VueJS CKeditor5 upload images - vue.js

Question

Having trouble with uploading images using CKeditor5 in Vuejs.
First having tried Simple upload Adapter which gave me the following error:
Reason: CKEditorError: ckeditor-duplicated-modules: Some CKEditor 5 modules are duplicated. Read more: https://ckeditor.com/docs/ckeditor5/latest/framework/guides/support/error-codes.html#error-ckeditor-duplicated-modules
I tried making a upload adapter. As a uploadadapter I took the example and modified the url. The uploadadapter.js file looks like the following:
export default class UploadAdapter {
constructor( loader ) {
// The file loader instance to use during the upload.
this.loader = loader;
}
// Starts the upload process.
upload() {
return this.loader.file
.then( file => new Promise( ( resolve, reject ) => {
this._initRequest();
this._initListeners( resolve, reject, file );
this._sendRequest( file );
} ) );
}
// Aborts the upload process.
abort() {
if ( this.xhr ) {
this.xhr.abort();
}
}
// Initializes the XMLHttpRequest object using the URL passed to the constructor.
_initRequest() {
const xhr = this.xhr = new XMLHttpRequest();
xhr.open( 'POST', '<url here>', true );
xhr.responseType = 'json';
}
// Initializes XMLHttpRequest listeners.
_initListeners( resolve, reject, file ) {
const xhr = this.xhr;
const loader = this.loader;
const genericErrorText = `Couldn't upload file: ${ file.name }.`;
xhr.addEventListener( 'error', () => reject( genericErrorText ) );
xhr.addEventListener( 'abort', () => reject() );
xhr.addEventListener( 'load', () => {
const response = xhr.response;
if ( !response || response.error ) {
return reject( response && response.error ? response.error.message : genericErrorText );
}
resolve( {
default: response.url
} );
} );
if ( xhr.upload ) {
xhr.upload.addEventListener( 'progress', evt => {
if ( evt.lengthComputable ) {
loader.uploadTotal = evt.total;
loader.uploaded = evt.loaded;
}
} );
}
}
// Prepares the data and sends the request.
_sendRequest( file ) {
// Prepare the form data.
const data = new FormData();
data.append( 'upload', file );
// Send the request.
this.xhr.send( data );
}
}
The Vue component:
<template>
<form #submit.prevent="store">
<ckeditor
:editor="editor"
v-model="form.content"
:error-messages="errors.content"
:config="editorConfig"
/>
</form>
</template>
<script>
import CKEditor from '#ckeditor/ckeditor5-vue';
import ClassicEditor from '#ckeditor/ckeditor5-build-classic';
import UploadAdapter from '../../UploadAdapter';
export default {
data()
{
return {
form: {
content: null,
},
editor: ClassicEditor,
editorConfig: {
toolbar: [ 'heading', '|', 'bold', 'italic', 'link', 'bulletedList', 'numberedList', '|', 'insertTable', '|', 'imageUpload', 'mediaEmbed', '|', 'undo', 'redo' ],
table: {
toolbar: [ 'tableColumn', 'tableRow', 'mergeTableCells' ]
},
extraPlugin: [this.uploader],
language: 'nl',
},
}
},
methods: {
store()
{
// Some code
},
uploader(editor)
{
editor.plugins.get( 'FileRepository' ).createUploadAdapter = ( loader ) => {
return new UploadAdapter( loader );
};
},
},
components: {
ckeditor: CKEditor.component
}
}
</script>
However each time when trying to upload a file the following warning is returned:
filerepository-no-upload-adapter: Upload adapter is not defined. Read more: https://ckeditor.com/docs/ckeditor5/latest/framework/guides/support/error-codes.html#error-filerepository-no-upload-adapter
Have looked at the url but it just sends me in circles thus making no progress. What I'm looking for is an example that at least sends a file to the server without errors/ warnings. If the uploadadapter can be scraped and something else except CKfinder can be used that's fine. For now I guess the problem is most likely to be in the Vue component.

Answer 1

use extraPlugins instead of extraPlugin.

Answer 2

moving uploader function to outside of vue component and then using it directly as
extraPlugin: [uploader]
worked for me.
