I like node-red's dashboard gauges, but want more flexibility and possibilities for my frontend-apps and now looking for widgets i need. Most available web widgets are for business/text handling, you find less components for technical purpose as dials, gauges, sliders and knobs.
So I ported pure-knob to a new widget I call vue-canvas-knob (vue-knob already exists at npm, but isn't very versatile and I needed to rename it there). Since here are others using node-red and vue I announce it here:
GitHub: [GitHub - ambotaku/vue-knob: Vue Component for Canvas based knob & gauge]
npm: npm install vue-canvas-knob
You'll find this simple "color mixer" demo as part of my GitHub repo.
