What considerations should be made while implementing asynchronous middleware in Express.js?
- Asynchronous middleware should use the await keyword to ensure proper execution flow.
- Asynchronous middleware should always return a Promise or use a callback.
- Asynchronous middleware should not be used in Express.js as it can lead to performance issues.
- Asynchronous middleware should use the sync keyword to ensure proper execution flow.
When implementing asynchronous middleware in Express.js, it's crucial to ensure that the middleware either returns a Promise or uses a callback to signal when it has completed its work. This is necessary to prevent premature termination of the request-response cycle and maintain proper error handling. Using await is a common approach to handling asynchronous operations.
