Introduction

Factorio 2.1.11 blueprint-string renderer for browser and Node.js.

fpsr (@rickyzhangca/fpsr) decodes compressed Factorio blueprint strings, resolves connectivity-aware sprite variants (belts, pipes, walls, rails, trains, wires), plans a serializable draw list, and renders to Canvas2D in the browser or Node.js.

It targets Factorio 2.1.11 exactly — vanilla plus Space Age, Elevated Rails, Quality, and Recycler content.

Try the live demo: fpsr.fprints.xyz.

Pipeline

blueprint string
  → decode
  → migrate (1.x → 2.x when needed)
  → resolve (connectivity)
  → planDrawList
  → Canvas2D (atlas sprites from your assets)

Sprite atlases and the render database are not shipped with the npm package. Generate them from a licensed Factorio install, then load them with cdnAssets or localAssets.
