Hi there, for the project “Incremental TypeScript Migration for the p5.js Editor”, it mentions that migrating a selected portion of the p5.js editor. Will the client and server folder under the repo be appropriate? I acknowledge that migration of the whole project is not easy and can’t be finished within 200 hours and I’m trying to pick the most suitable option.

Hi @lirenjie95, thanks so much for raising this question!

Yes, pinpointing either the “client” or “server” folder within the p5.js editor repository is an appropriate scope for the TypeScript migration project! Ultimately, your selected scope can be flexible as long as it feels achievable for yourself, and you’re able to produce an overview of how you plan to implement this project over the course of the summer.

Hi there, I wanted to participate in P5.js grant program. The project 2025 pr05 Project List · processing/pr05-grant Wiki · GitHub really inspired me. Can anyone please guide me, how to get started.

Hi! I’ve been exploring the “Desktop Support for p5.js via a New Processing Mode” project and had a quick question. I saw the proof of concept by @stefterv — it’s really insightful and exciting.

Would the selected contributor be expected to build upon Stef’s POC, or is the idea to collaborate alongside him (if he’s involved), or potentially even take it in a new direction based on the goals outlined in the README.md of Stef’s repository?

Hi! Thank you for your interest in the p5.js Mode!

Yes I will be involved. As for the proof of concept, I wrote that to demonstrate what is possible. It is not required to take that exact code as a base. I think we outlined what we expected of the mode in both the Project List and my README.md but if you come up with new ideas please include them in your application. As always, challenging the brief at some level shows clear understanding and research in the project that you are applying to.
