MIMEType class

Package:

powerbi-client

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.

Constructors

MIMEType(string | { toString: () => string })

Creates a new MIMEType object by parsing the input. A TypeError will be thrown if the input is not a valid MIME. Note that an effort will be made to coerce the given values into strings.

Properties

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

Methods

toString()

The toString() method on the MIMEType object returns the serialized MIME. Because of the need for standard compliance, this method does not allow users to customize the serialization process of the MIME.

Constructor Details

MIMEType(string | { toString: () => string })

Creates a new MIMEType object by parsing the input.

A TypeError will be thrown if the input is not a valid MIME. Note that an effort will be made to coerce the given values into strings.

new MIMEType(input: string | { toString: () => string })

Parameters

input

string | { toString: () => string }

The input MIME to parse.

Property Details

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
