How do I upload images? #83

TheStarkor · 2021-01-05T06:41:31Z

I have an upload server (https://.../upload/img) that returns an image's URL and I found the commands.image.

I want to modify the commands that can upload an image(how to..?) and return ![](res.url)(I can do it with execute)

Can I add components like the figure?

The text was updated successfully, but these errors were encountered:

@TheStarkor I need to expand this

Do you need such an effect?

TheStarkor · 2021-01-07T02:33:48Z

Yes! That's what I want.

Hello @jaywcjlove the example is not working and we wanted to implement a small drag & drop it

into our markdown

How to implement with a custom component eg: Modal?

dino3616 · 2022-07-15T11:55:01Z

Hi, I have tried to implement a way to upload an image by Drag&Drop directly into the editor or by Copy&Paste and display it in the preview.
It may not be a very pretty method, but I hope it will be useful to you.
Here's my EXAMPLE!

import MDEditor from '@uiw/react-md-editor';
import { useState } from 'react';
import onImagePasted from './utils/onImagePasted';
import '@uiw/react-md-editor/markdown-editor.css';
import '@uiw/react-markdown-preview/markdown.css';

const MdEditor = () => {
  const [markdown, setMarkdown] = useState<string | undefined>();

  return (
    <div data-color-mode="light">
      <MDEditor
        value={markdown}
        onChange={(value) => {
          setMarkdown(value);
        }}
        onPaste={async (event) => {
          await onImagePasted(event.clipboardData, setMarkdown);
        }}
        onDrop={async (event) => {
          await onImagePasted(event.dataTransfer, setMarkdown);
        }}
        height={440}
        textareaProps={{
          placeholder: 'Fill in your markdown for the coolest of the cool.',
        }}
        hideToolbar
      />
    </div>
  );
};

export default MdEditor;

import type { SetStateAction } from 'react';
import { fileUpload } from '../../../../../libs/firebase/storage';
import insertToTextArea from './insertToTextArea';

const onImagePasted = async (dataTransfer: DataTransfer, setMarkdown: (value: SetStateAction<string | undefined>) => void) => {
  const files: File[] = [];
  for (let index = 0; index < dataTransfer.items.length; index += 1) {
    const file = dataTransfer.files.item(index);

    if (file) {
      files.push(file);
    }
  }

  await Promise.all(
    files.map(async (file) => {
      const url = await fileUpload(file);
      const insertedMarkdown = insertToTextArea(`![](${url})`);
      if (!insertedMarkdown) {
        return;
      }
      setMarkdown(insertedMarkdown);
    }),
  );
};

export default onImagePasted;

const insertToTextArea = (intsertString: string) => {
  const textarea = document.querySelector('textarea');
  if (!textarea) {
    return null;
  }

  let sentence = textarea.value;
  const len = sentence.length;
  const pos = textarea.selectionStart;
  const end = textarea.selectionEnd;

  const front = sentence.slice(0, pos);
  const back = sentence.slice(pos, len);

  sentence = front + intsertString + back;

  textarea.value = sentence;
  textarea.selectionEnd = end + intsertString.length;

  return sentence;
};

export default insertToTextArea;

Modify text.

Can I open a component below the button(commands)?

can you share the code that open your component (e.g a modal) ?

Hi, I have tried to implement a way to upload an image by Drag&Drop directly into the editor or by Copy&Paste and display it in the preview. It may not be a very pretty method, but I hope it will be useful to you. Here's my EXAMPLE!

import MDEditor from '@uiw/react-md-editor';
import { useState } from 'react';
import onImagePasted from './utils/onImagePasted';
import '@uiw/react-md-editor/markdown-editor.css';
import '@uiw/react-markdown-preview/markdown.css';

const MdEditor = () => {
  const [markdown, setMarkdown] = useState<string | undefined>();

  return (
    <div data-color-mode="light">
      <MDEditor
        value={markdown}
        onChange={(value) => {
          setMarkdown(value);
        }}
        onPaste={async (event) => {
          await onImagePasted(event.clipboardData, setMarkdown);
        }}
        onDrop={async (event) => {
          await onImagePasted(event.dataTransfer, setMarkdown);
        }}
        height={440}
        textareaProps={{
          placeholder: 'Fill in your markdown for the coolest of the cool.',
        }}
        hideToolbar
      />
    </div>
  );
};

export default MdEditor;

import type { SetStateAction } from 'react';
import { fileUpload } from '../../../../../libs/firebase/storage';
import insertToTextArea from './insertToTextArea';

const onImagePasted = async (dataTransfer: DataTransfer, setMarkdown: (value: SetStateAction<string | undefined>) => void) => {
  const files: File[] = [];
  for (let index = 0; index < dataTransfer.items.length; index += 1) {
    const file = dataTransfer.files.item(index);

    if (file) {
      files.push(file);
    }
  }

  await Promise.all(
    files.map(async (file) => {
      const url = await fileUpload(file);
      const insertedMarkdown = insertToTextArea(`![](${url})`);
      if (!insertedMarkdown) {
        return;
      }
      setMarkdown(insertedMarkdown);
    }),
  );
};

export default onImagePasted;

const insertToTextArea = (intsertString: string) => {
  const textarea = document.querySelector('textarea');
  if (!textarea) {
    return null;
  }

  let sentence = textarea.value;
  const len = sentence.length;
  const pos = textarea.selectionStart;
  const end = textarea.selectionEnd;

  const front = sentence.slice(0, pos);
  const back = sentence.slice(pos, len);

  sentence = front + intsertString + back;

  textarea.value = sentence;
  textarea.selectionEnd = end + intsertString.length;

  return sentence;
};

export default insertToTextArea;

great job, my friend
