What is MIME type "text/coffeescript"?

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

text/coffeescript is a MIME type that signals a file contains CoffeeScript code.
CoffeeScript is a language that compiles to JavaScript, offering a more concise and readable syntax.
When a server sends a file with this MIME type, software tools know to treat it as plain text meant for further processing or compilation.
A typical file using this MIME type is named using the COFFEE extension.
It is practical in development environments where build tools and transpilers automatically convert CoffeeScript into JavaScript.

Development: Used by developers to write and organize source code that will eventually run as JavaScript.
Tooling Integration: Supports syntax highlighting and error checking in code editors.
Build Processes: Facilitates automated compilation in web development workflows.

For a broader context on how MIME types work, refer to the guide on MDN Web Docs.

Usage Examples

HTTP Header

When serving content with this MIME type, set the Content-Type header:

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.
