Have you ever heard of typestyle? No? It is a great no-webpack styling solutions. In my life I tried almost everything possible:

pure CSS

SCSS

SASS

CSS modules

CSS Next

inline react styles

typestyle

Most of solutions are bundled with webpack which means if you want to write library which have extendable replacable styles included you mustn’t use webpack! So automatically you need to disqualificate these solutions:

CSS Next

CSS modules

SCSS

SASS

pure CSS

So lets take a closer look on these:

inline react styles

typestyle

Inline react styles are nice but producing spaghetti code

import * as React from 'react' export const MyInlineComponent = ( { children , style } ) => ( < div style = { { fontSize : 15 , ... style , } } > { children } </ div > )

Moreover you cannot include media and hover directives. Using onmouseover is ugly though and you need state to control that.

Lets try with typestyle then

import * as React from 'react' import { style , classes , media } from 'typestyle' export const MyComponentStyle = style ( { fontSize : 15 , $nest : { '&:hover' : { fontSize : 18 , } , } , } , media ( { maxWidth : 480 } , { fontSize : 10 } ) ) const MyNewStyle = classes ( MyComponentStyle , style ( { color : '#0ae' , } ) ) export const MyStyledComponent = ( { children , style = '' } ) => ( < div className = { classes ( MyNewStyle , style ) } > { children } </ div > )

Looks great yeah? It is high time for advanced programmers style solution. Imagine a component which have more styles. I will write styles in separate file for this solution

styles.tsx

import { style } from 'typestyle' export const Title = style ( { fontSize : 18 , } ) export const SubTitle = style ( { fontSize : 18 , } ) export const ImageSize = style ( { width : 20 , height : 20 , } )

component.tsx

import * as React from 'react' import * as styles from './styles' export const MyStyledComponent = ( { overrideStyles = { } , } : { overrideStyles : typeof styles } ) => { const componentStyles = { ... styles , ... overrideStyles , } return ( < div > < div className = { componentStyles . Title } > Hello </ div > < div className = { componentStyles . SubTitle } > World </ div > < img className = { componentStyles . ImageSize } src = " https://source.unsplash.com/random " /> </ div > ) }

usingComponent.tsx

import * as React from "react" ; import { style } from "typestyle" ; import { MyStyledComponent } from "./component" ; const Page = ( ) => ( < div > < MyStyledComponent overrideStyles = { { Title : style ( { color : "#00F" } ) } } /> </ div > ) ;

Voila you can use the component and override its styles with full intelisense!! Just by using typeof on the module.
