FileRepository (upload)

@ckeditor/ckeditor5-upload/src/filerepository

class

File repository plugin. A central point for managing file upload.

To use it, first you need an upload adapter. Upload adapter's job is to handle communication with the server (sending the file and handling server's response). You can use one of the existing plugins introducing upload adapters (e.g. CloudServicesUploadAdapter or CKFinderUploadAdapter) or write your own one – see the Custom image upload adapter deep-dive guide.

Then, you can use createLoader() and the returned FileLoader instance to load and upload files.

Properties

createUploadAdapter : ( FileLoader ) => UploadAdapter | undefined

See source
A factory function which should be defined before using FileRepository.

It should return a new instance of UploadAdapter that will be used to upload files. FileLoader instance associated with the adapter will be passed to that function.

For more information and example see UploadAdapter.
readonly inherited
editor : Editor
See source
The editor instance.

Note that most editors implement the ui property. However, editors with an external UI (i.e. Bootstrap-based) or a headless editor may not have this property or throw an error when accessing it.

Because of above, to make plugins more universal, it is recommended to split features into:
- The "editing" part that uses the Editor class without ui property.
- The "UI" part that uses the Editor class and accesses ui property.
inherited observable
isEnabled : boolean
See source
Flag indicating whether a plugin is enabled or disabled. A disabled plugin will not transform text.

Plugin can be simply disabled like that:
```
// Disable the plugin so that no toolbars are visible.
editor.plugins.get( 'TextTransformation' ).isEnabled = false;
```
You can also use forceDisabled method.
loaders : Collection<FileLoader>

See source
Collection of loaders associated with this repository.
observable
uploadTotal : null | number

See source
Number of total bytes to upload.

It might be different than the file size because of headers and additional data. It contains null if value is not available yet, so it's better to use uploadedPercent to monitor the progress.
observable
uploaded : number

See source
Number of bytes uploaded.
observable
uploadedPercent : number

See source
Upload progress in percents.
private
_loadersMap : Map<File | Promise<File>, FileLoader>

See source
Loaders mappings used to retrieve loaders references.
private
_pendingAction : null | PendingAction

See source
Reference to a pending action registered in a PendingActions plugin while upload is in progress. When there is no upload then value is null.

bind( bindProperties ) → MultiBindChain
See source
Binds observable properties to other objects implementing the Observable interface.

Read more in the dedicated guide covering the topic of property bindings with some additional examples.

Consider two objects: a button and an associated command (both Observable).

A simple property binding could be as follows:
```
button.bind( 'isEnabled' ).to( command, 'isEnabled' );
```
or even shorter:
```
button.bind( 'isEnabled' ).to( command );
```
which works in the following way:
- button.isEnabled instantly equals command.isEnabled,
- whenever command.isEnabled changes, button.isEnabled will immediately reflect its value.
Note: To release the binding, use unbind.

You can also "rename" the property in the binding by specifying the new name in the to() chain:
```
button.bind( 'isEnabled' ).to( command, 'isWorking' );
```
It is possible to bind more than one property at a time to shorten the code:
```
button.bind( 'isEnabled', 'value' ).to( command );
```
which corresponds to:
```
button.bind( 'isEnabled' ).to( command );
button.bind( 'value' ).to( command );
```
The binding can include more than one observable, combining multiple data sources in a custom callback:
```
button.bind( 'isEnabled' ).to( command, 'isEnabled', ui, 'isVisible',
	( isCommandEnabled, isUIVisible ) => isCommandEnabled && isUIVisible );
```
Using a custom callback allows processing the value before passing it to the target property:
```
button.bind( 'isEnabled' ).to( command, 'value', value => value === 'heading1' );
```
It is also possible to bind to the same property in an array of observables. To bind a button to multiple commands (also Observables) so that each and every one of them must be enabled for the button to become enabled, use the following code:
```
button.bind( 'isEnabled' ).toMany( [ commandA, commandB, commandC ], 'isEnabled',
	( isAEnabled, isBEnabled, isCEnabled ) => isAEnabled && isBEnabled && isCEnabled );
```
Parameters

bindProperties : Array<'off' | 'on' | 'once' | 'listenTo' | 'stopListening' | 'fire' | 'delegate' | 'stopDelegating' | 'set' | 'bind' | 'unbind' | 'decorate' | 'destroy' | 'isEnabled' | 'init' | 'editor' | 'forceDisabled' | 'clearForceDisabled' | 'loaders' | 'createUploadAdapter' | 'uploaded' | 'uploadTotal' | 'uploadedPercent' | 'getLoader' | 'createLoader' | 'destroyLoader'>

inherited
clearForceDisabled( id ) → void

See source
Clears forced disable previously set through forceDisabled. See forceDisabled.

Parameters

id : string

Unique identifier, equal to the one passed in forceDisabled call.

Returns

void
createLoader( fileOrPromise ) → null | FileLoader

See source
Creates a loader instance for the given file.

Requires createUploadAdapter factory to be defined.

Parameters

fileOrPromise : File | Promise<File>

Native File object or native Promise object which resolves to a File.

Returns

null | FileLoader
inherited
decorate( methodName ) → void
See source
Turns the given methods of this object into event-based ones. This means that the new method will fire an event (named after the method) and the original action will be plugged as a listener to that event.

Read more in the dedicated guide covering the topic of decorating methods with some additional examples.

Decorating the method does not change its behavior (it only adds an event), but it allows to modify it later on by listening to the method's event.

For example, to cancel the method execution the event can be stopped:
```
class Foo extends ObservableMixin() {
	constructor() {
		super();
		this.decorate( 'method' );
	}

	method() {
		console.log( 'called!' );
	}
}

const foo = new Foo();
foo.on( 'method', ( evt ) => {
	evt.stop();
}, { priority: 'high' } );

foo.method(); // Nothing is logged.
```
Note: The high priority listener has been used to execute this particular callback before the one which calls the original method (which uses the "normal" priority).

It is also possible to change the returned value:
```
foo.on( 'method', ( evt ) => {
	evt.return = 'Foo!';
} );

foo.method(); // -> 'Foo'
```
Finally, it is possible to access and modify the arguments the method is called with:
```
method( a, b ) {
	console.log( `${ a }, ${ b }`  );
}

// ...

foo.on( 'method', ( evt, args ) => {
	args[ 0 ] = 3;

	console.log( args[ 1 ] ); // -> 2
}, { priority: 'high' } );

foo.method( 1, 2 ); // -> '3, 2'
```
Parameters

methodName : 'off' | 'on' | 'once' | 'listenTo' | 'stopListening' | 'fire' | 'delegate' | 'stopDelegating' | 'set' | 'bind' | 'unbind' | 'decorate' | 'destroy' | 'isEnabled' | 'init' | 'editor' | 'forceDisabled' | 'clearForceDisabled' | 'loaders' | 'createUploadAdapter' | 'uploaded' | 'uploadTotal' | 'uploadedPercent' | 'getLoader' | 'createLoader' | 'destroyLoader'

Name of the method to decorate.

Returns

void
inherited
delegate( events ) → EmitterMixinDelegateChain
See source
Delegates selected events to another Emitter. For instance:
```
emitterA.delegate( 'eventX' ).to( emitterB );
emitterA.delegate( 'eventX', 'eventY' ).to( emitterC );
```
then eventX is delegated (fired by) emitterB and emitterC along with data:
```
emitterA.fire( 'eventX', data );
```
and eventY is delegated (fired by) emitterC along with data:
```
emitterA.fire( 'eventY', data );
```
Parameters

events : Array<string>

Event names that will be delegated to another emitter.

Returns

EmitterMixinDelegateChain
inherited
destroy() → void

See source
Destroys the plugin.

Note: This method is optional. A plugin instance does not need to have it defined.

Returns

void
destroyLoader( fileOrPromiseOrLoader ) → void

See source
Destroys the given loader.

Parameters

fileOrPromiseOrLoader : File | FileLoader | Promise<File>

File or Promise associated with that loader or loader itself.

Returns

void
inherited
fire( eventOrInfo, args ) → GetEventInfo<TEvent>[ 'return' ]

See source
Fires an event, executing all callbacks registered for it.

The first parameter passed to callbacks is an EventInfo object, followed by the optional args provided in the fire() method call.

Type parameters

TEvent : extends BaseEvent

The type describing the event. See BaseEvent.

Parameters

eventOrInfo : GetNameOrEventInfo<TEvent>

The name of the event or EventInfo object if event is delegated.

args : TEvent[ 'args' ]

Additional arguments to be passed to the callbacks.

Returns

GetEventInfo<TEvent>[ 'return' ]

By default the method returns undefined. However, the return value can be changed by listeners through modification of the evt.return's property (the event info is the first param of every callback).
inherited
forceDisabled( id ) → void
See source
Disables the plugin.

Plugin may be disabled by multiple features or algorithms (at once). When disabling a plugin, unique id should be passed (e.g. feature name). The same identifier should be used when enabling back the plugin. The plugin becomes enabled only after all features enabled it back.

Disabling and enabling a plugin:
```
plugin.isEnabled; // -> true
plugin.forceDisabled( 'MyFeature' );
plugin.isEnabled; // -> false
plugin.clearForceDisabled( 'MyFeature' );
plugin.isEnabled; // -> true
```
Plugin disabled by multiple features:
```
plugin.forceDisabled( 'MyFeature' );
plugin.forceDisabled( 'OtherFeature' );
plugin.clearForceDisabled( 'MyFeature' );
plugin.isEnabled; // -> false
plugin.clearForceDisabled( 'OtherFeature' );
plugin.isEnabled; // -> true
```
Multiple disabling with the same identifier is redundant:
```
plugin.forceDisabled( 'MyFeature' );
plugin.forceDisabled( 'MyFeature' );
plugin.clearForceDisabled( 'MyFeature' );
plugin.isEnabled; // -> true
```
Note: some plugins or algorithms may have more complex logic when it comes to enabling or disabling certain plugins, so the plugin might be still disabled after clearForceDisabled was used.

Parameters

id : string

Unique identifier for disabling. Use the same id when enabling back the plugin.

Returns

void
getLoader( fileOrPromise ) → null | FileLoader

See source
Returns the loader associated with specified file or promise.

To get loader by id use fileRepository.loaders.get( id ).

Parameters

fileOrPromise : File | Promise<File>

Native file or promise handle.

Returns

null | FileLoader
init() → void

See source

Returns

void
inherited
listenTo( emitter, event, callback, [ options ] ) → void
See source
Registers a callback function to be executed when an event is fired in a specific (emitter) object.

Events can be grouped in namespaces using :. When namespaced event is fired, it additionally fires all callbacks for that namespace.
```
// myEmitter.on( ... ) is a shorthand for myEmitter.listenTo( myEmitter, ... ).
myEmitter.on( 'myGroup', genericCallback );
myEmitter.on( 'myGroup:myEvent', specificCallback );

// genericCallback is fired.
myEmitter.fire( 'myGroup' );
// both genericCallback and specificCallback are fired.
myEmitter.fire( 'myGroup:myEvent' );
// genericCallback is fired even though there are no callbacks for "foo".
myEmitter.fire( 'myGroup:foo' );
```
An event callback can stop the event and set the return value of the fire method.

Type parameters

TEvent : extends BaseEvent

The type describing the event. See BaseEvent.

Parameters

emitter : Emitter

The object that fires the event.

event : TEvent[ 'name' ]

The name of the event.

callback : GetCallback<TEvent>

The function to be called on event.

[ options ] : GetCallbackOptions<TEvent>

Additional options.

Returns

void
inherited
off( event, callback ) → void

See source
Stops executing the callback on the given event. Shorthand for this.stopListening( this, event, callback ).

Parameters

event : string

The name of the event.

callback : Function

The function to stop being called.

Returns

void
inherited
on( event, callback, [ options ] ) → void

See source
Registers a callback function to be executed when an event is fired.

Shorthand for this.listenTo( this, event, callback, options ) (it makes the emitter listen on itself).

Type parameters

TEvent : extends BaseEvent

The type descibing the event. See BaseEvent.

Parameters

event : TEvent[ 'name' ]

The name of the event.

callback : GetCallback<TEvent>

The function to be called on event.

[ options ] : GetCallbackOptions<TEvent>

Additional options.

Returns

void
inherited
once( event, callback, [ options ] ) → void

See source
Registers a callback function to be executed on the next time the event is fired only. This is similar to calling on followed by off in the callback.

Type parameters

TEvent : extends BaseEvent

The type descibing the event. See BaseEvent.

Parameters

event : TEvent[ 'name' ]

The name of the event.

callback : GetCallback<TEvent>

The function to be called on event.

[ options ] : GetCallbackOptions<TEvent>

Additional options.

Returns

void
inherited
set( values ) → void
See source
Creates and sets the value of an observable properties of this object. Such a property becomes a part of the state and is observable.

It accepts a single object literal containing key/value pairs with properties to be set.

This method throws the observable-set-cannot-override error if the observable instance already has a property with the given property name. This prevents from mistakenly overriding existing properties and methods, but means that foo.set( 'bar', 1 ) may be slightly slower than foo.bar = 1.

In TypeScript, those properties should be declared in class using declare keyword. In example:
```
public declare myProp1: number;
public declare myProp2: string;

constructor() {
	this.set( {
		'myProp1: 2,
		'myProp2: 'foo'
	} );
}
```
Parameters

values : object

An object with name=>value pairs.

Returns

void
inherited
set( name, value ) → void
