Global Error Handling Strategies
Implement a centralized error handling mechanism to gracefully manage exceptions and provide consistent error responses.
Centralized Errors in Express
When building an API, errors are inevitable. How you handle them can drastically affect user experience and application stability.
Scattered try...catch blocks in every route can become messy and inconsistent. This lesson introduces global error handling in Express.js.
Express's Default Error Response
By default, if an error occurs in an Express route or middleware and isn't caught, Express will:
- Send a response with a
500 Internal Server Errorstatus code. - Include the error's stack trace in the response.
This default behavior is not ideal for production, as it exposes sensitive server details to clients.
