Why is this on the top of HN ? Honestly, this is a bad thing, not a thing to show off.

To quote the author: "We're web developers, not iOS developers." EXACTLY, don't bring your web tech into native platforms, learn to do it the right way or just hire someone who knows how to do it.

Seeing things like that creeping into becoming a norm makes me cringe

This is on the top of HN because people, like me, are interested in it. You say learn to do it the "right way", by that logic we should have stuck to making desktop only apps instead of browser based web apps. I'm not saying this is better or worse. But I certainly think it's an approach worth considering.

[mostafaberg]

It's a great piece of tech, I'm not saying anything against that, I'm saying that it shouldn't be used as a replacement for native programming because you don't want to learn a new language. react will come with huge limitations and deps that you don't want to even think about, it's never easy as "code once, deploy everywhere", this is usually a bad decision any company makes, engineering wise.. same reason as adobe air never took off, it's a bad idea, the only reason this is taking off is because people already know JS and don't want to learn something else.

By the "right way" I mean use every language for its intended purpose, you can't build desktop apps in browsers, that's why we have Javascript. and i'm saying we should keep it that way

React Native doesn't claim "code once, deploy everywhere", and in fact embraces native APIs where appropriate. As a reference, their slogan is "learn once, write anywhere". In other words, learn React Native, and write native apps wherever you want. Indeed one of the opening talks about React Native at React Conf specifically mentions that React Native is a leaky abstraction, and embraces that by allowing multiple escape hatches so that the native APIs are always available.

Railing against React Native seems like railing against Unity3d, or saying that abstracting the common parts of mobile development (while leaving the non-common parts 100% available) is a bad thing.

By the "right way" I mean use every language for its intended purpose, you can't build desktop apps in browsers

You can build desktop apps in browsers (ie emscripten). Additionally, can you explain why a "language" (as compared to platform specific APIs) has any relevance to what can or can't be built for a mobile device? For JavaScript specifically, if Apple didn't think that it was a language for building applications on iOS, then why would they ever have release JavascriptCore (which is what React Native uses)?

React is native. It's a JS interpreter on a separate queue rendering native UILabels and UIViews. I'd say the concept is far more superior to UIKit which disgusts me, and I've worked with for almost seven years now. I honestly think React is the future, but for now we can try to stick with MVVM and RxSwift ;-).

I think you're fundamentally not understanding how React (not just React-native) works.

[dcwca]

This is mainly taking off because native developers want a fast build-run loop, hot code reloading, the ability to update code on the device without pushing a new App Store release, and a shared technology and mental model for writing apps across web, iOS and Android.

This is happening.

[rimantas]

No, it is not. "I don't know what I am doing" mentality already hurts the web, where hordes of developers without understanding of the strengths and limitations of the platform are making angular monstrosities, now the same is being pushed to mobile. Luckily it does not have much chances there.

[Apocryphon]

Regardless of your opinions on this, it's still worth examining and discussing.

[tomjen3]

It is on the top of HN because people find it interesting. People are interested in bringing different tech into native platforms to decrease how much it will cost them to develop the product and I for one don't really care if it is not how you are supposed to do "proper development". Once upon a time you weren't supposed to build servers out of commodity components, but it worked alright for google.

> learn to do it the right way

What is the right way? Native only?

There are many apps in the appstore that uses html5 and users of the app don't care how is it build.

I got flamed for my rant.

This is literally just a paid ad for React on the front page. Gross.
