Svelte Webpack Starter
This is my personal starter template for creating Svelte apps. It's preconfigured out of the box with Webpack, TypeScript, SASS, Babel, Autoprefixer, and hot module replacement. I've kept it minimal and organized so it's easy to build upon and/or customize.
Getting started
Installation
To quickly get started with this template, use degit:
npx degit baileyherbert/svelte-webpack-starter svelte-app
cd svelte-app
Then, install dependencies.
npm install
Starting the development server
The dev
script will compile the app, start the development server, and enable hot replacement for components and styles. Open http://localhost:8080 in your browser to see the app.
npm run dev
Building for production
The build
script will compile the app for production. By default, the bundle will be created at /public/build/
, which means your public directory will contain everything you need to run the app.
npm run build
To run the production build, use the start
command and open http://localhost:8080 in your browser.
npm run start
Usage
Global styles
The /src/styles/index.scss
file will be compiled and embedded at the top of the bundled CSS, effectively making it a global stylesheet. You can easily add additional stylesheets to the bundle by editing the stylesheets
variable at the top of webpack.config.js
:
const stylesheets = [
'./src/styles/index.scss'
];
Single page applications
If you're building a single page application (which needs multiple routes), edit your package.json file:
- Add the
--history-api-fallback
flag to the"dev"
command - Add the
--single
flag to the"start"
command.
"scripts": {
"dev": "webpack-dev-server [...] --history-api-fallback",
"start": "serve [...] --single",
}
Targeting browsers
Babel and Autoprefixer will be used to make bundles work in your target browsers, which are listed under browserslist
in your package.json file. Check out the list of browserslist queries to customize this.
{
"browserslist": [
"defaults"
]
}
Note that Babel is only active for production builds by default, so it won't slow down your development.
Disabling Babel
If you don't need to support older browsers, you can reduce your bundle size by disabling Babel. Just change the useBabel
variable at the top of webpack.config.js
:
const useBabel = false;
Enabling source maps in production
By default, this template won't generate source maps for production bundles in order to avoid exposing your source code. If you need to enable source maps in production (such as for debugging), update the sourceMapsInProduction
variable at the top of webpack.config.js
.
const sourceMapsInProduction = true;
Path mapping
By default, the src
alias is mapped to your src/
directory, which means you can import like this:
import Navbar from 'src/components/Navbar.svelte';
If you wish to add additional aliases, you only need to edit the paths
property in your tsconfig.json
, and they will be automatically applied to Webpack:
"paths": {
"src": ["src"]
}
