What is MIME type "text/x-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/x-livescript marks files containing code written in the LiveScript language. It helps tools and systems know that the file is a text-based script, ready to be parsed by a LiveScript interpreter.

This MIME type is mainly used in environments where dynamic behavior, similar to that of JavaScript, is needed. It informs browsers, editors, and servers about the file’s content and expected processing. Use cases include:

Enabling interactive web scripting in legacy projects
Supporting syntax highlighting in code editors
Facilitating proper handling by interpreters and development tools

Files with the extensions LS and _LS are typically associated with this MIME type. It functions similarly to other script MIME types but specifically signals that the file’s content is authored in LiveScript. For more details on MIME types, see MDN Web Docs.

Associated file extensions

.ls, ._ls

Usage Examples

HTTP Header

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


    Content-Type: text/x-livescript

HTML

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


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

Server-side (Node.js)

Setting the Content-Type header in Node.js:


    const http = require('http');
    
    http.createServer((req, res) => {
      res.setHeader('Content-Type', 'text/x-livescript');
      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.
