cjs-esmodule-interop

Detect CJS files using __esModule interop pattern that may cause inconsistent bundler behavior

Property	Value
Rule ID	exports/cjs-esmodule-interop
Category	exports
Severity	🟡 warning
Fixable	No

What it Checks

CJS files that set __esModule = true can behave differently across bundlers (webpack vs esbuild vs Rollup). This pattern should be avoided.

Configuration

Disable this rule:

tspub check --ignore-rules "exports/cjs-esmodule-interop"

Or in tspub.config.ts:

export default {
  check: {
    severityOverrides: {
      "exports/cjs-esmodule-interop": "off",  // or "warning", "error", "info"
    },
  },
};
