NodeJs/NestJs which directory to install on Unix

Hi I have nodejs/nestjs microservice running in forever. I have installed in /home directory. I Have been reading around and home is not the correct place for this to be installed.
What is the correct directory to install it into? I is /srv or /usr/local or something else completely?
I think the best directory for things like that is /opt
You can read more about /opt and whole Filesystem Hierarchy here:

Cant remove node_modules file with .staging folder inside

I am facing an issue whilst trying to get rid of a folder inside of my node_modules folder. I click delete nothing happens, somethings preventing it from being removed. I have looked everywhere and can't seem to find a solution.
Any help would greatly be appreciated.
I had the same issue on my linux machine. Managed to delete the node_modules/.staging folder by .... removing my hard drive and deleting it on another pc. No node process was running on either machines. In the 4 years working with node I spent more time trying to fix it.
Solution that i found "I had Antivirus installed on my pc ,which was unknowingly using the files from node_modules folder".
I uninstalled the antivirus or u can change permission setting from antivirus setting option (depends on which antivirus u have).Now i am able to delete node_modules folder.

CentOs7 server doesn't read htaccessfile

I've reinstalled and configured my Centos7 server.
The .htaccess file always worked fine and I didn't changed anything to it.
But now the server doesn't read the file.
The /var/www/html/ folder has 777 rights.
Anyone has an idea how to solve this problem?
Searched for hours but can't find any solution.

Jpegoptim caused images to disappear

I finally figured out how to get jpegoptim properly installed on my Centos 6 system and ran the command on a larger folder of images like this
jpegoptim *.jpg --strip-all
Now none of the images appear on my website! They are still in the folder and considerably compressed, but they don't appear to be accessible. I am assuming this must be a permissions issue? Has anybody experienced this?
Okay, I figured this out. For some reason, jpegoptim changes the permissions on the file when you run it. After changing the permissions to 755 (-rwxr-xr-x) using the command chmod -R 755 [containing_folder] the images are now visible again.

Completely missing FSTAB

I recently found out that one of our servers has lost (probably someone deleted it) the /etc/fstab file, it's a Fedora Core 6.
Is there anything we can do to rebuild the fstab without a copy?
If system is still running you can get a copy of fstab from file /proc/mounts.
