What is the footprint of this library in bytes? And is it light on dependencies?

Okay, question: can it perform the following task elegantly? Say, I build a declarative tree describing a layout, and I render it. Now I remove one item from the tree. Can the layout engine efficiently remove the item from the view, and... (now it comes) provide an animation for it? As in, the item slowly losing opacity, then the surrounding items moving closer together? (Or a different animation depending on setting…

Yoga itself does not handle animation but by using another animation system on top of Yoga it should be very possible. I have not yet tried it myself but by wrapping a layout change in a UIView animation block the above should be doable (on iOS but similar should hold on other platforms).

Please do not spread FUD, or at least clearly explain your worries. The patent clause only applies if you sue Facebook for patent infringement in React itself . It's a very clear defensive policy. Despite all the breathless blog posts claiming that you can lose your license for "competing" with Facebook, it is not true. https://code.facebook.com/pages/850928938376556

I never said that you could lose your license for competing against Facebook, I said that you could lose your license if you have a patent and assert it against Facebook if it infringes. This is the patent grant from React, which is identical to the grant in the post's repo as well. The language in the patent grant is pretty clear and doesn't mention anything about React specifically: The license granted hereunder wi…

One thing I've thought about recently is Facebook's Patent grants, and it's one thing that makes me uneasy about using any open source technology from Facebook like React (I currently do but am thinking to move to Preact because of the nicer MIT license and that it's analogous to React in many ways) because they're generally given a patent grant. I'm not a lawyer so I don't know if the grant would hold up in court si…

I am curious to hear of anyone who has reviewed this license with their lawyers / legal departments and received a positive, non-cautionary response to go ahead and use the software and libraries covered under it.

This is one of the reasons companies seek patents, called a defensive patent strategy. The goal is to discourage competitors from suing you for patent violations by making sure you own a patent your competitors are likely to have violated. It creates a kind of "mutually assured destruction" that discourages either party from launching a patent war (this only works against real competitors, not against patent trolls,…

Let's say I have a patent for a technology outside of React, and even outside of software, such as some hardware patent. Why should me suing for infringement of that patent preclude me from using React when it (the patent infringement and React) are completely independent?
