antiSmash run multiple instances of the submission page, depending on whether people want to analyse bacterial or fungal sequences, or run the production or development version. Those sites are very similar, but differ slightly in what features are offered. Currently this causes a lot of code duplication.
This summer I will develop a library that will contain common components from bacterial-ui and fungal-ui repositories. The library will act as common repository not only for these two projects but to other future projects related to antiSmash and beyond.
