Welcome to the world of Linaria! This innovative library allows you to write CSS in JavaScript without the performance overhead that typically accompanies CSS-in-JS solutions. Together, we will explore how to install, set up, and utilize Linaria effectively, along with troubleshooting techniques to help you along the way.

Features of Linaria

• Writes CSS in JS with zero runtime—styles are extracted during the build process.
• Utilizes familiar Sass-like nested CSS syntax.
• Supports dynamic prop-based styles using CSS variables.
• Includes CSS sourcemaps for easier debugging.
• Allows for CSS linting with stylelint.
• Supports any CSS preprocessor, including Sass and PostCSS.
• Facilitates atomic styles with @linaria/atomic.

Installation

To get started with Linaria, you’ll need to install a few packages. Here’s how to set it up with npm or yarn:

• Using npm: npm install @linaria/core @linaria/react @wyw-in-js/babel-preset
• Using yarn: yarn add @linaria/core @linaria/react @wyw-in-js/babel-preset

Setup

Linaria is built on top of wyw-in-js.dev and supports various bundlers. You can check the specific configuration guides for:

• Webpack
• Esbuild
• Rollup
• Vite
• Svelte

Basic Syntax

Let’s delve into some basic usage. Think of Linaria like a theater director assigning roles to actors. The CSS functions and structures become the actors, while you, as the director, will dictate how they perform together to create a beautiful scene:

import { css } from '@linaria/core';
import modularScale from 'polished';

const header = css`
  text-transform: uppercase;
  font-family: $fonts.heading;
  font-size: ${modularScale(2)};
`;

In this example, header class is styled dynamically with the font-size calculated based on modular scale. Just like a well-crafted play, where each actor knows their role, Linaria styles beautifully integrate into your components.

Creating Components

Using Linaria with React is intuitive. By employing styled-components-like syntax, styling becomes a playful choreographed dance:

import styled from '@linaria/react';

const Title = styled.h1`
  font-family: $families.serif;
`;

const Container = styled.div`
  font-size: $sizes.medium;
  color: ${props => props.color};
  
  &:hover {
    border-color: blue;
  }
`;

// Usage

  

This brings to life the component structure, with dynamic styles made easy, all without incurring any runtime costs.

Troubleshooting

While Linaria streamlines coding, you may encounter some hiccups. Here are some common issues and fixes:

• Styling Not Applying: Ensure your CSS is properly linked in your build configuration and there are no linting errors.
• Dynamic Styles Not Working in IE11: Remember that dynamic styles using CSS custom properties don’t support IE11; consider alternative styling approaches.
• Errors with Package Versions: When facing compatibility issues, check if the installed versions of Linaria and your build tools are aligned. Keeping everything updated can resolve many conflicts.
