* refactor: extract @hyperframes/lint package from core Moves all lint rules, hyperframeLinter, lintProject, and related types from packages/core/src/lint/ into a new standalone packages/lint package. Core keeps a thin re-export stub at @hyperframes/core/lint for backward compatibility. Consumer imports (cli lint command, producer hyperframeLint) are updated to import from @hyperframes/lint directly. Depends on @hyperframes/parsers (PR #1755). * fix: restore postcss-selector-parser in core (sourceMutation.ts still uses it) * fix(ci): add parsers+lint to Dockerfile and build before preview tests * chore: update bun.lock after restoring postcss-selector-parser dep * test(cli): update lintProject test for string-dir signature from @hyperframes/lint * refactor(core): single-source the lint engine in @hyperframes/lint Delete core's byte-identical copy of the lint rule engine and re-point staticGuard at @hyperframes/lint, so the render-time render-gate and the studio preview share one rule engine instead of two copies that could silently diverge. Back-compat preserved via the @hyperframes/core/lint stub. Addresses review feedback on the dual-copy footgun.
@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 }[]
