fix: exclude test files from npm package

[developerkunal]

Changes

This PR excludes test files from the npm package build, significantly reducing the package size distributed to end users.

What changed:

• Added exclude patterns to tsconfig.cjs.json and tsconfig.esm.json to prevent test files from being compiled into the dist directory
• Excluded patterns: **/*.test.ts, **/*.spec.ts, and **/tests/**

Why this is important:

• Test files were being unnecessarily included in the npm package, inflating the package size
• Users downloading the package had to download and store ~6 MB of test files they don't need
• Both TypeScript config files are protected in .fernignore, so these changes won't be overwritten by the SDK generator

Impact:

• Package size (compressed): Reduced from 1.6 MB to 947.6 kB (41% reduction)
• Unpacked size: Reduced from 15.9 MB to 8.3 MB (48% reduction)
• File count: Reduced from 8,977 files to 8,068 files (909 fewer files)

Files modified:

• tsconfig.cjs.json - Added exclude patterns
• tsconfig.esm.json - Added exclude patterns

Note: Both files are already listed in .fernignore (lines 30-31), so these changes are safe from being overwritten during SDK regeneration.

References

• Internal investigation found that npm pack was including test files from src/management/tests/
• 536 test-related files were being included in the distributed package

Testing

Manual testing performed:

• ✅ Cleaned and rebuilt the project: rm -rf dist && npm run build
• ✅ Verified test files are excluded: npm pack --dry-run 2>&1 | grep -c "tests/" returns 0
• ✅ Confirmed package size reduction
• ✅ Verified no test directories in dist: find dist -type d -name "tests" returns empty

What was tested:

• Build process completes successfully with the exclude patterns
• Test files are not present in the compiled dist directory
• Package contents verified with npm pack --dry-run

What was not tested:

• Existing unit/integration tests were not run as this change only affects the build output, not the code functionality
• This change adds unit test coverage - N/A (build configuration change)
• This change adds integration test coverage - N/A (build configuration change)

Checklist

• I have read the Auth0 general contribution guidelines

• All existing and new tests complete without errors - Build configuration change only, no code changes
