I've been working with an agent to make a web-based biofeedback "application" which is really a toolbox of components you can slap together to support

  - heart rate via Polar H10
  - respiration rate via strap-on device
  - GSR and EMG via arduino + web serial
  - radar-based respiration (SOTA says you can get R-R intervals as good as the H10 if you're not moving)

and even do things like a 2 player experience. The code is beautiful, pure CSS the way it was supposed to be, visualizations with D3.js. I do "npm install" and can't get over the 0 vulnerability count. It's coding with React that's 100% fun with none of the complaints I usually have.
