What it Checks

The "module" field is a convention for bundlers to find the ESM entry point. When it points to a CommonJS file, bundlers cannot tree-shake the package effectively.

Configuration

Disable this rule:

tspub check --ignore-rules "metadata/module-esm"

Or in tspub.config.ts:

export default {
  check: {
    severityOverrides: {
      "metadata/module-esm": "off",  // or "warning", "error", "info"
    },
  },
};
