1

00:00:01,350 --> 00:00:06,930

So let's think about what we're going to build as the first project in this course, and it's always



2

00:00:06,930 --> 00:00:10,650

good to have a sense of what you want to do before you actually start working.



3

00:00:11,280 --> 00:00:14,870

Otherwise, you just kind of make it up as you go along and that rarely turns out well.



4

00:00:15,210 --> 00:00:20,490

So just in general terms, let's think about what kind of project we will build that will allow us to



5

00:00:20,910 --> 00:00:28,350

learn some important techniques and methodology in the go language and what our actual Web application



6

00:00:28,350 --> 00:00:28,650

will be.



7

00:00:28,650 --> 00:00:30,900

And we are going to build a Web application.



8

00:00:31,380 --> 00:00:37,080

So we, first of all, need to decide what we're going to build, have an overall sense of the project's



9

00:00:37,080 --> 00:00:42,510

scope, what's going to be included in the project and what key functionality has to exist.



10

00:00:43,020 --> 00:00:49,080

And what I want to do is I want to pretend that we own a bed and breakfast and that bed and breakfast



11

00:00:49,080 --> 00:00:52,660

has two rooms and we want to rent those out to people online.



12

00:00:53,280 --> 00:00:55,320

So we're going to have a bed and breakfast.



13

00:00:55,320 --> 00:00:56,400

It's going to have two rooms.



14

00:00:56,400 --> 00:01:01,860

And people should be able to come to a website, look at what's available, search for certain dates



15

00:01:01,860 --> 00:01:06,260

that they might want to stay with us and then make a booking and reservation.



16

00:01:07,470 --> 00:01:08,220

How do we do that?



17

00:01:08,250 --> 00:01:09,430

Well, what are we going to need to do?



18

00:01:09,480 --> 00:01:12,960

We're going to, first of all, have to have a Web site that showcases the property.



19

00:01:13,230 --> 00:01:20,310

So we'll go through the procedure of building templates and go and populating that with information



20

00:01:20,310 --> 00:01:25,590

that shows all the wonderful features that our bed and breakfast has and why people should choose to



21

00:01:25,590 --> 00:01:26,010

stay there.



22

00:01:26,790 --> 00:01:30,750

We also need to allow people to book a room for one or more nights.



23

00:01:30,780 --> 00:01:35,790

That means they have to come to the site, choose what room they might want to stay in, and then search



24

00:01:35,790 --> 00:01:39,360

to say, hey, I want to stay here from July the 6th to July the 10th.



25

00:01:39,720 --> 00:01:41,160

Is the room available?



26

00:01:41,160 --> 00:01:46,350

And we have to decide if that room has already been booked by somebody else and if it has to say sorry,



27

00:01:46,350 --> 00:01:50,760

those dates aren't available, would you like to try different ones or say, sure, the room is available,



28

00:01:50,760 --> 00:01:51,600

would you like to book it?



29

00:01:52,200 --> 00:01:57,300

And if the room is available, the guest should be able to enter some information and have information



30

00:01:57,300 --> 00:02:01,560

that the host knows what to prepare for when the person arrives or the people arrive.



31

00:02:02,160 --> 00:02:07,530

And then we need to notify the guests that their reservation was successful either by sending them an



32

00:02:07,530 --> 00:02:09,120

email or a text or whatever.



33

00:02:09,390 --> 00:02:13,050

And we also need to notify the property owner, hey, you got a new reservation.



34

00:02:13,050 --> 00:02:16,740

You might want to pay attention to it and make sure that things are ready before the guest arrives.



35

00:02:16,950 --> 00:02:22,200

OK, that seems like reasonable, unreasonable assumptions, key functionality.



36

00:02:22,200 --> 00:02:28,200

In addition to allowing someone to book a room, we need to have a kind of back end system that the



37

00:02:28,200 --> 00:02:33,570

owner of the bed and breakfast logs into to see who's coming and when they're coming, they need to



38

00:02:33,570 --> 00:02:35,700

be able to review existing reservations.



39

00:02:36,480 --> 00:02:41,700

We should probably show a calendar of their upcoming reservations and past reservations.



40

00:02:42,390 --> 00:02:46,950

They should be able to change or cancel the booking because, you know, people's plans change and someone



41

00:02:46,950 --> 00:02:50,850

might say, oh, we're going to stay for an extra day or no, we can't come at all, whatever it may



42

00:02:50,850 --> 00:02:51,140

be.



43

00:02:51,480 --> 00:02:53,850

So these are the kinds of things that we need to do.



44

00:02:54,210 --> 00:02:58,950

Now, this only takes a couple of minutes to go over in general terms, but there's a lot of work to



45

00:02:58,950 --> 00:02:59,700

make this happen.



46

00:02:59,700 --> 00:03:02,730

And it doesn't matter if you're building the program and go or are you doing it in.



47

00:03:02,730 --> 00:03:03,570

No, Jess.



48

00:03:03,580 --> 00:03:08,520

Or or whatever it may be, there's a lot of functionality that we need to think about.



49

00:03:08,970 --> 00:03:12,790

So to make this happen, what kinds of things are we going to need?



50

00:03:13,470 --> 00:03:16,380

Well, obviously, we're going to have to have some kind of authentication system.



51

00:03:16,380 --> 00:03:23,220

We want the owner to be the only person that can go in and change a booking or look at bookings and



52

00:03:23,220 --> 00:03:24,210

get this information.



53

00:03:24,450 --> 00:03:29,370

So it has to be a secured with a password or some means of logging into a backend system.



54

00:03:29,370 --> 00:03:31,080

So we're going to have to have authentication.



55

00:03:31,740 --> 00:03:34,890

We're also going to have to somewhere have somewhere to store this information.



56

00:03:35,520 --> 00:03:36,750

Where are the bookings go?



57

00:03:36,930 --> 00:03:39,480

What about users that can log into the back system?



58

00:03:39,480 --> 00:03:40,920

This has to be stored somewhere.



59

00:03:41,220 --> 00:03:45,030

So clearly a database seems like the obvious place to store this information.



60

00:03:45,630 --> 00:03:49,080

And we also need some means of sending notifications around.



61

00:03:49,170 --> 00:03:53,850

We need to be able to send an email or send an SMS message, a text or both.



62

00:03:54,180 --> 00:03:57,780

So we need to think about how we're going to implement these things.



63

00:03:58,260 --> 00:04:00,570

And it's a fair bit of work, but it's kind of fun.



64

00:04:00,570 --> 00:04:07,230

And we're going to go through and build a fully functional system that allows people to book reservations



65

00:04:07,230 --> 00:04:07,830

online.
