* Postgres version 14 as Primary Database
* Redis for publishing data

### Installation

* Make sure you have golang version 1.20
* Make sure you have postgres that support uuid, jsonb
* Make sure you have installed redis
* See Recommmended project structure section.

### Migrate Database

Make sure you already create database and integrate with uuid extension. Look at [this](https://dba.stackexchange.com/questions/153017/how-do-i-install-enable-the-uuid-ossp-extension-on-postgres-9-3) to create uuid extension. Look at folder **internal/sqls** you can execute sql in that folder to migrate database.

Besides executing the commands above, you can execute the command below to migrate database. But before you execute migrate command, make sure you already set database environment in **.env** file

<pre class="language-go"><code class="lang-go"><strong>    go mod download // run this if dependency not downloaded
</strong>    go mod tidy // run this if dependency changed
    go run cmd/main.go -command=migrate:up // execute migration up will create tables
</code></pre>

There are 3 migrate commands :

* command `migrate:up` will create tables
* command `migrate:down` will drop tables
* command `migrate:both` will drop and then create tables

### Run Services

First to run this services, make sure your database and the tables that needed already created. Then create **.env** file from **example.env** template. The **example.env** file look likes below change the configuration and match with your environment.
