This is the first release with the new monthly cadence, so 0.40 is known as December 2016. The next version will be 0.41 - January 2017, and will be released at the end of the month.
This change affects all native modules and application code on iOS that refer to react native
.hfiles
After e1577df, Native code on iOS must refer to headers out of the react namespace. Previously the following would work:
#import "RCTUtils.h"
But now all headers have been moved:
#import <React/RCTUtils.h>
This means that all iOS native libraries need a major version bump for RN 0.40. We attempt to minimize changes of this magnitude, and we apologize for any inconvenience caused.
Support for require('image!…'), which has been deprecated for a long time, is now removed. If you are still loading images that way in your apps, make sure to check the documentation for alternatives.
If you were having custom rn-cli.config.js in your app and for some reason, using getTransformModuleOptions, make sure to check @davidaurelio commit ca58e0a for details on the changes.

Hyperloop is a great approach for Ruby developers who want to use React but aren’t willing to spend a lot of time learning and mastering JavaScript. I have always liked Ruby and a language so I can imagine if I spent several years working in Ruby that I wouldn’t want to have to split my time between writing Ruby on the backend and then JavaScript on the frontend. So while I won’t be using Hyperloop, I think it could be great for Ruby devs. Although, the translation from Ruby to JavaScript could be tricky and/or cause compatibility issues in the future. Looking at the Get Started guide, I do like the elegance of writing Ruby code to implement React components:
class HelloWorld < React::Component::Base
param :time, type: Time
render do
p do
span { "Hello, " }
input(type: :text, placeholder: "Your Name Here")
span { "! It is #{params.time}"}
end
end
end
every(1) do
Element["#example"].render do
HelloWorld(time: Time.now)
end
endThey have a bunch of great tutorials and one of the first ones I wanted to look at was how life-cycle methods are implemented. They changed things a bit and went with before_mount, after_mount, after_udpate instead of componentWillMount, componentDidMount and componentDidUpdate. Not exactly sure why they changed the methods.
Again, interesting concept and great for existing Ruby devs.
The React team just announced the availability of React 15.4.0 – lots of changes with the major one being the explicit separation of React and React DOM. It should be a seamless change if you’ve been using a recent release of React. There’s also some updates to profiling your app in Chrome Dev Tools. The release notes can be found on GitHub, but here are the highlights:
aria- attributes. (@jessebeach in #7744)autofocus rather than autoFocus. (@hkal in #7694)String.prototype.split. (@nhunzaker in #7629)batchedUpdates API now passes the wrapped function’s return value through. (@bgnorlov in #7444)Simulate.click() on a <input disabled onClick={foo} /> then foo will get called whereas it didn’t before. (@nhunzaker in #7642)ReactTestRenderer.create() now accepts {createNodeMock: element => mock} as an optional argument so you can mock refs with snapshot testing. (@Aweary in #7649, #8261)
Not a great series of updates from GoPro, from missing revenue expectations by 23% and now issuing a recall for 2,500 Karma drones which is GoPro’s newest product which enters the drone space. From the official announcement:
GoPro is committed to providing our customers with great product experiences. To honor this commitment, we have recalled Karma until we resolve a performance issue related to a loss of power during operation. We plan to resume shipment of Karma once the issue is addressed.
It’s a scary thought to have your $800 drone suddenly lose power while in the air and just start crashing to the ground. But another interesting point is that there has only been 2,500 drones sold. I’m curious how many people decided to go with the DJI Mavic instead of the Karma. I was leaning towards the Mavic personally but the price increase was making me a little hesitant. But with this news, I’m definitely a Mavic supporter now.
NodeJS v7.0.0 has been released and we have finally moved on from the v6. I don’t think there are a ton of “major” changes here but I’m hoping v7 will become the defacto LTS version going forward. The updates for V8 are also promising and hopefully have some performance improvements. Here are the notable changes:
Buffer
Child Process
Cluster
Deps
File System
Intl
Promises
Punycode
punycode module has been deprecated #7941.URL
You can take a look at what the HackerNews community is saying about the latest release here.
I’m a little behind on blogging, so this is a little old but it’s definitely worth mentioning again. If you’re building web apps and need map capabilities, you should definitely take a look at Leaflet. Leaflet is now at v1 so that’s a great sign for anyone using Leaflet. I also like how the first item on the changelog is that they have made major performance improvements. It’s a great sign from the team when that’s the first thing the highlight. The full list of changes in this release are:
L.Tooltip class for all your dynamic labeling needs.map.flyTo).map.setZoom(12.34)).The update also discusses a new release cycle to help improve the speed of releases. After paying down some major technical debt, it looks like the team will start to release more updates frequently. And it’s great to see that they’re already releasing more often. Leaflet v1.0.1 has already gone out.
And there are some other initiatives they are going to pursue:
DJI just announced their answer to the GoPro Karma and it’s smaller with more features but also costs more. I really like how the Mavic has a vision system that can track people (and animals apparently). Based on the teaser video, I like the compactness of the Mavic and its controller. It’s not pocketable, but it looks like it could fit into an existing bag and not requires a special carrying case like the Karma. I think another big selling point will be DJI’s experience with drones compared to GoPro’s late entry into the crowded market. Take a look at the review from TechCrunch:
I think overall I would pick the Mavic over the Karma. The features, extra compactness and DJI backing make the price increase worth it. I guess this means that my bank account will be $1k lighter in the near future.
Another day and another release from the React team. React v15.3.2 looks mostly to be performance improvements and bug fixes. This is pretty similar to the v15.3.1 release. Nothing game-changing but I do appreciate somewhat frequent updates (about a month apart). Full list of updates/fixes are:
