How to check if component is being server side rendered

[serendipity1004]

I am currently working on a project that uses Apollo GraphQL and NextJS. I have structured the project quite commonly by having components folder and containers folder where container folders include Apollo states. At first, I thought it would be possible to call getServerSideProps from the components and containers but it doesn't seem to be the case. So currently I am calling the queries in the page that uses the containers and using useQuery hook in the container to retrieve the state. Then I begin to wonder if the container will be server rendered or not. How do I check if a component is being fully server rendered with the states that I expect to be present?

Yes, getServerSideProps should be used in Pages only.

Then I begin to wonder if the container will be server rendered or not.

When you use getServerSideProps, your html is generated on each request.

Please take a look at the docs for detailed information.
