How do I set up an event bus in React?

To set up an event bus in React, you can use a simple JavaScript object or a library like EventEmitter.

Can you show me a basic example using a JavaScript object?

Sure! You can create an event bus like this:

const EventBus = {};
EventBus.events = {};

EventBus.on = function(event, callback) {
    if (!this.events[event]) {
        this.events[event] = [];
    }
    this.events[event].push(callback);
};

EventBus.emit = function(event, data) {
    if (this.events[event]) {
        this.events[event].forEach(callback => callback(data));
    }
};

You can then use EventBus.on to listen for events and EventBus.emit to trigger them.

How do I integrate this with my React components?

You can import the EventBus into your components and use it to communicate between them. For example, in one component, you can emit an event when a button is clicked, and in another component, you can listen for that event.

What if I want to use a library instead?

You can use libraries like mitt or EventEmitter3 for a more robust solution. They provide similar functionality with additional features.
