1 00:00:01,250 --> 00:00:03,810 ‫Before we can get started with this course, 2 00:00:03,810 --> 00:00:06,410 ‫we actually need to install Node.js 3 00:00:06,410 --> 00:00:09,020 ‫on our local development computer. 4 00:00:09,020 --> 00:00:12,270 ‫And this process is actually exactly the same 5 00:00:12,270 --> 00:00:14,370 ‫for all operation systems. 6 00:00:14,370 --> 00:00:17,210 ‫So in this video, I will use Mac OS, 7 00:00:17,210 --> 00:00:21,100 ‫but on Windows or Linux, it's really just the same. 8 00:00:21,100 --> 00:00:23,270 ‫Now installing other technologies 9 00:00:23,270 --> 00:00:25,250 ‫like the MongoDB database, 10 00:00:25,250 --> 00:00:27,290 ‫works very differently on Windows. 11 00:00:27,290 --> 00:00:30,120 ‫And so by then, I will have one video for Mac 12 00:00:30,120 --> 00:00:33,010 ‫and one for Windows, all right? 13 00:00:33,010 --> 00:00:36,683 ‫Anyway, let's now go add and install Node.js. 14 00:00:37,870 --> 00:00:42,210 ‫So in your web browser, head over to nodejs.org, 15 00:00:42,210 --> 00:00:45,310 ‫and then on the website, you should see these two 16 00:00:45,310 --> 00:00:48,440 ‫big green buttons here to download Node.js 17 00:00:48,440 --> 00:00:51,070 ‫for your current operating system. 18 00:00:51,070 --> 00:00:54,110 ‫So up here, you should see automatically selected 19 00:00:54,110 --> 00:00:56,570 ‫the OS that you're currently running. 20 00:00:56,570 --> 00:00:59,670 ‫And if not, you can just head over here to DOWNLOADS 21 00:00:59,670 --> 00:01:03,630 ‫and then select your operation system from there, okay? 22 00:01:03,630 --> 00:01:06,660 ‫Then here, you can select which Node.js version 23 00:01:06,660 --> 00:01:08,490 ‫you would like to install. 24 00:01:08,490 --> 00:01:13,120 ‫So, right now, the long term support version is version 10, 25 00:01:13,120 --> 00:01:14,520 ‫and so that's actually the one 26 00:01:14,520 --> 00:01:16,270 ‫that I'm using in this course. 27 00:01:16,270 --> 00:01:18,080 ‫But right now, the current version, 28 00:01:18,080 --> 00:01:21,410 ‫so the newest one basically, is 12, okay? 29 00:01:21,410 --> 00:01:23,950 ‫But Node just recommends for most users 30 00:01:23,950 --> 00:01:26,010 ‫the Long-Term Support version 31 00:01:26,010 --> 00:01:29,220 ‫and also by the time I started recording this course, 32 00:01:29,220 --> 00:01:31,950 ‫version 10 was actually the current one. 33 00:01:31,950 --> 00:01:35,400 ‫And so therefore, in this course, we're using version 10 34 00:01:35,400 --> 00:01:36,610 ‫and so you can go ahead 35 00:01:36,610 --> 00:01:39,930 ‫and download this version now as well, all right? 36 00:01:39,930 --> 00:01:42,690 ‫Now if you're watching this video in the far future, 37 00:01:42,690 --> 00:01:47,120 ‫then another version might already be here, the LTS version. 38 00:01:47,120 --> 00:01:50,640 ‫So let's actually take a look here at the schedule. 39 00:01:50,640 --> 00:01:53,550 ‫And so you see that they actually have a timeline here 40 00:01:53,550 --> 00:01:55,740 ‫for all the versions in the future. 41 00:01:55,740 --> 00:01:58,730 ‫So right now version 10 is the active version, 42 00:01:58,730 --> 00:02:02,950 ‫but if you're like watching this video for example in 2021, 43 00:02:02,950 --> 00:02:07,400 ‫well then you should probably go with Node.js 14, okay? 44 00:02:07,400 --> 00:02:09,540 ‫Now, what's also important to note here 45 00:02:09,540 --> 00:02:12,440 ‫is that you should only use the even version numbers 46 00:02:12,440 --> 00:02:14,530 ‫for a production project. 47 00:02:14,530 --> 00:02:19,530 ‫So that's 10, 11, 14, and so on and so forth. 48 00:02:20,600 --> 00:02:23,190 ‫And in case you're worrying that I'm using an old version 49 00:02:23,190 --> 00:02:25,790 ‫in this course, in case you're watching this 50 00:02:25,790 --> 00:02:28,050 ‫in the far future, then let me tell you 51 00:02:28,050 --> 00:02:30,520 ‫that Node actually doesn't change that much, 52 00:02:30,520 --> 00:02:33,230 ‫in terms of what we're gonna do here in this course, 53 00:02:33,230 --> 00:02:36,120 ‫from one version to the other, okay? 54 00:02:36,120 --> 00:02:38,120 ‫So probably, you will be perfectly fine 55 00:02:38,120 --> 00:02:41,030 ‫by using Node 12 or Node 14. 56 00:02:41,030 --> 00:02:45,110 ‫And everything will be working in the exact same way, okay? 57 00:02:45,110 --> 00:02:47,870 ‫And only in case you run in any problem, 58 00:02:47,870 --> 00:02:50,730 ‫you can then go ahead and install Node 10 59 00:02:50,730 --> 00:02:54,480 ‫and see if your problem disappears by doing that, okay? 60 00:02:54,480 --> 00:02:56,810 ‫So again, don't worry all too much 61 00:02:56,810 --> 00:02:59,250 ‫about outdated versions here. 62 00:02:59,250 --> 00:03:00,370 ‫All right? 63 00:03:00,370 --> 00:03:04,180 ‫Anyway, let's now actually download this version 10 here 64 00:03:04,180 --> 00:03:07,020 ‫so that I can take you here through the process. 65 00:03:07,020 --> 00:03:12,020 ‫So once that arrives, just open it, and then as always, 66 00:03:12,870 --> 00:03:15,420 ‫just click Continue everywhere. 67 00:03:15,420 --> 00:03:16,433 ‫You must agree. 68 00:03:19,450 --> 00:03:20,703 ‫And then install it. 69 00:03:22,960 --> 00:03:23,793 ‫Okay. 70 00:03:23,793 --> 00:03:26,740 ‫And with this, you should now have Node.js installed 71 00:03:26,740 --> 00:03:28,450 ‫on your local computer. 72 00:03:28,450 --> 00:03:31,513 ‫Now just to test it, let's close the window here. 73 00:03:33,070 --> 00:03:34,120 ‫All right. 74 00:03:34,120 --> 00:03:37,450 ‫And then open up your terminal, okay? 75 00:03:37,450 --> 00:03:40,970 ‫So, I'm using Terminal.app on Mac OS 76 00:03:40,970 --> 00:03:43,500 ‫and on Windows, you can use the Command Prompt 77 00:03:43,500 --> 00:03:44,800 ‫or the PowerShell. 78 00:03:44,800 --> 00:03:47,560 ‫Both work just fine, okay? 79 00:03:47,560 --> 00:03:50,790 ‫So in order to test if we have Node.js installed, 80 00:03:50,790 --> 00:03:55,570 ‫just write node and then -v, which stands for version. 81 00:03:55,570 --> 00:03:56,760 ‫Hit Return. 82 00:03:56,760 --> 00:03:59,320 ‫And so that should then give you the version number 83 00:03:59,320 --> 00:04:01,320 ‫of your current installation. 84 00:04:01,320 --> 00:04:04,910 ‫And in case you see an error here, then you should probably 85 00:04:04,910 --> 00:04:07,670 ‫try to reinstall Node.js. 86 00:04:07,670 --> 00:04:09,890 ‫Now, if you're taking this course, 87 00:04:09,890 --> 00:04:13,530 ‫I'm assuming that you're already familiar with the basic use 88 00:04:13,530 --> 00:04:16,130 ‫of the Terminal, or of the command line. 89 00:04:16,130 --> 00:04:19,600 ‫So you should know basic commands, like ls, 90 00:04:19,600 --> 00:04:23,360 ‫to take a look at all the files in a current directory. 91 00:04:23,360 --> 00:04:25,760 ‫On Windows, that's actually D-I-R, 92 00:04:25,760 --> 00:04:28,250 ‫so which stands for directory, and again, 93 00:04:28,250 --> 00:04:31,320 ‫that will give you a list of all the files or folders 94 00:04:31,320 --> 00:04:33,580 ‫in the current location, okay? 95 00:04:33,580 --> 00:04:35,970 ‫So in the Terminal, you're always in a location. 96 00:04:35,970 --> 00:04:38,690 ‫In my case, I'm currently in the Home folder. 97 00:04:38,690 --> 00:04:40,680 ‫And then you can basically move around 98 00:04:40,680 --> 00:04:42,300 ‫in your folder structure. 99 00:04:42,300 --> 00:04:45,170 ‫For example, if I wanted to move to my Desktop, 100 00:04:45,170 --> 00:04:50,170 ‫I could use cd Desktop, hit Return, 101 00:04:50,350 --> 00:04:52,030 ‫and now I'm in the Desktop. 102 00:04:52,030 --> 00:04:53,923 ‫Then I can go back with cd .., 103 00:04:55,310 --> 00:04:59,040 ‫and so now I'm back here in this main folder. 104 00:04:59,040 --> 00:05:01,280 ‫And actually, we don't need to know much more 105 00:05:01,280 --> 00:05:04,540 ‫about the Terminal or the command line, okay? 106 00:05:04,540 --> 00:05:08,010 ‫So we won't use much more than what I just showed you 107 00:05:08,010 --> 00:05:09,800 ‫in this two minutes. 108 00:05:09,800 --> 00:05:10,690 ‫Great. 109 00:05:10,690 --> 00:05:13,340 ‫So now that you have Node.js installed 110 00:05:13,340 --> 00:05:14,870 ‫on your development computer, 111 00:05:14,870 --> 00:05:16,500 ‫we are ready to move on. 112 00:05:16,500 --> 00:05:19,603 ‫And so I hope to see you soon in the next video.
