Ivy Renderer (beta) #21706
Description
Overview
Ivy is a new backwards-compatible Angular renderer focused on further speed improvements, size reduction, and increased flexibility.
Ivy is currently not feature complete, but can be tested via enableIvy: true angularCompilerOptions flag.
We currently expect Ivy to remain behind the flag until it's feature complete and battle tested at Google. In the meantime you can check out this Hello World demo.

I'm sorry to ask here (If you consider this spam, feel free to remove it), but does Ivy renderer aim at improving the runtime perf? The only info I found so far is the new features regarding i18n and the fact that it should be backward compatible. Can anyone point me toward info related to Ivy? Thank you.

@Ploppy3 follow Rob on Twitter https://twitter.com/robwormald/status/961445453391790080 it also shrinks the build size e.g.

@avatsaev The new
Featurefeature almost provide the same openness (against class factory), by transforming the type (and compiled metadata) itself during runtime.Even the
OnChangeshook is now an emulated feature, rather than real life-cycle hooks recognized by Angular.chaosmonster commentedon Feb 11, 2018
@avatsaev that is already possible if I understand you correctly https://gist.github.com/chaosmonster/f2576bbd1bc9a50282a2b3b492195b29

I remember reading that current ivy is doing backward compatibility, so that's why there's extra size and time, bit as new versions release and libraries fix compatibility they can drop the dead weight so to speak.

Hi! A question: will
markDirty<T>(component: T)anddetectChanges<T>(component: T)be public APIs? As of release 9-rc1 they are not. Thankssergey-morenets commentedon Nov 12, 2019
Hi
The same question about renderComponent function. Will it be used in Angular 9? Angular 8 Ivy samples used it for bootstrapping. But I see in new Angular 9-rc-1 application that's absent:

Is Ivy compatible with universal?
I tried to download the example https://next.angular.io/generated/zips/universal/universal.zip and execute
ng update @angular/cli @angular/core --nextto upgrade to angular 9.After the upgrade I can run
npm run build:ssr && npm run serve:ssr, but when I try to navigate to the main page at localhost:4000 I get this error:Do you have any suggestions?
naveedahmed1 commentedon Nov 12, 2019
Yes IVY works fine with SSR/Universal, we're using it on our website without any issue.

I just created a Hello World using Angular 9.0.1 (Ivy and AOT with build --prod), with no CSS and no Router. The final size on the browser was 135Kb.
Is that correct?
Thank you for your help!

Given that ivy landed as a default renderer in v9, it is time to close this issue :-)
