NodeBase64ImageStorage plugin

v0.14.0+

This plugin is used to modify the storage method of node images in base64 format in the data.

Store images in base64 format as' key map 'in the imgMap field of the root node, while other nodes only save' key 'to avoid the problem of duplicate storage of the same image referenced by different nodes. Normal' url 'format images are not processed.

For example, the node data before using the plugin is:

{
    data: {
        text: 'xxx'
    },
    children: [
        {
            data: {
                text: 'xxx2',
                image: 'data:image/png,xxx'
            }
        },
        {
            data: {
                text: 'xxx3',
                image: 'data:image/png,xxx'
            }
        }
    ]
}

After using this plugin, it will become:

{
    data: {
        text: 'xxx',
        imgMap: {
            'smm_img_key_xxx': 'data:image/png,xxx'
        }
    },
    children: [
        {
            data: {
                text: 'xxx2',
                image: 'smm_img_key_xxx'
            }
        },
        {
            data: {
                text: 'xxx3',
                image: 'smm_img_key_xxx'
            }
        }
    ]
}
