This is the webserver and database for the https://deno.land/x/ service.
This service allows people to create pretty URLs which redirect to github (or other content). For example:
deno -A https://deno.land/x/std@v0.2.7/http/file_server.ts
To run the dev server (you shouldn’t need to do this to add a package to the registry):
cd src
npm install
npm start
the registry will launch at http://localhost:4000/x/
