I have a situation where I need to render thousands of components inside a wrapper component, but currently only around 300 components are being rendered due to performance issues. How can I achieve this without any rendering delays or performance problems? This image illustrates the rendering time taken by 300 components which is causing issues
If your content is not all visible in the viewport at once, consider utilizing the Proxy Pattern.
An ember addon called "ember-in-viewport" can help you determine if your component is within the viewport or not, allowing you to implement the proxy pattern effectively.
Check out this sample twiddle for a demonstration. By replacing my-component with my-proxy-component in the application.hbs, you could potentially improve page rendering speed by up to 3 times.
These suggestions may seem unconventional but could be beneficial:
Consider implementing lazy loading for certain components, such as loading critical ones first and then dynamically loading the rest after a set time period in the didRender event (during idle state).
For instance:
onDidRender: Ember.on('didRender', function() {
Ember.run.later(() => {
this.set('displayLazyItems', true);
}, 2000);
})
Additionally, opt for inline code instead of creating new components for small items to improve rendering speed.
Analyze a timeline to confirm if performance issues truly stem from render time, as it could also be related to Javascript execution or loading processes.
Lastly, leveraging ember 2.10 with Glimmer 2, the new render engine, can potentially optimize render time by up to 50%, making it worth considering.
