React components and hooks for dash-ui

npm i @dash-ui/react

Quick Start

NOTE: You do not need to use this package to use @dash-ui with React. This merely provides a few useful utilities, particularly on the server-side.

Check out an example on CodeSandbox

import { createStyles } from "@dash-ui/styles";
import { useGlobal } from "@dash-ui/react";

const styles = createStyles({
  tokens: {
    color: {
      primary: "#ee5b5f",
    },
  },
});

const Heading = () => {
  useGlobal(
    styles,
    ({ color }) => `
      h1 {
        font-size: 2rem;
        font-family: -apple-system, sans-serif;
        color: ${color.primary};
      }
    `,
    []
  );

  return <h1>Hello world</h1>;
};

API docs

Components

Component	Description
`<Inline>`	A component for creating an inline `<style>` tag that is unmounted when the component unmounts.

Hooks

Hook	Description
`useCSS()`	A hook for performantly and reliably inserting CSS into the DOM in React 18 using the `useInsertionEffect` hook.
`useGlobal()`	A hook for inserting transient global styles into the DOM. These styles will be injected when the hook mounts and flushed when the hook unmounts.
`useTokens()`	A hook for inserting transient CSS tokens into the DOM. These tokens will be injected when the hook mounts and flushed when the hook unmounts.
`useThemes()`	A hook for inserting transient CSS theme tokens into the DOM. These tokens will be injected when the hook mounts and flushed when the hook unmounts.

Server rendering

	Description
`<Style>`	A React component for injecting SSR CSS styles into Next.js documents.
`toComponent()`	A function for creating a React `<style>` component for inserting Dash styles in SSR.
`createGatsbyRenderer`	Creates a Gatsby replaceRenderer for injecting styles generated by Dash on the server into the Gatsby `<head>` component

TypeScript support

Dash is written in TypeScript. It's also strongly typed, creating a beautiful IntelliSense experience in VSCode and providing solid insurance to your TypeScript application.

	Description
Strongly typed tokens	Learn how to add autocomplete and type safety to your CSS tokens.
Strongly typed themes	Learn how to add autocomplete and type safety to your CSS variable themes.

<Inline>

A component for creating an inline <style> tag that is unmounted when the component unmounts.

Strongly typed tokens

To use variable types with @dash-ui/react, you have to use the module declaration pattern:

Play with this example on CodeSandbox

const tokens = {
  color: {
    red: "#c17",
  },
};

type AppTokens = typeof tokens;

declare module "@dash-ui/styles" {
  export interface DashTokens extends AppTokens {}
}

// OR alternatively
declare module "@dash-ui/styles" {
  export interface DashTokens {
    color: {
      red: string;
    };
  }
}

Strongly typed themes

To use variable/theme types with @dash-ui/react, you have to use the module declaration pattern:

Play with the example on CodeSandbox

const themes = {
  light: {
    color: {
      // var(--color-bg)
      bg: "#fafafa",
    },
  },
  dark: {
    color: {
      // var(--color-bg)
      bg: "#1a1a1a",
    },
  },
};

type AppThemes = typeof themes;
type AppTokens = AppThemes["dark"] & AppThemes["light"];

declare module "@dash-ui/styles" {
  export interface DashTokens extends AppTokens {}
  export interface DashThemes extends AppThemes {}
}

// OR alternatively
declare module "@dash-ui/styles" {
  export interface DashTokens {
    color: {
      bg: string;
    };
  }

  export interface DashThemes {
    light: DashTokens;
    dark: DashTokens;
  }
}
