0:00 Welcome to htmx and Flask,
0:03 Modern Python web applications hold the JavaScript. If you're building rich interactive web applications,
0:10 you might think you must use lots of JavaScript on the frontend.
0:13 Your choices are not whether or not to use javascript,
0:17 they are: should I use VueJS or React or some other framework that is
0:22 going to come out in six months. In this class,
0:25 we're going to talk about htmx.
0:28 This is a really cool JavaScript library,
0:31 that is basically the last bit of JavaScript that we need for many amazing interactive features
0:37 on our website. So instead of working with these rich JavaScript frameworks like Vue or
0:43 React and then following the conclusion that well,
0:47 if you're doing almost all the work in JavaScript on the front end and you're just
0:52 barely talking to the backend,
0:54 maybe the back end should just be NodeJS or a bunch of static files,
0:57 talking to cloud lambda functions or something like that.
1:01 You know, what we're going to say is let's reverse that.
1:04 Let's put the emphasis back on the server-side where we can write richer code in
1:09 a variety of languages and technologies. In our case,
1:12 of course, Python and Flask.
1:14 And we're going to include htmx in our page, and it will turn on a
1:19 bunch of features, but those features are driven by the server-side. We'll use cool little
1:25 HTML attributes to say this page or this part of the page is driven by this
1:30 thing on the server and htmx takes it from there.
1:33 There's almost no JavaScript to write to get very,
1:36 very similar behaviors, but you can choose any technology that you like.
1:41 We're also going to see some really cool libraries,
1:44 some open source libraries that I created for both Jinja and the Chameleon temple language in
1:49 Python that allow us to create composable, reusable elements of HTML.
1:55 This turns out to be incredibly useful for Python web applications in general,
1:59 but it's extremely helpful for the way htmx works as you'll see.
2:04 So if you've been looking to create interactive dynamic web pages,
2:08 kind of like you would with Vue or React,
2:11 but you really don't want to switch your entire tech stack over to JavaScript,
2:14 you want to keep doing Python with Flask or Django or one of these server-side
2:18 frameworks, but get the same outcome.
2:21 Well, htmx is going to be extremely exciting for you, and I think you're
2:24 gonna love this technology. Let's get into it.
