In layman terms, SSE is a Server Sent Event where the UI first initiates the call and requests for data, then the Server sends back the data to the caller (UI) when the data is available.
When an HTTP connection is made from the UI, the server holds the connection and responds back with the data when and ever it gets an event/data from the downstream APIs/sources.
Here we are going to discuss sending unidirectional asynchronous events to any web app using Spring. You can send unidirectional events using the SseEmitter class in Spring. There is already a popular solution available for sending bi-directional events using Websockets. Using WebSockets both server and clients can communicate with each other using bi-directional connections between client and server. SSE is only used for sending uni-directional events from the server to clients using the HTTP protocol.
Basic knowledge of Spring and java threading is required.
Steps involved in SSE ar:
The server can send multiple events before closing the connection. Messages sent by the server should be text-based and the message starts with a keyword followed by a colon(:) and then a string message. ‘data’ is a keyword which represents a message for a client.

The term “Event” is really overloaded. There are many different utilities that leverage events. Event Sourcing, Event Carried State Transfer, and Event Notifications. None of these are for the same purpose. When talking about an Event Based architecture, realize which one you’re using and for what purpose.

Event planning & management app is the generic term for a wide range of mobile app products that are used in the management of professional and academic conferences, trade exhibitions, conventions, and events such as Continuing Professional Development meetings.
Based on the number of hours invested, features, and technologies involved, you can determine a rough estimate of Event Planning or Management app development cost. Cost depends on various factors such as follows.
• Basic & Advance Features
• Technology used
• Chosen Platform (iOS & Android)
• The Location of the app development center
• Mobile App complexity
• Numbers of hours invested in Project
The cost to create such an app can be as high as the number of integrated technologies. However, an app with basic features is certain to cost somewhere around $10,000 to $35,000 for single platforms (Android or iOS). If you want to make an app for various platforms then the cost will be vary based on features, location, development team, etc factors.
Event Management apps streamline the entry process for events. Save your precious time for a smooth experience and devote time for more significant activities such as increasing revenue with a mobile app from AppClues Infotech, a top Events & Exhibitions App Development Company based in the USA and offer the best services across the world.
Save your time and money with their cost-effective mobile apps to easily collaborate with the participants of the events. Real-time chats help to carry out video conferencing with both the participants and the employees as well. Their mobile apps increase the efficiency of multiple events by sending important messages to the participants with a single click.
