HOW TO INSTALL

go get github.com/meongbego/bgin

Test in Running

go run main.go

Test Build

go build main.go

To run production

go run main.go -e production or ./build -e production

ENVIRONMENT SETUP

LOCAL DEVELOPMENT ENV

if using local development use .env file

cp .env.example .env

now setup your env

PRODUCTION

if production mode environtment setup in os env, example in your terminal execute this script

export GIN_MODE=release
export APP_PORT=5000
export APP_HOST=0.0.0.0
export DB_HOST=roach1
export DB_PORT=26257
export DB_NAME=bgin
export DB_USER=root
export DB_PASSWORD=
export ACL_ADDR=172.19.0.0/24
export REDIS_HOST=rdcaches
export REDIS_PORT=6379
export KAFKA_HOST_PORT=localhost:9092

if your production dockerizing see docker-compose.yml to export environtment

PACKAGE

Activate and deactivate available packages see on app/moduls/package, see the example on main.go

main.go

look at this line:

db.Conn = db.Init()
db.MigrateScheme(db.Conn)
redis.Store = redis.Init()

Package:

1. kafka
2. elasticsearch
3. etcd
4. database (cockroachdb)
5. redis

DATABASE SCHEME AN IMPORTED TABLE

to create a database schema look at the app/moduls/migration/ folder then edit the schem.go file

app/moduls/migration/scheme.go

look at this line:

db.AutoMigrate (& LoginScheme {}, & Userdata {})

CONTROLLER

to create a controller schema look at the app/controller/api folder

app/controller/api

ROUTES

to create route in look at app/controller folder then edit routes.go

app/controller/routes.go

look at this line:

api := router.Group("api")
{
    ping := new(controller.PingController)
    health := new(controller.HealthController)
    login := new(controller.LoginController)
    // create rest api models
    api.GET("/ping", ping.Status)
    api.GET("/health", health.Status)
    api.POST("/login", login.LoginUsers)
    api.GET("/login/list", login.ListLogin)
}

MODELS

to create a models look at the app/models folder

app/models/

see loginModels.go for examples

DEVELOPMENT MODE

To activate Live Reload install air

on macOS

curl -fLo /usr/local/bin/air \
    https://raw.githubusercontent.com/cosmtrek/air/master/bin/darwin/air
chmod +x /usr/local/bin/air

on Linux

curl -fLo /usr/local/bin/air \
    https://raw.githubusercontent.com/cosmtrek/air/master/bin/linux/air
chmod +x /usr/local/bin/air

on Windows

curl -fLo ~/air.exe \
    https://raw.githubusercontent.com/cosmtrek/air/master/bin/windows/air.exe

see watcher.conf setting watcher file for air config now

Starting

go to your project path

air -c watcher.conf

DOCKERIZING

if you dockerizing this project follow this step

docker build -t your_tagging .

then see docker-compose.yml edit file for your configuration and install docker-compose for execute this script

version: '3'
services:
  rdcaches:
    image: redis
    command: ["redis-server"]
    ports:
      - "6379:6379"

  roach1:
    image: cockroachdb/cockroach
    command: start --insecure
    ports:
      - "26257:26257"
      - "8080:8080"
    volumes:
      - ./cockroach-data/roach1:/cockroach/cockroach-data

  roach2:
    image: cockroachdb/cockroach
    command: start --insecure --join=roach1
    volumes:
      - ./cockroach-data/roach2:/cockroach/cockroach-data
    links:
      - roach1
  
  bgin:
    image: your_tagging
    ports:
      - "6968:5000"
    environment:
      - GIN_MODE=release
      - APP_PORT=5000
      - APP_HOST=0.0.0.0
      - DB_HOST=roach1
      - DB_PORT=26257
      - DB_NAME=bgin
      - DB_USER=root
      - DB_PASSWORD=
      - ACL_ADDR=172.19.0.0/24
      - REDIS_HOST=rdcaches
      - REDIS_PORT=6379
    command: ./main -e production
    links:
      - roach1
      - rdcaches

then start compose

docker-compose up

stop container

docker-compose stop; docker-compose rm -f
