|  |  * Schema constructor. | ||
|  |  * | ||
|  |  * ####Example: | ||
|  |  * | ||
|  |  *     const child = new Schema({ name: String }); | ||
|  |  *     const schema = new Schema({ name: String, age: Number, children: [child] }); | ||

 | ||
|  |  *     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 - 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://docs.mongodb.com/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' | ||
|  |  * - [typePojoToMixed](/docs/guide.html#typePojoToMixed) - boolean - defaults to true. Determines whether a type set to a POJO becomes a Mixed path or a Subdocument | ||
|  |  * - [useNestedStrict](/docs/guide.html#useNestedStrict) - boolean - defaults to false | ||
|  |  * - [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) | ||
|  |  * - [selectPopulatedPaths](/docs/guide.html#selectPopulatedPaths): boolean - defaults to `true` | ||
|  |  * - [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. | ||
|  |  * - [storeSubdocValidationError](/docs/guide.html#storeSubdocValidationError): boolean - Defaults to true. If false, Mongoose will wrap validation errors in single nested document subpaths into a single validation error on the single nested subdoc's path. | ||
|  |  * | ||
|  |  * ####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._ | ||
