Product Service

Product Service is an implementation of services communication via gRPC and HTTP requests. Some technologies used here are Golang, Node.JS, gRPC, PostgreSQL, Docker and Docker Compose and many others.

These services were designed according to Hash's hiring test. To understand each service and its technical decisions, please access each service's README:

• Product
• Discount

Project structure

• discount: service 1 implementation, written in Node.JS
• migrations: contains the database migration scripts and it's used along golang-migrate
• product: service 2 implementation, written in Golang
• protos: contains the protobuf scripts and generated code for gRPC communication

Installation

Install docker and docker-compose and build the images.

docker-compose build

Usage

Export the necessary environment variables (hint: save them to a .env file and run export $(xargs <.env)). Below there are a few to get you started:

DB_USER=larien
DB_HOST=database
DB_PORT=5432
DB_NAME=product
DB_PASSWORD=lauren123
LOG_LEVEL=1
PORT=:8080
POSTGRESQL_URL=postgres://larien:lauren123@database:5432/product?sslmode=disable
GRPC_PORT=:50051
GRPC_HOST=0.0.0.0

Run the built images (include -d if you don't want to read the logs in your terminal)

docker-compose up --remove-orphans

Tips and tricks

Connecting to the database inside the container

docker exec -it database bash
su - postgres
psql -p 5432 -d <database-name> -U <user-name>

Happy inserting!
