We're using Sapper to build a fast and statically exported website
However you get the code, you can install dependencies and run the project in development mode with:
yarn
yarn dev
Open up localhost:3000 and start clicking around.
Consult sapper.svelte.dev for help getting started.
- use CSS custom properties for variables
- use speaking variable names (rather longer and clear than short and meaningless)
- always use variables for colors
- always use variables for changing (eg. media queries) or configurable values (component props / css overrides)
- define local variables on top and global variable on
:root
or:host
- use namespaced variable names:
- do:
:root { --color-primary: #ff00ff; --color-border: #ff00ff; } .button { --btn-bg-color: var(--btn-bg-color); --btn-border-color: var(--color-border); --btn-border-width: 1px; --btn-border-style: solid; background-color: var(--btn-bg-color-primary); border-color: var(--btn-border-color); border-width: var(--btn-border-width); border-style: var(--btn-border-style); }
- don't do:
.btn { --primary: #ff00ff; --border: 1px solid #333; background: var(--primary); border: var(--border); }
- do:
Sapper expects to find two directories in the root of your project — src
and static
.
The src directory contains the entry points for your app — client.js
, server.js
and (optionally) a service-worker.js
— along with a template.html
file and a routes
directory.
This is the heart of your Sapper app. There are two kinds of routes — pages, and server routes.
Pages are Svelte components written in .svelte
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
src/routes/about.svelte
corresponds to the/about
route. A file calledsrc/routes/blog/[slug].svelte
corresponds to the/blog/:slug
route, in which caseparams.slug
is available to the route - The file
src/routes/index.svelte
(orsrc/routes/index.js
) corresponds to the root of your app.src/routes/about/index.svelte
is treated the same assrc/routes/about.svelte
. - 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
src/routes/_helpers/datetime.js
and it would not create a/_helpers/datetime
route
The static directory contains any static assets that should be available. These are served using sirv.
In your service-worker.js file, you can import these as files
from the generated manifest...
import { files } from '@sapper/service-worker';
...so that you can cache them (though you can choose not to, for example if you don't want to cache very large files).
Sapper uses Rollup or webpack to provide code-splitting and dynamic imports, as well as compiling your Svelte components. With webpack, it also provides hot module reloading. As long as you don't do anything daft, you can edit the configuration files to add whatever plugins you'd like.
To start a production version of your app, run yarn build && yarn start
. This will disable live reloading, and activate the appropriate bundler plugins.
Run yarn export
to create a static production build in the __sapper__/export
dir.
