# [greenlock-store-sequelize][1]

> 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
var store = require('le-store-sequelize');

var gl = greenlock.create({
  store,
  approveDomains,
  ...
});
```

## Wildcards & AltNames

Working with wildcards and multiple altnames requires Greenlock `>= v2.7`.

To do so you must set `opts.subject` and `opts.domains` within the
`approvedomains()` callback.

`subject` refers to "the subject of the ssl certificate" as opposed to `domain`
which indicates "the domain servername used in the current request". For
single-domain certificates they're always the same, but for multiple-domain
certificates `subject` must be the name no matter what `domain` is receiving a
request. `subject` is used as part of the name of the file storage path where
the certificate will be saved (or retrieved).

`domains` should be the list of "altnames" on the certificate, which should
include the `subject`.

## Example

```javascript
function approveDomains() {
}
```
## Configuration

### Defaults

No configuration is required. By default, you'll get a baked-in Sequelize
database running sqlite3.

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

### Database Connection

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

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

greenlock.create({
  store,
  ...
});
```

The database can also be configured using an env variable.

```javascript
var store = require('le-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');

var store = require('le-store-sequelize')({
  db
});

greenlock.create({
  store,
  ...
});
```
