Create a Multiple Instances Socket React Context Library: a Step-by-Step Guide

2023-01-16

In this article, we will go through the process of creating a multiple instances socket React context library using socket.io to create a real-time communication between different parts of your application. The Providers component serves as the starting point for initializing various modules for a complete separate instance. The Socket Service initializes basic methods such as initializing socket.io, event listeners, subscriptions, and unsubscriptions. The core feature of our library is the SocketContextService, which is responsible for maintaining a map of contexts and updating or removing them as needed. The React app imports the standalone Provider component, which wraps a child component and initializes the SocketService and SocketContext as a separate instance. SocketContextProvider creates a context for sharing data and functions related to socket.io connection across multiple components in the application. It accepts props such as url, socketContextId, and incomingEvents and uses hooks like useEffect, useMemo, useRef, and useState to create state variable data, initialize context, create socket service and handle incoming events, disconnection, and context removal. It also exports socket, sentEvent, subscribeEvents and unsubscribeEvents as value to be consumed by the child components.
