docker-compose up --build

Check http://localhost:8080

sudo apt update
sudo apt upgrade
# See last version here: https://golang.org/dl/
wget https://dl.google.com/go/go1.12.5.linux-amd64.tar.gz
sudo tar -xvf go1.12.5.linux-amd64.tar.gz
sudo mv go /usr/local
sudo mcedit /etc/profile

And add last line:

export PATH=$PATH:/usr/local/go/bin

Update environment variables:

source /etc/profile

Check Go version:

go version

Now create folder for Go projects:

mkdir ~/go
cd ~/go
touch init.sh
mcedit init.sh

Paste next code into this file:

#!/bin/bash

export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin

Execute file:

chmod +x init.sh
source init.sh

git clone git@github.com:zubroide/go-api-boilerplate.git
cd go-api-boilerplate

./install/install.sh

cp .env.example .env
mcedit .env

go mod download

Create database go-api-boilerplate.

And run migrations:

make migrate

make server

Or:

go run main.go server --port=8080

Check http://localhost:8080

Run all tests:

go test ./... -v -coverpkg=./... -coverprofile=coverage.out
go tool cover -html=coverage.out

Run test for one package:

go test go-api-boilerplate/test/unit -v -coverpkg=./... -coverprofile=coverage.out

Run one test:

go test test/unit/user_service_test.go -v -coverpkg=./... -coverprofile=coverage.out

Using make:

make test

Generate swagger.json:

make swagger

Documentation must be available at url http://localhost:8080/swagger/index.html
