🌟 Creating your own Custom Component Library for SvelteKit #

You can create a SvelteKit component library to level up your workflow. There are possibly a few components you use over and over in new SvelteKit apps you create. You might be copy-pasting the component into each new project. If you want a maintainability boost, how about you create a SvelteKit component library? With that done all you have to do is import components into your new app like you do any external dependency. The bonus is you make changes once, in you component library and they are propagated through to all your apps via the famous npm update command.

If that sounds like a productivity boost you'd sign up for, get your typing fingers out then hit play on the video.

Create a SvelteKit Component Library in 10 Steps

1. Decide which components from an existing app you want to add to your component library.
2. Create a skeleton SvelteKit project.

   pnpm init [email protected] my-sveltekit-component-library && cd $_
   pnpm install

3. Add the components you decided on to src/lib folder.
4. Create a lib/index.ts. Import your components then export them as named exports.

   import Map from '$lib/components/Map.svelte';
    
   export { Map };

5. Edit package.json, adding this line:

   "svelte": "index.js"

6. Install the svelte2tsx package:

   pnpm install -D svelte2tsx

7. Generate the package using svelte-kit package:

   npx svelte-kit package

8. Test locally, by creating a new skeleton project which uses the created package. Link using the relative path of the created package in the test site's package.json:

   "@rodneylab/sveltekit-components": "link:../../components/package",

9. Push your package to npm:

   npm whoami
   npm login
   npm publish --access public ./package

10. Install the npm package on your test site to check it works:

    pnpm install -D @you/yourpackage
