angular web app - include library licenses

问题

I have an angular-cli with many libraries. To include the licenses for these I include all of the LICENSE and package.json files from node_modules in the build.

"assets": [
    {
        "glob": "**/package.json",
        "input": "../node_modules/",
        "output": "./licenses"
    },
    {
        "glob": "**/LICENSE*",
        "input": "../node_modules/",
        "output": "./licenses"
    }
]

However this adds ~4000 individual files to the output and adds time to the build and upload, and some of the libraries are build/development tools not used in the source. I'm about to zip the licenses in a pre-build process as a quick solution.

This seems like a common issue. Is there a smart tool for this, that packages in a way, only the used licenses?
