php – What is an appropriate content-type header for JavaScript files?

Posted by: admin April 23, 2020 Leave a comment

Questions:

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?

What’s the difference between the two?

How to&Answers:

According to the IANA Registered MIME media type list, JS has two registered MIME types; the obsolete text/javascript and the now official application/javascript.

Thus, use application/javascript.

Answer:

From Wikipedia on Internet Media Types

application/javascript: JavaScript; Defined in RFC 4329 but not accepted in IE 8 or earlier

There is also the deprecated text/javascript (which IE will probably not choke on).
