Okay, the current bash script works now. You can check out by just npm i then you have everything.

The only leftover thing is reworking the bash script to make it looks more professional. at the same time, you can review it.

The script doesn't work for me. There's no content in the submodule. What do I need to do?

[hueitan]

Ok, it should work now in one command npm i

[stephanebisson]

Doesn't really work for me. The images are always embedded.

This PR will require another update to replace most of the bash script (compiled js and css part) after this wikimedia/wikipedia-preview#113 is done.

This path is problematic. Different setups can have different url structures. Plugins are expected to call php functions to get info like this.

A simple way to work around that is to put the images dir under the styles dir and use urls like images/xxx.svg. However, since we don't include the style as a file but as an inline <style> tag created by js, the style relative path is the document, which is close to the root, far away from the plugins.

make sense, the update is here 2d46a13
