How can I use compression in Express for debugging?

What is compression in Express and how can it help with debugging?

Compression in Express reduces the size of the response body, making it faster to send data. It can help with debugging by allowing you to see the actual size of the data being sent and received, which can highlight issues with large payloads.

How do I implement compression in my Express app?

You can implement compression by using the 'compression' middleware. First, install it using npm: npm install compression. Then, require it in your app and use it as middleware like this: app.use(compression());.

Are there any specific debugging tips when using compression?

Yes, ensure to check the response headers for 'Content-Encoding' to confirm compression is applied. Also, monitor the payload size in your network tab to identify any anomalies.

Can compression affect my application's performance?

Yes, while compression can reduce the size of responses, it also adds CPU overhead. It's important to test and find a balance between speed and resource usage.
