Developer Builds Custom 3D Library in Three.js After Hitting Level Editor Limits

A developer working on a project called Oniria has built an interactive 3D library where DEV Community articles are represented as physical books on browsable shelves. The concept shifted away from an earlier cyberpunk city aesthetic after the creator concluded that a library better reflected how articles are naturally organized, with rooms mapping to categories and shelves to collections. Constructing the entire environment through Three.js code alone — without a live level editor — quickly became unmanageable as the space grew more complex. Placing and adjusting objects required manually editing coordinate values, saving, reloading, and walking back across the scene to evaluate each change. This friction ultimately pushed the developer to begin building their own in-world authoring tools to streamline the workflow.
