00:00:00,910 --> 00:00:08,200

I just want to take a moment to go over why this site, wider application wide config is so useful right



2

00:00:08,200 --> 00:00:08,400

now.



3

00:00:08,410 --> 00:00:12,420

We only have two values in their use, cash and template cash.



4

00:00:12,850 --> 00:00:14,600

But I can add something to this.



5

00:00:14,620 --> 00:00:19,850

For example, let's add let's add a logger, and we're not going to do anything with it right now.



6

00:00:19,870 --> 00:00:23,170

We will when we get to improved air handling.



7

00:00:23,380 --> 00:00:31,510

But if I add a single member to this and I want to call it info log, and if a log is just going to



8

00:00:31,510 --> 00:00:38,560

be a a member on this app config struct, that allows me to write information to a log file and we're



9

00:00:38,560 --> 00:00:39,940

not going to do anything with it for a while.



10

00:00:39,940 --> 00:00:46,000

But I can add it just by saying I want to add a pointer to log logger, which is something built into



11

00:00:46,000 --> 00:00:50,980

the standard library that writes to log files or writes to the terminal or writes wherever we tell it.



12

00:00:50,980 --> 00:00:54,130

To write, we can write it to a file, we can read it to the terminal window.



13

00:00:54,400 --> 00:00:56,600

We can even write it to the database if we wanted to.



14

00:00:57,010 --> 00:00:58,740

Once we have the database set up, of course.



15

00:00:59,110 --> 00:01:00,280

So I've added that.



16

00:01:00,280 --> 00:01:06,220

And now just by the very fact that it's been added to this, the struct this app config struct, it's



17

00:01:06,220 --> 00:01:12,970

available to every part of my application that has access to the app config and that is incredibly useful.



18

00:01:13,480 --> 00:01:15,070

So I'm going to leave that in there for right now.



19

00:01:15,070 --> 00:01:19,780

We won't do anything with it for quite a while until we get to the centralized error handling part of



20

00:01:19,780 --> 00:01:20,590

our our course.



21

00:01:21,070 --> 00:01:22,270

But there it is.



22

00:01:22,360 --> 00:01:28,210

And that's one of the things that makes this site wide app config app configuration so useful.
