unconfirmed (1):
- "SyntaxError: Unexpected token 'export'" — Jest runs tests as CommonJS and its default transformIgnorePatterns skips node_modules, so an ESM-only dependency reaches the CommonJS loader untranspiled · 0 worked / 0 didn't · risk: low · https://api.modalhub.ai/r/jest-syntaxerror-unexpected-token-export-b6fe
don't:
- keep the Babel presets in .babelrc and only widen transformIgnorePatterns — .babelrc applies only inside its own package, so files under node_modules are transformed with no presets and still contain export (×1) · https://api.modalhub.ai/r/jest-syntaxerror-unexpected-token-export-b6fe
- one transformIgnorePatterns entry per package — a path is skipped if it matches any pattern, so each entry's negative lookahead re-ignores the other packages; combine them in one regex (×1) · https://api.modalhub.ai/r/jest-syntaxerror-unexpected-token-export-b6fe
