Usage

1. Define your theme

Create a TypeScript object with your theme specifications. Colors will always be needed and can contain as many color schemes as you want. Important: To make sure that your theme will work as intended use it in its own file, for example theme.ts

import { ThemeType } from "react-vario-theme";

export const varoTheme = {
  colors: {
    light: {
      primary: "#007bff",
      text: {
        default: "#6c757d",
        link: "#007bff",
      },
    },
    dark: {
      primary: "#007bff",
      text: {
        default: "#6c757d",
        link: "#007bff",
      },
    },
  },
  padding: {
    sm: "5px",
    md: "10px",
    lg: "20px",
  },
} as const satisfies ThemeType;

2. Generate css variables

npx react-vario-theme compile "path to your theme object" "path and name of the css/sass file you want to create" When the css variables are generated they can be used in css or in react using the theme context provider.

Compile: npx react-vario-theme compile src/styles/theme.ts src/styles/theme.scss
Watch: npx react-vario-theme compile src/styles/theme.ts src/styles/theme.scss --watch

3. Optional: Tailwind support

You can get all your theme css variables in tailwind using "tailwindTheme"

import { tailwindColors, tailwindTheme } from "react-vario-theme";
import { type Config } from "tailwindcss";
import { varoTheme } from "./src/styles/theme";

export default {
  content: ["./src/**/*.{js,ts,jsx,tsx}"],
  theme: tailwindTheme(varoTheme),
  plugins: [],
} satisfies Config;

3. Use `VarioThemeProvider`

Wrap your application with the VarioThemeProvider.

import { varoTheme } from "~/styles/theme";
import { VarioThemeProvider } from "react-vario-theme";

const App = () => {
  return (
    <VarioThemeProvider theme={varoTheme}>
      <Component {...pageProps} />
    </VarioThemeProvider>
  );
};

4. Access Theme Variables

You can now access theme variables anywhere within your components.

import { useVarioTheme } from "react-vario-theme";
import { varoTheme } from "~/styles/theme";
const MyComponent = () => {
  const { theme, colorScheme, changeColorScheme } =
    useVarioTheme<typeof varoTheme>();

  return (
    <button
      style={{ backgroundColor: theme.colors.primary }}
    >
      Click Me
    </button>
  );
};
