## Summary - Add `/api/projects/:id/upload` endpoint for multipart file uploads with automatic dedup naming - Wire `onImportFiles` from Assets tab "Import media" button through to the upload API - Add global drag-drop overlay — drop media files **anywhere** in the studio, not just the Assets panel - Files that already exist get `(2)`, `(3)` suffixes instead of overwriting - Support uploading into subdirectories via `?dir=` param — dropping on a folder imports there - Make folders draggable in the file tree + support drop-to-root - Add `bodyLimit` middleware for early rejection of oversized payloads - Surface skipped/failed uploads via toast notification instead of console-only Addresses feedback: _"Wish I could upload/drag-drop assets directly in the Studio (music, images, video) like a CapCut media panel"_ ## Test plan - [x] Open studio, drag an image/video/audio file onto any part of the UI - [x] Verify the drop overlay appears with "Drop files to import" message - [x] Drop the file — verify it appears in the Assets tab and file tree - [x] Drop a file with the same name — verify it gets a `(2)` suffix - [x] Click "Import media" button in Assets tab — verify file picker works - [x] Import multiple files at once via drag-drop - [x] Drop a file onto a nested folder in the file tree — verify it lands in that folder - [x] Drag a folder in the file tree and drop it on another folder or root — verify it moves - [x] Drop a file >500MB — verify toast notification appears - [x] Verify drag overlay doesn't get stuck when dragging over nested UI elements
@hyperframes/core
Types, parsers, generators, compiler, linter, runtime, and frame adapters for the Hyperframes video framework.
Install
npm install @hyperframes/core
Most users don't need to install core directly — the CLI, producer, and studio packages depend on it internally.
What's inside
| Module | Description |
|---|---|
| Types | TimelineElement, CompositionSpec, Asset, canvas dimensions, defaults |
| Parsers | parseHtml — extract timeline elements from HTML; parseGsapScript — parse GSAP animations |
| Generators | generateHyperframesHtml — produce valid Hyperframes HTML from a composition spec |
| Compiler | compileTimingAttrs — resolve data-start / data-duration into absolute times |
| Linter | lintHyperframeHtml — validate Hyperframes HTML (missing attributes, overlapping tracks, etc.) |
| Runtime | IIFE script injected into the browser — manages seek, media playback, and the window.__hf protocol |
| Frame Adapters | Pluggable animation drivers (GSAP, Lottie, CSS, or custom) |
Frame Adapters
A frame adapter tells the engine how to seek your animation to a specific frame:
import { createGSAPFrameAdapter } from "@hyperframes/core";
const adapter = createGSAPFrameAdapter({
getTimeline: () => gsap.timeline(),
compositionId: "my-video",
});
Implement FrameAdapter for custom animation runtimes:
import type { FrameAdapter } from "@hyperframes/core";
const myAdapter: FrameAdapter = {
id: "my-adapter",
getDurationFrames: () => 300,
seekFrame: (frame) => {
/* seek your animation */
},
};
Parsing and generating HTML
import { parseHtml, generateHyperframesHtml } from "@hyperframes/core";
const { elements, metadata } = parseHtml(htmlString);
const html = generateHyperframesHtml(spec);
Linting
import { lintHyperframeHtml } from "@hyperframes/core/lint";
const result = lintHyperframeHtml(htmlString);
// result.findings: { severity, message, elementId }[]
