> Mongoose helper for [Lad][], which is used as an alternative to the default `mongoose.connect()` for multiple connection management. See the [Forward Email][forward-email] codebase for further insight into setup.

## Install

> **Requires mongoose v6+ to be a dependency in your project.**

[npm][]:

```sh
npm install @ladjs/mongoose mongoose
```

## Usage

```js
const Mongoose = require('@ladjs/mongoose');
const { Schema } = require('mongoose');

(async () => {
const m = new Mongoose({
mongo: {
options: { heartbeatFrequencyMS: 100, serverSelectionTimeoutMS: 1000 }
}
});

const conn1 = await m.createConnection('mongodb://server-one.example.com/database-name').asPromise();
const conn2 = await m.createConnection('mongodb://server-two.example.com/database-name').asPromise();

const UserSchema = new Schema({ name: String });
const LogSchema = new Schema({ name: String });

const Users = conn1.model('Users', UserSchema);
const Logs = conn2.model('Logs', LogSchema);

// write to the server-one.example.com database
await Users.create({ name: 'test' });

// write to the server-two.example.com database
await Logs.create({ name: 'test' });
})();
```

Note that instances of this class `Mongoose` only have the method `createConnection`. It is not 1:1 with `mongoose` normal singleton.

You should use [@ladjs/graceful][lad-graceful] to manage process SIGHUP and graceful exits.

## Options

| Option | Type | Default | Description |
| -------------------------------- | ------------------------- | ------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `logger` | Object | `console` | Custom logger function, see [cabin][] or [axe][] as a default if desired. |
| `mongo` | Object | --- | See below `uri` and `options` properties. |
| `mongo.uri` | String | undefined | mongo connection URI
which is passed as the first argument to `mongoose.createConnection`
see [mongo options docs](https://docs.mongodb.com/drivers/node/current/fundamentals/connection/#connection-options) |
| `mongo.options` | Object | undefined | mongo connection options
which is passed as the second argument to `mongoose.createConnection`
see [mongo options docs](https://docs.mongodb.com/drivers/node/current/fundamentals/connection/#connection-options) |
| `bindEvents` | Boolean | `true` | Whether or not to bind default events to the Mongoose connection using provided `logger`. |
| `hideMeta` | String or `false` Boolean | `"hide_meta"` | Appends a `true` boolean property to a property with this value in logs, e.g. `console.log('mongoose disconnected', { hide_meta: true });` which is useful for preventing metadata object from being invoked as the second argument (this is meant for usage with [Cabin][] and [Axe][] and made for [Forward Email][forward-email]). If you pass a `false` value then this property will not get populated. |
