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 CLI project setup and code quality through to security, performance, UX, 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. The Wix App Market reaches over 230 million users, and every point on this checklist is an investment in your share of that audience.

Pre-Build Checklist: CLI Setup and Project Configuration

Before writing a single line of application code, your project scaffolding must be correct. Errors at the configuration level cause cascading problems throughout development and can result in submission failures that are difficult to diagnose. Run through these setup checks as the very first step.

Wix CLI project setup verification

• Confirm the project was created using npm create @wix/app. Do not manually scaffold a Wix app project from scratch as you will miss critical wiring
• Verify Node.js version 18 or higher is in use: run node --version in the project directory
• Confirm wix.config.json exists at the project root and contains your correct App ID from the Wix Developer Centre
• Check that all required permission scopes are declared in wix.config.json under the permissions field. Only include scopes your app actually uses
• Run npm install and verify there are no peer dependency conflicts or unresolved packages
• Run npm run dev and confirm the development server starts without errors and opens a valid preview URL
• Navigate to dev.wix.com/apps and confirm your app appears in the list with a Development status linked to the correct developer account
• Verify the src/dashboard/, src/site/, and src/backend/ directory structure is present and matches the component types declared in wix.config.json

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

• (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)

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.
