Hello. thanks for your contribution but are you aware those websites change domain like 2 times a week and it will be a pain to maintain ?

If you really want i can review the code, there are quite some things to fix :)

Ofcourse you can review the code, is this what Github was made for?
Not gonna lie I made this for an one time download so I didn't aware they change their domain so frequently, but if we can somehow get the image link directly without the domain regex that would be great.
The image link is stored directly on the website in a script tag starts with ts_reader.run. Its in plain text for Eros but for Terno its in base64
For the site URL, I think all those domains are aliases to each other.

Speak of the devil they just changed their domain

1. Pay attention to indentation, use things like eslint
2. Those sites use a theme we call "Mangastream" look for similar websites in source code base instead of reinventing the wheel :)
