Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated: 1 00:00:01,280 --> 00:00:06,720 now another benefit of next.js is 2 00:00:04,080 --> 00:00:09,599 serverless functions 3 00:00:06,720 --> 00:00:10,880 remember when i call next.jsp fullstack 4 00:00:09,599 --> 00:00:12,480 framework 5 00:00:10,880 --> 00:00:14,960 this is why 6 00:00:12,480 --> 00:00:17,119 you can essentially run your node.js 7 00:00:14,960 --> 00:00:18,400 code in the same codebase as your 8 00:00:17,119 --> 00:00:20,880 reaccode 9 00:00:18,400 --> 00:00:21,920 and it all lives inside the pages 10 00:00:20,880 --> 00:00:24,640 directory 11 00:00:21,920 --> 00:00:26,560 now anything inside the api folder you 12 00:00:24,640 --> 00:00:29,199 will automatically 13 00:00:26,560 --> 00:00:31,119 route to it right it automatically a 14 00:00:29,199 --> 00:00:33,600 route is created for that because of the 15 00:00:31,119 --> 00:00:36,880 next year's file system based routing 16 00:00:33,600 --> 00:00:39,440 right but also anything under the api 17 00:00:36,880 --> 00:00:42,879 folder also has a node server configured 18 00:00:39,440 --> 00:00:44,719 already and it all comes out of the box 19 00:00:42,879 --> 00:00:47,200 what's really cool is that you can do 20 00:00:44,719 --> 00:00:49,200 all of this without any configuration 21 00:00:47,200 --> 00:00:51,280 and your front end can easily talk to 22 00:00:49,200 --> 00:00:54,239 your backend that is the serverless 23 00:00:51,280 --> 00:00:57,520 function so in an example here hello is 24 00:00:54,239 --> 00:01:01,039 actually a serverless function 25 00:00:57,520 --> 00:01:03,199 now what exactly is the advantage here 26 00:01:01,039 --> 00:01:05,680 why do we want to make sure that we want 27 00:01:03,199 --> 00:01:07,600 our front-end to talk to our back-end 28 00:01:05,680 --> 00:01:09,920 well let's take a look 29 00:01:07,600 --> 00:01:13,439 if you're trying to go ahead and call a 30 00:01:09,920 --> 00:01:15,439 foursquare api or an airtable api 31 00:01:13,439 --> 00:01:18,240 or any other api 32 00:01:15,439 --> 00:01:20,240 that has specific secret credentials 33 00:01:18,240 --> 00:01:21,439 that we don't want to share with anyone 34 00:01:20,240 --> 00:01:22,560 right 35 00:01:21,439 --> 00:01:25,119 you don't want to store those 36 00:01:22,560 --> 00:01:27,119 credentials on your client because any 37 00:01:25,119 --> 00:01:29,360 malicious user can go ahead and access 38 00:01:27,119 --> 00:01:32,479 it but instead you want to store those 39 00:01:29,360 --> 00:01:34,880 credentials on the server 40 00:01:32,479 --> 00:01:36,640 that api key should be on the server 41 00:01:34,880 --> 00:01:37,840 that you should be hiding from your end 42 00:01:36,640 --> 00:01:39,680 users 43 00:01:37,840 --> 00:01:41,280 and this is possible because of 44 00:01:39,680 --> 00:01:43,119 serverless functions 45 00:01:41,280 --> 00:01:45,520 the front end can easily talk to your 46 00:01:43,119 --> 00:01:48,960 backend and backend will be the place 47 00:01:45,520 --> 00:01:51,280 where you will call these specific apis 48 00:01:48,960 --> 00:01:53,280 but if you're wondering wait hold on a 49 00:01:51,280 --> 00:01:55,759 second now that we know all the 50 00:01:53,280 --> 00:01:57,600 capabilities of serverless function what 51 00:01:55,759 --> 00:01:59,920 exactly are they 52 00:01:57,600 --> 00:02:01,200 what does what do we mean by serverless 53 00:01:59,920 --> 00:02:03,360 functions 54 00:02:01,200 --> 00:02:04,479 well let's take a look at the diagram 55 00:02:03,360 --> 00:02:06,159 here 56 00:02:04,479 --> 00:02:08,560 as we make a request to a serverless 57 00:02:06,159 --> 00:02:10,720 function called as hello essentially 58 00:02:08,560 --> 00:02:12,720 what's going to happen is 59 00:02:10,720 --> 00:02:15,120 it is going to go ahead and spin up a 60 00:02:12,720 --> 00:02:18,239 new server just to make sure that it 61 00:02:15,120 --> 00:02:20,239 fulfills that specific request and after 62 00:02:18,239 --> 00:02:21,440 no activity it is going to go ahead and 63 00:02:20,239 --> 00:02:22,160 shut down 64 00:02:21,440 --> 00:02:25,520 so 65 00:02:22,160 --> 00:02:27,760 the minute we call slash api hello it is 66 00:02:25,520 --> 00:02:30,239 going to wake up the server start a 67 00:02:27,760 --> 00:02:33,680 brand new node server it is going to 68 00:02:30,239 --> 00:02:35,680 execute the code inside the hello api 69 00:02:33,680 --> 00:02:38,239 and then go ahead and 70 00:02:35,680 --> 00:02:41,280 execute it successfully 71 00:02:38,239 --> 00:02:43,840 and then shut down the server 72 00:02:41,280 --> 00:02:46,160 so this is why it is called a serverless 73 00:02:43,840 --> 00:02:48,480 function you only need the server to 74 00:02:46,160 --> 00:02:50,319 perform that specific task and if there 75 00:02:48,480 --> 00:02:52,480 is no activity it is going to go ahead 76 00:02:50,319 --> 00:02:54,959 and shut it down 77 00:02:52,480 --> 00:02:56,080 so this is the power of serverless 78 00:02:54,959 --> 00:02:58,640 functions 79 00:02:56,080 --> 00:03:01,200 and all of this is already configured in 80 00:02:58,640 --> 00:03:03,760 xjs you don't need to do any additional 81 00:03:01,200 --> 00:03:06,000 setup for it all we need to do is go 82 00:03:03,760 --> 00:03:07,599 ahead and create a new file under the 83 00:03:06,000 --> 00:03:10,239 api folder 84 00:03:07,599 --> 00:03:11,680 serverless functions are really powerful 85 00:03:10,239 --> 00:03:13,920 because you don't need to keep your 86 00:03:11,680 --> 00:03:16,080 server running all the time 87 00:03:13,920 --> 00:03:19,200 and to learn more about serverless 88 00:03:16,080 --> 00:03:20,879 functions because there is a lot you 89 00:03:19,200 --> 00:03:22,239 have to check out the course and learn 90 00:03:20,879 --> 00:03:24,159 more about the serverless functions 91 00:03:22,239 --> 00:03:26,319 there we will be using serverless 92 00:03:24,159 --> 00:03:28,799 functions throughout this course and 93 00:03:26,319 --> 00:03:30,799 diving into all the nitty-gritty details 94 00:03:28,799 --> 00:03:32,640 about serverless functions and i'm 95 00:03:30,799 --> 00:03:34,879 really excited for that because they are 96 00:03:32,640 --> 00:03:38,000 definitely my favorite 97 00:03:34,879 --> 00:03:40,720 so this is why next yes is known as the 98 00:03:38,000 --> 00:03:43,519 react framework for production because 99 00:03:40,720 --> 00:03:46,159 in order to make a production ready site 100 00:03:43,519 --> 00:03:49,200 you need to have all the necessary 101 00:03:46,159 --> 00:03:51,760 powerful tools to be able to do that 102 00:03:49,200 --> 00:03:54,640 and we won't just have any side we would 103 00:03:51,760 --> 00:03:57,599 have the best performance site out there 104 00:03:54,640 --> 00:04:00,080 and thanks to nexjs as we are able to go 105 00:03:57,599 --> 00:04:02,400 ahead and build front end as well as 106 00:04:00,080 --> 00:04:03,760 back end of your app in the same code 107 00:04:02,400 --> 00:04:07,599 base 108 00:04:03,760 --> 00:04:10,159 and also we get seo we get performance 109 00:04:07,599 --> 00:04:12,879 and we also get a lot of 110 00:04:10,159 --> 00:04:15,680 things that makes the life of developers 111 00:04:12,879 --> 00:04:18,639 so much easier 112 00:04:15,680 --> 00:04:21,359 all right so now that we have learned 113 00:04:18,639 --> 00:04:23,919 about serverless functions 114 00:04:21,359 --> 00:04:24,960 let's take a look at why nextgs is 115 00:04:23,919 --> 00:04:29,280 popular 116 00:04:24,960 --> 00:04:32,240 and if we have any doubts yet because 117 00:04:29,280 --> 00:04:35,800 we now know why it is popular right so 118 00:04:32,240 --> 00:04:35,800 let's take a look 8275
