How to check if I'm in SSR or SSG mode?

[tranquil fable]

Some of my pages are in SSR mode, some are in SSG mode. I have a component that should behave differently, if the result will be immediately displayed to the user, and when it will be stored and displayed to the user much later. How can I check for that?

I'm looking for something like this:

if(import.meta.env.SSG) // is there a check similar to this?
{
    // code
}

the import.meta are fixed and do not change in each page. Are you using prerender ? https://docs.astro.build/en/guides/server-side-rendering/#opting-in-to-pre-rendering-in-server-mode why not pass that variable to your components then ?

Thanks for the response. Yes, using prerender. I think passing down prerender through the component tree could bloat the props. I decided to go with environment variables and accessing them via process.env

You can use this cool package to get fine grained info

prerender could be set per page, in case you have both pages types, while env var is fixed.
