WFPCoreProvider

The WFPCoreProvider component in React serves as a context provider, encapsulating and distributing application-wide settings, such as theming preferences.

Importing

To use WFPCoreProvider, import it along with its context and default settings:

import { WFPCoreProvider, WFPCoreContext, defaultWFPContext } from "@wfp/react";

Usage

Wrap your application or component tree with WFPCoreProvider to provide all children access to the context:

import React from "react";
import { WFPCoreProvider } from "@wfp/react";

const App = () => (
  <WFPCoreProvider>{/* Rest of the application */}</WFPCoreProvider>
);

Props

WFPCoreProvider accepts the following props to customize its behaviour:

children: ReactNode - The child components that will have access to the context.
initialTheme: string (optional) - The initial theme for the application, with "auto" as the default value to automatically match the system’s theme.
prefix: string (optional) - A prefix for CSS class naming, with "wfp" as the default value.
wrapperElement: HTMLElement (optional) - A DOM element to which the theme-specific classes will be applied. If not specified, it defaults to the document.body or a similar high-level element in your application.

Functionality

Theme Management

Automatic Theme Detection: WFPCoreProvider automatically detects the user’s system preference for light or dark mode if the initialTheme is set to "auto".
Theme Switching: It allows dynamic switching of themes via the setTheme function provided in the context. This function updates both the internal state and the class name of the wrapperElement, facilitating CSS-based theming.

Context Values

The context provided by WFPCoreProvider includes:

prefix: For CSS class naming.
selectorTabbable and selectorFocusable: Selectors for managing focusable and tabbable elements.
theme and actualTheme: Current theme settings.
initialized: A boolean indicating if the context has been initialized.
setTheme: A function to change the theme.
wrapperElement: The DOM element used for applying theme classes.

Accessing the Context

WFPCoreProvider utilizes WFPCoreContext to pass down the application settings. Components within the provider’s child tree can access these settings using the useSettings hook or the Context.Consumer pattern.

When to use

Place WFPCoreProvider at the top level of your application to ensure all components can access the context.
Utilize the provided setTheme function to change themes dynamically in response to user actions or preferences.
Use the prefix from the context for consistent naming of CSS classes and easier theme management.
