Just discovered that the npm dependencies are actually installed 3x.
First here using the Makefile

news/Makefile

Line 87 in 9c100f2

$(npm) ci

and then twice here as part of the prebuild script (ci does the same thing as install, but more "carefully")

news/package.json

Line 6 in 9c100f2

"prebuild": "npm install && npm ci",

I would recommend to remove the "prebuild" step but I'm not sure whether this is the preferred way.
Alternatively it could be renamed to "predev" to only run when executing npm run dev but I don't think that an automated step should execute npm install, which also could modify the package(-lock).json.

I don't see the need for npm install at all in these scripts.

It should just be npm ci.

I think I would prefer to take the npm ci comand out of the makefile and leave that in the package.json.

Thanks for checking this @anoymouserver.

I saw druing testing and building the app that npm ran multiple times but was too lazy to check why.

Now like this much faster build time 👍
