I'm Jesse.

And with me is Gemma Ambrose in the background.

And Cordelia, you say Eiko?

Delia, how would you?

All right, so anyway, my kids, they're all here.

Well, not all of them is another one.

Upstairs have four.

But today we're gonna continue to work on this Expo React.

Native app.

Uh, so right now we're running it as a, um, as a Web app.

So, uh, Evan Bacon's in the channel who works at Expo and awesome.

Awesome stuff with Expo Web.

We are going to see some extra web stuff.

That's let me bring this up on the screen.

Ah, let's see where it went.

What a shame.

Look, there you go.

My computer went into sleep mode.

Ah, and so Oh, my Oh, my screens get rearranged.

I had it all set up, and then I lost it.

There we go.

All right, So this is the ab running.

Actually, it's not.

It's not really running.

Uh, it's just whatever's left over from what we ran last last evening.

What do you hold?

Enough?

Amber, make a side.

Uh, hey, what is not a Gatorade commercial?

All right.

So anyway, I'm running, react native with Expo and see if the chat something's up with my chat.

If, um, somebody tried to type something in the chat because I think my check that disconnected.

And I'll see if I can see it.

Because right now I am not able to see the messages in the chat.

I could try toe open it in a new window.

Okay?

I opened my chat in a new window, and now I can see the messages, so hopefully this will work.

Okay?

Yes.

So I think I lost some of the first messages.

So if he asked me something right off the bat, then I probably can't see it anymore.

But I can see the chat now.

So, everybody, it was really weird.

There were only, like, three messages in the chat, and that's very uncommon.

So I I just lost the first few messages or whatever s.

Oh, sorry about that.

But, uh, Anyway, um, I am I built this, uh, like built apple with Expo, which is a tool that helps you build with react native eso I'm using your in.

So I just typed in your own start and now once Expo runs and does its thing.

If I hit W, it'll open up the expo app in a Web browser.

Eso you could see here having the Web browser reckon.

Refresh.

It's it's running here, which is pretty sweet, and it actually makes it way easier.

Cardio.

You don't hit that button.

You can't sit with me.

All right, 1,000,000 buttons.

Uh, I'll sit with you.

So it's actually really awesome.

I kind of prefer working like this unless there's something I really need to test on a mobile phone.

I prefer to do most of the development with the Web, UH, version of of Expo, which is using React.

Native Web.

It's just so much easier to be able to do all your bugging with, um, like in a Web right.

The the feedback loop is tighter.

Alright, so there's less time, you know, the there's a little bit of lag if you're developing, like on a mobile device that connected your computer between when you make a change and what it actually updates on the device, I find like, uh, I just have way less issues doing it like this.

I do have to frequently kind of keep the mobile version open, though, just to make sure I haven't messed anything up.

But it definitely helps me develop faster.

This'd is I've used this professionally and on side projects like I'm doing here.

So, uh, definitely I like that.

That aspect of it do it and trying to get my here we go get my chat.

Oh, uh, situated with the stream data on my other screen here.

Okay, cool.

So this is the third stream that we've done with this particular app.

Uh, real quick.

I'm gonna go over the goal of this app.

We are trying to take data from a brain computer interface, which I'll put on in just a minute and I'll show you.

But there's a company called Know Ross Iti.

That makes a brain computer interface.

That's called the notion It's it.

I read your brain waves and then it has a new interface Java script interface that you can use to get that data into your app.

So that's what we're going to do.

And for this particular app for phase one of the app, all I want to do is measure my level of focus and then display a warning whenever my focus is dropped too low just to kind of remind me to stay focused on what you put in your mouth.

What is that?

Gift card?

All right, so that's the goal.

Now, in this particular stream, what we want to do is we pretty much did most of the work we needed to persist.

User data from one session to another, Uh, and we want to keep basically wanted just, Ah, finish that.

We're almost finished.

We had kind of a little bug with it at the end.

So when you finish that and then I actually put in our threshold for the the focus.

So, like, we're gonna figure out, like at what level of focus should be Sure.

Warning.

And what should that warning on?

And it's probably gonna be a different warning on the web as opposed to on on Mobile.

Hey, kid, you can all sit on my lap, so why don't you go play?

Uh, that's for, uh, camera.

Oh, yeah.

Don't press these buttons.

It links up to my phone via Bluetooth.

But if you're gonna be down here, you can't interrupt me.

Okay?

Uh, so All right.

Let's see.

So here's how we're gonna do this in the stream.

I'm gonna start a timer.

A Pomodoro timer.

It's gonna go for 25 minutes during that time that 25 minutes.

I'm not really gonna look at the chat too much.

I try to focus on coding and explaining what I'm coating.

And then after the timer goes up, I'm gonna take a break.

I'm gonna go to the chat, and I'm gonna answer all your questions.

I want to try to keep this stream to just about an hour long on because I wanna try to get the kids to bed, help get the kids to bed.

So you want to say something?

Jimmy would like to say.

So why not get the Corona virus?

Yeah, it's very good.

Yeah.

Gemma.

Gemma.

What doesn't want anyone to get the Corona virus?

Be safe.

You want to say something to everybody?

Gets to say one thing and then you gotta let me coat.

All right?

L don't.

Jemma says don't get the current of Iris immerses.

Don't die.

Cornelia.

Would you like to say anything?

She could do?

Twirls all by herself.

All right, All right.

Now you already chairs to say something.

Now you gotta be quiet.

Let me do the Cody.

Okay.

A lot of people want to see the coding part.

Okay.

What?

Gemma, when you get older, you can have a YouTube general, too.

Right on, Actually.

So Gemma has been working on free code camp lessons to learn how to code.

And Ambrose has been working on coding, too.

Kindergarten math.

Yes.

I told him he had to learn how to read, and he had to learn his mask.

Um, all right, so see you later, date.

Should being on the show are seeing about seeing about now would be good.

Okay.

All right.

So anyway, uh, hope Hope you're all right with that.

That's how it is when you, uh um you work with kids.

I don't really have an office of just in my basement, so the kids can just come down whenever.

Ah, so let's get started.

I'm gonna start my timer, make sure it's actually working on yesterday's show.

I started the timer, and then somehow I stopped it.

And, um uh, so it looks like it's running successfully this time.

All right, Cool.

Let me make this bigger make sure everybody can see.

All right, I'm gonna make this a smallest.

I can.

I'm gonna get rid of these files on the side.

I did put this on Getem.

Eso If you check the description for this video, there's a link to the ghetto grip.

Oh, so you can see all this code.

And, um, I guess it's not gonna be that useful to you unless you have a notion headset.

But you get least check out, see what we're doing.

Um, get a kind of a closer look at the code.

But what we want to do is the next step, I guess we want to do, is look, the user can put in their i d e mail and password and that links them up to the brain computer interface, and it gets us data.

But as soon as we refresh the page, they lose their, um, their subscription to the device as soon as you put the idea and we can get it again.

But what I want to do is save the I d in local storage so that they don't even have to put the idea in again.

And we just check local storage eso We already have the code for that in here.

So we have this, um, this get item for and we're going to get the device.

I d right.

But the problem is with the part where we actually save is not working right now, So we want to figure out where we can make this save s o.

The reason it's not working is I I think I think that this function is actually running first and we're going to test that.

Let's test that because I don't think we really have.

I'm just gonna do a console log here and just console awesome some nonsense just to see if that is, in fact, what's happening and let's make suspect will bring up the console.

And ah, I want to see if that's really the issue that's happening here.

I'm not convinced that it is on.

Let me get my data.

Yep.

This is it, uh, you turn my device on.

So this is the no Rossi notion had set.

If you want to know more about this headset and how it works, you can go Thio.

You can check out a video I did on my YouTube channel.

Um, the link to my YouTube channels In the description below, I talk a lot more about what this headset conduce you and give you like a demo.

Uh, so all right, that's going to start up.

It's just gonna take a few seconds to start, and then we'll should be able to connect.

In the meantime, let me type in our data.

Okay, so this is actually running every time something changes, which is what I thought it was That was happening.

Eso What's gonna happen now is if I put a password in, this is gonna run, and I believe it's going to try to lock us in eso.

What I'm gonna do is let's just remove password from here, so this doesn't run.

When a password is entered, it's gonna erase my stuff.

But I'll just copy it again and let's verify.

Yeah, cease of password is not running here.

So is going to test my theory to see if it was actually this function that was logging us in, uh, early.

It was basically, we're getting log into early, like before we press the button and log in, which probably change that to log in instead of press meet.

But remember to do that.

Okay, so I grabbed a password.

All right, Sweet.

So it was dysfunction that was automatically logging us in s o just by removing password.

I think we've solved that issue.

And now when I hit this, this button should call this in it function, which should first save our device.

I d to a sink storage.

So let's go.

Let's go to our, uh, application and go to a local storage and see, right now, we don't have the device.

I d sage.

When I hit this button, the device and he should be saved.

And we should get logged in which?

Yep.

All right, so the notions online, I just wanted to double check.

So sweet.

So we have our device idea, and that was, uh, wait, this biggest I could see.

Uh, all right, so we could see we have our device.
