Upload Image

Less than 1 minute...

This cookbook guides you on how to set up your own image service to upload images in comments.

@waline/client provides the imageUploader option. You should handle the image object passed in by the client by yourself, and after uploading the image yourself, return an image address through Promise.

Demo

An example of using the lsky-pro graph bed.
