# NestJS + gRPC: a multi microservices example
This repo show as to configure a multi microservices stack in NestJS using gRPC in docker environment.
## Docker Stack
- 3 NestJS microservices
- 1 NestJS client
- 1 Prisma server
- 1 DB MySQL
## Run it!
```bash
make init
docker-compose up
```
Navigate to
```
http://localhost:3000/test/client1
http://localhost:3000/test/client2
http://localhost:3000/test/client_prisma_add
http://localhost:3000/test/client_prisma_get
```
## Protobuf (*.proto) builder
This project use ts-proto library to generate interfaces from *.proto files.
Just add/edit some proto file into proto folder, then run:
```sh
make proto_build
```
For example, this proto file:
```protobuf
syntax = "proto3";
import "google/protobuf/empty.proto";
package micr_prisma;
service MicrService {
rpc FindOne (google.protobuf.Empty) returns (UserList) {}
rpc Save (google.protobuf.Empty) returns (User) {}
}
message User {
string id = 1;
string name = 2;
string surname = 3;
}
message UserList {
repeated User users = 1;
}
```
generate the following typescript code:
```ts
/* eslint-disable */
import { Empty } from './google/protobuf/empty';
export interface User {
id: string;
name: string;
surname: string;
}
export interface UserList {
users: User[];
}
export interface MicrService {
FindOne(request: Empty): Promise;
Save(request: Empty): Promise;
}
```
We can use these interfaces in NestJS project easily.
