⚡ Get Started

Download the github.template-fabric.dapp-go project and move to root of project:

git clone https://github.com/ic-matcom/academic_certificate.dapp-go.git && cd academic_certificate.dapp-go 

🚀 Deployment ways (2 ways)

You can start the server in 2 ways, the first is using docker and docker-compose and the second is manually

📦 Docker way

You will need docker and docker-compose in your system.

To builds Docker image from Dockerfile, run:

docker build --no-cache --force-rm --tag app_restapi .

Use docker-compose to start the container:

docker-compose up

🔧 Manual way

Run:

go mod download
go mod vendor

If you make changes to the Endpoint you must generate Swagger API Spec:

Build:

go build

🌍 Environment variables

The environment variable is exported with the location of the server configuration file.

If you have 🐧Linux or 🍎Dash, run:

export SERVER_CONFIG=$PWD/conf/conf.yaml

but if it's the windows cmd, run:

set SERVER_CONFIG=%cd%/conf/conf.yaml

🏃🏽‍♂️ Start the server

Before it is recommended that you read more about the server configuration file in the section 👉🏾 .

Run the server:

./github.template-fabric.dapp-go

and visit the swagger docs:

http://localhost:7001/swagger/index.html

You can then authenticate and test the remaining endpoints.

🧪 Unit or End-To-End Testing

Run:

go test -v
