1) Generate a private key and certificate signing request:

openssl genrsa -out ios_distribution.key 2048
openssl req -new -key ios_distribution.key -out ios_distribution.csr -subj '/[email protected], CN=Example, C=US'

2) Upload CSR to apple at: https://developer.apple.com/account/ios/certificate/create
   - choose Production -> App Store and Ad Hoc

3) Download the resulting ios_distribution.cer, and convert it to .pem format:

Demo: Coordinating async React with non-React views

tl;dr I built a demo illustrating what it might look like to add async rendering to Facebook's commenting interface, while ensuring it appears on the screen simultaneous to the server-rendered story.

A key benefit of async rendering is that large updates don't block the main thread; instead, the work is spread out and performed during idle periods using cooperative scheduling.

But once you make something async, you introduce the possibility that things may appear on the screen at separate times. Especially when you're dealing with multiple UI frameworks, as is often the case at Facebook.

How do we solve this with React?

// funciona somente com v3.1.6, essa estrategia de end/continue
// era um backdoor para fazer recursao em types, recursao funcionava somente com interfaces
// antigamente pela resolucao de tipos ser lazyness e nao acabar fazendo o compiler cair
// potencialmente em um looping infinito na resolucao do tipo, por causa disto tem validacao
// no compiler agora e codigos nesse estilo sao barrados pelo compiler
