API Project Tour

[00:00:00]
>> Scott Moss: Park the repo, pull it down. I'm gonna Go through. The complete version of it right now, it's not gonna work for you if you try to go to the complete version because you're gonna need like a database and environment variables and stuff like that So if you're gonna try to go through this complete version, cool, so just wanna give you a tour of the app. So 13 right now is the final solution and.

[00:00:14]
So 13 right now is the final solution and. Everything you see here, you're we're gonna do in this course. I don't think there is outside of these like configuration files, I don't think. I don't think I'm did anything for you.

[00:00:30]
I don't think I'm did anything for you. You'll be doing most of this stuff from scratch, so there gonna be a lot of stuff we're gonna be doing, but just give you a high level, We're gonna be talking about controllers, databases, middleware, routes, things like that, and, you know, just to run this, let me make sure I have. My database set up, I do. It's gonna Go ahead and you know.

[00:00:47]
It's gonna Go ahead and you know. On dev. Cool, so I'll have a server running on 3000. I'm gonna use a tool called Postman.

[00:01:04]
I'm gonna use a tool called Postman. Don't worry, we'll talk about this, In a second, but it's basically just a way for, it's a GUI for our API. It's how we can test our API. So, for instance, if I want to log into this API.

[00:01:17]
So, for instance, if I want to log into this API. I have an email and password for a user that I already seeded. I think it's already in this database. If not, I'll, we'll see in a second.

[00:01:31]
If not, I'll, we'll see in a second. Let me hit send here. And boom we got a successful log in so this is showing off our off this user logged in, we get a JSON Web Token so if you ever wonder about JSON Web Tokens we'll be covering stuff like that we can sign up, we could do all different types of stuff here so if I see like register I put like. Some other person, let's see.

[00:01:50]
Some other person, let's see. If that works, oh yeah, I need a username. I forgot I had that validation working. To One.

[00:02:08]
To One. Do that. What else? Password.

[00:02:24]
Password. Oh, at least 8 characters, come on. Killing me. At least I got get error messages and then boom, now signed up, got a user, everything's there.

[00:02:40]
At least I got get error messages and then boom, now signed up, got a user, everything's there. So this is essentially what we're gonna be building. We're gonna be using Postman to test our API. Well, not test because we're gonna write tests, but for us to interact with our API so we don't have to build a UI, in the future if you wanna like take this repo and build a GUI for it that's a great project to work on, but we won't be covering that, but yeah, this is essentially the app some more things I can show you that you're gonna be doing here is we have, for instance, if I run some of these tests right now.

[00:02:52]
Well, not test because we're gonna write tests, but for us to interact with our API so we don't have to build a UI, in the future if you wanna like take this repo and build a GUI for it that's a great project to work on, but we won't be covering that, but yeah, this is essentially the app some more things I can show you that you're gonna be doing here is we have, for instance, if I run some of these tests right now. No files found because why is that? Source tests. Tests.

[00:03:09]
Tests. Oh, that's right, they're in the. The solution branch. There you go.

[00:03:27]
There you go. So, now if we run some of these tests. Couple of things happening here. Is that gonna work?

[00:03:45]
Is that gonna work? OK, that did work. Bunch of tests here that we'll be running for essentially doing like integration tests just to make sure that like our routes do the thing they're supposed to do and respond with the. Status code they're supposed to respond with so you'll be writing pretty much all these tests here we have the ability to do things like.

[00:03:59]
Status code they're supposed to respond with so you'll be writing pretty much all these tests here we have the ability to do things like. Seed the DB, so if I wanted to. Put in some fake data. Into this DB I can do that.

[00:04:10]
Into this DB I can do that. This will allow us to have an API that's already ready to Go with some data that we can work with, which is great for something like Postman. If you don't have data it's really hard to like You know it's like when you're building a frontend app if you don't like hacks sometimes you gotta knock out the data so you can actually put the things on the screen, and you wanna see the database so you can actually, interact with it and figure out like, you know what the schema might be data model, different things like that so we have like a seed script.

[00:04:19]
So we're gonna cover all that, in this course, like I said, if you just try to do any stuff that I just tried to do, you probably won't be able to do it unless for some reason you just know how to set up databases and you did that already it's probably not gonna work because you need to set up an environment variable, but this is what we're gonna
