Concept: Polling is a simpler approach where the client regularly requests data from the server at specified intervals.
The client uses setInterval to periodically make AJAX calls to the server. The server responds with the latest data. Example:
setInterval(() => {
fetch('/latestProjectData')
.then(response => response.json())
.then(data => {
// Update the UI with the new data
});
}, 5000); // Poll every 5 seconds
Server-Sent Events (SSE)
Concept:
Server-Sent Events (SSE) allow a server to push data to the client. It's a one-way communication from server to client, suitable for scenarios where the client doesn't need to send data back to the server in real-time.
Backend Implementation:
Use Express to send updates via SSE.
Clients listen for these events and update their UI accordingly.
Example:
Backend
Frontend Implementation: Create an EventSource to listen for updates from the server. Example:
