+# Consistent Node Export Test
+
+This test "app" ensures that we consistently re-export exports from `@sentry/node` in packages depending on
+`@sentry/node`.
+
+## How to add new package
+
+1. Add package as a dependency to the test app
+2. In `scripts/consistentExports.ts`:
+   - add namespace import
+   - add `DEPENDENTS` entry
+   - add any ignores/exclusion entries as necessary
+   - if the package is still under development, you can also set `skip: true`
+
+## Limitations:
+
+- This script only checks top-level exports for now (e.g. `metrics` but no sub-exports like `metrics.increment`)
+- This script only checks ESM transpiled code for now, not CJS
