Develop Reference

I want to integrate Medium's.com text editor in my Django Blog where users can write articles thoroughly?

First of all use medium's editor thoroughly if you didn't before, I want as it is that of Editor, if user want to upload image then editor save image, video etc on its own server then provide us images videos link by img tag..

I've done this previously using TinyMCE. You need to add tinymce js link in you base html and initialize tinymce in template where user will be writing post. An example of template you can see.
This is how the post looks.

CKEditor 5 and Image Button

I'm trying to figure out how to upload images with CK Editor 5. Now I've seen a whole size of different plugins, but I would like to learn how this works for myself. What I have noticed is that if I click the image button, I get a dialog to upload the image and then I select an image and nothing happens.
Based on the guides and articles I have been reading, my assumption is that I have to save the image to the server and then give the url back to the ckeditor so that it may use it to display the image.
What I can't seem to figure out is how to do that. Where in the ckeditor js code would I add my own logic so that it may pick up the uploaded image, send it to the server and then give a url back to ck editor?
I've been through a lot of documentation such as this, but I can't seem to find anything.
https://docs.ckeditor.com/ckeditor5/latest/features/image.html
https://docs.ckeditor.com/ckeditor5/latest/features/image-upload.html

Did you check the console? On the console, if you don't have the editor properly configured, you'd have something like this:
filerepository-no-upload-adapter: Upload adapter is not defined. Read more: https://docs.ckeditor.com/ckeditor5/latest/framework/guides/support/error-codes.html#error-filerepository-no-upload-adapter
Now, there are two built-in upload adapters – for CKFinder's server connector and for the Easy Image service provided by CKEditor Cloud Services. Both need to be configured to work:
CKFinder adapter: https://docs.ckeditor.com/ckeditor5/latest/api/module_adapter-ckfinder_uploadadapter-CKFinderAdapterConfig.html
Easy Image: https://docs.ckeditor.com/ckeditor5/latest/features/image-upload.html#easy-image
The role of an upload adapter is to expose a function which will send a file to the server (in whatever way it wants) and notify the editor once the upload is done (by returning a URL to this file). The editor takes care of the rest – inserting the image into the content, displaying a progress bar, etc.
Besides using the built-in adapters, you can write your own one. See:
https://docs.ckeditor.com/ckeditor5/latest/api/module_upload_filerepository-Adapter.html
https://github.com/ckeditor/ckeditor5-adapter-ckfinder/tree/master/src as an example of a simple upload adapter

Alloy Editor : upload multiple images on my server from content

Is it possible to upload the multiple images from pasted content of google drive document or local documents i.e articles ?
After pasting the content from document, i want to upload all images on my server
Currently, when i drop/select image (single) in editor area locally then using "imageAdd" event i can upload the image to my server, but same thing when i do by selecting the image (having google image url) from document that time its not working.
want to implement : all images which i have copied in editor which are hosted in different server, need to upload on my server

You need a plugin that detects whenever content is copied into the editor, then find out any external image and then imports them into your server.
This is an example of such plugin https://www.pluginsforckeditor.com/imagesfromserver/ although you can write your own.

Generating image preview of a doc or pdf file

Hey guys I have searched a lot but didnt get any working solution for this problem.
I am working on a site using jsp and on this we have to upload forms in doc / docx/ pdf format. I want to generate the preview of the first page of the form. So that user can checkout whats in the form before downloading it.
Hope someone will come up with some solution for this.
Thanks

Not sure what OS platform you are on for your jsp, but my recommendation would be to have a virtual printer driver that can "print" the document at hand to an image file (or as HTML). Then you can manipulate the output of the printer driver anyway you want. Extends itself nicely to other file formats as well.
Another version of this technique would be to programatically open the document with Microsoft Word (using ole automation), then do a screen capture after the document opens. Word can load PDF files as well. You'll have to find a creative way to get the document into a Windows desktop process from your server. But it could work.

Well.. what you can do is..
Hyperlink the form names with relative paths of your jsp with download option. You need to write a servlet to download the form.. preview this jsp in pop up window.
or
use iframes in html create a div tag to preview and download the same form you are displaying. You need to write a servlet to download the form.
Make sure you set the appropriate contentType of your forms doc/pdf/jsp using response.contentType("image/jpg");
response.contentType("application/pdf");
response.contentType("application/doc");

Javascript wysiwyg editor with image upload functionality (use with JEditable)

I'm looking for a good wysiwyg editor with image upload functionality (i.e. a user can add as many pictures as he likes, form URL's or disk, and they'll be uploaded).
I already tried TinyMCE, but it was really heavy and took a very long time to load (I'm using JEditable to only make the editor appear when the user clicks on it).

I've used the components from dhtmlx.com and had pretty good success with them. You can buy the libraries or use the open source version of them if your project qualifies.
You can find the editor library here: http://dhtmlx.com/docs/products/dhtmlxEditor/index.shtml
