Svelte.js – The Complete Guide (incl. Sapper.js)

Build high-performance web applications with SvelteJS – a lightweight JavaScript compiler

What you’ll learn
SvelteJS from scratch, with zero knowledge assumed
All the theory and practical applications of Svelte
Core concepts and advanced techniques to build Svelte applications

Requirements
Basic JavaScript knowledge is required
NO prior knowledge about SvelteJS or any other JavaScript framework or library is required

Description
Svelte.js is a
modern JavaScript compiler
that allows you to write easy-to-understand JavaScript code which is then compiled to highly efficient code that runs in the browser.
You’ll write your frontend application using normal JavaScript, following specific rules laid out by Svelte (which are of course taught in this course). As a result, the Svelte compiler will produce a small and highly optimized JavaScript bundle which can be deployed.
In this course, you learn all about Svelte, how it works, its core features and how to run your final app on a real server!
Svelte.js is a tool for building highly reactive, modern user interfaces for the web –
and it’s a great alternative to JavaScript frameworks
and libraries like
React.js, Angular or Vue
.
What will you learn?
What is Svelte and why would you use it?
All the core features and base syntax
How to render conditional and list content
How to write reactive and fast web applications
All about components, how to pass data around and how to create re-usable building blocks
How to efficiently manage data in your application via Svelte stores
How to reach out to a backend server and send + fetch data
How to pre-render your app on a server and improve SEO
Is this course for you?
Svelte is a
popular alternative to React.js, Angular and Vue
and learning it will benefit any frontend web developer.
You don’t need to know these frameworks to learn Svelte though – but if you do know them, you’ll learn about an interesting alternative which might allow you to build your web projects with less code (and get an
even faster app
along the way!).
You need
NO advanced JavaScript knowledge
, basic knowledge will do.
If you’re interested in building modern, reactive user interfaces that load quickly and run fast, SvelteJS is a tool you shouldn’t overlook!

Who’s teaching you?
My name is Maximilian Schwarzmüller and I’m teaching a broad variety of web & mobile development topics here on Udemy. I immediately loved Svelte when I learned about it since it fills an important gap between vanilla JavaScript and frameworks like Angular, React or Vue.
It can be used to replace these frameworks or to enhance apps built with them – and I simply love lightweight apps and clean syntax rules.
Who this course is for
Beginner and advanced JavaScript students who are interested in writing high-performance frontend applications
Students who already know modern JavaScript frameworks and want to learn about a lightweight, production-ready alternative
