In many software projects, sooner or later, there arises a need to reuse code. Sometimes such code can be extracted into a standalone package that can be maintained independently and easily plugged into other applications. If the package solves a common problem and could be useful to others, it may be worth open-sourcing it. This gives other developers the opportunity to adopt and use your library.

However, preparing open-source code—setting up the repository, CI, and workflows—may often  differ from a company’s internal standards. One of our implemented open source projects was an extension for the popular Django package django-import-export. Using it as an example, we’ll walk through all the steps needed to publish your own library.
