opencut-wasm

Shared video editor logic compiled to WebAssembly. Used by the OpenCut web app.

Install

npm install opencut-wasm

Usage

import { formatTimecode, mediaTimeFromSeconds } from "opencut-wasm";

const ticks = mediaTimeFromSeconds(1.5);
const label = formatTimecode({ ticks });

All exports are documented in the TypeScript definitions.

Source

Functions are implemented in Rust under rust/crates/. This package is the compiled WebAssembly output — do not edit it directly.

Local development

The web app depends on the published opencut-wasm package by default. If you are editing the WASM source in this repo and want apps/web to use your local build instead:

# From the repo root
bun run build:wasm

cd rust/wasm/pkg
bun link

cd ../../../apps/web
bun link opencut-wasm

While you work, rebuild on changes from the repo root:

bun dev:wasm
