About MIME types
A MIME type, or media type, names the format of a file or message body, such as text/html, application/json or image/png. Servers send it in the Content-Type header so browsers know how to handle a response, and clients send it with request bodies so APIs know how to parse them. It has a type and a subtype, optionally with a suffix (+json, +xml) and parameters such as charset=utf-8.
The official list is the IANA Media Types registry. Names starting with x- and a few common names such as application/rss+xml were never registered but are widely used; they're marked as such below. When a server doesn't know a file's type it should send application/octet-stream, which makes browsers download the file rather than display it. Send X-Content-Type-Options: nosniff so browsers trust the type you declare instead of guessing.

Good to know
Text types and charset
For text formats add the character encoding: Content-Type: text/html; charset=utf-8. JSON is always UTF-8 (RFC 8259), so application/json needs no charset parameter.
JavaScript
RFC 9239 (2022) made text/javascript the one standard type for JavaScript and marked application/javascript and others obsolete. Browsers accept either for scripts, but module scripts are rejected if served with a non-JavaScript type.
