theme-class-provider v1.0.1

theme-class-provider

A react library that simplifies theming in your applications. It offers a ThemeClassProvider component and a convenient hook (useThemeClass) to access and manage the theme throughout your app.

Installation

You can install theme-class-provider using npm or yarn:

npm install theme-class-provider
# or
yarn add theme-class-provider

Usage

To integrate theme-class-provider into your React application, follow these steps:

1. Installation

First, install the theme-class-provider package via npm or yarn:

npm install theme-class-provider

or

yarn add theme-class-provider

2. Usage

Wrap your root component with the ThemeClassProvider component provided by the library. This component manages the theme context for your application:

import React from "react";
import ReactDOM from "react-dom";
import { ThemeClassProvider } from "theme-class-provider";
import App from "./App";

const themeClasses = ["red", "green", "blue"];

ReactDOM.render(
    <ThemeClassProvider themeClasses={themeClasses}>
        <App />
    </ThemeClassProvider>,
    document.getElementById("root")
);

In the above example, themeClasses is an array of class names representing different themes. You can customize this array based on your application's requirements.

3. Accessing Theme Context

To access the theme context within your components, utilize the useThemeClass hook provided by the library:

import React from "react";
import { useThemeClass } from "theme-class-provider";

const MyComponent = () => {
    const { getCurrentTheme, toggleTheme } = useThemeClass();

    const currentTheme = getCurrentTheme();

    return (
        <div className={currentTheme}>
            <button onClick={toggleTheme}>Toggle Theme</button>
            <p>Current Theme: {currentTheme}</p>
        </div>
    );
};

export default MyComponent;

4. Setting Up Light and Dark Themes

To define your light and dark theme styles, create corresponding CSS classes:

/* index.css */

.light {
    color-scheme: light;
    /* Light theme styles */
}

.dark {
    color-scheme: dark;
    /* Dark theme styles */
}

/* Additional body styles */

5. Wrapping Your App Component

Finally, wrap your App component with ThemeClassProvider:

import { ThemeClassProvider } from "theme-class-provider";

// Function to set the default theme based on user preferences
const setDefaultTheme = () => {
    return window.matchMedia("(prefers-color-scheme: dark)").matches
        ? "dark"
        : "light";
};

ReactDOM.render(
    <React.StrictMode>
        {/** configure the persistance behaviour as the application demands */}
        <ThemeClassProvider
            defaultTheme={setDefaultTheme()}
            themeClasses={["light", "dark"]}
            persist={{ clearOnUnload: true }}
        >
            <App />
        </ThemeClassProvider>
    </React.StrictMode>,
    document.getElementById("root")
);

Persistence Configuration and Theme Class Context Functions

Persistence Configuration

The ThemeClassProvider component allows you to configure persistence options for managing theme data. Here are the available configuration options:

• key: The key used for storing theme data.
• disabled: Indicates whether persistence is disabled.
• clearOnUnload: Clear the persisted data when the component unmounts.

By default, the library uses localstorage to persist the data.

Theme Class Context Functions

The useThemeClass hook provides access to various functions for managing the theme class context. Here's an overview of these functions:

• toggleTheme(): void: Toggles the theme class.
• setCurrentTheme(theme_class: string): void: Sets the current theme class.
• getCurrentTheme(): string: Retrieves the name of the current theme class.
• setThemeClasses(classes: string[]): void: Sets the theme classes to the provided array.
• getThemeClasses(): string[]: Retrieves the list of theme classes.
• clearPersistedThemeData(): void: Clears the persisted theme data.
• setDefault(theme_class: string): void: Sets the default theme class.
