Getting Started

The service is a backend GraphQL API which is written in Golang. It uses gqlgen to create strongly typed GraphQL APIs and Entgo as a ORM in front of a PostGreSQL database.

Prerequisites

To start development server you need the following components on your local machine:

1. Golang (1.17)
2. PostGreSQL (10.0+) (optionally use Docker + Docker Compose build)

Development

With make

Make sure you have Docker running on your computer.

Additionally, make sure you have sourced the environment variables below. This can be done by putting the environment variables in a file .env, and sourcing the environment variables using source .env in your terminal.

To start development, simply run make in the project directory.

For more information, please read the Makefile or execute make help in the terminal.

Without make

To start a development server on your machine follow these steps:

1. Set local environment variables required to run the application:

   export POSTGRES_USER=admin
   export POSTGRES_PASSWORD=admin
   export POSTGRES_DB=a3s

2. Start your PostGreSQL server (docker-compose up psql)

3. Download Go dependencies with go mod download

4. Generate gqlgen code with go run github.com/99designs/gqlgen generate

5. Generate Ent entities with go generate ./ent

6. Migrate the Ent schema to your local PostGreSQL database with go run cmd/migrate.go

7. Start the server with go run cmd/main.go
