A

Hi everyone in this video, what we're going to do is we're going to give it a try to the news. Soft web api services.

A

So if you have installed a new version of uh sap or basically devexpress engineer know when you check the what's new section and if you go to the sub part, you will end up here and here you can see the documentation on how to implement the api.

A

So the steps they tell you here like really simple in general, you don't have to do too much. The swagger like services are very wrong in the in the blazer application.

A

So the only thing that you need to do is that if you don't have a place or application, you need to watch, but if not, it will come already with it. So, let's create a new application.

B

The great thing about this is: we have been waiting for this for a while. It has been a lot of momentum to get to this point, and the exciting part is that we personally have struggled a lot doing all our service doing web pi service, doing graphql doing some crazy things, and now it comes out of the box and supported from the express. I know that is still in pre-release, but it's a lot promising and also we will be reusing all our data models that we're already having stuff we're gonna, be reusing our security system.

B

So this is this is amazing.

A

Yep and actually like, uh let me show you here: I will create both. So of course you just need a web application engineer, but I will do both xpo.

A

I will leave our communication standard in this case and for modules. Nothing. We don't need it's not listed as a module, let's just click on finish.

B

It's good to say that it comes already in the board with a template, but you can add it to an existing application. Only by reference, the norway, the express express sub web api and then adding the the extension method. Add software api with the options that you would show.

A

Yeah so basically yeah, let's go and check the predictor. um I guess we were talking about this.

B

A

Yeah- and this is a pre-release- actually, the version number okay. So after like adding these two.

B

And also it's good to show us that the the project isn't that five. I know that is a given, but it's good to mention, because even the odata version of data that is a developer for net five.

A

Yeah so yeah a lot of these stock will not come with barcode compatibility, but who needs that so, okay, let's go and check the stock. That is the place where the magic happens. So here you have the swire and also let's find out, because I think I I didn't see it so.

A

B

A

So for you guys so basically here you just need to register your types, I'm going to create a domain right now and then like basically, I will just not create this, so you can see how.

B

But if you can see also in the line below that one, we have a data extension method, pretty much. It will map the route of api or data. So that's where this, your your swagger will be leaving.

A

Yeah, well, you can also change this.

A

Url so the most simple scenario, um basically less properties.

A

A

Xps code and xps, okay, so far so good. We have the model and.

A

You can see the api's.

A

And then we will check this file here.

B

I think there is a good thing actually that you have to register every entity that way you would not expose your whole or aim by mistake. So.

A

You need to just want one basically or something like really simple.

B

A

So for integration, I think this is like super cool, because, okay, we are really spoiled with stuff. You don't have to create a ui.

B

And now you don't have to create the api, so you.

A

Don't have to create.

B

The ui, you don't have to create the database, and now you don't have to create the apis.

A

Yeah so we're getting like, we will be out of work. So, okay, we have domain of the one. uh It's going to be active. The date is going to be set for today. 01.

A

And if I go and click in the documentation, you can just click here. Okay, here I have this recommendation.

B

And from that thing is like, we can see that there is no domain object, one, yet it hasn't been still registered. So we have to do that to be able to show here.

A

Yeah, that's what I wanted to show that uh I mean. Is there already running, but there is nothing exposed, so you cannot. I mean you cannot tell okay like um this thing is like unsecured, it's mostly nothing!

A

So, okay! uh Here we need to copy this and register a few types. I guess we can use domain of big one.

A

But I think it would be also good to, uh of course, it is needed.

B

The application.

A

Motion user. Yes,.

A

Okay, so we have these two types and it's just from.

A

This other page, so we don't care that much about applications.

A

And now, let's refresh this file implementation so see now you have application user, that's one of the times that we registered, and you have also the main article and if you want to get there, for example, we know that we have to make it one distance.

A

You can try out this out and execute and yeah see here is where you have the results. So this is the id the active property, the date, the code and the name. So basically, this is like entire google api. um Okay. So that's basically what you need to do to uh um to expose types, because the the api is already running, at least in the news version of that.

B

So what about authentication.

A

Yeah, that's what I was going to do next, it's like! um Well, it tells you that you can use like any normal type of authentication. So let's come here and see.

A

So well, here is the authentication part in general. You can use any authentication that you can use with any mdc controller or calculator and dotnet, but if they tell you how you should include authentication, this is not for starting generally for any uh asp.net core application, um so they have an example here on how to hook up the authentication with with the all out authentication.

A

So in this case I mean there's a little more steps involved, but uh to not do like all the steps here, because it's like still a ctp, we can open the uh so in here. Basically, you will see that everything is the same as the other application. If you go to startup, the main difference is that there are more types and so so far so good, and if you remember the api that we exposed.

A

It doesn't show any parameters to authenticate. So let's open that again.

A

Let's see is the last one, this one, so you will see there is no logging method here, because it's not I mean you have to create it. At least at the moment. You have to make some code for that. So, if you go to the main, then this one.

A

If you go to main demo, you see, okay, you have more types here, and also there is this npc controller, so in this embassy, basically, they handle is an example of how to handle the login uh mechanism, and with this you can authenticate in the api and basically include any information that you want in the payload and send it back to the client, and with that token, you can basically interact with the api. So, for example, let's from this again.

B

And it's a really nice implementation using uwd dublin it also. It actually takes care of all your claims and not only that if you are not authenticated, it changes to the logging of staff, so it really has a really. They did a good implementation. Good ui, yeah, yeah.

A

And not only that um what I like the most is that it's using the latest and the greatest bits, and you get it in like one one or two lines of code and just to do this whole integration with game. If you do it like by hand, it will take maybe at least one day complete if you want to everything, keep so okay, let's log in and it's going to be, I'm.

B

Also going to use it because it's using open api, you can generate the clients with any all the tools that are out there.

A

So the url is the same because all the applications share the same user. So let's refresh this, and you will see that there is an authentication network. So if we want to try out these ones- and we um put the username sam, for example uh after you execute this see, it is discussing the controller so basically we're hitting the authentication and after this it just continues, and you will see this is the token. So, basically you can include this token in any other api course, and your api is secure and everything is like totally integrated.

A

Everyone is using the newest standards and the most beautiful thing of them all. You don't have to do almost anything. So there you go. You have like a free api in general.

A

There is a few things that I would like to include here and is to interact with the application model, so you can basically update the nodes of the application. Maybe we have we'll have to wait for that and you'll be good. So far so cool I mean this is just amazing, and the thing is that you don't have to do it like that. Much just registering the times, that's basically what you have to do.

B

It already comes in the template, so this is this is amazing, and not only that, because he's using odata, you can take advantage of all the operators that I have select filter order by and so on. So on so on, uh because this is an open api, you can use any of the tools out there to generate the client. This is inspired. You have this really nice ui interface, to test your api.

B

You also have a logging that is using soft security, so authorization with uwd tokens or any of the asp.net core authentication methods that we have in there. So a kudos to the the express thing, one thing that the documentation say is like lowering the grade the performance a little bit. We will have to test that a bit more, but so far. I think that this is looking amazing.

A

Before we want to.

B

A

Here there are a lot of services like this. I just needed to make a client like last week and I use this service. So in this service you can download the square recognition, because if you are running this api, you can go to the top, and here is the link for the definition. Like the schema of your api. You can download that save it or just expose it somewhere, and then you can go to a service like this one and basically generate a client.

A

So here, for example, I have this client and once you have it, you can go here here and I think you can just go in. Actually you can generate a client in any language, so you click export.

A

You create a client sdk and you can generate a client from the staff application from c-sharp go java, php python, scala, swift,.

B

A

You name it you have it so this is like the ultimate interoperability integration that you can do itself. It's like everything is supposed to http, so it's almost so cool to run, but your own logic on the main objects.

A

So that's it for this video.

B

Okay, so soft those photos, the ui the database and now the api, if they do my clients, business logic, uh yeah.

A

That would be important, yeah, absolutely.

B

Okay, guys thank you for sticking with us to lens and see you in the next video bye.
