vangen

Vangen is a tool for generating static HTML for Go vanity import paths.

Go vanity import paths work by serving a HTML file that tells the go get tool where to download the source from. You can still host the source code at Github, BitBucket, but the vanity URL gives you portability and other benefits.

Why

Maintain Go vanity import paths with a simple definition file vangen.json.
Host Go vanity import paths using static hosting. No need for Google AppEngine, Heroku, etc. Host the files on Github Pages, AWS S3, Google Cloud Storage, etc.

go get 4d63.com/vangen
