# [greenlock-store-sequelize](https://git.rootprojects.org/root/greenlock-store-sequelize.js) | A [Root](https://rootprojects.org) project

> A database-driven Greenlock storage plugin with wildcard support.

## Usage

To use, provide this Greenlock storage plugin as the `store` attribute when you
invoke `create`.

```js
greenlock.create({
  store: require('le-store-sequelize')
});
```

## Configuration

### Defaults

No configuration is required. By default, you'll get a baked-in Sequelize
database running [sqlite3](https://www.npmjs.com/package/sqlite3).

### Database Connection

Without `config.dbOptions`, the baked-in sequelize object uses sqlite3 with
defaults. If `config.dbOptions` is provided, you can configure the database
connection per the Sequelize documentation.

If a dialect other than sqlite3 is used, dependencies will need to be
installed.

```javascript
greenlock.create({
  store: require('le-store-sequelize')({
    dbConfig: {
      username: 'mysqluser',
      password: 'mysqlpassword',
      database: 'mysqldatabase,
      host: '127.0.0.1',
      dialect: 'mysql'
    }
  })
});
```

The database can also be configured using an env variable.

```javascript
greenlock.create({
  store: require('greenlock-store-sequelize')({
    dbConfig: {
      use_env_variable: 'DB_URL'
    }
  })
});
```

### Custom Database Object

If you already have a Sequelize object, you can pass that in as `config.db`,
circumventing the baked-in database entirely.

```javascript
var db = require('./db'); // your db

greenlock.create({
  store: require('le-store-sequelize')({
    db
  })
});
```
