```typescript
export default defineNuxtConfig({
  modules: ["@nuxt3-auth-example/request-log-starter"],

  requestLog: {
    filter: (event) => {
      // Skip logging for static assets
      if (event.path.startsWith("/assets/") || event.path.startsWith("/_nuxt/")) {
        return false;
      }
      return true;
    },
  },
});
```
