Welcome to grpc-json-mock 😀

Introduction

• A GRPC mock server for front-end development.
• Multiple APIs are supported.
• Supports the following APIs
  • unary
  • serverStreming
  • clientStreming
  • duplexStreming

Install

npm i -D grpc-json-mock

Cli

gen-grpc-tamplate

• By specifying a proto file, you can output a json template for use in mock.

node ./node_module/.bin/gen-grpc-template {path}

Parameter	Description
path	Set the directory where the proto file or proto file is located

• option

option	Description
-i	import another path

• e.g.

syntax = "proto3";
package helloworld;

service Greeter {
  rpc unary (UnaryRequest) returns (UnaryResponse) {}
  rpc serverStreaming (UnaryRequest) returns (stream UnaryResponse) {}
  rpc clientStreaming (stream UnaryRequest) returns (UnaryResponse) {}
  rpc duplexStreaming (stream UnaryRequest) returns (stream UnaryResponse) {}
}

message UnaryRequest {
  string name = 1;
}

message UnaryResponse {
  string message = 1;
}
