Give me 2 mins and I’ll show you how to add real-time updates without WebSockets!   ⚡

Users expect dashboards, IoT panels, and monitoring tools to refresh instantly. Polling struggles to keep up.

𝐒𝐞𝐫𝐯𝐞𝐫-𝐒𝐞𝐧𝐭 𝐄𝐯𝐞𝐧𝐭𝐬 (𝐒𝐒𝐄) provide lightweight, one-way streaming over a single HTTP connection.

ASP .NET Core 10 includes native SSE support, making real-time streaming simple and efficient.

With built-in types like 𝐒𝐬𝐞𝐈𝐭𝐞𝐦<𝐓> and 𝐓𝐲𝐩𝐞𝐝𝐑𝐞𝐬𝐮𝐥𝐭𝐬.𝐒𝐞𝐫𝐯𝐞𝐫𝐒𝐞𝐧𝐭𝐄𝐯𝐞𝐧𝐭𝐬() from 𝐒𝐲𝐬𝐭𝐞𝐦.𝐍𝐞𝐭.𝐒𝐞𝐫𝐯𝐞𝐫𝐒𝐞𝐧𝐭𝐄𝐯𝐞𝐧𝐭𝐬, you can push updates using plain HTTP with almost no extra setup. 🚀

SSE works naturally with 𝐈𝐀𝐬𝐲𝐧𝐜𝐄𝐧𝐮𝐦𝐞𝐫𝐚𝐛𝐥𝐞<𝐓>, so the server sends data the moment it is produced.

In our example, your server uses:

1. TemperatureService to continuously generate readings through 𝐈𝐀𝐬𝐲𝐧𝐜𝐄𝐧𝐮𝐦𝐞𝐫𝐚𝐛𝐥𝐞<𝐓𝐞𝐦𝐩𝐞𝐫𝐚𝐭𝐮𝐫𝐞𝐄𝐯𝐞𝐧𝐭>

2. TemperatureEvent as a small record with Id, SensorId, Celsius, and Timestamp

3. A Minimal API endpoint using MapGet to stream events, set EventId, and handle resume logic via the 𝐋𝐚𝐬𝐭-𝐄𝐯𝐞𝐧𝐭-𝐈𝐃 header

On the client, the browser connects using 𝐄𝐯𝐞𝐧𝐭𝐒𝐨𝐮𝐫𝐜𝐞, listens for your event name, and automatically reconnects if the connection drops. 💡

SSE is a great fit for:
1. Live dashboards and monitoring panels
2. Log and event feeds
3. Market and price tickers
4. Notification systems

✅ Use SignalR if you need two-way communication.
✅ Use SSE if you only need updates from server to client.


P.S. SSE gives you a clean and scalable approach to real-time data delivery. It is HTTP-native, browser-friendly, and easy to implement with a few classes and namespaces.


Would you use SSE for your next real-time feature? 🤔

ASP.NET Core Server-Sent Events (SSE) by Elliot One

𝗦𝘁𝗼𝗽 𝗦𝗰𝗮𝗹𝗶𝗻𝗴 𝗛𝗲𝗮𝗱𝗮𝗰𝗵𝗲𝘀 with this Simple Architecture Change!🚀

Modern applications grow fast and traditional CRUD often slow you down. 

Mixed read and write logic leads to bloated models, tight coupling, and performance bottlenecks. 

As traffic increases, the system becomes harder to maintain and even harder to scale.

This is a common problem in maturing systems.

✅Here is the solution: 𝗖𝗤𝗥𝗦 + 𝗠𝗲𝗱𝗶𝗮𝘁𝗥 

CQRS separates write operations into Commands and read operations into Queries. 

This clear divide allows each side of the system to evolve and scale independently.

𝐖𝐡𝐲 𝐂𝐐𝐑𝐒 𝐡𝐞𝐥𝐩𝐬:

📌 Separation of Read and Write Models
 Use domain models for writes and lightweight DTOs for reads. This improves clarity and makes data retrieval more efficient.

📌 Better Scalability
 Read and write paths scale independently. High read traffic can use replicated read stores while writes stay transactional.

📌 Lower Lock Contention
 Write isolation helps maintain performance in high-concurrency environments.

📌 Cleaner, More Maintainable Architecture
 Commands, queries, and handlers keep the system modular and easier to reason about.

But CQRS brings many moving parts. 

That is where MediatR steps in.

𝗛𝗼𝘄 𝗠𝗲𝗱𝗶𝗮𝘁𝗥 𝘀𝗶𝗺𝗽𝗹𝗶𝗳𝗶𝗲𝘀 𝗲𝘃𝗲𝗿𝘆𝘁𝗵𝗶𝗻𝗴:

💡 Decouples callers and handlers
 Endpoints send requests to MediatR instead of directly calling services or 
repositories.

💡 Centralized request dispatching
 MediatR routes each command or query to its matching handler.

💡 Pipeline behaviors
 Validation, logging, caching, and other cross-cutting concerns stay clean and reusable.

💡 Easy testing
 Handlers are isolated and focused, which makes them simple to test.

Together, CQRS and MediatR deliver:
1. High performance APIs
2. A clean and focused codebase
3. Flexible horizontal scaling
4. Clear mapping between application actions and logic

This structure typically includes command and query records, dedicated handlers, DTOs for read models, and minimal API endpoints that communicate through MediatR. 

Each action has one clear location and one responsibility.


P.S. If your system is growing, handling heavy read or write volumes, or struggling with performance and complexity, CQRS with MediatR can transform your architecture.


Would you use this approach in your next project? 👇
