Svelte.js, commonly known simply as Svelte, is a modern JavaScript framework for building user interfaces. It’s similar to Vue.js and React.js but there’s a key difference – instead of doing most of the work in the browser, Svelte shifts that work into a compile step when the app is being built. The result is highly efficient code that surgically updates the Document Object Model (DOM).
Here is a simple guide to use Svelte.js:
1. Installation: First, you need to have Node.js and npm installed in your system. Once you have them, you can install Svelte by creating a new project using degit, a project scaffolding tool. Use the following command:
\`\`\` npx degit sveltejs/template svelte-app \`\`\` Then move to the new project directory and install the dependencies: \`\`\` cd svelte-app npm install \`\`\`1. Running the app: You can run the app using the command `npm run dev` and it will start a local development server. You can open your app by going to localhost:5000 on your browser.
1. Creating components: In Svelte, everything is considered a component. A component is a single file with a .svelte extension that contains HTML, JavaScript, and CSS code. Create your .svelte files in the “src” directory.
1. Using components: To use these components, you just have to import them into a parent component or into your main.js file like: `import ComponentName from ‘./ComponentName.svelte’;` and use it in your markup like `
1. Building the app: Once done with the development, you can create an optimized version of your app using `npm run build`.
Remember that like any framework, Svelte has its own learning curve, so it’s ideal to go through the official documentation for a more in-depth understanding.
