import { contentType } from "https://deno.land/x/fastro@v0.84.23/http/server/deps.ts";
Given an extension or media type, return a full Content-Type or
Content-Disposition header value.
The function will treat the extensionOrType as a media type when it
contains a /, otherwise it will process it as an extension, with or without
the leading ..
Returns undefined if unable to resolve the media type.
Note: a side effect of
deno/x/media_typeswas that you could pass a file name (e.g.file.json) and it would return the content type. This behavior is intentionally not supported here. If you want to get an extension for a file name, useextname()fromstd/path/mod.tsto determine the extension and pass it here.
