How do I change the animation speed in ng-lottie?

Use the setSpeed() method on the animation instance, accessed through the animCreated event. The demo shows binding a range input to adjust speed dynamically, making it straightforward to implement interactive controls.

ng-lottie vs using lottie-web directly in Angular: which is better?

ng-lottie offers a component-based abstraction that simplifies Angular integration with less boilerplate, but using lottie-web directly provides more low-level control. Choose ng-lottie for idiomatic Angular patterns or lottie-web for custom implementations.

Can I use ng-lottie in an Ionic app?

Yes, the README links to an Ionic Lottie project demonstrating integration. Since Ionic is built on Angular, ng-lottie should work, but you may need to handle performance considerations for mobile platforms.

Where can I find free Lottie animations for ng-lottie?

Websites like LottieFiles offer a vast library of free JSON animations. Download these files and load them via the path option in ng-lottie's configuration, as shown in the demo with assets/pinjump.json.

How do I handle animation events like onComplete in ng-lottie?

The animCreated event provides the animation instance, where you can use standard lottie-web event listeners, such as addEventListener for events like complete or loop, enabling advanced interaction handling.

Does ng-lottie support server-side rendering with Angular Universal?

Since lottie-web relies on browser APIs, ng-lottie may cause errors in SSR. You'll likely need conditional loading or placeholders to avoid issues during server-side rendering.

Lottie Animation — Angular Lottie Animation Wrapper

What is Lottie Animation?

ng-lottie is an Angular library that renders After Effects animations exported as JSON files in Angular applications. It wraps the lottie-web library to provide a component-based interface for displaying vector animations with interactive controls. This solves the problem of integrating high-quality, scalable animations without relying on large video or image files.

Target Audience

Angular developers looking to add rich, interactive animations to their web applications, particularly those using After Effects for design and needing a performant, vector-based solution.

Value Proposition

Developers choose ng-lottie because it offers a seamless Angular-specific integration for Lottie animations, with easy configuration and full programmatic control. It leverages the widely adopted lottie-web library while providing an idiomatic Angular component API.

Render After Effects animations on Angular based on lottie-web

Use Cases

Best For

Adding interactive animations to Angular dashboards or data visualizations
Integrating designer-created After Effects animations into Angular apps
Building animated UI components like loaders, icons, or illustrations
Creating engaging marketing or landing pages with vector animations
Implementing animations with programmatic playback control (play, pause, speed)
Reducing animation file sizes in Angular projects compared to GIFs or videos

Not Ideal For

Projects that require animations without any JavaScript dependency, such as pure CSS or SVG animations.
Teams using design tools other than Adobe After Effects for creating animations.
Applications where server-side rendering is critical and client-side JavaScript must be minimal.
Prototypes or simple apps where the overhead of integrating Lottie and Angular is not justified.

Pros & Cons

Pros

Angular-First Component API

Provides a declarative <lottie-animation-view> component that integrates seamlessly with Angular's template syntax, as shown in the demo code with easy property binding and event handling.

Comprehensive Playback Control

Exposes methods like play(), pause(), stop(), and setSpeed() for dynamic manipulation, demonstrated in the component example for interactive animation management.

Vector Animation Efficiency

Leverages JSON-based animations from Lottie, ensuring small file sizes and scalability without pixelation, as highlighted in the README's emphasis on reducing bundle impact.

Flexible Rendering Options

Supports multiple renderers (SVG, canvas, HTML) via the underlying lottie-web library, allowing optimization for different use cases based on configuration options.

Cons

Tight Coupling to After Effects

Animations must be created in After Effects and exported with bodymovin, limiting design flexibility if teams use other tools like Figma or CSS animations.

Dependency Chain Risks

Being a wrapper around lottie-web, any issues or breaking changes in the base library can directly affect ng-lottie's stability, and the README does not specify version compatibility or update policies.

Potential Maintenance Gaps

The README mentions renaming after Angular 4 support, and with limited recent activity indicators, it might lag behind newer Angular versions or lack active community support.
