MIMEType class
An implementation of the MIMEType class.
In accordance with browser conventions, all properties of MIMEType objects
are implemented as getters and setters on the class prototype, rather than as
data properties on the object itself.
A MIME string is a structured string containing multiple meaningful
components. When parsed, a MIMEType object is returned containing
properties for each of these components.

essence
Gets the essence of the MIME. This property is read only.
Use mime.type or mime.subtype to alter the MIME.

const myMIME = new MIMEType('text/javascript;key=value');
console.log(myMIME.essence);
// Prints: text/javascript
myMIME.type = 'application';
console.log(myMIME.essence);
// Prints: application/javascript
console.log(String(myMIME));
// Prints: application/javascript;key=value
essence: string
Property Value
string
params
Gets the MIMEParams object representing the
parameters of the MIME. This property is read-only. See MIMEParams documentation for details.
params: MIMEParams
Property Value
subtype
Gets and sets the subtype portion of the MIME.
import { MIMEType } from 'node:util';
const myMIME = new MIMEType('text/ecmascript');
console.log(myMIME.subtype);

myMIME.subtype = 'javascript';
console.log(myMIME.subtype);
// Prints: javascript
console.log(String(myMIME));
// Prints: text/javascript
subtype: string

myMIME.type = 'application';
console.log(myMIME.type);
// Prints: application
console.log(String(myMIME));
// Prints: application/javascript
type: string
Property Value
