e.g. https://js.org/express 301 redirects to https://www.npmjs.com/package/express
Another idea is a blog. One of my favorite blogs is http://npmawesome.com/
- When a project reaches a popularity threshold (for example 10k github stars or gets to be the most popular project is his category - example: the most popular 3D library) would get a subdomain:
https://jquery.js.org/eachplugin
https://node.js.org/express
When we get exceptions, in this case, express grew and got autonomous, https://node.js.org/express would redirect to:
https://express.js.org/
