What is MIME type "application/x-clojurescript"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

application/x-clojurescript marks files that hold ClojureScript code. ClojureScript is a variant of Clojure that compiles into JavaScript. This lets developers write code that runs in web browsers or on servers.

Files with this MIME type use the CLJS extension. The identifier helps operating systems, servers, and editors treat them properly.

• Main use case: To signal that a file contains source code meant for compiling into JavaScript.
• Other uses: To enable syntax highlighting, debugging, and build automation in development tools.
• Key fact: The x- prefix indicates this MIME type is experimental or not fully standardized.
