+# sapper-template
+
+The default [Sapper](https://github.com/sveltejs/sapper) template. To clone it and get started:
+
+```bash
+npx degit sveltejs/sapper-template my-app
+cd my-app
+npm install # or yarn!
+npm run dev
+```
+
+Open up [localhost:3000](http://localhost:3000) and start clicking around.
+
+
+## Structure
+
+Sapper expects to find three directories in the root of your project — `assets`, `routes` and `templates`.
+
+
+### assets
+
+The [assets](assets) directory contains any static assets that should be available. These are served using [serve-static](https://github.com/expressjs/serve-static).
+
+In your [service-worker.js](templates/service-worker.js) file, Sapper makes these files available as `__assets__` so that you can cache them (though you can choose not to, for example if you don't want to cache very large files).
+
+
+### routes
+
+This is the heart of your Sapper app. There are two kinds of routes — *pages*, and *server routes*.
+
+**Pages** are Svelte components written in `.html` files. When a user first visits the application, they will be served a server-rendered version of the route in question, plus some JavaScript that 'hydrates' the page and initialises a client-side router. From that point forward, navigating to other pages is handled entirely on the client for a fast, app-like feel. (Sapper will preload and cache the code for these subsequent pages, so that navigation is instantaneous.)
+
+**Server routes** are modules written in `.js` files, that export functions corresponding to HTTP methods. Each function receives Express `request` and `response` objects as arguments, plus a `next` function. This is useful for creating a JSON API, for example.
+
+There are three simple rules for naming the files that define your routes:
+
+* A file called `routes/about.html` corresponds to the `/about` route. A file called `routes/blog/[slug].html` corresponds to the `/blog/:slug` route, in which case `params.slug` is available to the route
+* The file `routes/index.html` (or `routes/index.js`) corresponds to the root of your app. `routes/about/index.html` is treated the same as `routes/about.html`.
+* Files and directories with a leading underscore do *not* create routes. This allows you to colocate helper modules and components with the routes that depend on them — for example you could have a file called `routes/_helpers/datetime.js` and it would *not* create a `/_helpers/datetime` route
+
+
+### templates
+
+This directory should contain the following files at a minimum:
+
+* [2xx.html](templates/2xx.html) — a template for the page to serve for valid requests
+* [4xx.html](templates/4xx.html) — a template for 4xx-range errors (such as 404 Not Found)
+* [5xx.html](templates/5xx.html) — a template for 5xx-range errors (such as 500 Internal Server Error)
+* [main.js](templates/main.js) — this module initialises Sapper
+* [service-worker.js](templates/service-worker.js) — your app's service worker
+
+Inside the HTML templates, Sapper will inject various values as indicated by `%sapper.xxxx%` tags. Inside JavaScript files, Sapper will replace strings like `__dev__` with the appropriate value.
+
+In lieu of documentation (bear with us), consult the files to see what variables are available and how they're used.
+
+
+## Webpack config
+
+Sapper uses webpack to provide code-splitting, dynamic imports and hot module reloading, as well as compiling your Svelte components. As long as you don't do anything daft, you can edit the configuration files to add whatever loaders and plugins you'd like.
+
+
+## Production mode and deployment
+
+To start a production version of your app, run `npm start`. This will disable hot module replacement, and activate the appropriate webpack plugins.
+
+You can deploy your application to any environment that supports Node 8 or above. As an example, to deploy to [Now](https://zeit.co/now), run these commands:
+
+```bash
+npm install -g now
+now
+```

+			<p>First, you have to know what <a href='https://svelte.technology'>Svelte</a> is. Svelte is a UI framework with a bold new idea: rather than providing a library that you write code with (like React or Vue, for example), it's a compiler that turns your components into highly optimized vanilla JavaScript. If you haven't already read the <a href='https://svelte.technology/blog/frameworks-without-the-framework'>introductory blog post</a>, you should!</p>
+
+			<p>Sapper is a Next.js-style framework (<a href='/blog/how-is-sapper-different-from-next'>more on that here</a>) built around Svelte. It makes it embarrassingly easy to create extremely high performance web apps. Out of the box, you get:</p>
+
+			<ul>
+				<li>Code-splitting, dynamic imports and hot module replacement, powered by webpack</li>
+				<li>Server-side rendering (SSR) with client-side hydration</li>
+				<li>Service worker for offline support, and all the PWA bells and whistles</li>
+				<li>The nicest development experience you've ever had, or your money back</li>
+			</ul>
+
+			<p>It's implemented as Express middleware. Everything is set up and waiting for you to get started, but you keep complete control over the server, service worker, webpack config and everything else, so it's as flexible as you need it to be.</p>

But we face our own hostile environment: underpowered devices, poor network connections, and the complexity inherent in front-end engineering.

+			<p><a href='https://github.com/zeit/next.js/'>Next.js</a> is a React framework from <a href='https://zeit.co'>Zeit</a>, and is the inspiration for Sapper. There are a few notable differences, however:</p>
+
+			<ul>
+				<li>It's powered by <a href='https://svelte.technology'>Svelte</a> instead of React, so it's faster and your apps are smaller</li>
+				<li>Instead of route masking, we encode route parameters in filenames. For example, the page you're looking at right now is <code>routes/blog/[slug].html</code></li>
+				<li>As well as pages (Svelte components, which render on server or client), you can create <em>server routes</em> in your <code>routes</code> directory. These are just <code>.js</code> files that export functions corresponding to HTTP methods, and receive Express <code>request</code> and <code>response</code> objects as arguments. This makes it very easy to, for example, add a JSON API such as the one powering this very page (look in <code>routes/api/blog</code>)</li>
+				<li>Links are just <code>&lt;a&gt;</code> elements, rather than framework-specific <code>&lt;Link&gt;</code> components. That means, for example, that <a href='/blog/how-can-i-get-involved'>this link right here</a>, despite being inside a blob of HTML, works with the router as you'd expect.</li>
