This project aims to teach you about building custom interfaces in Factorio. It does so in two parts: First, a chapterized tutorial that guides you through the process, starting at the very basics of element creation and interaction handling. Second, it provides a loose collection of advanced topics that you can use to expand your knowledge.
The actual tutorial is found in this project's Wiki!
If you have any suggestions for topics that should be covered, ideas for improvements of any kind that could be made, or problems that need to be fixed, please open an issue or pull request. I'm open to any kind of feedback.
The Factory Planner Discord has a dedicated channel for this project, so feel free to join if you prefer to talk to me that way.
This tutorial and the associated code is in the public domain, so feel free to use it in any of your projects.
