What is MIME type "application/x-object"?

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

The MIME type application/x-object labels files that hold compiled code. They are object files produced by a compiler that contain machine instructions, relocation data, and symbols. These files are intermediate outputs and need to be linked to form a complete executable.

They are used in software builds where compiled modules are combined during the linking process. Developers rely on these files to optimize incremental builds and debug subtle issues. Common file extensions include OBJ and O.

• They contain binary code segments ready for the linker.
• They hold relocation information needed for addressing during the final build.
• They help speed up recompilation by enabling modular builds.
• They assist in isolating and debugging specific code sections.

The x- prefix indicates that this MIME type is experimental or non-standard. For more details on how object files work, visit Wikipedia’s Object File article.

Server-side (Node.js)

Setting the Content-Type header in Node.js:

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