gRPC Reflection

gRPC reflection API service for use with gRPC-node.

Background

This package provides an implementation of the gRPC Server Reflection Protocol service which can be added to an existing gRPC server. Adding this service to your server will allow clients such as postman to dynamically load the API specification from your running application rather than needing to pass around and load proto files manually.

Installation

Use the package manager npm to install @grpc/reflection.

npm install @grpc/reflection

Usage

Any gRPC-node server can use @grpc/reflection to expose reflection information about their gRPC API.

import { ReflectionService } from '@grpc/reflection';

const pkg = protoLoader.load(...); // Load your gRPC package definition as normal

// Create the reflection implementation based on your gRPC package and add it to your existing server
const reflection = new ReflectionService(pkg);
reflection.addToServer(server);

Congrats! Your server now allows any client to request reflection information about its API.
