# shadow
# create-svelte
The blog software for Shadow Hosting.
Everything you need to build a Svelte project, powered by [`create-svelte`](https://github.com/sveltejs/kit/tree/main/packages/create-svelte).
## Creating a project
If you're seeing this, you've probably already done this step. Congrats!
```bash
# create a new project in the current directory
npm create svelte@latest
# create a new project in my-app
npm create svelte@latest my-app
```
## Developing
Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
```bash
npm run dev
# or start the server and open the app in a new browser tab
npm run dev -- --open
```
## Building
To create a production version of your app:
```bash
npm run build
```
You can preview the production build with `npm run preview`.
> To deploy your app, you may need to install an [adapter](https://kit.svelte.dev/docs/adapters) for your target environment.

<h1>About this app</h1>
<p>
This is a <a href="https://kit.svelte.dev">SvelteKit</a> app. You can make your own by typing the
following into your command line and following the prompts:
</p>
<pre>npm create svelte@latest</pre>
<p>
The page you're looking at is purely static HTML, with no client-side interactivity needed.
Because of that, we don't need to load any JavaScript. Try viewing the page's source, or opening
the devtools network panel and reloading.
</p>
<p>
The <a href="/sverdle">Sverdle</a> page illustrates SvelteKit's data loading and form handling. Try
using it with JavaScript disabled!

<div class="text-column">
<h1>How to play Sverdle</h1>
<p>
Sverdle is a clone of <a href="https://www.nytimes.com/games/wordle/index.html">Wordle</a>, the
word guessing game. To play, enter a five-letter English word. For example:
</p>
<div class="example">
<span class="close">r</span>
<span class="missing">i</span>
<span class="close">t</span>
<span class="missing">z</span>
<span class="exact">y</span>
</div>
<p>
The <span class="exact">y</span> is in the right place. <span class="close">r</span> and
<span class="close">t</span>
are the right letters, but in the wrong place. The other letters are wrong, and can be discarded.
Let's make another guess:
</p>
<div class="example">
<span class="exact">p</span>
<span class="exact">a</span>
<span class="exact">r</span>
<span class="exact">t</span>
<span class="exact">y</span>
</div>
<p>This time we guessed right! You have <strong>six</strong> guesses to get the word.</p>
<p>
Unlike the original Wordle, Sverdle runs on the server instead of in the browser, making it
impossible to cheat. It uses <code>&lt;form&gt;</code> and cookies to submit data, meaning you can
even play with JavaScript disabled!
