@dotlottie-web Takes Too Long Time to Render Lotties: A Deep Dive into the Issue

Overview

The issue of @dotlottie-web taking too long to render lotties has been a persistent problem for developers, particularly when working with large Lottie files. The problem is not with loading the Lottie files, but rather with the rendering engine. This article will delve into the issue, explore the possible causes, and discuss potential solutions.

Reproduction

To reproduce the issue, please visit the following CodePen: https://codepen.io/henry-hong/pen/gbOxewr. This will give you a firsthand experience of the problem and help you understand the context.

The Problem: Lottie Files with Heavy Size Take Too Much Time to Render

Lottie files can be quite large, and when they are rendered, they can take a significant amount of time. This can lead to a blocked user interaction, which is frustrating for users and can negatively impact the overall user experience. The issue is not just limited to loading the Lottie files; it's a problem with the rendering engine.

The Connection to the PR: "Upgrade dotlottie-rs v0.1.31 wasm bindings"

As mentioned in the GitHub PR https://github.com/LottieFiles/dotlottie-web/pull/350, the upgrade of dotlottie-rs v0.1.31 wasm bindings seems to be related to the issue. This suggests that the problem may be rooted in the way the rendering engine is handling the Lottie files.

The Impact of @dotlottie-web on Other Libraries

@dotlottie-web is used in various libraries, including dotlottie-react, vue, and others. This makes the issue even more complex, as it affects multiple libraries and frameworks. The fact that @dotlottie-web is used in these libraries makes it even more challenging to resolve the issue.

Downgrading the Package: A Temporary Solution

To fix the issue, some developers have resorted to downgrading the version of the @dotlottie-web package. While this may provide a temporary solution, it's not a fundamental fix. The problem still exists, and it's essential to address the root cause.
