🚀 Spinning up a New Svelte App

We see how to create a Svelte app from scratch in this post. This will be handy equally if you are new to Svelte and want to hit the ground running or have more experience but want a cheatsheet. If you are a Svelte pro, but can never remember the spin-up commands, you can treat the post like a cheatsheet with the commands for a skeleton SvelteKit project. We focus on creating a Svelte app with SvelteKit here. However if you prefer Astro for quickly spinning up a Svelte app, there’s a link lower down for how to do this, but with Astro. I really hope you find it useful, and please do reach out or drop a comment below if there is something missing. You can find contact details further down the page.

🧱 How to Create a Svelte App

To get going you will need to have NodeJS installed on your system. At the time of writing, you should have NodeJS version 16.9 or higher to run the latest version of SvelteKit. NodeJS comes with the npm packet manager, but we use pnpm: performance npm here. The benefit is that it keeps a local cache of packages on your machine. This saves you downloading a package if you already used the same version in another project.

How to Create a Svelte App

• To set the ball rolling, run the Create Svelte app command.

  pnpm create svelte@next my-new-svelte-app && cd $_ && code .
  

  Here our project gets created in a new my-new-svelte-app directory. “&& cd$_” will put us in the new directory when everything is ready. “&& code . will open up VSCode in the new directory (change this to &ldquo&& codium .” or “&& subl .” if you use Codium or Sublime Text).
• Next, the CLI gives you some options for configuring your project. You can select Skeleton project if you want just the basics and then to build the rest up yourself. Alternatively, the SvelteKit demo app option gives you some training wheels (stabilisers). Next you can go all in on TypeScript or if you are not a fan opt for no type checking or JavaScript with JSDoc. If you are comfortable with TypeScript then choose that option. Otherwise, even if you are not a huge TypeScript fan, I would go for the JSDoc option. This adds some TypeScript benefits like Intellisense and auto-completion without having to be strict about your types. Finally, you can choose ESLint for code linting, Prettier for formatting and Playwright for end-to-end testing. You can opt in to whichever of these you want to use.

Making all pages static

• SvelteKit lets you build static (SSG) or server-server side rendered apps. A third option is mixing the two. If you want to go for the first, static, option, create a src/routes/+layout.ts or src/routes/+layout.js file with this content: ```javascript // OPTIONAL: fully SSG (static site) only

export const prerender = true;

- Spin up the dev server:
```shell
pnpm dev

The CLI will give you a link so you can open the new app in your browser, the default is localhost:5173/. If you already have something running on TCP port 5713 SvelteKit will find another free port.

That’s all there is to it! If you are new to SvelteKit, check out the free Getting Started with SvelteKit Guide for 10 tips to help you hit the ground running. Also see the Starting out Svelte and SvelteKit tutorial which even goes right up to publishing your SvelteKit site on Netlify, Cloudflare or Vercel.
