An opinionated starter template to create shareable Svelte components, featuring:
Clone with degit and install dependencies
$ npx degit zerodevx/svelte-component my-component
$ cd my-component
$ npm i
Your component's source code lives in src/Component.svelte.
You can create a package that exports multiple components by adding them to the src directory and editing src/index.js to reexport them as named exports.
Start the server:
$ npm run dev
This serves the /docs directory at http://localhost:5000, and doubles-up as a demo site as well via Github Pages.
Your package.json has a "svelte" field pointing to src/index.js, which allows Svelte apps to import the source code directly, if they are using a bundler plugin like rollup-plugin-svelte or svelte-loader (where resolve.mainFields in your webpack config includes "svelte"). This is recommended.
For everyone else, npm run build will bundle your component's source code into a plain JavaScript module (dist/index.mjs) and a UMD script (dist/index.js). This will happen automatically when you publish your component to npm, courtesy of the prepublishOnly hook in package.json.
