# The simplest RxJS wrapper around grpc lib

[![Build Status](https://travis-ci.com/ihoro/rough-rx-grpc.svg?branch=master)](https://travis-ci.com/ihoro/rough-rx-grpc)

[![npm version](https://badge.fury.io/js/%40rough%2Frx-grpc.svg)](https://badge.fury.io/js/%40rough%2Frx-grpc)

Rough implementation of [rxified](https://npmjs.com/rxjs) wrapper and tools for [grpc-js](https://www.npmjs.com/package/@grpc/grpc-js) lib.

## Usage example

```proto

// GreetingService.proto

syntax = "proto3";

package org.example;

service GreetingService {

  rpc Greet(Request) returns (Response);

}

message Request {

  string name = 1;

}

message Response {

  string message = 1;

}

```

```js

// server.js

class GreetingService {

  Greet(call, callback) {

    const name = call.request.name;

    if (name)

      callback(null, { message: `Hello, ${name}!` });

    else

      callback(new Error('Name is not defined.'));

  }

}

const RxGrpc = require('@rough/rx-grpc');

new RxGrpc()

  .withProtoFiles(__dirname + '/*.proto')

  .serve('org.example.GreetingService', new GreetingService())

  .startServer()

  .subscribe(

    started => console.log('Listening at grpc://0.0.0.0:50051 ...'),

    err => console.log(err),

    complete => {}

  );

```

```js

// client.js

const { flatMap } = require('rxjs/operators');

const RxGrpc = require('@rough/rx-grpc');

const rxgrpc = new RxGrpc().withProtoFiles(__dirname + '/*.proto');

const name = (process.argv.length > 2) ? process.argv[2] : null;

rxgrpc.service('org.example.GreetingService', 'localhost:50051').pipe(

  flatMap(GreetingService => GreetingService.Greet({ name }))

)

.subscribe(

  response => console.log(response.message),

  err => console.log(err),

  complete => {}

);

```
