Uniform Type Identifier

Please see ars technica article for a description about the principles of UTIs.

For a list of known UTIs please see here

example

myuti.js

1import { UTIController } from "uti";
2
3const uc = new UTIController();
4const doesConformTo = uc.conformsTo("public.image", "public.data");
5console.log("doesConformTo: " + doesConformTo);
6
7console.log(uc.getUTIsForFileName("a.txt")[0]);

Output

1doesConformTo: true
2public.plain-text

API

UTI
- Parameters
- Properties
- name
- conforms
- conformsTo
  - Parameters
- toString
- toJSON
UTIController

UTI

Object representing a UTI.

Parameters

name string
conforms Set<UTI>

Properties

name string
conforms Set<UTI>

name

Type: string

conforms

Type: Set<UTI>

conformsTo

Check for conformity.

Parameters

other (UTI | undefined)

Returns boolean true if other conforms to the receiver

toString

name of the UTI.

Returns string

toJSON

Deliver JSON representation of the UTI. Sample result

1{
2  "name": "myUTI",
3  "conformsTo": [ "uti1", "uti2"]
4}

Returns {name: string, conforms: Array<string>} json representation of the UTI

UTIController

Registry of UTIs.

Properties

registry Map<string, UTI>
utiByMimeType Map<string, UTI>
utiByFileNameExtension Map<string, UTI>

register

Registers additional types.

Parameters

types Array<UTI>

getUTI

Lookup a given UTI.

Parameters

name string UTI

Returns (UTI | undefined) UTI for the given name or undefined if UTI is not present.

getUTIsForMimeType

Lookup a UTIs for a mime type.

Parameters

mimeType string mime type to get UTIs for

Returns Array<string> UTIs for the given mime type

getUTIsForFileName

Lookup a UTI for a file name. First the file name extension is extracted. Then a lookup in the registered UTIs for file name extension is executed.

Parameters

fileName string file to detect UTI for

Returns Array<string> UTIs for the given fileName

conformsTo

Check whenever two UTI are conformant. If a conforms to b and b conforms to c then a also conforms to c.

Parameters

a string first UTI
b string second UTI

Returns boolean true if UTI a conforms to UTI b.

fileNameConformsTo

Lookup a UTI for a file name and check conformance.

Parameters

fileName string file to detect UTI for
uti string to check conformance against

Returns boolean true if utils for file name are conformant

assignMimeTypes

Assign mime types to a UTI

Parameters

uti string
mimeTypes Array<string>

assignExtensions

Assign mime types to a UTI

Parameters

uti string
extensions Array<string>
