0:00 Here we are in the GitHub repo, and let's just start where I recommended you start. Let's go up here and clone it.
0:09 Notice down here, we now have a code 00 starter app, and there's gonna be more 01, this feature, 02, that feature, and so on.
0:18 But down here, it even comes with instructions on what to do, so this is what we're gonna talk through,
0:23 but it's also written down right here in the readme. Step number one, we're gonna go and clone it. Now, I'm just gonna clone it to the desktop for now
0:31 so you can see what's happening, then I'll move it somewhere else later that you don't need to worry about. Also, I have a non-default terminal.
0:40 This one is warp, and I recommend you check out warp if you're on Mac or Linux. Maybe later, they said they're working on a Windows version,
0:49 but it's not out yet. So sometimes people ask me, Michael, what is this weird terminal thing you've got going on? That's what it is.
0:55 So we're on the desktop. We'll just git clone, and we'll just put in the URL. You don't need the .git, by the way.
1:01 You can have it, but it's not required. And here it is over on the desktop. It'll be called audio something or other.
1:11 So you can see we've got our readme. That's just not, that's not the one I was talking about. That just talks about the overall project.
1:20 We go into code, and we'll have the starter app here. And then this is the place that we're gonna be working. So for each one of these, we've got,
1:30 I'll open it up in Finder here for you. Each one of these has kind of got this top-level point-in-time name, so starter app, finished with transcripts,
1:42 or whatever we end up calling these. And it's got the node modules, and the source, and the requirements. So I recommend that you open up this folder,
1:50 or whatever section of the course, or point-in-time you wanna work with, into your editor. And because of that, I'm over here,
2:00 and we're gonna do a couple of things. First of all, notice there's no virtual environment. It does show there's this global one,
2:07 but I run with a virtual environment active all the time on my computer in case I wanna blow it away. It doesn't mess with System Python.
2:15 So what I'm gonna do is I'm gonna create a virtual environment. That's the first thing that we wanna do because you can see we have some requirements.
2:22 In fact, quite a few that we're gonna need for this app to run, and that's just a good practice. So we will say Python -m venv, venv.
2:31 Now, that would be fine, but I would like, see how this one is named global, not just venv. We can say --prompt.
2:40 And when that creates this virtual environment, the name is going to be just venv. But when we activate it, so this varies
2:53 depending on your operating system also laid out in that readme right here. On macOS and Linux, you say dot for apply to this shell.
3:02 Then you say venv/bin/activate, like so. Notice how it's 00starterapp, so it tells me which one it's in.
3:13 If I was on Windows, I would do venv scripts/activate.bat, why, oh why, for all that is right, do these have to be named separately?
3:24 I don't know, but that's the way it is. So that's one of the weird differences between Python on Windows and Mac, so we gotta do this.
3:32 Next, we need to get those requirements. I use piptools, and piptools takes this file, which is just the top-level unspecified requirements,
3:44 and compiles it, something like compiles it to, this more specific version. So what we're gonna do is, you don't need to use piptools,
3:54 you can just simply go here and pip install the requirements, but if you wanna mess with that and upgrade it, you're welcome to.
4:00 So I'll say pip install-r requirements.txt, virtual environment active, and as always, Python is always, always,
4:13 almost always, except for one or two weeks a year, out of date with its pip, so I actually have a thing that normally creates virtual environments
4:21 and automatically upgrades it, but it's not required, but go ahead and upgrade it, just so it doesn't complain to you. Okay, and there we have it.
4:29 We've got our virtual environment created, we've got it activated, the things we need to run the app are here.
4:37 So we could come over here and just say Python main and run our app, but at this point, I kinda wanna put the terminal and the shell down
4:44 and go over to a proper editor. So this folder is what I want to be the base, so in PyCharm on macOS, macOS only, you can do this, drag and drop it,
4:56 and it will open up this project. On Windows, you have to say file open directory and browse to it, not a huge deal, but that's how it works.
5:06 All right, here we have it in our program, and notice, got our source files down here, this is where all the code that we're working with.
5:15 One more thing we have to do before we're able to run this is we need to set things like the assembly AI API key.
5:23 Should that stuff be committed to Git? No, no, no, no, no, no, no, no, it should not. So what I've done here is I've created this settings file
5:35 that has a template default values for just local host server, but then here's where your API key goes. So what we're gonna do is we'll talk later
5:46 about the API key, but in order for the app to run, it just expects this file to be there, and later we'll go and enter our key in there.
5:52 If you already got it, go ahead and put it. Don't put it into this template. The goal is do what the action says, make a copy, save it to settings,
6:00 and in here put, and this is no longer needed, and put my API key. I'm gonna put my API key there, but you know what?
6:12 I'm not gonna share it with everyone because that one's mine, you put yours there. So with all of that in place, we should be able to run this,
6:20 although without MongoDB being here yet, it won't really work, so that's one more thing I'm gonna do before we actually go and run this code.
