This is the code for https://deno.land/
We want to provide pretty and semantic URLs for modules that will be used within Deno. For example: https://deno.land/std/http/server.ts
When we request this file inside of Deno, we need to receive back the raw content of the file. However, when we visit that URL in the browser we want to see a pretty HTML file with syntax highlighting.
To accomplish this, we look at the "Accept:" HTTP header to see if the client wants HTML or not. If it does want HTML, we simply render the html, else we proxy the file contents from S3 buckets.
For questions or problems regarding modules, please e-mail modules@deno.com.
