Therefore, the choice was made to make our feature section in the form of an npm package in order to abstract as much as possible from the main application. Together with another frontend developer, we chose new technologies that are more suitable for our tasks. We made a new code guide and used a whole different project structure. We also covered 70% of the code with unit tests, set up CI/CD, wrote documentation. We worked in the "startup" mode, as we made MVP in a short time, the project was successfully completed before the end of the deadline. After leaving the project, other teams still adhere to our methodology, we served as a good example for everyone. Show less
