usecontext multiple provider

If you need to provide data to multiple providers, it's best to use context, because it is a way to pass data through the React component tree without having to pass props down manually at every level.

When you need to provide data to multiple providers, you have to use a Context Provider component. This component is used to supply the data to the other components that need it. The context provider component should be at the same level as the components that will use the data.

To set up a context provider, you first need to create a context object. This is done using the React.createContext() method. After you create the context, the Provider component needs to be wrapped around the component tree that needs access to the data. This can be done using the React.Component.render() method.

In order to receive data from the Provider component, you need to wrap the component in a Consumer component. The Consumer component takes a function as an argument, and this function receives the data from the Provider component. The data that is received is then used in the component.

To provide data to multiple providers, you can create multiple context objects and Provider components, and wrap the component tree with the Consumers. This allows you to provide multiple sets of data to different parts of the component tree.


// Create the context
const Context = React.createContext();

// Create the Provider component
class Provider extends React.Component {
    render() {
        return (
            // Wrap the component tree in the Provider component
            <Context.Provider value={this.props.data}>
                {this.props.children}
            </Context.Provider>
        )
    }
}

// Create the Consumer component
const Consumer = (props) => (
    <Context.Consumer>
        {(data) => {
            // Use the data in the component
            return props.children(data);
        }}
    </Context.Consumer>
)

// To use multiple providers, create multiple context objects andProvider components, and wrap the component tree with the Consumers.

// Create the first context
const Context1 = React.createContext();

// Create the first Provider component
class Provider1 extends React.Component {
    render() {
        return (
            // Wrap the component tree in the first Provider component
            <Context1.Provider value={this.props.data1}>
                {this.props.children}
            </Context1.Provider>
        )
    }
}

// Create the first Consumer component
const Consumer1 = (props) => (
    <Context1.Consumer>
        {(data1) => {
            // Use the data in the component
            return props.children(data1);
        }}
    </Context1.Consumer>
)

// Create the second context
const Context2 = React.createContext();

// Create the second Provider component
class Provider2 extends React.Component {
    render() {
        return (
            // Wrap the component tree in the second Provider component
            <Context2.Provider value={this.props.data2}>
                {this.props.children}
            </Context2.Provider>
        )
    }
}

// Create the second Consumer component
const Consumer2 = (props) => (
    <Context2.Consumer>
        {(data2) => {
            // Use the data in the component
            return props.children(data2);
        }}
    </Context2.Consumer>
)
