## Package.json Loader
## Version Plugin
This loader creates a `version.json` file that gets exposed by the `/__version__` route from the `package.json` file and current git commit hash.
## Version Loader
This loader substitutes the string "VERSION" for the version string specified in `package.json`. This is a workaround because `package.json` already uses the `package_json_loader`. See [app/templates/header/index.js](../app/templates/header/index.js) for more info.
