Build Setup

Using Svelte with other technologies (e.g. PostCSS, SCSS, TypeScript, and Babel)

Svelte doesn’t build in any opinions on the kind of JavaScript, CSS, or even HTML you write. Therefore, if you want to use any nonstandard syntax, you need to put that into your bundler plugin chain or Svelte’s preprocessors. Here we will describe the top usecases for doing this.

• Transpiling ES6 to ES5 for Legacy Browser (IE11) Support with Babel
• Using Future JS Syntax in Svelte with Babel
• Using PostCSS with Svelte
• Using TypeScript with Svelte
• Writing Your Own Preprocessors
