<h2 class="anchored" data-anchor-id="introduction">Introduction</h2>
<p>Quite some time ago I started attempting to learn python and web development. I claim in no way to be even close to an expert on either one of those things, in fact I am truly a beginner at both. While I never continued with python I have always enjoyed web development, creating quite a few small R Shiny apps along the way. As I have decided to learn Julia I am instantly drawn to Web Development, and I decided to try out the Genie Framework. While there exist some tutorials on the web, I find the all contain small pieces of information but lack putting everything together. Form my learning python days, I know that there exists a WONDERFUL tutorial for the python Flask framework (<a href="https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world">Found Here</a>). I decided to challenge myself and recreate his website using Genie, and the Model, View, Controller model. I will attempt to document what I do to try and help others along the way. As stated above I AM NOT AN EXPERT, so at any time there is a good chance I am not doing something the best way possible! I encourage everyone to follow along and make suggestions for improvements. I am going to try my best to go in the order Miguel did, but for some chapters I will skip sections or combine things as needed to make them work for the framework.</p>
</section>
<section id="getting-started" class="level2">
<h2 class="anchored" data-anchor-id="getting-started">Getting Started</h2>
<p>Miguels blog does a great job of going into installing python and flask as well as setting up virtual environments in python. I am going to skip most of this as there is great documentation out there on how to install Julia and set up a project (Genie will actually take care of this for us). Instead I will link here what I would say are the three prerequisites for getting started.</p>
<ul>
<li><a href="https://julialang.org/downloads/">Download and install Julia</a></li>
<li>The IDE of your choice (I use VSCode, and the <a href="https://marketplace.visualstudio.com/items?itemName=julialang.language-julia">Julia Extension</a>)</li>
<li>Add Genie to your Julia environment (see below)</li>
</ul>
<p>To add Genie to your Julia environment, open the Julia REPL and type the following:</p>
<div class="sourceCode" id="cb1"><pre class="sourceCode julia code-with-copy"><code class="sourceCode julia"><span id="cb1-1"><a href="#cb1-1" aria-hidden="true" tabindex="-1"></a>pkg<span class="op">&gt;</span> add Genie <span class="co"># press ] from julia&gt; prompt to enter Pkg mode</span></span></code><button title="Copy to Clipboard" class="code-copy-button"><i class="bi"></i></button></pre></div>
</section>
<section id="creating-the-app" class="level2">
<h2 class="anchored" data-anchor-id="creating-the-app">Creating The App</h2>
<p>Genie will take care of creating a new directory for us, but we will want to open the Julia REPL from whatever directory we want the app folder to live in. Once that has been decided open a Julia REPL and type the following:</p>
<div class="sourceCode" id="cb2"><pre class="sourceCode julia code-with-copy"><code class="sourceCode julia"><span id="cb2-1"><a href="#cb2-1" aria-hidden="true" tabindex="-1"></a>julia<span class="op">&gt;</span> <span class="im">using</span> <span class="bu">Genie</span></span>
<span id="cb2-2"><a href="#cb2-2" aria-hidden="true" tabindex="-1"></a></span>
<span id="cb2-3"><a href="#cb2-3" aria-hidden="true" tabindex="-1"></a>julia<span class="op">&gt;</span> Genie.Generator.<span class="fu">newapp</span>(<span class="st">"Microblog"</span>)</span></code><button title="Copy to Clipboard" class="code-copy-button"><i class="bi"></i></button></pre></div>
<p>Upon executing the command, Genie will:</p>
<ul>
<li>make a new dir called <code>Microblog</code> and <code>cd()</code> into it,</li>
<li>install all the apps dependencies</li>
<li>create a new Julia project (adding the Project.toml and Manifest.toml files),</li>
<li>activate the project,</li>
<li>automatically load the new apps environment into the REPL,</li>
<li>start the web server on the default Genie port (port 8000) and host (127.0.0.1 aka <code>localhost</code>).</li>
</ul>
<p>At this point you can confirm that everything worked as expected by visiting <a href="http://127.0.0.1:8000">http://127.0.0.1:8000</a> in your favorite web browser. You should see Genies welcome page. If at any point you want to exit the REPL and reload the app perform the following:</p>
<div class="sourceCode" id="cb3"><pre class="sourceCode julia code-with-copy"><code class="sourceCode julia"><span id="cb3-1"><a href="#cb3-1" aria-hidden="true" tabindex="-1"></a>julia<span class="op">&gt;</span> <span class="im">using</span> <span class="bu">Genie</span></span>
<span id="cb3-2"><a href="#cb3-2" aria-hidden="true" tabindex="-1"></a></span>
<span id="cb3-3"><a href="#cb3-3" aria-hidden="true" tabindex="-1"></a>julia<span class="op">&gt;</span> Genie.<span class="fu">loadapp</span>()</span>
<span id="cb3-4"><a href="#cb3-4" aria-hidden="true" tabindex="-1"></a></span>
<span id="cb3-5"><a href="#cb3-5" aria-hidden="true" tabindex="-1"></a>julia<span class="op">&gt;</span> <span class="fu">up</span>()</span></code><button title="Copy to Clipboard" class="code-copy-button"><i class="bi"></i></button></pre></div>
<p>This will reload the app and activate the web server. You can again visit <a href="http://127.0.0.1:8000">http://127.0.0.1:8000</a> to test that everything is working.</p>
</section>
<section id="creating-a-hello-world-genie-app" class="level2">
<h2 class="anchored" data-anchor-id="creating-a-hello-world-genie-app">Creating a Hello World Genie App</h2>
<p>While Genie by default has a welcome page, lets change it to a simple Hello World page to make the app our own. Open routes.jl and change the “/” route to the following:</p>
<div class="code-with-filename">
<div class="code-with-filename-file">
<pre><strong>routes.jl</strong></pre>
</div>
<div class="sourceCode" id="cb4" data-filename="routes.jl"><pre class="sourceCode julia code-with-copy"><code class="sourceCode julia"><span id="cb4-1"><a href="#cb4-1" aria-hidden="true" tabindex="-1"></a><span class="fu">route</span>(<span class="st">"/"</span>) <span class="cf">do</span></span>
<span id="cb4-2"><a href="#cb4-2" aria-hidden="true" tabindex="-1"></a> <span class="st">"Hello World!"</span></span>
<span id="cb4-3"><a href="#cb4-3" aria-hidden="true" tabindex="-1"></a><span class="cf">end</span></span></code><button title="Copy to Clipboard" class="code-copy-button"><i class="bi"></i></button></pre></div>
</div>
<p>If we go to <a href="http://127.0.0.1:8000">http://127.0.0.1:8000</a> we should now see the following:</p>
<div class="quarto-figure quarto-figure-center">
<figure class="figure">
<p><img src="helloworldscreenshot.png" class="img-fluid figure-img"></p>
<figcaption>Hello World Screenshot</figcaption>

## Introduction
Quite some time ago I started attempting to learn python and web development. I claim in no way to be even close to an expert on either one of those things, in fact I am truly a beginner at both. While I never continued with python I have always enjoyed web development, creating quite a few small R Shiny apps along the way. As I have decided to learn Julia I am instantly drawn to Web Development, and I decided to try out the Genie Framework. While there exist some tutorials on the web, I find the all contain small pieces of information but lack putting everything together. Form my learning python days, I know that there exists a WONDERFUL tutorial for the python Flask framework ([Found Here](https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world)). I decided to challenge myself and recreate his website using Genie, and the Model, View, Controller model. I will attempt to document what I do to try and help others along the way. As stated above I AM NOT AN EXPERT, so at any time there is a good chance I am not doing something the best way possible! I encourage everyone to follow along and make suggestions for improvements. I am going to try my best to go in the order Miguel did, but for some chapters I will skip sections or combine things as needed to make them work for the framework.
## Getting Started
Miguel's blog does a great job of going into installing python and flask as well as setting up virtual environments in python. I am going to skip most of this as there is great documentation out there on how to install Julia and set up a project (Genie will actually take care of this for us). Instead I will link here what I would say are the three prerequisites for getting started.
- [Download and install Julia](https://julialang.org/downloads/)
- The IDE of your choice (I use VSCode, and the [Julia Extension](https://marketplace.visualstudio.com/items?itemName=julialang.language-julia))
- Add Genie to your Julia environment (see below)
To add Genie to your Julia environment, open the Julia REPL and type the following:
```julia
pkg> add Genie # press ] from julia> prompt to enter Pkg mode
```
## Creating The App
Genie will take care of creating a new directory for us, but we will want to open the Julia REPL from whatever directory we want the app folder to live in. Once that has been decided open a Julia REPL and type the following:
```julia
julia> using Genie
julia> Genie.Generator.newapp("Microblog")
```
Upon executing the command, Genie will:
- make a new dir called ```Microblog``` and ```cd()``` into it,
- install all the app's dependencies
- create a new Julia project (adding the Project.toml and Manifest.toml files),
- activate the project,
- automatically load the new app's environment into the REPL,
- start the web server on the default Genie port (port 8000) and host (127.0.0.1 -- aka ```localhost```).
At this point you can confirm that everything worked as expected by visiting [http://127.0.0.1:8000](http://127.0.0.1:8000) in your favorite web browser. You should see Genie's welcome page.
If at any point you want to exit the REPL and reload the app perform the following:
```julia
julia> using Genie
julia> Genie.loadapp()
julia> up()
```
This will reload the app and activate the web server. You can again visit [http://127.0.0.1:8000](http://127.0.0.1:8000) to test that everything is working.
## Creating a Hello World Genie App
While Genie by default has a welcome page, lets change it to a simple Hello World page to make the app our own. Open routes.jl and change the "/" route to the following:
```{.julia filename="routes.jl"}
route("/") do
"Hello World!"
end
```
If we go to [http://127.0.0.1:8000](http://127.0.0.1:8000) we should now see the following:
