Svelte vs Vue.js: What are the differences?

### Svelte vs Vue.js

Svelte and Vue.js are two popular front-end frameworks that aim to simplify web development by providing efficient ways to create interactive web applications. However, there are key differences between the two that developers should consider before choosing one over the other.

1. **Compilation Approach**: Svelte compiles the user interface components at build time into highly optimized vanilla JavaScript code, resulting in smaller bundle sizes and improved performance. In contrast, Vue.js uses a runtime compiler that interprets the templates at runtime, which can impact the overall performance compared to Svelte.
   
2. **Reactivity System**: Vue.js utilizes a reactive system where changes to data are automatically reflected in the UI using reactivity tracking. On the other hand, Svelte uses a reactive declaration system where reactive statements are explicitly defined, making it more intuitive for developers to understand the data flow within the components.
   
3. **Size and Overhead**: Svelte has a smaller bundle size compared to Vue.js due to its compile-time approach, which eliminates the need for a runtime library in the final output. This results in faster initial loading times and better performance for Svelte applications, especially in resource-constrained environments.
   
4. **Build Time vs Runtime**: Svelte shifts the heavy lifting of optimizing the application to build time, ensuring that the final output is as efficient as possible for the browser to interpret. In contrast, Vue.js keeps some of the optimization work at runtime, which can affect the overall performance but offers more flexibility during development.
   
5. **Learning Curve**: Vue.js follows a more traditional approach to web development with concepts like templates, directives, and components, making it easier for developers familiar with other frameworks to transition. Svelte, on the other hand, introduces a new paradigm of writing components as reactive statements, which may require a steeper learning curve for those new to reactive programming.
   
6. **Ecosystem and Community Support**: Vue.js has a larger and more established ecosystem with a wide range of plugins, tools, and community support, making it easier for developers to find resources and solutions to common problems. While Svelte's ecosystem is growing rapidly, it may not have the same level of maturity and community support as Vue.js.

In Summary, Svelte and Vue.js differ in their compilation approach, reactivity system, size and overhead, build time vs runtime optimization, learning curve, and ecosystem support.

Advice on Vue.js, Svelte

Vue.js

React

I find using Vue.js to be easier (more concise / less boilerplate) and more intuitive than writing React. However, there are a lot more readily available React components that I can just plug into my projects. I'm debating whether to use Vue.js or React for an upcoming project that I'm going to use to help teach a friend how to build an interactive frontend. Which would you recommend I use?

Nuxt.js

Our whole Vue.js frontend stack (incl. SSR) consists of the following tools:

@{Nuxt.js}|tool:7304| consisting of @{Vue CLI}|tool:9559|, @{Vue Router}|tool:6932|, @{vuex}|tool:6705|, @{Webpack}|tool:1682| and @{Sass}|tool:1171| (Bundler for @{HTML5}|tool:2538|, @{CSS 3}|tool:6727|), @{Babel}|tool:2739| (Transpiler for @{JavaScript}|tool:1209|),
Vue Styleguidist as our style guide and pool of developed @{Vue.js}|tool:3837| components
@{Vuetify}|tool:6163| as Material Component Framework (for fast app development)
@{TypeScript}|tool:1612| as programming language
@{Apollo}|tool:5508| / @{GraphQL}|tool:3820| (incl. @{GraphiQL}|tool:7879|) for data access layer (https://apollo.vuejs.org/)
@{ESLint}|tool:3337|, @{TSLint}|tool:5561| and @{Prettier}|tool:7035| for coding style and code analyzes
@{Jest}|tool:830| as testing framework
@{Google Fonts}|tool:2652| and @{Font Awesome}|tool:3244| for typography and icon toolkit
@{NativeScript-Vue}|tool:9623| for mobile development

The main reason we have chosen Vue.js over React and AngularJS is related to the following artifacts:

Empowered HTML. Vue.js has many similar approaches with Angular. This helps to optimize HTML blocks handling with the use of different components.
Detailed documentation. Vue.js has very good documentation which can fasten learning curve for developers.
Adaptability. It provides a rapid switching period from other frameworks. It has similarities with Angular and React in terms of design and architecture.
Awesome integration. Vue.js can be used for both building single-page applications and more difficult web interfaces of apps. Smaller interactive parts can be easily integrated into the existing infrastructure with no negative effect on the entire system.
Large scaling. Vue.js can help to develop pretty large reusable templates.
Tiny size. Vue.js weights around 20KB keeping its speed and flexibility. It allows reaching much better performance in comparison to other frameworks.

Decided

Svelte is everything a developer could ever want for flexible, scalable frontend development. I feel like React has reached a maturity level where there needs to be new syntactic sugar added (I'm looking at you, hooks!). I love how Svelte sets out to rebuild a new language to write interfaces in from the ground up.

Detailed Comparison

Vue.js	Svelte
It is a library for building interactive web interfaces. It provides data-reactive components with a simple and flexible API.	If you've ever built a JavaScript application, the chances are you've encountered – or at least heard of – frameworks like React, Angular, Vue and Ractive. Like Svelte, these tools all share a goal of making it easy to build slick interactive user interfaces. Rather than interpreting your application code at run time, your app is converted into ideal JavaScript at build time. That means you don't pay the performance cost of the framework's abstractions, or incur a penalty when your app first loads.

What are some alternatives to Vue.js, Svelte?

jQuery

jQuery is a cross-platform JavaScript library designed to simplify the client-side scripting of HTML.

AngularJS

AngularJS lets you write client-side web applications as if you had a smarter browser. It lets you use good old HTML (or HAML, Jade and friends!) as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. It automatically synchronizes data from your UI (view) with your JavaScript objects (model) through 2-way data binding.

React

Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.

jQuery UI

Whether you're building highly interactive web applications or you just need to add a date picker to a form control, jQuery UI is the perfect choice.

Ember.js

A JavaScript framework that does all of the heavy lifting that you'd normally have to do by hand. There are tasks that are common to every web app; It does those things for you, so you can focus on building killer features and UI.

Backbone.js

Backbone supplies structure to JavaScript-heavy applications by providing models key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing application over a RESTful JSON interface.

Angular

It is a TypeScript-based open-source web application framework. It is a development platform for building mobile and desktop web applications.

Aurelia

Aurelia is a next generation JavaScript client framework that leverages simple conventions to empower your creativity.

Flux

Flux is the application architecture that Facebook uses for building client-side web applications. It complements React's composable view components by utilizing a unidirectional data flow. It's more of a pattern rather than a formal framework, and you can start using Flux immediately without a lot of new code.

Famo.us

Famo.us is a free and open source JavaScript platform for building mobile apps and desktop experiences. What makes Famo.us unique is its JavaScript rendering engine and 3D physics engine that gives developers the power and tools to build native quality apps and animations using pure JavaScript.
