Feature Request: Image upload

[fasthold]

Editor lacks of image uploading function, it's an essential feature in rich editing.

Wish this will be shown in the demo example.

Thanks.

Image uploading is a tight integration process between the back-end and a front-end. This library (as well as TipTap) are front-end only libraries. They do not know how to upload to a server and that process can be as diverse as it gets.

Best that can be done by a front-end library is image insertion from a URL and then styling that with different styles and crops.

Keep in mind that Gutenberg is a library that has super-tight-integration with WordPress and the image upload process is very well known in comparison to this library, which doesn't assume what server architecture you have.

You can enable <img> elements by adding the Image extension and then have it in the :extensions="[Image]" prop. Then you need to create a block/inline tool to suit your back-end needs that can upload to your server and finally you can use the resulting url to insert the image into the editor:

  editor
    .chain()
    .focus()
    .setImage({
      src: url,
      alt: alt || undefined,
      title: title || undefined,
    })
    .run();

Having said all that - my latest project's server is on Directus, and my front-end is on Nuxt, so I can add a file upload input that is scoped to certain file types, then handle the upload when the user picks a file and the server gives me a file object:

<script setup lang="ts">
const props = defineProps<{
  editor: Editor;
}>();

const input = ref<HTMLInputElement | null>(null);

const assetsBase = "https://api.myserver/assets";

const handleFiles = async () => {
  const { files } = input.value || {};
  const [first] = files || [];
  if (first) {
    const data = new FormData();
    data.append("file", first, first.name);
    const result = await useDirectus<DirectusFiles>(uploadFiles(data));
    const { id, title } = result;
    const url = `${assetsBase}/${id}`;
    props.editor.chain().focus().setImage({ src: url, alt: title || undefined, title: title || undefined }).run();
  }
};
</script>

<template>
  <!-- other stuff like show preview of previous upload and wrap the input below, since it is visually hidden -->
  <input
    ref="input"
    accept=".jpg,.jpeg"
    type="file"
    class="absolute inset-0 z-[2] w-full cursor-pointer appearance-none border-none opacity-0 focus:outline-none"
    @change="handleFiles"
  />
  <!-- other stuff like upload button, upload progress, errors, deletion -->
</template>

As you can see - my process is most probably super specific to my needs and cannot be applied for everyone.

@johnpuddephatt - I wonder if the demo can show use of an Image by simply asking for a URL.

[avioli]

@fasthold Alternatively you can use an upload image extension like this one: https://github.com/carlosvaldesweb/tiptap-extension-upload-image

[johnpuddephatt]

Agree with both of you! Like @avioli says it is project specific, but we should show a couple of examples in the demo – perhaps the tiptap extension linked to plus a custom solution using a Vue component that uses something like FilePond as I think this will demonstrate how easy it is to do something custom.

[avioli]

@johnpuddephatt That's a very good idea, although I've used FilePond in a couple of projects and I'm not sure it will work great within a contenteditable area, but I'll be happy to be proven wrong!
