In a client-streaming RPC, the client sends a sequence of messages. It’s the most straightforward type of interaction in gRPC, somewhat analogous to a standard client/server HTTP interaction. The Unary RPC involves a single request from the client, resulting in a single response from the server. When using gRPC, four types of service methods are available, differing based on request or response type. Eventually, Google made the project open source as gRPC, which by now has enjoyed heavy adoption by organizations seeking to connect mobile and IoT devices and servers. Google initially built an RPC framework called Stubby to connect its own set of microservices. The result is the potential to interconnect previously orthogonal services. The only information that the two parties must share is a common understanding of how to communicate with each other-a standard protocol for request and response message structures. Likewise, the remote computer may know very little about the environment or intentions of the calling computer. The computer making the procedure call may know little to nothing about the procedure’s implementation on the remote computer. What many don’t know is that Insomnia is also a gRPC client.Ī Remote Procedure Call (RPC) is one computer’s execution of a procedure (think: function ) on another computer over a network. Most developers are familiar with Insomnia as a desktop application for API design and testing and an API client for making HTTP requests, with a powerful templating engine and support for plugins. Running a pre-built client for gRPC requests certainly beats implementing one from scratch.Įnter Insomnia. If you’re tasked with gRPC server development, you might be looking for a simple client to test gRPC requests against your server. Whether you’re fully immersed in the world of gRPC development or just diving in now, you’re sure to recognize the power and simplicity of this cross-platform, language-neutral approach to connecting services across networks. If you’re already familiar with the basics, skip ahead to the tutorial or watch the video below.
