typestyle-react

Simplified integration between TypeStyle and React.

Installation

npm install --save typestyle-react
# or
yarn add typestyle-react

API

styled

type styled = (tag: string, ...properties: (NestedCSSProperties | ((props: {}) => NestedCSSProperties))[]) => React.Component;

Create a React component with styles applied.

import { styled } from "typestyle-react";

const RedText = styled("span", {
  color: "red"
});

// Renders a `<span class="…">…</span>`, where `class` is computed by TypeStyle.
let element = <RedText>Hello world!</RedText>;

Components pass-through supported props, so they can be used the same as the unstyled originals.

element = <RedText id="my-red-text">Hello world!</RedText>;

Caveats:

• If className is passed, its value will be merged with the TypeStyle computed value.
• Using ref will expose the wrapped component, use innerRef to access the inner element.

Parameterised Styles

Styling can be parameterised, and be passed values via props. Instead of passing an CSSNestedProperties object to styled, pass a function:

import { styled } from "typestyle-react";

const ColoredText = styled("span", (props: { color: string }) => ({
  color: "red"
}));

// Styled props passed via the special `styled` prop.
let element = <ColoredText styled={{ color: "red" }}>Hello world!</ColoredText>;

Hint: Don't confuse the styled prop with the native style prop.

style

type style = (...properties: NestedCSSProperties[]) => string;

A wrapper around TypeStyle's style export that schedules forceRenderStyles() in a microtask.

import { style } from "typestyle-react";

const coloredTextStyle = style({
  color: "red"
});

let element = <span className={coloredTextStyle}>Hello world!</span>;

StyleSheet flushing to DOM

Styles are computed (via TypeStyle) when the component is rendered, and are immediately scheduled to be flushed to the DOM synchronously.
