Getting Started with MagJS: A Modular Application Glue

Feb 13, 2023 | Programming

If you’re looking for a super-fast, simple, and intuitive JavaScript to HTML templating component library, you’ve come to the right place! In this article, we’ll delve into how to create your own modular applications using MagJS, and we’ll guide you step-by-step with practical examples.

Step 1: Installation

To get started with MagJS, you can easily add it to your project using npm:

npm i mag.js

Step 2: Defining Your Component

This is where the magic begins! With MagJS, defining a component is straightforward. Create a simple Counter component that keeps track of how many times a button has been clicked.

const Counter = Mag(function (props) {
  const handler = () => {
    Counter({ count: props.count + 1 });
  };
  return Mag`
    

You clicked ${props.count} times

`; });

Step 3: Rendering Your Component

Once your component is set up, it’s time to bring it to life in the browser. Here’s how to render your Counter component:

Mag(Counter({ count: 0 }), document.getElementById('root'));

Understanding the Code: An Analogy

Think of your Counter component as a small shop where you sell cookies. Each time someone clicks the “Click me” button, it’s like a customer buying a cookie. The count variable keeps a running total of how many cookies have been sold. Every click triggers an event (or customer entering the shop) that updates the count, and the shopkeeper (the component) displays the current total to all customers in the shop.

API Overview

MagJS provides several key functionalities to help you manage your components efficiently. Here’s a brief overview:

  • Render: Renders HTML content to a specified element.
  • Define Component: Sets up your component and return its render function.
  • Hooks: Maintain state and lifecycle methods within your components.

Step 4: Exploring More Examples
