Hi HN,I’ve been working on Flowscape, a 2D canvas engine focused on building interactive editors and visual tools. It provides low-level control over scenes, nodes, and interactions without enforcing a specific UI or workflow.The goal is to give developers a flexible foundation for custom editors, diagrams, and canvas-based interfaces. I’d love feedback on the API design, architecture, and real-world use cases.Demo: https://flowscape-ui.github.io/core-sdk/?path=/story/interac... GitHub: https://github.com/Flowscape-UI/core-sdk

Could you build this?
Partial Building a custom, performant 2D canvas rendering engine with scene graphs, spatial indexing, and transform pipelines requires specialized graphics programming.
What it would actually take: Building this requires TypeScript with HTML5 Canvas/WebGL/WebGPU, implementing a robust scene graph with hierarchical affine transforms, a spatial indexing tree (e.g., R-tree or QuadTree) for viewport culling and hit testing, and dirty-rectangle rendering. It also requires building an event propagation system and high-performance zoom/pan viewports. Developing this demands deep experience with low-level graphics math, rendering pipelines, and memory optimization.
