Presented at Node-RED Con Nagoya 2025!
管理人Introduction
In this post, I’d like to look back at "Node-RED Con Nagoya 2025," which took place on October 17th. This was my first time speaking at this annual Node-RED conference. Over the past year, I’ve been developing and publishing Node-RED nodes and contributing to technical books about Node-RED MCU, so I centered my presentation around those experiences.

▼On November 15th, a new supplemental book for Tech Book Fest (Gijutsu Shoten) was published. I contributed a section to it as well.

My Presentation
The video of my presentation is available online. My talk was titled "Cases of Developing and Utilizing Node-RED Nodes, and Engagement with the Community."

▼Presentation slides:
Since the content was quite technical, I was worried it might only appeal to Node-RED experts, but given the audience, I received a lot of great feedback and reactions.
▼It was my first time visiting the venue, "STATION Ai." My slides were projected onto a screen high up on the wall.
During the Q&A, I received a comment regarding importing Ubuntu environments in WSL2. I found this very intriguing and tested it myself later.
▼I can now create multiple Ubuntu environments, which is extremely helpful for setting up different development environments.
Using WSL2 Part 5 (Installing Multiple Instances of the Same Distribution, Ubuntu 22.04)

If I integrate this mechanism into my wsl-ubuntu node, it could become even more versatile. Regarding the node development I introduced in the talk, I have covered those in previous blog posts as well.

In the keynote, it was mentioned that "Node-RED nodes are cute." Indeed, for visual programming tools, design is a crucial element. If I were designing them, I’d probably just stick to simple rounded rectangles without a second thought!
▼This "cuteness" was mentioned several times in subsequent presentations as well.
Networking After the Session
After my talk, some attendees told me they are actually using my nodes in their companies. In particular, they found the python-venv node useful because it allows them to use Python virtual environments and keep the environment setup steps documented within the flow.
I also met someone developing a node to operate the Tello drone, enabling camera feed acquisition and control via Node-RED.
▼The node is here:

I actually received a Tello drone from an acquaintance a while ago, so I’m looking forward to trying this node out.
▼I also attended the after-party!
Finally
It was a great learning experience to interact with experts who have much more experience with Node-RED than I do. Last year, I participated only as an attendee, but I realized that attending as a speaker makes networking much easier because people already know what you are working on. I definitely want to participate again.
▼There is also a Node-RED Advent Calendar for this year. Please check it out if you are interested!
