WEBVTT 00:01.590 --> 00:02.270 Hi. 00:02.520 --> 00:10.230 In this section we'll be talking about React Native and I will explain why I picked React Native for 00:10.230 --> 00:15.830 our development, for our mobile application and why it might be useful. 00:15.840 --> 00:21.480 The first reason why react native, not the other solution we might have. 00:21.510 --> 00:23.300 It's a cross-platform. 00:23.310 --> 00:24.180 What does it mean? 00:24.360 --> 00:25.230 Cross-platform? 00:25.230 --> 00:30.480 That means you can write one code and it will compile into both Android and iOS. 00:30.510 --> 00:34.890 That's very convenient, but it's not the only framework that does that. 00:34.920 --> 00:42.810 You have other frameworks like Nativescript, you have Cordova and other Solution, and the reason I 00:42.810 --> 00:51.180 picked React Native is because we already know react and once we know react, we are kind of prepared 00:51.180 --> 00:53.430 to do React Native. 00:53.460 --> 01:00.960 It's very similar what we've done before and in fact it's still our react that we know so many things 01:01.060 --> 01:05.140 will be exactly the same as we've done before with our web application. 01:05.350 --> 01:07.330 So it's not going to be that different. 01:07.360 --> 01:09.640 React has another advantage. 01:09.640 --> 01:12.580 It will compile into fully native application. 01:12.580 --> 01:18.160 It's not like, for example, Phonegap Cordova application that will be Webview based. 01:18.160 --> 01:20.860 So it's a technology is based on the webview. 01:20.890 --> 01:23.890 That means it is a native application. 01:23.890 --> 01:29.860 And inside native application you have embedded web page, which is kind of very bad performance. 01:29.860 --> 01:32.500 It's much slower than the native solution. 01:32.500 --> 01:37.510 So React Native will compile into a native code. 01:37.510 --> 01:45.250 That means you write a JavaScript and that JavaScript will be compiled and prepared a fully native application. 01:45.250 --> 01:50.710 And that's very convenient because you write the language, you know, and you don't need to write two 01:50.710 --> 01:53.650 separate application for both platforms. 01:53.800 --> 01:56.080 So that's being said. 01:56.170 --> 02:03.040 We can take a look at the moment we are on the GitHub, IO React Native and if we will take a closer 02:03.040 --> 02:08.290 look at the URL here, you can see that's actually domain from Facebook. 02:08.530 --> 02:12.550 Facebook creates both react and react native. 02:12.580 --> 02:20.470 So having Facebook backed up on this project, we can be sure that it's not going to go anywhere soon. 02:20.470 --> 02:24.520 So there will be a developed and maintained very well. 02:24.520 --> 02:28.030 And actually, if you will go here, who is using React Native? 02:28.060 --> 02:30.250 You can see a big branch here. 02:30.250 --> 02:35.140 So obviously the Facebook application is using React Native. 02:35.170 --> 02:38.350 So whatever I do in the Facebook, you can do it as well. 02:38.350 --> 02:42.580 You have other things like Instagram, Pinterest, Skype and so on. 02:42.580 --> 02:50.830 So the list is huge and it's actually you will see a very powerful and very famous application that 02:50.830 --> 02:52.630 millions of users using that. 02:52.630 --> 02:57.340 And if they can do it in React Native, that means almost everything is possible. 02:57.610 --> 03:05.080 So coming back here and then we can take a look at at the few features, what we actually have. 03:05.110 --> 03:11.560 So as I mentioned before, we can actually write one code and we can have it on both platforms and then 03:11.560 --> 03:15.250 we can use our JavaScript or TypeScript if you prefer. 03:15.250 --> 03:24.120 So you will write JavaScript and it will compile into native and that's very easy to use and it's a 03:24.130 --> 03:27.010 cross-platform, as I also mentioned before. 03:27.520 --> 03:31.060 And then we will have a fast refresh. 03:31.060 --> 03:38.650 Once we'll start working with React, then we will be able to see our application running over either 03:38.680 --> 03:43.030 on your own mobile device or in an emulator or simulator. 03:43.030 --> 03:50.080 And I will show you all the different possibilities we have and you can pick which one is the best for 03:50.080 --> 03:50.410 you. 03:50.410 --> 03:54.430 So as I mentioned, this is Facebook supported and it's community driven. 03:54.430 --> 04:04.480 So at this point it's mature enough to have a production ready application with React Native because 04:04.480 --> 04:07.870 it's on the market for many years at the moment. 04:07.870 --> 04:16.720 So there is no risk of investing your time to learn something that might go off the market very soon. 04:16.720 --> 04:19.180 So I think it's a solid investment. 04:19.210 --> 04:27.190 Your time in and React Native is very powerful framework that will help us create application mobile 04:27.190 --> 04:31.060 application on both platforms, Android and iOS. 04:31.060 --> 04:35.110 And I will show you how we can start with React Native in the next video.
