 ### `onRequest` vs. `preHandler` hook
 
-The main difference between the `onRequest` and `preHandler` stages of the [Fastify Lifecycle](https://www.fastify.io/docs/latest/Reference/Lifecycle/) is that the body payload is not parsed in the  `onRequest` stage. Parsing the body can be a potential security risk, as it can be used for denial of service (DoS) attacks. Therefore, it is recommended to avoid parsing the body for unauthorized access.

Parsing the body can be a potential security risk, as it can be used for denial of service (DoS) attacks. Therefore, it is recommended to avoid parsing the body for unauthorized access.
 
 Using the `@fastify/auth` plugin in the `preHandler` hook can result in unnecessary memory allocation if a malicious user sends a large payload in the request body and the request is unauthorized. In this case, Fastify will parse the body, even though the request is not authorized, leading to unnecessary memory allocation. To avoid this, it is recommended to use the `onRequest` hook for authentication, if the authentication method does not require the request body, such as `@fastify/jwt`, which expects the authentication in the request header.
