* #### Example:
|
|
*
|

* // setting schema options
|

* new Schema({ name: String }, { _id: false, autoIndex: false })
|
|
*
|
|
* #### Options:
|
|
*
|
|
* - [autoIndex](/docs/guide.html#autoIndex): bool - defaults to null (which means use the connection's autoIndex option)
|
|
* - [autoCreate](/docs/guide.html#autoCreate): bool - defaults to null (which means use the connection's autoCreate option)
|
|
* - [bufferCommands](/docs/guide.html#bufferCommands): bool - defaults to true
|
|
* - [bufferTimeoutMS](/docs/guide.html#bufferTimeoutMS): number - defaults to 10000 (10 seconds). If `bufferCommands` is enabled, the amount of time Mongoose will wait for connectivity to be restablished before erroring out.
|
|
* - [capped](/docs/guide.html#capped): bool | number | object - defaults to false
|
|
* - [collection](/docs/guide.html#collection): string - no default
|
|
* - [discriminatorKey](/docs/guide.html#discriminatorKey): string - defaults to `__t`
|
|
* - [id](/docs/guide.html#id): bool - defaults to true
|
|
* - [_id](/docs/guide.html#_id): bool - defaults to true
|
|
* - [minimize](/docs/guide.html#minimize): bool - controls [document#toObject](#document_Document-toObject) behavior when called manually - defaults to true
|
|
* - [read](/docs/guide.html#read): string
|
|
* - [writeConcern](/docs/guide.html#writeConcern): object - defaults to null, use to override [the MongoDB server's default write concern settings](https://www.mongodb.com/docs/manual/reference/write-concern/)
|
|
* - [shardKey](/docs/guide.html#shardKey): object - defaults to `null`
|
|
* - [strict](/docs/guide.html#strict): bool - defaults to true
|
|
* - [strictQuery](/docs/guide.html#strictQuery): bool - defaults to false
|
|
* - [toJSON](/docs/guide.html#toJSON) - object - no default
|
|
* - [toObject](/docs/guide.html#toObject) - object - no default
|
|
* - [typeKey](/docs/guide.html#typeKey) - string - defaults to 'type'
|
|
* - [validateBeforeSave](/docs/guide.html#validateBeforeSave) - bool - defaults to `true`
|
|
* - [versionKey](/docs/guide.html#versionKey): string or object - defaults to "__v"
|
|
* - [optimisticConcurrency](/docs/guide.html#optimisticConcurrency): bool - defaults to false. Set to true to enable [optimistic concurrency](https://thecodebarbarian.com/whats-new-in-mongoose-5-10-optimistic-concurrency.html).
|
|
* - [collation](/docs/guide.html#collation): object - defaults to null (which means use no collation)
|
|
* - [timeseries](/docs/guide.html#timeseries): object - defaults to null (which means this schema's collection won't be a timeseries collection)

|
|
* - [skipVersioning](/docs/guide.html#skipVersioning): object - paths to exclude from versioning
|
|
* - [timestamps](/docs/guide.html#timestamps): object or boolean - defaults to `false`. If true, Mongoose adds `createdAt` and `updatedAt` properties to your schema and manages those properties for you.
|
|
* - [pluginTags](/docs/guide.html#pluginTags): array of strings - defaults to `undefined`. If set and plugin called with `tags` option, will only apply that plugin to schemas with a matching tag.
|
|
*
|
|
* #### Options for Nested Schemas:
|
|
*
|
|
* - `excludeIndexes`: bool - defaults to `false`. If `true`, skip building indexes on this schema's paths.
|
|
*
|
|
* #### Note:
|
|
*
|
|
* _When nesting schemas, (`children` in the example above), always declare the child schema first before passing it into its parent._
