Needle Engine is a web-based runtime for 3D apps. It runs on your machine for development with great integrations into editors like Unity or Blender - and can be deployed onto any device! It is flexible, extensible and networking and XR are built-in.

// 3) Webpack where global defines are not made BUT declare const variables are replaces with the actual value (via the webpack DefinePlugin)
