Hello 
I saw that aws-sdk is taking huge part of my application.
Do you have any ideas how I can optimise it?
I’m using aws-sdk for upload images to s3 (server side).
Ok, I came to it myself
I used a dynamic import
const AWS = await import('aws-sdk');
Now my whole app is less by half
if you only use it on the server, make sure its not imported on the client.
If you replace it with a dynamic import, but this import still gets called on the client somehow, you will still load it at some point 
if that’s on startup, it will still use the users bandwidth.
Maybe add a debugger or console statement right before the import and check whether that appears on the client or not. if not, you are fine 
Hi @macrozone, thank you for your message.
I’ve checked it twice and everything is running only on server side.
