node-grpc-health-check

Health check client and service for use with @grpc/grpc-js.

Background

This package exports both a client and server that adhere to the gRPC Health Checking Protocol.

Why not grpc-health-check

• grpc-health-check is for deprecated native grpc package not for @grpc/grpc-js
• grpc-health-check implements an expired protocol of gRPC Health Checking Protocol not the latest version

Features

• 100% Typescript
• implements the latest version of gRPC Health Checking Protocol
• API is similar to grpc-health-check
• support shutdown and resume method like grpc-go

Install

$ yarn add @zcong/node-grpc-health-check
# or npm
$ npm i @zcong/node-grpc-health-check --save

Server

import { HealthImplementation, service, ServingStatus } from '../src'

const server = new grpc.Server()
const h = new HealthImplementation({
  '': ServingStatus.NOT_SERVING,
  test1: ServingStatus.SERVING,
})
server.addService(service, h)

Client

Any gRPC-node client can use @zcong/node-grpc-health-check to run health checks against other servers that follow the protocol.
