Rendering takes too long

[RadouaneRoufid]

Hi,

I would like to start with great thanks for your wonderful work.

I have a angular app with a Spring boot backend. I use your solution to implement SSR. The solution works great, but the first load takes about 1 minute. I don't really understand why.

On server start up, I have the following warning ;

Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library /home/me/libj2v8_linux_x86_64.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

And the following logs when I try to reach "/".

[Error]
ERROR [Error]
ERROR [Error]

Any explanation of why my rendering takes too long ?

Thank you.

Hey Radouane

The very first time the J2V8 render is started, it will download the J2V8 DLL and place it in your home directory - after that it will just look for the DLL and use it. Is this DLL somehow deleted from time to time, e.g. anti virus software?

If not, can you share a reproducible example (Git repo) + information about your system (OS etc) so I can try to reproduce the problem?

Best,
Simon

Thank you. I will check that and share a reproducible repo.

A simple angular app works fine with ssr. I will try to add some complexity to reproduce my problem.

The problem was due to ifvisible. Putting it likle below solved the issue :

 if (isPlatformBrowser(this.platformId)) {
            ifvisible.on('wakeup', () => {
                this.countConversation();
            });
        }

Yeah that make sense, because the "screen visible" event will never occur. But still it's strange that registering the listener works at all (Because there is no client DOM)

I'm using domino to fake DOM. It can explain why the listener worked.
