wix-cli-app-validation（WIX CLI 应用 validation）

Wix App Validation

Validates Wix CLI applications through a four-step sequential workflow: package installation, TypeScript compilation check, build, and preview.

Validation Workflow

Execute these steps sequentially. Stop and report errors if any step fails.

Step 1: Package Installation

Ensure all dependencies are installed before proceeding with the build.

Detect package manager:

• Check for package-lock.json → use npm
• Check for yarn.lock → use yarn
• Check for pnpm-lock.yaml → use pnpm
• Default to npm if no lock file is found

Run installation command:

# For npm
npm install

# For yarn
yarn install

# For pnpm
pnpm install

Success criteria:

• Exit code 0
• All dependencies installed successfully
• No missing peer dependencies warnings (unless expected)
• node_modules directory exists and contains expected packages

On failure: Report the installation errors, check the debug log for detailed diagnostics, and stop validation. Common issues:

• Network connectivity problems
• Corrupted lock files
• Version conflicts
• Missing Node.js or package manager

Step 2: TypeScript Compilation Check

Run TypeScript compiler to check for type errors.

Full project check:

npx tsc --noEmit

Targeted check (specific files/directories):

When validating after implementing a specific extension, you can run TypeScript checks on just those files:

# Check specific directory
npx tsc --noEmit src/extensions/dashboard/pages/survey/**/*.ts src/extensions/dashboard/pages/survey/**/*.tsx

# Check dashboard pages only
npx tsc --noEmit src/extensions/dashboard/pages/**/*.ts src/extensions/dashboard/pages/**/*.tsx

# Check site widgets only
npx tsc --noEmit src/extensions/site/widgets/**/*.ts src/extensions/site/widgets/**/*.tsx

# Check dashboard modals only
npx tsc --noEmit src/extensions/dashboard/modals/**/*.ts src/extensions/dashboard/modals/**/*.tsx

# Check backend only
npx tsc --noEmit src/extensions/backend/**/*.ts

When to use targeted checks:

• After implementing a single extension (faster feedback)
• When debugging type errors in a specific area
• During iterative development

When to use full project check:

• Before final validation
• When changes affect shared types
• Before building/deploying

Success criteria:

• Exit code 0
• No TypeScript compilation errors
• All type checks pass

On failure: Report the specific TypeScript errors and stop validation. Common issues:

• Type mismatches between expected and actual types
• Missing type declarations for imported modules
• Incorrect generic type parameters
• Properties not existing on declared types
• Incompatible function signatures

Step 3: Build Validation

Run the build command and check for compilation errors:

npx wix build

Success criteria:

• Exit code 0
• No TypeScript errors
• No missing dependencies

On failure: Report the specific compilation errors, check the debug log for detailed diagnostics, and stop validation.

Step 4: Preview Deployment

Start the preview server:

npx wix preview

Success criteria:

• Preview server starts successfully
• Preview URLs are generated (both site and dashboard)

URL extraction: Parse the terminal output to find both preview URLs. Look for patterns like:

• Site preview: Site preview: https://... or Site URL: https://...
• Dashboard preview: Dashboard preview: https://... or Preview URL: https://... or Your app is available at: https://...

Extract both URLs and provide them to the user for manual verification.

On failure: Report the preview startup errors, check the debug log for detailed diagnostics, and stop validation.

Validation Report

After completing all steps, provide a summary:

Pass:

• Dependencies: ✓ All packages installed successfully
• TypeScript: ✓ No compilation errors
• Build: ✓ Compiled successfully
• Preview: ✓ Running at [URL]

Fail:

• Identify which step failed
• Provide specific error messages
• Suggest remediation steps

Debug Log on Errors

When a validation step fails (non-zero exit code, error output, or the CLI crashes/hangs), check .wix/debug.log in the project root for the full error trace. Only read this file when errors occur — skip it when steps pass or when the terminal output already makes the error clear (e.g. a straightforward TypeScript type error).

The .wix/ directory is automatically created by the Wix CLI and contains internal configuration and log files. Don't edit it, but reading debug.log for troubleshooting is expected.

Read: .wix/debug.log

# If the file is large, read the last 100 lines for the most recent errors
Read: .wix/debug.log (with offset to the end)
