Uses `.env` to aquire credentials.
|Prop|Required| Default | Description |
| ------------ | ------------ | ------------ | ------------ |
|PG_USER| Required | | |
|PG_URL| Required | | |
|PG_DATABASE |Required | | |

## Usage

Using in 3 Steps

1. .env

```
PG_USER=postgres
PG_URL=localhost
PG_DATABASE=postgres
PG_PASSWORD=postgres
PG_SCHEMA=mercado_alencar
PG_LOG=true
```

2. Model
```javascript
const Model = require('@schirrel/pg-connection/Model');
class User extends Model{
constructor(args = {}){
super("USER");
this.addColumn('email', 'EMAIL');
this.addColumn('name', 'NAME');
this.addColumn('password', 'PASSWORD');
this.addColumn('active', 'ACTIVE', true);
this.setValues(args);
}
}

module.exports = User;
```

3. Repository
```javascript
const Repository = require('@schirrel/pg-connection/Repository');
const User = require('../models/User');

class UserRepository extends Repository{
constructor(){
super(User);
}
}

module.exports = UserRepository;
```

And thats it.

## TL;DR
### Model
- Used as `extends Model` at your model class
- Call `super("TABLE_NAME")` with your table name
- To add a columns `this.addColumn('email', 'EMAIL');`, it accepts a 3rd parameter as the default value.
- To set values of your constructor use ``this.setValues(args);``

### Repository
- Used as `extends Repository` at your repo class
- Call `super(YourClass);` with your class reference
- it already have built in: get(id), create(model), update(model),delete(id), list(), search(options)
