More recently, they re-wrote the Node.js package with pure JavaScript code and without a C++ add-on. Previously, the gRPC team offered the grpc package for Node.js developers by binding the C++ gRPC implementation with Node.js via the Node.js add-ons system.

#POSTMAN GRPC HOW TO#
In this tutorial, I will explain how to use gRPC in Node.js by building a practical communication system for three microservices. The gRPC framework sends binary messages between clients and servers with the Protobuf serialization technology via the HTTP/2 protocol. GRPC (aka Google RPC) offers a fully featured RPC framework for developers with implementations for almost all popular programming languages, including Node.js. We can use either a synchronous, request-response-based communication strategy or an asynchronous, event-based communication strategy for inter-microservice communication. The availability of third-party libraries, fully featured inbuilt APIs, and helpful developer tools make Node.js a good candidate for building microservices.Įven though microservices typically work as independent services, they can communicate with each other via various communication mechanisms. In web development, microservices are typically loosely coupled web services that web developers integrate through an API gateway. Nowadays, most developers select the microservices pattern for building their web backends to overcome issues in the traditional monolithic architecture.
