Custom Dialog for Inserting Images in MDXEditor

[yassersaidi]

I created a custom dialog for inserting images in mdxeditor. This dialog uses Uploadthing for image uploading. Here's the code:

• AddImage Component

const AddImage = () => {
    const insertImage = usePublisher(insertImage$);
    const [openImageDialog, seOpenImageDialog] = useState(false);
    const [imgUrl, setImgUrl] = useState({
        src: "",
        alt: ""
    });
    const [loading, setLoading] = useState(false);
    const { toast } = useToast();

    return (
        <>
            <Button onClick={() => seOpenImageDialog(true)}>
                <ImageIcon size={20} />
            </Button>

            <Dialog
                open={openImageDialog}
                onOpenChange={() => seOpenImageDialog(false)}
                aria-labelledby="Create Note"
                aria-describedby="Dialog to create new note"
            >
                <DialogContent
                    aria-labelledby="Create Note"
                    aria-describedby="Dialog to create new note"
                    className="flex w-full max-w-[520px] flex-col gap-6 border-none dark:bg-dark-1 bg-light-1 shadow-md px-6 py-9"
                >
                    <div className="flex flex-col gap-2">

                            <p className="mt-1 text-2xl font-semibold">Add Image</p>
                        </div>
                        <UploadDropzone
                            appearance={{

                            className="dark:border-dark-border border-light-border"
                            endpoint="imageUploader"

                                        altText: file.name,

                            onUploadError={(error) => {

                                        setLoading(true);
                                        await insertImage({
                                            src: imgUrl.src,
                                            altText: imgUrl.alt,
                                            title: imgUrl.alt
                                        });
                                        setLoading(false);
                                        seOpenImageDialog(false);
                                    } catch {
                                        setLoading(false);
                                        toast({ title: "Can't Add your Image, try again." });
                                    }
                                }}
                            >
                                {loading ? (
                                    <>
                                        <Image
                                            width={28}
                                            height={28}
                                            src="/icons/loading-circle.svg"
                                            alt="Loading"
                                            className='mr-2'
                                        />
                                        Saving
                                    </>
                                ) : (
                                    <>Save</>
                                )}
                            </Button>
                        </div>
                    </div>
                </DialogContent>
            </Dialog>
        </>
    );
};

• Then add the component in the toolbarContent:

toolbarContents: () => (
    <>
        <DiffSourceToggleWrapper>
            <UndoRedo />
            <BoldItalicUnderlineToggles />
            <BlockTypeSelect />
            <Separator />
            <CreateLink />
            <AddImage /> {/* Add it here */}
            <InsertTable />
            <ListsToggle />
            <InsertAdmonition />
            <InsertThematicBreak />
            <YouTubeButton />
        </DiffSourceToggleWrapper>
    </>
);

• in the image plugin:

  imagePlugin({
          disableImageSettingsButton: true,
      }),
  

This code defines a new custom dialog component, AddImage, which allows users to insert images into the editor. The dialog includes both an upload dropzone (using Uploadthing) and fields for manually entering image source and title. Add the component to your toolbarContents to include it in the editor's toolbar.
