpenAI or similar) have no rate limiting, so a single user can run up massive costs.
