Banner

Banner creates headers automatically, by parsing package.json, the npm standard for versioning nodejs packages. It also uses git describe to add a git tag & revision.

It's used in Wax to eliminate one of the headaches of distributed-client-library development.

Include it in your devDependencies, like

"devDependencies": {
  "banner": "0.0.x"
}

Then use it in a makefile, like

BANNER = ./node_modules/.bin/banner

dist_setup:
    mkdir dist
    $(BANNER) package.json > dist/header.js

And then you'll have less of a headache figuring out what version of a client-side library you, or someone else, is using, since every file has a concise comment describing the specific version and, if it's a development build beyond a certain tag, the exact git tree it was built from.

Minification tools like uglifyjs maintain the first comment in a file, so even minified versions will retain this versioning information.
