Features

• Create small json objects containing curves infos from After Effect properties
• Supports bezier / hold / linear keyframe types
• Easily read these curves client-side with ae-read-curves
• :warning: Doesn't support color property type & spatial properties like position / curve path

Requirements

• Node >= 8
• After Effects in English
• only tested with CC 2018, but may works with previous versions

Example

const curves = require('ae-export-curves')

// The function will read the current opened project
// and exports chosen property curves
curves({
    // Choose the composition you want to export
    composition: 'Comp 1',
    // You can set a decimal precision
    precision: 5,
    properties: {
      // First item of the array is the layer you want to access to
      // then, just chain sub-properties until you reach the one you want to export
      rotation: ['Shape Layer 1', 'Transform', 'Rotation'],

      // Position is a spatial property. This is not support right now but you can
      // split dimensions in After Effects and use X Position / Y Position
      translateX: ['Shape Layer 1', 'Transform', 'X Position'],

      // For multi-dimensional properties, you must specify which dimension
      // you want to collect by specify an index at last item of the array
      scaleX: ['Shape Layer 1', 'Transform', 'Scale', 0],
    }
})
  .then(json => console.log(json))
  .catch(err => console.log(err))
