React Free Style

React Free Style combines Free Style with React.js by managing the style of React components dynamically. Works with server-side rendering, where only styles of rendered components will print.

Why?

Check out why you should be doing CSS in JS. This module exposes the API directly to React.js.

Even more improvements with React Free Style

Modular React.js components
Style debugging in development mode
Fast renders with automatic style for rendered React components
Supports universal/isomorphic applications

Installation

npm install react-free-style --save

Usage

Styled

1import { styled } from "react-free-style";
2
3const Button = styled("button", {
4  backgroundColor: "red",
5});
6
7const App = () => {
8  return <Button css={{ color: "blue" }}>Hello world!</Button>;
9};

JSX

1/** @jsx jsx */
2
3import { jsx } from "react-free-style";
4
5const App = () => {
6  return (
7    <button css={{ color: "blue", backgroundColor: "red" }}>
8      Hello world!
9    </button>
10  );
11};

Imperative

1import { css, useCss } from "react-free-style";
2
3// Creates "cached CSS":
4const style = css({ color: "red" });
5// But you can also write `const style = { color: "red" }`.
6
7const Button = () => {
8  const className = useCss(style);
9
10  return <button className={className}>Hello world!</button>;
11};

This is how the styled and jsx work! Knowing how it works can help you when you need to extract the class name for integrating with an existing UI library using className.

Recipes

Valid Styles

Every CSS method accepts:

CSS-in-JS object
String, i.e. a class name
Cached CSS, created using the css(...) method
Computed CSS, a function which accepts Style and returns a valid style
Array of the above

Composition

Components created using styled expose "cached CSS" on the style property.

1const LargeButton = styled("button", [
2  {
3    fontSize: 16,
4  },
5  Button.style,
6  {
7    marginBottom: 8,
8  },
9]);

Animations

A "computed CSS" function can be used to register and use @keyframes.

1import { css } from "react-free-style";
2
3const style = css((Style) => {
4  const animationName = Style.registerStyle({
5    $global: true,
6    "@keyframes &": styles,
7  });
8
9  return { animationName };
10});

Themes

CSS Variables

The most effective CSS themes I've seen use CSS variables to dynamically change styles.

1// Register this CSS wherever you want the theme to apply, e.g. `:root`.
2const theme = {
3  "--color": "red",
4};
5
6const Button = styled("button", {
7  color: "var(--color)",
8});
9
10// Later on you can change the theme.
11const style = css({
12  "--color": "blue",
13});

Context

Use React.Context to define a theme and custom components with css props.

1const ThemeContext = React.createContext({
2  color: "red",
3});
4
5const Button = () => {
6  const theme = React.useContext(ThemeContext);
7
8  return <button css={{ color: theme.color }}>Hello world!</button>;
9};

Rendering

By default, CSS output is discarded (a "no op" useful for testing) because you may have different output requirements depending on the environment.

Client-side Rendering

StyleSheetRenderer is an efficient CSS renderer for browsers.

1import { StyleSheetRenderer, Context } from "react-free-style";
2
3// const renderer = new NoopRenderer();
4const renderer = new StyleSheetRenderer();
5
6React.render(
7  <Context.Provider value={renderer}>
8    <App />
9  </Context.Provider>,
10  document.body
11);

Server-side Rendering

MemoryRenderer collects all styles in-memory for output at a later time.

1import { MemoryRenderer, Context } from "react-free-style";
2
3// const renderer = new NoopRenderer();
4const renderer = new MemoryRenderer();
5
6const content = ReactDOM.renderToString(
7  <Context.Provider value={renderer}>
8    <App />
9  </Context.Provider>,
10  document.body
11);
12
13const html = `
14<!doctype html>
15<html>
16  <head>
17    ${renderer.toString()}
18  </head>
19  <body>
20    <div id="content">
21      ${content}
22    </div>
23  </body>
24</html>
25`;
