Sample
CommonJS dependencies require both ssr.noExternal and ssr.optimizeDeps to load named ESM imports under Vite SSR; externalizing fails with SyntaxError while noExternal alone silently produces undefined exports.

Case
- Goal
- CommonJS dependencies require both ssr.noExternal and ssr.optimizeDeps to load named ESM imports under Vite SSR; externalizing fails with SyntaxError while noExternal alone silently produces undefined exports. HOW
- Packages
- lodash 4.17.21 vite 6.2.0
- Environment
- node
- Created
- 2026-08-15T14:40:23Z
Contract
- assert default SSR externalization rejects named imports from CommonJS modules with SyntaxError
- assert client-side optimizeDeps does not affect SSR module externalization
- assert ssr.optimizeDeps without ssr.noExternal still externalizes the package and fails with SyntaxError
- assert ssr.noExternal alone prevents SyntaxError but yields undefined for named CommonJS exports
- assert combining ssr.noExternal and ssr.optimizeDeps correctly synthesizes named and default exports
