What is an appropriate content-type header for JavaScript files

Question

I am delivering a JS response from a PHP file. When setting the Content-Type header which value should I use, application/javascript or text/javascript?

Answer 1

Hello @kartik,

JS has two registered MIME types:

 The obsolete text/javascript and the now official application/javascript.

Thus, use application/javascript. You can configure your server to always serve application/javascript in the HTTP headers; browsers that don't support it also pay no attention to the actual content-type.

Hope it helps!!

Thank You!!
