feat(puppeteer): Cleanup node_modules

[lslezak]

Problem

• The Puppeteer node_modules directory is huge

Solution

• Delete the not needed content from node_modules
• Inspired by node-prune tool (written in Go, not much suitable to run during RPM build, I rewrote that to shell)

Testing

• Tested manually

Numbers

• The node_modules directory size went down from 39MB to 15MB (-62%)
• The built RPM size went down from 3.5MB to 1.9MB (-46%)
• I expect the Live ISO size reduction similar to the RPM reduction

I know that list is just copied, but can we legally delete such license files? maybe if there are identical, we can just run deduplication in rpm build?

[lslezak]

Oh, good point. As we already run the deduplication in RPM we could keep them. I'll check how much the size changes...

[lslezak]

With included license files the RPM size increased by about 24kB, so I'll rather keep them.

[jreidinger]

I kind of expect that it will run internally that node-prune.sh..so just one command will be enough to cleanup pupeteer modules.

[lslezak]

Both commands are started in the agama-integration-test scripts which installs the NPM packages and runs the tests. Normally you should not need to run them separately.

[jreidinger]

should we run it also for agama web directory?

[lslezak]

Agama-web uses webpack which already bundles only the needed files into the target JS file. It would not help there.

And we do obfuscation and minification as well...
