💡 Bulb

While working on side projects I often come with ideas about projects that could make my life easier if they would exist. This repo is my attempt for documenting such ideas.

Inspiration exists, but it has to find us working.

GUI for quick prototyping using javascript proxies.

The idea is to make something like dat.gui but using proxies to trigger updates when the objects change. Also it would be great to make it extensible and allow to create new controls.

Draft API

// The entire ui is generated from an object
const uiDefinition = {
  camera: {
    type: 'folder',
    position3D: {
      type: 'coordinates',
      name: 'Position 3D',
      range: {
        x: [-1000, 1000],
        y: [0, 1000],
        z: [-500, 100]
      },
      step: 1,
      value: { x: -150, y: 280, z: 400 },
      updateFn: _updateCameraPosition
    },
    position2D: {
      type: 'coordinates',
      name: undefined,      // Name is deduced from the key if it is not defined
      range: [-1000, 1000], // Same range for all axis
      step: 1,
      value: { x: -150, y: 280, z: 400 },
      updateFn: _updateCameraPosition
    },
    zoom: {
      type: 'value',
      range: [0, 10],
      step: 0.01,
      value: 7,
      updateFn: _updateCameraZoom
    }
  },
}

const ui = new ProtoUI(uiDefinition)

// Retrieve the params object
const { camera } = ui.getParamsObject()

// Access to a property
const { x, y, z } = camera.position3D

// Modify a property directly (triggers an update)
camera.position3D.x += 30
