What is MIME type "text/x-coffeescript"?

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

text/x-coffeescript marks source files written in CoffeeScript and its variants. It tells programs that the file is plain text code meant to be processed by CoffeeScript compilers.
CoffeeScript is a language that converts into JavaScript. Its compact syntax makes coding faster and often more readable.
This MIME type guides editors, IDEs, and build tools to apply the correct syntax rules and highlighting, which aids in error detection and code management.

Text format: Indicates that the file contains plain text, not binary data.
Compilation core: Files follow a structure that compiles directly into JavaScript.
Tool integration: Ensures that development environments process the code for better editing and debugging.

It is linked to projects using similar languages and file types. Common files include COFFEE, EM, _COFFEE, CAKE, CJSX, CSON, EMBERSCRIPT, and ICED.
This MIME type is key in projects that modernize JavaScript development with alternative, more concise code.

    Content-Type: text/x-coffeescript

HTML

In HTML, you can specify the MIME type in various elements:


    <a href="file.dat" type="text/x-coffeescript">Download file</a>

Server-side (Node.js)

Setting the Content-Type header in Node.js:

    http.createServer((req, res) => {
      res.setHeader('Content-Type', 'text/x-coffeescript');
      res.end('Content here');
    }).listen(3000);

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 are multiple MIME types listed for one extension?

Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
