I generated a brand new project using ember-cli (v1.13.8) and upgraded to Ember as follows:
* * *
## Ember: 2.1.0 Ember Data : 2.1.0 jQuery : 2.1.4
When I declare components using angle-bracket syntax in my template, nothing is rendered. But using curly braces works just fine.
Are angle bracket components supported in Ember 2.1.0? Is there a default config step that I am missing?
Thanks!

I believe they are only in canary for now, and should appear in 2.2. Someone correct me if I am mistaken.

Just curious: Besides the syntax, what is the added benefit of angle-bracket components?

I believe I read somewhere that one-way binding is default with angle components. However I’m not finding the article right now.

Ahh. Good to know. I mistakenly thought they were already in 2.1.0.
Any ideas about when Glimmer Components might land? I’ve got an app that renders lists of 1500 items and I have noticeable perf issues with render.
I know using pagination and/or cloaking is the right way to go when dealing with large data sets, but I was secretly hoping that Ember would be able to render a couple of thousand list items without intervention on my part.

@mayankbpatel I don’t think angle bracket components will solve that. I would suggest you use ember-collection: [GitHub - adopted-ember-addons/ember-collection: An efficient incremental rendering component for Ember.js with support for custom layouts and large lists](https://github.com/emberjs/ember-collection)

You’re mistaken 🙂 Per this pull request it’s going to be a bit longer: [[WIP] Glimmer Components guides by chancancode · Pull Request #764 · emberjs/guides · GitHub](https://github.com/emberjs/guides/pull/764)
2.2 is going to have changes under the hood, but nothing that we’re going to see as end-users. Docs are going to be almost identical, but we’re hoping to update the design for 2.2
