Visual: Jessica typing fast, neon code. Jessica: "Netflix uses React and Flow. But what if we built a streaming frontend in Pure TypeScript—no any , no @ts-ignore , and no runtime surprises? Let’s do it. 💎"
I wrapped FFmpeg.wasm with:
Result: If an audio clip tried to call .duration as a video, TS yelled at compile time. No more "Cannot read property of undefined" in prod.

"Entertainment apps crash when types lie. A video player has states: loading , playing , paused , buffering , error . If you mistype a state transition, users see a black screen. We’re going to model the entire player state as a discriminated union."
"Chrome’s Media Session API isn’t fully typed. We'll augment the DOM types to add setPositionState with exact timestamps."
Media creation should be robust. Stop trusting your CLI scripts. Start trusting your compiler. 💎 Visual: Jessica typing fast, neon code
Screen: Code snippet.
"We'll use requestAnimationFrame with a typed callback that updates the UI based only on the current VideoState . If the state doesn’t have currentTime , TS won’t let you access it."
type FFResult<T> = success: true; data: T | success: false; error: string async function trimVideo(file: File, start: number, end: number): FFResult<Blob> Now, no more silent failures. If end < start , the type won't prevent it, but the result type forces you to handle the error. Let’s do it
Why entertainment apps have higher reliability requirements than CRUD apps. A black screen kills engagement.
I replaced any with a union type for clip properties: type Clip = VideoClip | AudioClip | ImageClip
