SOLID

What is Solid?

Solid is a framework in JavaScript designed for creating dynamic web applications. Leveraging your existing proficiency in HTML and JavaScript, Solid empowers you to construct reusable components for your application. The framework offers tools to augment these components with reactivity, employing declarative JavaScript code to establish a connection between the user interface and the underlying data, thereby facilitating a more interactive and responsive user experience.

Understanding the Structure of a Solid App

In a Solid App, the fundamental building blocks are functions referred to as components. Consider the HelloWorld function presented on the right, which directly returns a div. This amalgamation of HTML and JavaScript is known as JSX. Solid comes equipped with a compiler that transforms these JSX tags into DOM nodes during runtime.

With JSX, you can employ most HTML elements in your app, and it also allows the creation of new elements. Once you've defined a function like HelloWorld, you can utilize it as a tag throughout your application.

The central starting point for any Solid App is the render function. This function takes two parameters: a function encapsulating your application logic and an existing HTML element to mount onto. Here's an example:

render(() => <HelloWorld/>, document.getElementById("app"));

This line of code establishes the entry point for the Solid App, rendering the HelloWorld component within the HTML element with the ID "app."

Why Solid?

Solid is a JavaScript web framework that prioritizes responsiveness and performance while maintaining a lightweight and finely grained structure. Its emphasis is on ensuring that the development process is as seamless and predictable as the user experience. This is achieved through several key features:

• Granularity: Solid eliminates the need for a virtual DOM, updating only the necessary components, contributing to efficient and targeted updates.

• User-Friendly: It boasts an intuitive design, making it easy to learn for both newcomers and those with prior experience in web development.

• Comprehensive: Solid encompasses all the essential elements required for constructing impressive projects, providing a well-rounded framework for diverse development needs.

PREACT

What is Preact?

Preact, a JavaScript library, is crafted as a nimble and lightweight substitute for React. Notably, it maintains compatibility with React, allowing developers to seamlessly transition from a minimum viable product (MVP) to a full-fledged React application if necessary. With a diminutive virtual DOM and a mere 3KB in size, Preact facilitates swift transfers from server to client, optimizing overall load times. Moreover, it offers a compatibility layer with React, serving as a seamless drop-in replacement.

Choosing Between Preact and React: Key Features and Distinctions

The decision between Preact and React hinges on the specific needs of your project. While they share numerous features, there are notable differences to consider.

Key Features and Differences: Preact vs React

To determine the most suitable option, assess whether Preact's functionality meets your project requirements or if you need the additional features provided by React. Additionally, consider factors such as project complexity, size, and performance when making your decision.

• Complexity: Opt for React if your project demands a more feature-rich and flexible API. Preact, with its simpler API, may not encompass all the advanced features offered by React.

• Size: Preact boasts a smaller bundle size compared to React. This attribute is advantageous for optimizing application load times and minimizing bandwidth usage. If size is a critical consideration, Preact might be the preferable choice.

• Performance: Preact excels in performance with a faster and more efficient virtual DOM implementation than React. It is particularly well-suited for constructing high-performance applications. If performance is a top priority for your project, Preact could be the better choice.

Creating UI with Preact: A Guide and Example

Building user interfaces with Preact involves assembling trees of components and elements. Components, which can be functions or classes, provide a description of the output for their tree. This description is commonly expressed in JSX or HTM, utilizing standard JavaScript Tagged Templates. Both syntaxes allow the definition of element trees with "props" (similar to HTML attributes) and children.

To initiate your journey with Preact, focus on the render() function. This function takes a tree description and constructs the specified structure. It then appends this structure to a designated parent DOM element, given as the second argument. Subsequent render() calls reuse the existing tree, updating it in-place within the DOM. Internally, render() calculates differences from previous outputted structures to minimize DOM operations.

import { h, render } from 'preact';

render(
  <main>
    <h1>Hello</h1>
  </main>,
  document.body
);

render(
  <main>
    <h1>Hello World!</h1>
  </main>,
  document.body
);

The render() function transforms the structure into a user interface. While this simple example works, managing a growing application's complexity would be challenging. Components come to the rescue by dividing the UI into nested components, allowing each to calculate differences independently. Here's an example incorporating Preact components:

import { render, h } from 'preact';
import { useState } from 'preact/hooks';

const App = () => {
  const [input, setInput] = useState('');

  return (
    <div>
      <p>Do you agree to the statement: "Preact is awesome"?</p>
      <input value={input} onInput={e => setInput(e.target.value)} />
    </div>
  );
};

render(<App />, document.body);

This example showcases the creation of a Preact component, demonstrating how components contribute to more manageable and efficient UI development.

VUE

What is Vue?

Vue, pronounced as /vjuː/ like "view," is a JavaScript framework designed for constructing user interfaces. It enhances the capabilities of standard HTML, CSS, and JavaScript by providing a declarative and component-based programming model. This approach facilitates efficient development of user interfaces, whether they are simple or intricate.

Here's a minimal example showcasing Vue's core features:
JavaScript:

JavaScript:

import { createApp, ref } from 'vue'

createApp({
  setup() {
    return {
      count: ref(0)
    }
  }
}).mount('#app')

Html:

<div id="app">
  <button @click="count++">
    Count is: {{ count }}
  </button>
</div>

Result:

Count is: 0

Result:
This example highlights two fundamental aspects of Vue:

Declarative Rendering: Vue extends standard HTML with a template syntax, allowing the declarative description of HTML output based on JavaScript state.
