electron-rebuild problems with MagicMirror 2.22.0

I have a docker installation running for development here on my notebook.
Everytime a module needs “npm install” I exec to the container and run the command in the container cause there will be called the correct npm and node version in the container and not the ones I currently use on my notebook.
In this case the directory structure is the same as with a locally installed MagicMirror and the postinstall script will work as excepted.

yes, will work, but all the changes in the node_modules folder of mm are gone with the next restart of the container …

@karsten13
In case of electron-rebuild this is no problem as it is only required during compile but not at runtime.

[karsten13]

@wishmaster270

o.k., but where are the compile results stored?

[wishmaster270]

@karsten13
They are stored in the node_modules folder of the module which should be persistent

Edit: Do not misunderstand me. In my opinion the best way to solve the electron-rebuild problems of a lot of modules would be to put “@electron/rebuild” as a dependency to “package.json” of MagicMirror.

thats good, so the construction with installing electron-rebuild in mm folder has no side effects and works also in a docker setup.

I don’t have a final opinion on that yet, but if so, we should put it under optionalDependencies as electron

[wishmaster270]

@karsten13

You are right. I think optionalDependencies would be a great solution. Module developers could then add a hint to run npm ci in the MagicMirror directory to their installations instructions.

As the container it self is untouched it should be no problem. It only causes @electron/rebuild to be installed the next time the script is called.

@KristjanESPERANTO but if u look at electron/rebuild after install u call electron-rebuild

still has to be installed in the base node_modules folder…

older unmaintained modules are broken either way. why I had to fork MMM-Buttons.

[sdetweil]

@wishmaster270 optional is there so that IF electron is NOT installed, the install does not fail (needed on pi0w at least)
have nothing to do w ci

my script ONLY installs prod, no dev. as 99.5% of users are users not mm developers. has nothing to do w module developers

[sdetweil]

@karsten13 and the postinstall checks for it being there, and if so skips the e-r install.

doesn’t know/care HOW it got installed before

[karsten13]

@sdetweil

you can use --omit=optional as param for npm install, I use this for my amd64 images because they are run to 99,9% with npm run server so electron is not needed

@karsten13 What are your thoughts on adding npm install @electron/rebuild --unsafe-perm; \ as part of the container image creation process to https://gitlab.com/khassel/magicmirror/-/blob/master/build/Dockerfile-debian?

@thobach

I’m trying to keep image size small … but which image are you using? latest or fat?
