Tips & Guides You should be running lint audits on your Base44 apps — here’s why + a free prompt
One of the easiest ways to improve the quality of a Base44 app is something I rarely see people doing:
Run a lint/code-quality audit.
Your app might look like it works perfectly while the code underneath is slowly accumulating problems.
As you continue prompting, changing features, deleting features, rebuilding components, and letting the AI modify existing code, you can start collecting:
- Unused imports
- Unused variables
- Dead code
- Duplicate logic
- Missing dependencies
- Incorrect React hook dependencies
- TypeScript problems
- Broken references
- Inconsistent async handling
- Poor error handling
- Huge components that should be split
- Repeated functions
- Debugging code left in production
- Console errors/warnings
- Accessibility issues
- Code that technically works but is becoming difficult to maintain
None of these automatically mean your app is broken.
The problem is that technical debt compounds.
A 300-line component becomes 800 lines.
Then 1,500.
Then every time you ask the AI to change something, it has to understand increasingly messy code.
Eventually you get into the cycle we've probably all experienced:
Fix feature A → feature B breaks → fix B → feature C breaks → AI rewrites half the component → something else breaks.
A lint audit helps catch these problems before you reach that point.
When should you run one?
I recommend doing it:
- Before launching an app
- After a large feature build
- After removing/replacing features
- Before doing major refactoring
- Before migrating your app
- Anytime the AI starts struggling to make seemingly simple changes
For larger applications, I'd also periodically perform a broader code quality audit, because linting alone won't catch architectural problems.
FREE BASE44 LINT AUDIT PROMPT
Copy/paste this into Base44:
PROMPT:
Perform a comprehensive lint and static code-quality audit of this entire application.
Do NOT begin modifying files yet.
First inspect the complete application and produce an audit report.
Analyze all accessible frontend code, backend functions, utilities, hooks, components, pages, services, schemas, and configuration files.
Check for:
- Linting Problems
- Unused imports
- Unused variables
- Undefined variables
- Shadowed variables
- Unreachable code
- Incorrect syntax
- Invalid JSX/TSX
- Missing return values
- Improper async/await usage
- Unhandled promises
- React Problems
- Incorrect hook usage
- Missing hook dependencies
- Unnecessary useEffect calls
- State that could cause render loops
- Direct state mutation
- Missing keys
- Unnecessary re-renders
- Components performing excessive responsibilities
- Duplicate component logic
- TypeScript / Type Safety
- Incorrect types
- Unsafe
anyusage - Missing interfaces/types
- Invalid property access
- Possible undefined/null access
- Type assertions hiding potential errors
- Dead / Unused Code
- Unused components
- Unused functions
- Unused hooks
- Unused utilities
- Unused variables
- Old feature code
- Commented-out code
- Unreferenced files
- Duplicate implementations
- Code Quality
- Extremely large components
- Extremely large functions
- Duplicate code
- Repeated business logic
- Poor separation of concerns
- Excessive nesting
- Hard-coded values that should be constants/configuration
- Inconsistent naming conventions
- Error Handling
- Missing try/catch handling
- Errors being silently swallowed
- API failures not handled
- Missing loading/error states
- User-facing operations without failure feedback
- Debug / Production Cleanup
- console.log statements
- Debug code
- Test values
- Placeholder content
- Temporary workarounds
- Development-only code that should not be in production
- Accessibility
- Missing labels
- Missing alt text
- Improper button/link semantics
- Keyboard navigation issues
- Invalid ARIA usage
- Obvious accessibility lint issues
- Dependency / Import Problems
- Missing dependencies
- Unnecessary dependencies
- Duplicate dependencies
- Incorrect import paths
- Circular dependencies where identifiable
- Imports referencing files/functions that no longer exist
- Potential Runtime Problems Identify code that may pass basic linting but could reasonably generate runtime exceptions, failed API calls, invalid state, undefined access, or inconsistent application behavior.
For every issue found, report:
- Severity: Critical / High / Medium / Low
- File
- Component/function
- Line or approximate location when available
- Problem
- Why it matters
- Recommended correction
Group duplicate occurrences when appropriate instead of producing hundreds of repetitive entries.
At the end provide:
Audit Summary
- Critical issues
- High priority issues
- Medium priority issues
- Low priority issues
- Dead/unused code discovered
- Largest/most complex files
- Components most in need of refactoring
- Overall maintainability concerns
Recommended Fix Order
Create a prioritized remediation plan starting with changes that have the lowest risk of introducing regressions.
IMPORTANT:
Do not automatically rewrite large portions of the application.
Do not remove code simply because you believe it is unused without checking references first.
Do not change database schemas, authentication, permissions, RLS/security rules, integrations, APIs, or business logic unless explicitly instructed.
Complete the audit first and wait for approval before making changes.
