Sylva

Every prop tunes presentation: speed, color, density, intensity, mode. None of them changes what a scene shows. The words, logos, imagery and motion of a scene are code inside the installed package, so the way past the props is to bring that code into the project, where it is editable like anything else there. The MIT license allows exactly that.

Each component has a locator: node_modules/@designcodeio/threeui/lib-dist/package-components/<ExportName>.js is a one-line re-export whose import names the implementation folder, under lib-dist/shaders/<family>/. That folder's modules import each other by relative path; an import line that reaches into a sibling folder names the other folder to copy along with it. Copying a folder whole is fine: modules the scene never imports are dead weight, not errors. The .d.ts files beside the modules belong in the copy too, since they are what TypeScript reads for these otherwise plain JavaScript files.

Copied into the project's own source tree and imported from there instead of from the package, the component becomes project code. The package stays installed: the @designcodeio/threeui/style.css import keeps sizing the scene to fill its parent, and the package's dependencies keep resolving the copied modules' bare imports (react, and in some scenes three or a pinned build of it).

Inside the copy, the scene itself mostly lives outside the compiled modules. A component that renders a whole document keeps it under sources/ as a template string of plain authored HTML, CSS and JavaScript, and editing that document edits the scene. Shader scenes keep their GLSL in a Shaders.js module beside the component. A component whose delivery includes a copy-into-public step loads its document from public/ instead, so the copied file there is the one to edit.

Sylva renders an iframe pointing at /landing-pages/inner-green-3d.html. That is a URL on your own domain, so your app has to serve that file.

Installing the package puts it in node_modules, which the browser cannot request. Bundlers do not help either: they put modules in your JavaScript, not files on URLs. So the folder has to be copied to where your app serves static files from, public/ in Vite and Next, static/ in SvelteKit.

Copy node_modules/@designcodeio/threeui/lib-dist/assets/landing-pages there, keeping the name. Keep its contents together too: the page loads its fonts, its Three.js runtime and its images from paths beside it.

Sylva takes no prop for this, so /landing-pages/inner-green-3d.html is the only path that works.

Skip it and the iframe requests a URL that is not there, so the component shows an empty box.

Most components in this collection need none of this. They render from the package alone.
