Slava, Horizon looks cool, and I'm a huge fanboy of RethinkDB. However, in the demo video you write queries client side. How do you protect against users modifying front-end JavaScript and thus the queries? // ex this.props.horizon.order('datetime', 'descending').limit(8).watch()

This is the question I always get stuck on with these "front-end only" frameworks. How do you prevent DoS attacks or scrapers downloading your whole database? What is the information security model?

I would think you'd do this server-side, I've had similar issues outside of JavaScript: users play a game and create a custom client that connects to my server, they send custom packets thereby I have to make sure that they: don't access too much data at once (a user asking for 100 different things in 3 seconds is not even normal in certain scenarios) or the data they're requesting is formatted wrong (a string where a integer is expected?) the solution I guess is server-sided. This issue isn't unique only to client-side javascript, it is relevant in networking as well. So long as the back-end is designed intelligently it could all work out.

For apps that don't necessarily have the realtime requirement, Kinto [1] is another really cool open-source backend solution that focuses on the offline-first scenario. It's built by the Firefox Sync team and used in production at Mozilla.

That said, at first glance there doesn't seem to be anything stopping anyone from building a caching layer on top of Horizon to enable offline-first functionality. Definitely going to be keeping an eye on this as well!

EDIT: It looks like they are in fact considering offline-first support already [2]!

I'm really excited to see a framework make security and authentication part of it's foundation.

Amazing work Horizon team!

I think it's amazing that it's working with real RxJS streams for changes now - given how Redux store now returns an observable thing, Cycle is Rx based and Angular 2.0 uses a lot of Rx. This guarantees that things will interop nicely with eachother and we'll be able to use Rx all around.

You might want to check out lovli.js ( https://github.com/flipace/lovli.js ) -- a Horizon+Redux integration. It's really cool and demonstrates how well Horizon can interop with modern web technologies.

Oh, this is exactly what I want to do with Horizon! So cool.

I'm intrigued but after reading a couple of pages it's not really clear to me what benefits I get or really exactly what this is....

Why should I use it over my current approach ? Why is this compelling?

I'm wondering how this works (or if it does) with GraphQL subscriptions. https://github.com/rethinkdb/rethinkdb/issues/3711

There's currently no GraphQL support in Horizon, but it's on the roadmap. See https://github.com/rethinkdb/horizon/issues/125 .

Thanks!

> Horizon is built on RethinkDB, a massively scalable, open-source database capable of millions of realtime updates per second.

Have there been any performance benchmarks or reviews of RethinkDB yet? Especially at this scale?

Thanks for your time! Could you give me a quick comparison of Horizon and Meteor? I've used Meteor in the past (and loved it), and it looks like Horizon might be fun to learn.

There's one on the website: http://horizon.io/faq/

IMO it hand waves Meteor away without acknowledging (perhaps out of ignorance) some of it's other strengths.

I'll watch Horizon but I'm taking it all with a grain of salt. Standard new javascript framework protocol people.

Think of it as an open-source Firebase. Not only you can host your own data, you can also do complex queries because it uses RethinkDB underneath.

If you're looking for a way to check out Horizon and don't already have RethinkDB up and running locally, we've put a One-Click app together over on DigitalOcean: https://www.digitalocean.com/community/tutorials/how-to-use-...
