Let's highlight just some of the key technologies
0:02
that you're going to learn as we go through this course.
0:05
No surprise, we're going to focus mainly on Flask.
0:08
So you're going to learn all about Flask
0:10
some of it's main features as well as some of the things
0:14
that you don't see too often in a lot of tutorials
0:16
and other places, but I think are super, super important.
0:20
Flask is great for serving up content
0:22
but it doesn't help to make it pretty.
0:24
So we're going to use Bootstrap to make a theme
0:27
for our site that looks quite a bit better than
0:31
what we just get out of the box with pure HTML.
0:34
We're going to need a data backend
0:35
and we're going to use a relational database
0:37
for most of our site, and we're going to use SQLAlchemy
0:40
to talk to that database.
0:42
So, we're going to take it easy and make set up
0:45
and whatnot easy on you and use SQLite
0:47
which is built in to Python
0:49
and then SQLAlchemy to talk to SQLite.
0:52
But all you got to do is change the connection string
0:53
to talk to something like Postgres.
0:56
Many many sites run on relational databases
0:59
but some don't, so we're also going to take all the code
1:02
in a specially designed patterns that we build up
1:05
throughout this course.
1:07
We're going to convert our data access layer
1:09
from SQLAlchemy over to MongoDB, using MongoEngine.
1:13
Why are we doing this?
1:14
Partly to offer up another alternative data backend.
1:17
If you want to use MongoDB, I love it.
1:19
It's a great database. You can use that.
1:22
But more importantly even to highlight the real power
1:26
some of these design patterns that are not specific
1:28
to Flask but I'm going to bring in to the course
1:31
things like view models and other certain abstractions
1:35
that will let us do that switch with almost no effort.
1:39
I mean we're talking minutes, maybe an hour
1:42
if you are doing this from scratch right.
1:44
A really really quick and easy and safe way
1:47
to switch from a relational database to a non-relational
1:50
database and I think you'll really appreciate
1:52
the design patterns after that.
1:55
Our editor of choice is going to be PyCharm so
1:58
PyCharm is really great at both being a Python editor
2:01
and web editor and we'll see that at work.
2:04
And finally when we talk about deployment
2:06
we're going to be using Ubuntu.
2:08
So you're going to learn a little bit about Linux
2:10
about uWSGI, about Nginx, how you deploy
2:12
all this stuff on the cloud and we're going to put
2:14
the web app that we build out there in the internet
2:17
for everyone to see and enjoy, at least temporarily.
2:21
Well this is just the highlights of what you're going to learn
2:23
but I think these are all pretty awesome things
2:25
to get good at.
