Proposed fix: [Node.js native TypeScript] 'SyntaxError [ERR_UNSUPPORTED_TYPESCRIPT_SYNTAX]: TypeScript enum is not supported in strip-only mode' — type stripping on by default (22.18+/23.6+); enums/na
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Either keep code erasable (replace enums with const objects + union types; use import type; explicit .ts extensions; subpath imports '#...' instead of tsconfig paths; enable erasableSyntaxOnly/verbatimModuleSyntax in tsconfig to catch issues), or use a third-party transpiler (tsx, tsc build) for full TypeScript. For tools broken by default stripping, NODE_OPTIONS=--no-experimental-strip-types was reported as a workaround.
Option: Make code erasable or transpile [evidence: official_recommended_action]
Applies when: Running TS directly on Node
Steps:
1. Set "erasableSyntaxOnly": true and "verbatimModuleSyntax": true in tsconfig and run tsc --noEmit to find offending syntax
2. Replace enums with 'as const' objects + union types; use import type; add .ts extensions to relative imports
3. Or run via tsx / precompile with tsc when full TS features are needed
Expected: Files load under native type stripping, or run through a transpiler
