TypeScript definitions for eventsource
@types/eventsource provides TypeScript definitions for the EventSource API, which is used for receiving server-sent events (SSE). This package allows TypeScript developers to use the EventSource API with type safety and autocompletion in their projects.
Creating an EventSource instance
This feature allows you to create a new EventSource instance to listen for server-sent events from a specified URL.
const eventSource = new EventSource('https://example.com/events');Listening for messages
This feature allows you to set up an event listener for incoming messages from the server. The event handler receives an event object containing the data sent by the server.
eventSource.onmessage = (event) => { console.log(event.data); };Handling errors
This feature allows you to handle errors that occur while receiving events. The event handler receives an event object that can be used to log or handle the error.
eventSource.onerror = (event) => { console.error('Error:', event); };Closing the connection
This feature allows you to close the EventSource connection when it is no longer needed, freeing up resources.
eventSource.close();The 'eventsource' package is a polyfill for the EventSource API, allowing it to be used in environments where it is not natively supported, such as Node.js. Unlike @types/eventsource, which provides TypeScript definitions, 'eventsource' provides the actual implementation of the EventSource API.
The 'sse-channel' package provides a simple way to implement server-sent events in Node.js. It allows you to create an SSE channel and send events to connected clients. This package is more focused on the server-side implementation of SSE, whereas @types/eventsource is focused on the client-side TypeScript definitions.
The 'express-sse' package is an easy-to-use SSE middleware for Express.js. It simplifies the process of setting up SSE endpoints in an Express application. This package is more about integrating SSE with Express, while @types/eventsource provides TypeScript support for the EventSource API.
