What is MIME type "text/livescript"?

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

The MIME type text/livescript designates files that contain LiveScript code. It tells the system to treat the file’s content as a text script written in LiveScript, which is an early sibling to JavaScript.

LiveScript was once used for adding interactivity to web pages. Now mainstream web scripting mostly uses JavaScript, but text/livescript still marks files meant to be interpreted or compiled from LiveScript.

Main Use Case: Signaling that the file contains LiveScript commands.
It helps web servers negotiate content types and direct browsers to the correct interpreter.
Developers used it to embed dynamic elements in websites before JavaScript became ubiquitous.

Files with this MIME type typically have the extension LS.

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.
