Learn VELATO with Real Code Examples

Load and display a Lottie-based loading spinner in a Rust GUI app

Animated menu transitions in a Rust desktop application

Interactive infographic with animated vector graphics in a game or data‑visualization app

Web demo via wasm + WebGPU showing exported Lottie animation in browser canvas

Combine Lottie animations with other Vello-drawn shapes for composite UI

Ensure JSON is valid and matches Lottie spec version supported by Velato

Check that Vello backend is correctly initialized (GPU / WebGPU / fallback)

Verify that unsupported Lottie features (text, images, effects) will not render - fallback or skip them

Confirm asset paths and embedding strategy (especially for web build)

Debug rendering output in Vello scene inspector (if available) or browser console for wasm builds

Run desktop example with winit to verify animation playback

Use wasm + WebGPU demo (if browser supports) to test web rendering

Test various Lottie files to detect unsupported features (text, images, effects)

Profile frame rate for complex animations

Check memory usage and asset loading behavior

Native desktop executables (Windows, Linux, Mac) via Rust build

Web deployment via WASM + WebGPU (if supported)

Embed in larger Rust applications or games

Package assets with the app binary or load at runtime

Use continuous‑build pipelines (CI/CD) for app updates

Velato crate

Vello rendering engine

Rust toolchain (cargo, wasm-bindgen for web)

winit (or other windowing backend) for desktop apps

Rust + WebGPU for browser-based animation (experimental)

GUI frameworks built on Vello or winit

Game engines or apps using Rust + Vello + Velato for animated UI

WebAssembly builds for web deliverables

Custom Rust applications needing animated vector content

Potential integration with other Rust crates for UI, input handling, asset loading

Reuse animation components (Composition + Renderer) across app screens

Keep Lottie animations simple to ensure support and performance

Test early on target platforms (desktop, web) for compatibility

Use version control for Lottie assets and Rust code together

Document which animations rely on unsupported Lottie features for future maintenance

Running web builds smoothly due to WebGPU limitations in some browsers

Handling unsupported Lottie features gracefully (fallback or skip)

Debugging rendering issues or performance bottlenecks

Ensuring cross-platform consistency (desktop vs web) in rendering output

Managing asset packaging and deployment in Rust build systems
