I need to know what could be the correct current/future proof Javascript MIME type.

References

RFC 4329- April 2006, seems to say text/javascript is obsolete and recommends to use application/javascript :

Use of the "text" top-level type for this kind of content is known to be problematic. This document thus defines text/javascript and text/ecmascript but marks them as "obsolete".

HTML Living Standard — Updated 2 July 2019 I guess says text/javascript is fine :

The term "JavaScript" is used to refer to ECMA-262, rather than the official term ECMAScript, since the term JavaScript is more widely known. Similarly, the MIME type used to refer to JavaScript in this specification is text/javascript, since that is the most commonly used type, despite it being an officially obsoleted type according to RFC 4329. [RFC4329]

So at this point text/javascript is correct?

Internet Draft - ECMAScript Media Types Updates to RFC4329, which is said to expire on December 21, 2019, says

This document updates the existing media types for the ECMAScript programming language. It supersedes the media types registrations in [RFC4329] for "application/javascript" and "text/javascript".

application/javascript - Intended usage: OBSOLETE

The first version of the same draft on October 7, 2017, also says

text/javascript has been moved intended usage from OBSOLETE to COMMON.

Also MDN - Incomplete list of MIME types mention JavaScript MIME type ad text/javascript

Question

Part 1. What would be the correct MIME type at present/after December 21, 2019, if the draft expires/does not expire?

Part 2. Should the drafts be followed before they are finalized?

PS :

This is NOT a duplicate of the following questions. I have gone through most of the main discussions in these questions.

  1. text/javascript vs application/javascript ~ 5+ years old.
  2. When to use the JavaScript MIME type application/javascript instead of text/javascript? ~ 8+ years old.
  3. When serving JavaScript files, is it better to use the application/javascript or application/x-javascript - 10+ years old
  4. What is the javascript MIME type for the type attribute of a script tag? ~ 10+ years old.

    "This is NOT a duplicate of the following questions" — Yes, it is. You want to know what to use in the type attribute, and the spec says to omit it entirely, which is what the duplicate says.

    The question in your title is not the question in your text. The title asks what the correct MIME type is. The text asks what to put in the script element. As Quentin says, the correct thing for the script element is to leave type off entirely when the content is JavaScript.

    The question of what the correct MIME type is remains interesting. I'm fairly sure it's text/javascript now, and RFC 4329's vague "known to be problematic" is (13 years later) obsolete. But in pragmatic terms: text/javascript and application/javascript will be treated the same way by any reasonable consumer of MIME types.

    Re edit: It doesn't matter because it is such a mess now that everything is going to be compatible with everything forever. (That's an opinion. I don't think an answer to that could be anything but an opinion).

  • Ok. So you are of the opinion that it might not make much difference even if the draft update proposal to RFC4329 expires (without being replaced by an updated version)?
