Stylin: A built-time CSS library for styling React components


Stylin is a build-time CSS library that offers an elegant way to style React components. It extends CSS Modules and adds some missing features like dynamic variables or auto-typing.

There is no faster way to create styled & typed React component.

import {Title} from './styles.scss'
// crazy part, importing 👆 component from styles

<Title color="tomato" size="small">
  Hello world!

💅 style.scss

  @tag: h1
  @component: Title
  size: small | medium | large
  color: #38383d --color
.title {
  --color: #38383d;
  color: var(--color);
  font-size: 18px;
  &.small {
    font-size: 14px;
    margin: 2px 0;
  &.medium {
    font-size: 18px;
    margin: 4px 0;
  &.large {
    font-size: 20px;
    margin: 6px 0;

🧙‍♂️ Type auto-generation


All the magic is behind the style annotations, which you can find in the comment section. It is like JSDoc, but for CSS. However, it is not a CSSDoc. It is more about mapping styles with component properties.

With the annotations you can:

  • map styles with components
  • generate TypeScript types
  • generate documents or even stories for StoryBook

For all these, you will need a specific package, plugin, or webpack loader. 


✨ Online demo
✨ Github repo 

Get started

The core library:

npm install @stylin/style
npm install --save-dev @stylin/msa-loader

Then you should add the loader in your webpack configs files:

Diving deeper

Don't be scared to learn new stuff, it is deadly simple. Only three things to remember:

  1. @tag: html tag
  2. @component: name of your component
  3. Mapping object:
componentPropertyName {
  propertyValue: css-class-name
  anotherPropertyValue: another-css

For example:

  @tag: button
  @component: SexyButton
  type {
    primary: btn-primary
    secondary: bnt-secondary
    link: btn-link
.sexy-button {
  &.btn-primary { 
    /* some styles */
  &.btn-secondary { 
    /* some styles */
  &.btn-link { 
    /* some styles 
<SexyButton type='primary'>
  Love me

/* HTML output:
<button class="sexy-button btn-primary"> //in fact, it will have hashed css class names
  Love me


Done! That is all about to know! ğŸŽ‰ğŸ¥³

Now you are the PRO ğŸ˜Ž. Update your resume with a new skill! 


Here are some tips to make life easier.

If your component property values are similar to CSS class names, like in the example below:

type {
  primary: primary
  secondary: secondary
  link: link

It can be shorten this way:

type: primary | secondary | link
