Starting With Svelte – Brittney Postma

Svelte is a modern JavaScript framework that makes building web applications a breeze. If you’re new to Svelte and looking to get started, you’ve come to the right place. In this article, we’ll explore the basics of Svelte and how you can begin using it to create amazing web applications.

What is Svelte?

Svelte is a radical new approach to building user interfaces. It moves the work of building and manipulating the DOM from the browser to a compile step. This means that you write your components in a familiar HTML, CSS, and JavaScript syntax, and Svelte takes care of the heavy lifting of updating the DOM efficiently.

Getting Started

To start using Svelte, you’ll need to install it on your machine. You can do this using a package manager like npm:

$ npm install svelte

Once Svelte is installed, you can create a new Svelte project using the command line:

$ npx degit sveltejs/template my-svelte-app
$ cd my-svelte-app
$ npm install
$ npm run dev

This will create a new Svelte project and start a development server where you can see your app in action.

Creating Components

In Svelte, components are reusable pieces of code that encapsulate a part of your user interface. To create a new component, you simply need to create a new .svelte file and write your markup, styles, and logic inside it.

<script>
    let name = 'World';

</script>

<h1>Hello {name}!</h1>

<style>
    h1 {
        color: #333;
    }
</style>

Here, we’ve created a simple component that displays a greeting message. We’ve defined a variable ‘name’ and used it in our markup to display a personalized greeting.

Wrapping Up

Starting with Svelte can seem daunting at first, but once you get the hang of it, you’ll love its simplicity and power. Whether you’re building a small project or a large-scale application, Svelte has got you covered. So go ahead, dive in, and start building amazing web applications with Svelte!
