Does Text Fill Wave work in Next.js App Router?

Yes. The component includes the `'use client'` directive and uses `useGSAP` for proper cleanup across Server Component re-renders. Drop it into any page or component inside `app/`.

Does Text Fill Wave work with Server Components?

The component itself runs on the client (it needs the DOM for GSAP), but the parent page can be a Server Component. Import the component normally; React's "use client" boundary handles the rest. No additional configuration needed.

Does Text Fill Wave work in React 18 and React 19?

Yes. The component uses `useGSAP` which is React-version-agnostic. It also handles Strict Mode double-invocation correctly via `gsap.context` scoping.

Will the animation flash before hydration?

Brief flash is possible on first paint because GSAP needs the client to initialize. The component sets the parked ("starting") state via `gsap.set` on mount before the first frame, so any visible jump is sub-frame and rarely perceived. For above-the-fold use, pair with a CSS opacity:0 default that the component clears on mount.

GSAP component for React

Text Fill Wave in React.

A big headline that fills in color as it enters the viewport, with a bright accent wave riding the edge of the fill line by line. Can also be tied to the scrollbar.

Install

Install Text Fill Wave in your React project

Text Fill Wave ships as a copy-paste React component. The only dependencies are GSAP and the official @gsap/react adapter for the useGSAP hook. Both work in Next.js (App Router and Pages), Vite, Remix, and Create React App.

Integrate

Where it goes in your React app

Text Fill Wave is a leaf-level interactive component, so it needs to render on the client. In a Next.js App Router project, add the 'use client' directive at the top of the file (it's already there in the component you copy).

The component is self-contained: it manages its own refs, useGSAP scope, and cleanup. Mount it inside any Server Component, Client Component, or page. It does not require a provider or wrapper.

If your project uses TypeScript, the component is typed - the props it accepts match the data-anm-* attributes documented on the main detail page.

Gotchas

Colors are CSS custom properties on the root

colorFrom/colorTo/colorAccent are applied as inline style custom properties on the section - the gradient template in the CSS file references them, JS only ever tweens the numeric --tfw-fill property.

One timeline, not two ScrollTriggers

Both lines' --tfw-fill tweens live on a single paused timeline - line two starts at a position offset (lag) rather than getting its own trigger. One ScrollTrigger either plays it on enter (default) or scrubs it when the scrub prop is set.

Rebuild on font load

SplitText needs the real font metrics to produce correct line breaks - the effect gates on document.fonts.ready before splitting.
