large-scale synchronous communication between microservices.complex communication between different languages and environments.gRPC is open source and part of the Cloud Native Computing Foundation (CNCF) ecosystem. gRPC was introduced to refresh the existing Application Programming Interface (API) design methods using Protocol Buffers and HTTP/2. It is a framework that allows the server and the client transparent communication. GRPC (Remote Procedure Call by Google) is an open source remote procedure call system initially developed at Google in 2015. Twim cryptocurrency trading app developed by Surf What is gRPC At the end of the article, we’ll share our company’s experience with cryptocurrency app development and solutions we found to accelerate the speed of data flow, namely using gRPC-offered possibilities. In this article, we are going to tell whether gRPC and WebSocket are comparable, what are gRPC and WebSocket cons and pros and their use cases to help you choose the best option for your project. One of the aspects under discussion is a comparison of gRPC and WebSocket. GRPC is actively discussed in the developers’ community. It can be used for various scenarios such as connecting polyglot services in microservices architecture, generating client libraries, or connecting mobile devices and browser clients to back-end services. GRPC is a modern open-source high-performance Remote Procedure Call (RPC) framework that can run in any environment ranging from servers inside a large data center to your own tablet. 8.According to Statista, as of January 2022, gRPC is a second-popular mobile communication software development kit (SDK) among Android apps worldwide. Hence, we must use our wisdom coupled with knowledge in designing an efficient communication model. Like there are no silver bullets, we can't just expect to pick one to solve every problem. Nevertheless, the use of WebSocket and RESTful services over HTTP needs to be drawn from the requirements. These are the cases where client and server communication over RESTful services will find it difficult if not prohibitive. Additionally, WebSocket works well for scenarios where a message needs to be pushed to multiple clients simultaneously. Generalizing, WebSocket is more suitable for cases where a push-based and real-time communication defines the requirement more appropriately. But for newer client-side applications like a stock-price application which requires real-time updates from the server, it's much convenient to leverage WebSocket. Let's quickly understand how can we make a decision.įor the bulk of the scenario where occasional communication is required with the server like getting the record of an employee, it's still sensible to use REST service over HTTP/S. So they both have their place and their uses. It's important to remember that while WebSocket has emerged out of shortcomings in HTTP, it's not, in fact, a replacement of HTTP. Now, we have seen enough of RESTful service over HTTP and simple communication over WebSocket to form our opinion around them. That's pretty much it! Again, there's an HTML page in code repository to work with a user interface.Īlthough profound in its simplicity, defining production grade REST API can be much more extensive task! 6. We'll now configure the STOMP endpoints: class WebSocketMessageBrokerConfig implements WebSocketMessageBrokerConfigurer void registerStompEndpoints(StompEndpointRegistry registry) void configureMessageBroker(MessageBrokerRegistry config) " įinally, let's create a client in JavaScript: var request = new XMLHttpRequest() To use WebSocket in Spring Boot, we'll need the appropriate starter:
