Adding Vitest to your Databutton app? Let us review it.
Expert review for Vitest integrations built with Databutton. We fix Databutton-generated Vitest code for security, error handling & production readiness. From $19.
Common Databutton issues affecting integrations
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.
Vitest issues we find in Databutton apps
Mocking modules incorrectly with vi.mock()
AI-generated tests use vi.mock() with incorrect factory functions, missing auto-mock setup, or mock implementations that don't match the module's actual interface.
Only testing the happy path
Generated tests verify that functions work with valid input but skip error cases, edge cases, boundary values, and empty or null inputs.
Test isolation broken by shared mutable state
AI tools set up mock state in beforeAll instead of beforeEach, or modify shared variables across tests without resetting them, causing order-dependent test failures.

Frequently asked questions
Can you review my Databutton-built Vitest integration?
Yes. We regularly audit Vitest integrations in Databutton-built apps. We check for proper error handling, security best practices, and production-ready configuration.
What Vitest issues does Databutton typically create?
Common issues in Databutton-generated Vitest code include: mocking modules incorrectly with vi.mock(), only testing the happy path, test isolation broken by shared mutable state. We fix all of these in our code review.
How much does it cost to fix my Vitest integration?
Start with our code audit ($19) to get a complete list of Vitest issues. Most integration fixes are included in our Fix & Ship plan ($199). For complex integrations, we provide a custom quote after the audit.
What Vitest best practices does Databutton typically miss?
AI tools often skip webhook signature verification, proper error handling for API failures, retry logic with exponential backoff, and secure token storage for Vitest. Our review checks all of these and provides specific fixes.
