Welcome to the vibrant realm of PreJSS—a fast, component-friendly, and fully customizable CSS-to-JSS adapter that bridges the gap between CSS and JSS. In this blog, we’ll embark on a journey to explore the basic usage of PreJSS, breaking down each step with clarity and creativity.

What is PreJSS?

Think of PreJSS as a translator that converts your familiar CSS style language into JSS, the style notation used by libraries like React. It harnesses the power of PostCSS and turns your plain CSS, SCSS, or LESS styles directly into JSS objects on the fly.

Getting Started

Let’s dive into how to integrate PreJSS into your JavaScript application.

Installation

• Open your terminal.
• Run the following command to install PreJSS:

npm install prejss --save

Understanding the Code: An Analogy

To make sense of the coding structure, let’s visualize it as a recipe. Imagine that writing styles is like crafting a dish. The ingredients (your CSS properties) are combined and seasoned with techniques (your JSS functional style).

• The base ingredients are your plain CSS.
• By substituting or enhancing them with spices (i.e., JSS methods), you create a new and flavorful dish (your final JSS object).

This is exactly how PreJSS operates—it allows you to mix and match CSS styles with JSS functionalities while retaining the best of both worlds.

Basic Example

Here’s a simple example of how you would declare styles using PreJSS:

import preJSS from 'prejss';

const styles = preJSS`
  $bg-default: #ccc;
  button {
    color: props => props.isPrimary ? 'palevioletred' : 'green';
    display: block;
    margin: 0.5em 0;
    font-family: Helvetica, Arial, sans-serif;
    :hover {
      text-decoration: underline;
      animation: rotate360 2s linear infinite;
    }
  }
`;

Rendering with Vanilla JS and React

After defining your styles, you can render them in your application as shown below:

import jss from 'jss';
import preset from 'jss-preset-default';
import styles from './styles';

jss.setup(preset());
const classes = jss.createStyleSheet(styles).attach();

document.body.innerHTML = `
  

    Button
  
`;

For rendering with React, the process is equally straightforward. Simply inject the styles into your components using injectSheet to give them a boost!

Troubleshooting Tips

As you dive into the world of PreJSS, you might encounter a few hiccups along the way. Here are some troubleshooting steps:

• Style Not Applying: Ensure that you have correctly imported and used the PreJSS styles in your components.
• Module Not Found: Double-check that you’ve installed PreJSS and that your import paths are correct.
• Async Issues: If you’re running into performance problems while using async adapters, correctly implement async/await syntax for smoother execution.

If you are facing persistent issues, consider reaching out for help or check for updates on the PreJSS repository.
