SayPro List 100 code review checkpoints for SayPro’s development team from SayPro Monthly February SCMR-17 SayPro Monthly IT Services: Software development, cybersecurity, and IT support by SayPro Online Marketplace Office under SayPro Marketing Royalty
✅ Section 1: General Code Quality (1–20)
- Code is readable and consistently formatted.
- No commented-out code left in the final version.
- Follows SayPro coding standards and naming conventions.

- Reusable logic is extracted into functions or services.
- No redundant or duplicated code blocks.
- Proper file and folder organization per SayPro’s architecture.
- No magic numbers; all constants are clearly named.
- Code changes are scoped to a single responsibility/task.
- Removes obsolete files, functions, or assets.
- Uses enums or constants for repeated values.
- Uses default values in functions and destructuring.
- Avoids overengineering or premature abstraction.
- Avoids unnecessary libraries or dependencies.
- Avoids large functions—split into smaller units when needed.
- File sizes are within manageable limits (e.g., < 500 LOC per file).
- Comments are used only where necessary and explain why, not what.
- Checks for spelling errors in code, comments, and docs.
- Commit messages are clear, follow SayPro’s Git standards, and reference relevant tasks or tickets.
🔐 Section 2: Security (21–40)
- Input data is validated and sanitized.
- No direct SQL queries without prepared statements or ORM.
- Passwords or sensitive data are not logged.
- Secrets or API keys are not hardcoded.
- All external API calls are authenticated securely.
- Files uploaded are checked for size, type, and content.
- Session and cookie handling is secure (HTTP-only, secure flag).
- CORS is configured correctly for exposed endpoints.
- Proper escaping is used to prevent XSS (e.g., in HTML rendering).
- Access control checks are enforced at both UI and API levels.
- Role-based permission logic is implemented correctly.
- Dependencies are verified for vulnerabilities (Snyk, npm audit).
- No excessive exposure of internal fields in APIs.
- JSON Web Tokens (JWTs) are signed, validated, and expire correctly.
- Prevents replay attacks or predictable token generation.
- Ensures logout functionality properly invalidates sessions.
- Uses rate limiting on endpoints prone to abuse.
- Avoids displaying stack traces or system errors to users.
- Upload folders and user files are protected from public access.
- Uses HTTPS for all external communications and link references.
⚙️ Section 3: Functionality & Business Logic (41–60)
- All features meet acceptance criteria and business requirements.
- Logic reflects latest specifications or change requests.
- Edge cases and exceptions are handled gracefully.
- System behaves correctly under different user roles.
- Proper fallback or default logic is used.
- Operations are idempotent where applicable (especially APIs).
- Business rules are separated from controller logic.
- State transitions (for statuses, orders, etc.) are accurate and auditable.
- UI feedback reflects true backend outcomes (e.g., success/failure).
- APIs return meaningful status codes and structured responses.
- Transactions or multi-step operations use rollback handling.
- Asynchronous operations are monitored and managed correctly.
- UI is disabled while async operations are pending.
- Conflicting or invalid states are impossible in normal use.
- Default behavior for empty data or broken content is user-friendly.
- Sorting, filtering, and searching features are consistent.
- Timezone, date, and currency values are localized.
- Admin vs. user logic is well-isolated.
- UI and backend validations are synchronized.
- Feature toggles are used for unreleased/incomplete features.
🧪 Section 4: Testing (61–80)
- Includes unit tests for core logic.
- Includes integration tests for data flows and dependencies.
- Includes end-to-end tests for critical user flows.
- All new features are covered by tests.
- Test coverage reports meet the SayPro standard (e.g., >85%).
- No failing or skipped tests committed.
- Mocks are used for external services in tests.
- Test data is realistic and clean.
- Edge cases are included in test scenarios.
- Automation scripts are reliable and repeatable.
- No testing logic is committed in production code.
- Tests are named clearly and describe expected behavior.
- Setup and teardown scripts are optimized and reusable.
- UI components are snapshot tested if applicable.
- No flaky tests exist in the codebase.
- Large payloads are tested for performance and validation.
- Asynchronous operations are tested for timeout and retry logic.
- Test failures are logged meaningfully.
- Coverage for error scenarios is documented and enforced.
- CI/CD test results are clean with no warnings or timeouts.
🚀 Section 5: Performance & Optimization (81–100)
- Unused or redundant assets are removed.
- Lazy loading is used for heavy components or assets.
- Database queries are optimized and indexed.
- Avoids N+1 query problems.
- Pagination is implemented for large datasets.
- Data transformations are done server-side when possible.
- Caching mechanisms are applied (Redis, browser cache, etc.).
- Images are optimized and served in efficient formats (e.g., WebP).
- CSS and JS files are minified and bundled.
- Infinite scroll or virtual rendering is used where needed.
- Memory usage and CPU-intensive logic are profiled.
- Long-running processes are done in background workers.
- Frontend avoids blocking the main thread.
- Debouncing and throttling are used for user input events.
- Component re-rendering is minimized.
- API payloads are minimized and compressed.
- Large file uploads are chunked.
- Use of CDNs for static asset delivery.
- Application load time is within SayPro’s acceptable SLA.
