How can i create an extension?

[FOSSEnjoyer69]

i have look far and wide for resources on this topic, all i have found is this https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki/Developing-extensions, which i don't understand at all, i tried reading the source code of extensions but i am completely stumped, i do understand python but i am just completely lost on how to get started.

Any and all help is appreciated.

depends on what type of extension that you want to create

one way to learn is to just look at other extensions
and try to understand how they hook into web UI

image generation pipeline extensions
post-processing module extension
additional future extensions

there's a specific structure that you need to follow in order for whatever you would recognize it as extension
namely there needs to be a scripts dir if you are doing sftuff with python
a javascripts dir

if you're trying to create a image generation pipeline extensions essentially what you need is to create a python script in scripts dir and in this script you create a class that extends scripts.Script in this class there are lost of callbacks you can use to add stuff to the gen pipeline

if you are post-processing module extension, it;s similer but you need to extend scripts_postprocessing.ScriptPostprocessing

for other things like if you wish to add a new tab then you would need to use certain callbacks in callbacks like callbacks_ui_tabs

---

I suggest you try to learn by putting some breakpoints in extensions that you already used and tried to understand them
without knowing what you actually want to do it's hard to give you more help

what type of extension should i create first, for the experience of creating one?

[w-e-w]

if stable diffusion is what you're interested then image generation pipeline extensions
if you're interested in other things then use the other two depends on the type

image generation pipeline extensions is also split into two categories

• AlwaysVisible extensions like most of the extension that you see as a accordion in txt2img and img2img tab
• drop down script scripts like xyz grid

i'm just looking to create a basic extension that does anything (hell, something as simple as dragging and dropping a photo then sending that to img2img), i am completely new to developing stable diffusion extension. the official documentation is pretty bad and there are no resource in terms of YouTube tutorials or step by step guides. i am completely lost

something as simple as dragging and dropping a photo then sending that to img2img

webui is base on gradio
which means if you are interested in interacting with the UI elements then what you should do is look at the gradio docs

When developing webui related stuff it's better that you have understanding of Gradio
especially if you are do UI stuff and not just write them back and functions

the three categories of extensions I listed above are based on how they interact with the core or web UI backend
and not the UI froun end
so basically the categories does not suit your use case if this is what you're trying to do

i was reading through a1111 docs and found this example https://github.com/udon-universe/stable-diffusion-webui-extension-templates/tree/main, i hope this discussion helps people in the future. thanks for trying to help, @w-e-w, if i had notifications i would have seen your reply before digging though docs. again, thanks for the help.
