Complete Wix app development audit and launch checklist

This final lesson brings everything together into a definitive 150-point scored audit checklist covering every stage of Wix app development, from code quality and security to UX, performance, App Market listing and growth strategy. Use this checklist before every app submission and as a quarterly health check for published apps. Each section is scored independently so you can identify exactly where your app needs improvement.

Section 1: Code Quality and Architecture (25 Points)

• (3 pts) TypeScript strict mode enabled with no "any" types in production code
• (3 pts) Clear separation of concerns: UI components, business logic, API calls and utilities in separate modules
• (3 pts) All API calls wrapped in proper error handling with typed error responses
• (2 pts) No console.log statements in production code - use structured logging utility
• (2 pts) Environment variables used for all configuration - no hard-coded values
• (3 pts) All dependencies pinned to specific versions in package.json (no ^ or ~ ranges)
• (3 pts) No known security vulnerabilities in dependencies (run npm audit)
• (3 pts) Clean Git history with meaningful commit messages and no committed secrets
• (3 pts) README.md with setup instructions, architecture overview and development guide

Section 2: Security and Data Privacy (20 Points)

• (4 pts) All sensitive data (API keys, tokens, secrets) stored server-side only - never exposed in frontend code
• (3 pts) Input validation on all user inputs: sanitise, validate types, enforce length limits
• (3 pts) No XSS vulnerabilities: all user-generated content properly escaped before rendering
• (3 pts) API endpoints validate authentication and authorisation for every request
• (2 pts) HTTPS enforced for all external API calls - no HTTP connections
• (2 pts) Wix Secrets Manager used for storing third-party API keys
• (3 pts) Data handling compliant with GDPR: privacy policy link in app, data deletion on uninstall option

Section 3: Performance and Loading Speed (20 Points)

• (4 pts) Dashboard pages load in under 2 seconds on standard connection speed
• (4 pts) Site widgets render in under 1 second with no visible layout shift (CLS < 0.1)
• (3 pts) JavaScript bundle size under 200KB gzipped for site widgets
• (3 pts) Images optimised: WebP format, lazy loaded, responsive sizes, under 100KB each
• (3 pts) API calls minimised: batch requests where possible, cache responses that do not change frequently
• (3 pts) No memory leaks: event listeners cleaned up, intervals cleared, subscriptions unsubscribed on unmount

Section 4: UX, Design and Accessibility (25 Points)

• (3 pts) Wix Design System components used for all dashboard pages - consistent with platform UI
• (3 pts) Site widgets responsive from 280px to 1200px width with no breaking layouts
• (3 pts) At least 3 design presets available for site widgets (Light, Dark, Minimal)
• (3 pts) First-time user experience: guided setup wizard that reaches first value in under 60 seconds
• (3 pts) Empty states designed for all screens where data might not exist yet
• (2 pts) Loading states shown for all async operations with appropriate skeleton or spinner UI
• (2 pts) Error messages are user-friendly, explain what went wrong and suggest a fix
• (2 pts) WCAG 2.1 AA colour contrast compliance on all text and interactive elements
• (2 pts) Full keyboard navigation support: tab order logical, focus visible, escape closes modals
• (2 pts) Screen reader compatibility: aria-labels on icons, semantic HTML, announced state changes

Section 5: App Market Listing and Growth (30 Points)

• (4 pts) App name contains primary keyword, under 30 characters, clear value proposition
• (4 pts) Description opening 150 chars optimised for search: primary keyword + benefit statement
• (4 pts) 5-8 feature bullets with action verbs and secondary keywords naturally included
• (3 pts) 4-6 professional screenshots with annotation text, consistent design, mobile view included
• (3 pts) Demo video (30-60 seconds) showing install to first result flow
• (3 pts) Demo site set up with realistic data and testing instructions for Wix reviewers
• (3 pts) Pricing strategy defined: free tier meaningful, 2-3 paid tiers, annual discount offered
• (3 pts) Review generation strategy: in-app prompt at success milestone, response plan for all reviews
• (3 pts) Content marketing plan: landing page, comparison posts, tutorial content targeting Wix users

Scoring Your App

Add up your points across all five sections to get your total score out of 150. Use these thresholds to gauge your app's readiness.

• 130-150 points: Excellent - ready for submission with high confidence of first-time approval
• 100-129 points: Good - address the gaps before submitting, most likely approved with minor feedback
• 70-99 points: Needs work - significant gaps that will likely result in rejection. Focus on the lowest-scoring section first.
• Below 70 points: Not ready - return to the relevant lessons in this module and address fundamental issues before proceeding

Post-Launch Quarterly Audit

Re-run this audit every quarter for published apps to ensure quality does not degrade over time.

Quarterly audit process for published Wix apps

• Re-score every section of this checklist. Note which areas have improved or declined since the last audit.
• Review your App Market analytics: install trend, retention rates, rating changes and revenue metrics.
• Check for new Wix API capabilities or design system updates that you can leverage in your next update.
• Review and respond to all new user reviews. Identify recurring feature requests or bug reports.
• Update your app listing screenshots and description to reflect new features and improvements.
• Run npm audit to check for new security vulnerabilities in dependencies and update as needed.
