Which MIME types are related to file extension ".cljc"?
The .cljc file extension is associated with 1 MIME types:
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .cljc Files
CLJC files are Clojure source code files that work in both the JVM and JavaScript environments.
They are plain text files that follow a Lisp-like syntax. The MIME type is text/x-clojure, which tells editors to use Clojure syntax rules.
They are used for writing cross-platform code. This means the same code can run in both Clojure (server-side) and ClojureScript (client-side) settings.
- Main use: Sharing code between different runtime environments.
- Other uses: Developing libraries, web applications, and tools that need to support both platforms.
According to FilExt.com, CLJC files promote code reuse and easier maintenance in projects where conditional logic enables different behaviors for each platform.
They support using platform-specific conditions (often via reader macros) to write code that adapts to its execution context.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is a .cljc file used for?
A .cljc file contains Clojure source code designed to be portable across different platforms. It allows developers to write logic once and share it between a server-side Clojure application (running on the JVM) and a client-side ClojureScript application (running in a browser). These files often use reader conditionals to handle platform-specific differences.
How do I open and edit a .cljc file?
Since .cljc files are plain text, you can view them in generic editors like Notepad, but dedicated IDEs provide better syntax highlighting. Popular choices include Visual Studio Code (using the Calva extension), IntelliJ IDEA (with the Cursive plugin), and Emacs. These tools recognize the syntax and help manage the cross-platform logic.
What is the difference between .clj, .cljs, and .cljc?
The extension .clj is for standard Clojure code (JVM), while .cljs is specifically for ClojureScript (JavaScript environments). The .cljc extension stands for Clojure Common, meaning the code inside is intended to be compatible with both environments simultaneously.
What is the MIME type for .cljc files?
The standard MIME type for .cljc files is text/x-clojure. This indicates to web servers and editors that the content is a text-based script following Clojure syntax rules. You can verify MIME type configurations at mime-type.com.
How do I run a .cljc file?
You generally do not "run" a .cljc file directly like an executable; it must be compiled or interpreted by a build tool. Tools like Leiningen or Shadow-CLJS compile the code into Java bytecode or JavaScript, depending on the target environment defined in your project settings.
Can I convert a .cljc file to JavaScript?
Yes, but it is usually done automatically during the build process rather than manually. When a ClojureScript compiler processes a .cljc file, it transpiles the code into efficient JavaScript that can run in web browsers or Node.js.
Why does my editor not recognize the .cljc extension?
If your editor treats the file as plain text without colors, you likely need to install a language plugin. If you already have a plugin, ensure the .cljc extension is associated with the text/x-clojure content type in your editor's file association settings.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
