Los problemas que resuelve SolidJS

Why learn Solid.js?

Solid.js is not just another framework in the vast universe of web development. This framework represents the future, built with features and tools that optimize the developer experience. What's surprising is that Netlify, a leading cloud solutions company, hired Ryan Carniato, the creator of Solid, to lead its open source efforts. What makes Solid so special? Its reactivity system, known as "Pyongreen Reactivity", puts it at the forefront, surpassing even the famous trifecta of React, Angular and Vue.

How do Solid and React compare?

To better understand these differences, we compared Solid to React through a simple task list application (TodoList) in both frameworks.

What happens in React?

• Initialization: When a React application starts, it validates the entire component to set its initial state.
• Dynamic state: For example, the checked state of an item in a list can change over time.
• Virtual DOM: React needs to reanalyze and reconcile its entire tree (virtual DOM) every time there is a change. This includes, in addition to the elements that actually change, any other updates to the DOM.
• Inefficiency: This constant revalidation causes React to be at the bottom of the benchmarks in terms of efficiency when manipulating or removing elements in large lists.

What makes Solid different?

• Single initialization: Solid only validates the component on its first initialization in the DOM. After that, your changes do not require full revalidation.
• Granular efficiency: Changes in the element tree, such as modifying an input, do not require revalidating everything, but only the specific elements that actually change.
• List management: When deleting or adding items, Solid revalidates and adjusts only the affected items. This demonstrates its superior efficiency in genuine reactive operations.

How do you project this efficiency into the future?

Solid has made such an impact that other frameworks have begun to mimic its approach. For example, Vue has adopted a system known as "Vapor", inspired by Solid and free of virtual DOM. React, meanwhile, has introduced similar server components, and Angular has implemented signals, similar to Solid's system.

What can I expect from learning Solid?

I am Samuel Bourbano, Senior Software Engineer with more than 12 years in web development. Over the years, I have witnessed the evolution of the web ecosystem with innovative technologies. I have contributed to open source projects such as VideoJS and Solid.js itself. In this course, you will learn how to use Solid from scratch, the basic and advanced concepts, and you will get to create your own "Minisolid", a reactive library that will allow you to deeply understand how this system works. Wherever you are in your career path, Solid.js offers you to take your skills to the next level.
