custom values for --include and --omit

[trusktr]

Given this package.json:

{
  "dependencies": {...},
  "devDependencies": {...},
  "fooDependencies": {...},
}

I want to be able to do this:

npm clean-install --include foo

which would install only dependencies and fooDependencies, but not devDependencies.

This could be useful for special cases where for example devDependencies is for local development, but during deployment you need a slightly different set of dependencies. For example, the following package.json is for a hypothetical deployment to Vercel:

{
  "dependencies": {...},
  "devDependencies": {...},
  "vercelDependencies": {...},
}

and the deployment would be configured to run npm clean-install --include vercel and to run something specific like npm run build:vercel specifically for that case.

This would avoid installing unnecessary dependencies in different scenarios.
