@stylable/runtime v6.0.2

@stylable/runtime

@stylable/runtime provides the utility that is used to create the stylesheet functions that apply classNames and states to the DOM. It also exposes an optional DOM renderer that is responsible for loading CSS in its correct order.

End-users will usually not add this package directly as a dependency themselves, and would instead receive it as a dependency of their chosen integration (e.g. @stylable/webpack-plugin).

Usage

@stylable/runtime exposes two methods, Stylesheet and Renderer.

Stylesheet

When importing a Stylable stylesheet, there are multiple named exports that are exposed for usage.

import { 
    style, 
    classes, 
    vars, 
    stVars, 
    keyframes, 
    layers, 
    containers, 
    cssStates 
} from './local.st.css';

Style utility function

The style function is useful for creating the root node of you component, passing along classes passed through props, or whenever a state is being defined.

style(
    contextClassName: string, stateOrClass: string | StateMap, ...classes: string[]
)

import { style, classes } from './local.st.css';

// properties passed to the component externally
props = { className: "app__root app--propstate" };

// The classes export exposes a map of classNames and their namespaced values.
classes.root;
// returns "local__root"

<div className={style(classes.root)} />
// becomes <div className="local__root" /> 

<div className={style(classes.root, { localState: true })} />
// becomes <div className="local__root local--localstate" /> 

<div className={style(classes.root, { localState: true }, props.className)} />
// becomes <div className="local__root local--localstate app__root app--propstate" /> 

<div className={style(classes.root, 'global-class', props.className)} />
// becomes <div className="local__root global-class app__root app--propstate" /> 

<div className={classes.part} />
// becomes <div className="local__part" /> 

Renderer

Responsible for managing CSS files, linking to the document and maintaining their correct order in your application.

TypeScript integration

When importing a Stylable stylesheet in TypeScript, a global module declaration needs to be defined in order to not receive type errors about unknown imports.

Add the following file to your /src directory.

// globals.d.ts
declare module '*.st.css' {
    export * from '@stylable/runtime/stylesheet';

    const defaultExport: unknown;
    export default defaultExport;
}
