Ore
Ore is a JavaScript / TypeScript package that simplifies the consumption of Server-Sent Events (SSE) in web applications. It provides an easy-to-use interface for establishing SSE connections, handling incoming events, and implementing retry strategies in case of connection failures.
Motivation
Consuming Server-Sent Events (SSE) or streaming data in web applications isn't always well-documented and can be complex or just plain unreliable to implement. Ore aims to simplify this process by providing a straightforward and reliable way to consume SSE streams.
Features
- Establish SSE connections with ease.
- Handle incoming SSE events and process them accordingly.
- Implement retry strategies for reconnecting to the SSE endpoint in case of connection failures.
- Customizable headers for SSE requests.
- Set maximum retries for connection attempts.
Install
npm install @glamboyosa/ore
Usage
import Ore from "@glamboyosa/ore";
// Initialize Ore with URL and optional headers
const ore = new Ore({
url: "http://example.com/sse-endpoint",
headers: {
"Cache-Control": "no-cache",
},
});
// Start SSE connection
ore.fetchSSE(
(buffer, parts) => {
console.log("Received buffer:", buffer);
// Process the received buffer
const b = parts[parts.length - 1];
console.log("Received parts i.e. events", parts);
console.log("Buffer per event", b);
// process the buffer per event
},
() => {
console.log("Stream ended");
// Handle stream end
}
);
Class Parameters
url
:string
- The URL of the SSE endpoint.headers
:HeadersInit
(optional) - Optional headers to include in the SSE request. Must be an object where keys are header names and values are header values.
fetchSSE
Function Parameters
onBufferReceived
:function
- Callback function to handle received SSE buffers. Receives the buffer and the optionally the parts i.e. new events as a parameter.onStreamEnded
:function
- Callback function to handle stream end events. Receives the internal state of if the buffer stream is ended.retries
:number
(optional) - Optional parameter to specify the maximum number of retry attempts. Default is 3.
Working with React Server Components
While Ore is intended to work with client components, it is possible to use it in server components using the fetchSSEForRSC
function. The function takes optional retries
: number
(optional) - Optional parameter to specify the maximum number of retry attempts. Default is 3. and customHeaders
: HeadersInit
(optional) - Optional headers to include in the SSE request. Must be an object where keys are header names and values are header values.
