Add post install for bower install in new packages

[jwebbdev]

Should we add a block for

  "scripts": {
    "postinstall" : "bower install"
  },

It seems a lot of people don't realize they need to add this once adding bower dependencies to cause bower installs to cascade along with npm.

It would add a little time to general npm installs based on how many packages you have, but I doubt it would be much, and if it's a concern someone can always remove the post install scripts for deployment so life is easier on new devs.

Yes. This is related to linnovate/meanio#65 and I think it should be enabled by default. It will have to be to support a complete mean package abstraction.

This would automatically execute a bower install by default for all packages in your view?

[jwebbdev]

Yeah, as the npm install cascades through the packages it would cause the bower install to cascade along with it.
