React Draft Wysiwyg: Image Upload when I click the "Add" Button

Question

On a React.js Application I try to make the https://jpuri.github.io/react-draft-wysiwyg/#/docs editor to upload an image and embend it into the editor's content.

So Far I managed to do this with this piece of code:

import React, { Component } from 'react';
import { Editor } from 'react-draft-wysiwyg';
import {convertFromRaw, convertToRaw, EditorState} from 'draft-js';    
import "../../node_modules/react-draft-wysiwyg/dist/react-draft-wysiwyg.css"
import "../../node_modules/draft-js-image-plugin/lib/plugin.css"



export default class CustomEditor extends Component {

  uploadCallback(file) {

    return new Promise(
      (resolve, reject) => {
        var reader=new FileReader();

        reader.onloadend = function() {
          Meteor.call('fileStorage.uploadFile',reader.result,file.name,file.type,(err,response)=>{
              console.log(response)
             if(err){
               reject(err)
             }

             resolve({ data: { link: response.data.url } });
          })
        }

        reader.readAsDataURL(file);
      }
    );
  }

  render() {

    const config={
      image: { uploadCallback: this.uploadCallback }
    }

    return (
      <div className="container-fluid">
        <Editor toolbar={ config } />
      </div>
    )
  }
}

But my problem is that the image uploading procces gets initiated when I select the file, what I want to initiate the upload process when I click on "Add" button as you see in the image bellow:

So how I can do that?

Answer 1

It's not possible to change this behaviour.

The only option you can provide is uploadCallback , see the docs .

You can find the source for the upload code here , it's quite clear, it's not possible.

Answer 2

use toolbar props inside editor toolbar={image: { uploadCallback: uploadCallback }} and write a uploadCallback function like this below.

 const uploadCallback = (file, callback) => { console.log(file); return new Promise((resolve, reject) => { const reader = new window.FileReader(); console.log(reader); reader.onloadend = async () => { const form_data = new FormData(); form_data.append("file", file); const res = await uploadFile(form_data); setValue("thumbnail", res.data); resolve({ data: { link: process.env.REACT_APP_API + res.data } }); }; reader.readAsDataURL(file); }); }; const config = { image: { uploadCallback: uploadCallback }, };

 <Editor toolbar={config} editorState={editorState} toolbarClassName="toolbarClassName" wrapperClassName="wrapperClassName" editorClassName="editorClassName" onEditorStateChange={onEditorStateChange} placeholder="Write your comment here" />
