A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .cljx Files
CLJX files are plain text files containing source code written in the Clojure language.
They use the MIME type text/x-clojure to signal that the content is code formatted for Clojure’s syntax.
These files were originally designed to support code sharing between different Clojure environments—often between the JVM and JavaScript platforms—by using preprocessor-style annotations.
They work similarly to CLJC files, allowing developers to write cross-compatible code that can be transformed for various targets.
You can edit and view them with many text editors and IDEs, such as IntelliJ IDEA (with the Cursive plugin), Visual Studio Code, or Emacs.
- Useful for cross-platform code reuse in the Clojure ecosystem
- Plain text format that is simple to read and edit
- Often processed by compilers or preprocessor tools to generate environment-specific code
- MIME type text/x-clojure clearly identifies its nature as source code
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 .cljx file used for?
A .cljx file contains portable Clojure source code designed to be shared between different platforms, such as the Java Virtual Machine (Clojure) and JavaScript engines (ClojureScript). It allows developers to write logic once and target multiple environments using preprocessor annotations.
How do I open and edit a .cljx file?
Since .cljx files are plain text, you can open them with any code editor, including Visual Studio Code, Sublime Text, or Emacs. For the best experience, use an IDE like IntelliJ IDEA with the Cursive plugin, which provides syntax highlighting for Clojure code.
What is the difference between .cljx and .cljc files?
.cljx is an older format that requires a separate build step to generate platform-specific code, whereas .cljc uses "reader conditionals" supported natively by modern Clojure compilers. Most new projects prefer .cljc for simpler cross-platform development.
How do I run or compile a .cljx file?
You generally do not run a .cljx file directly; instead, it is processed by a build tool like Leiningen (using the cljx plugin) or Boot. This process transforms the file into standard .clj or .cljs files, which are then compiled and executed.
What is the correct MIME type for .cljx files?
These files are typically served with the MIME type text/x-clojure, which identifies them as Clojure source code. You can verify specific MIME configurations at mime-type.com.
Are .cljx files safe to open?
Yes, .cljx files are simple text files and are safe to view in any text editor. However, you should exercise caution before executing the code they contain or running build scripts from untrusted sources.
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.
