Maintained for backwards compatibility. - * @param {String} [options.pass] password for authentication, equivalent to `options.auth.password`. Maintained for backwards compatibility. - * @param {Number} [options.poolSize=5] The maximum number of sockets the MongoDB driver will keep open for this connection. By default, `poolSize` is 5. Keep in mind that, as of MongoDB 3.4, MongoDB only allows one operation per socket at a time, so you may want to increase this if you find you have a few slow queries that are blocking faster queries from proceeding. See [Slow Trains in MongoDB and Node.js](http://thecodebarbarian.com/slow-trains-in-mongodb-and-nodejs). - * @param {Boolean} [options.useUnifiedTopology=false] False by default. Set to `true` to opt in to the MongoDB driver's replica set and sharded cluster monitoring engine. - * @param {Number} [options.serverSelectionTimeoutMS] If `useUnifiedTopology = true`, the MongoDB driver will try to find a server to send any given operation to, and keep retrying for `serverSelectionTimeoutMS` milliseconds before erroring out. If not set, the MongoDB driver defaults to using `30000` (30 seconds). - * @param {Number} [options.heartbeatFrequencyMS] If `useUnifiedTopology = true`, the MongoDB driver sends a heartbeat every `heartbeatFrequencyMS` to check on the status of the connection. A heartbeat is subject to `serverSelectionTimeoutMS`, so the MongoDB driver will retry failed heartbeats for up to 30 seconds by default. Mongoose only emits a `'disconnected'` event after a heartbeat has failed, so you may want to decrease this setting to reduce the time between when your server goes down and when Mongoose emits `'disconnected'`. We recommend you do **not** set this setting below 1000, too many heartbeats can lead to performance degradation. - * @param {Boolean} [options.autoIndex=true] Mongoose-specific option. Set to false to disable automatic index creation for all models associated with this connection. - * @param {Boolean} [options.useNewUrlParser=false] False by default. Set to `true` to opt in to the MongoDB driver's new URL parser logic. - * @param {Boolean} [options.useCreateIndex=false] Mongoose-specific option. If `true`, this connection will use [`createIndex()` instead of `ensureIndex()`](/docs/deprecations.html#ensureindex) for automatic index builds via [`Model.init()`](/docs/api.html#model_Model.init). - * @param {Boolean} [options.useFindAndModify=true] True by default. Set to `false` to make `findOneAndUpdate()` and `findOneAndRemove()` use native `findOneAndUpdate()` rather than `findAndModify()`. - * @param {Number} [options.reconnectTries=30] If you're connected to a single server or mongos proxy (as opposed to a replica set), the MongoDB driver will try to reconnect every `reconnectInterval` milliseconds for `reconnectTries` times, and give up afterward. When the driver gives up, the mongoose connection emits a `reconnectFailed` event. This option does nothing for replica set connections. - * @param {Number} [options.reconnectInterval=1000] See `reconnectTries` option above. - * @param {Class} [options.promiseLibrary] Sets the [underlying driver's promise library](http://mongodb.github.io/node-mongodb-native/3.1/api/MongoClient.html). - * @param {Number} [options.bufferMaxEntries] This option does nothing if `useUnifiedTopology` is set. The MongoDB driver also has its own buffering mechanism that kicks in when the driver is disconnected. Set this option to 0 and set `bufferCommands` to `false` on your schemas if you want your database operations to fail immediately when the driver is not connected, as opposed to waiting for reconnection. - * @param {Number} [options.connectTimeoutMS=30000] How long the MongoDB driver will wait before killing a socket due to inactivity _during initial connection_. Defaults to 30000. This option is passed transparently to [Node.js' `socket#setTimeout()` function](https://nodejs.org/api/net.html#net_socket_settimeout_timeout_callback). - * @param {Number} [options.socketTimeoutMS=30000] How long the MongoDB driver will wait before killing a socket due to inactivity _after initial connection_. A socket may be inactive because of either no activity or a long-running operation. This is set to `30000` by default, you should set this to 2-3x your longest running operation if you expect some of your database operations to run longer than 20 seconds. This option is passed to [Node.js `socket#setTimeout()` function](https://nodejs.org/api/net.html#net_socket_settimeout_timeout_callback) after the MongoDB driver successfully completes. - * @param {Number} [options.family=0] Passed transparently to [Node.js' `dns.lookup()`](https://nodejs.org/api/dns.html#dns_dns_lookup_hostname_options_callback) function. May be either `0, `4`, or `6`. `4` means use IPv4 only, `6` means use IPv6 only, `0` means try both. - * @param {Boolean} [options.autoCreate=false] Set to `true` to make Mongoose automatically call `createCollection()` on every model created on this connection. - * @param {Function} [callback] - * @returns {Connection} this - * @api public - */ - - Connection.prototype.openUri = function (uri, options, callback) { - if (typeof options === "function") { - callback = options; - options = null; - } - - if (["string", "number"].indexOf(typeof options) !== -1) { - throw new MongooseError( - "Mongoose 5.x no longer supports " + - "`mongoose.connect(host, dbname, port)` or " + - "`mongoose.createConnection(host, dbname, port)`.

By default, `poolSize` is 5. Keep in mind that, as of MongoDB 3.4, MongoDB only allows one operation per socket at a time, so you may want to increase this if you find you have a few slow queries that are blocking faster queries from proceeding. See [Slow Trains in MongoDB and Node.js](http://thecodebarbarian.com/slow-trains-in-mongodb-and-nodejs). - * @param {Number} [options.bufferMaxEntries] This option does nothing if `useUnifiedTopology` is set. The MongoDB driver also has its own buffering mechanism that kicks in when the driver is disconnected. Set this option to 0 and set `bufferCommands` to `false` on your schemas if you want your database operations to fail immediately when the driver is not connected, as opposed to waiting for reconnection. - * @param {Number} [options.connectTimeoutMS=30000] How long the MongoDB driver will wait before killing a socket due to inactivity _during initial connection_.

A socket may be inactive because of either no activity or a long-running operation. This is set to `30000` by default, you should set this to 2-3x your longest running operation if you expect some of your database operations to run longer than 20 seconds.

A heartbeat is subject to `serverSelectionTimeoutMS`, so the MongoDB driver will retry failed heartbeats for up to 30 seconds by default. Mongoose only emits a `'disconnected'` event after a heartbeat has failed, so you may want to decrease this setting to reduce the time between when your server goes down and when Mongoose emits `'disconnected'`. We recommend you do **not** set this setting below 1000, too many heartbeats can lead to performance degradation. - * @param {Boolean} [options.autoIndex=true] Mongoose-specific option.

Set to `true` to opt in to the MongoDB driver's new URL parser logic. - * @param {Boolean} [options.useCreateIndex=true] Mongoose-specific option. If `true`, this connection will use [`createIndex()` instead of `ensureIndex()`](/docs/deprecations.html#ensureindex) for automatic index builds via [`Model.init()`](/docs/api.html#model_Model.init). - * @param {Boolean} [options.useFindAndModify=true] True by default. Set to `false` to make `findOneAndUpdate()` and `findOneAndRemove()` use native `findOneAndUpdate()` rather than `findAndModify()`. - * @param {Number} [options.reconnectTries=30] If you're connected to a single server or mongos proxy (as opposed to a replica set), the MongoDB driver will try to reconnect every `reconnectInterval` milliseconds for `reconnectTries` times, and give up afterward. When the driver gives up, the mongoose connection emits a `reconnectFailed` event. This option does nothing for replica set connections. - * @param {Number} [options.reconnectInterval=1000] See `reconnectTries` option above. - * @param {Class} [options.promiseLibrary] Sets the [underlying driver's promise library](http://mongodb.github.io/node-mongodb-native/3.1/api/MongoClient.html). - * @param {Number} [options.bufferMaxEntries] This option does nothing if `useUnifiedTopology` is set. The MongoDB driver also has its own buffering mechanism that kicks in when the driver is disconnected. Set this option to 0 and set `bufferCommands` to `false` on your schemas if you want your database operations to fail immediately when the driver is not connected, as opposed to waiting for reconnection. - * @param {Number} [options.connectTimeoutMS=30000] How long the MongoDB driver will wait before killing a socket due to inactivity _during initial connection_. Defaults to 30000. This option is passed transparently to [Node.js' `socket#setTimeout()` function](https://nodejs.org/api/net.html#net_socket_settimeout_timeout_callback). - * @param {Number} [options.socketTimeoutMS=30000] How long the MongoDB driver will wait before killing a socket due to inactivity _after initial connection_. A socket may be inactive because of either no activity or a long-running operation. This is set to `30000` by default, you should set this to 2-3x your longest running operation if you expect some of your database operations to run longer than 20 seconds. This option is passed to [Node.js `socket#setTimeout()` function](https://nodejs.org/api/net.html#net_socket_settimeout_timeout_callback) after the MongoDB driver successfully completes. - * @param {Number} [options.family=0] Passed transparently to [Node.js' `dns.lookup()`](https://nodejs.org/api/dns.html#dns_dns_lookup_hostname_options_callback) function. May be either `0`, `4`, or `6`. `4` means use IPv4 only, `6` means use IPv6 only, `0` means try both. - * @param {Boolean} [options.autoCreate=false] Set to `true` to make Mongoose automatically call `createCollection()` on every model created on this connection. - * @param {Function} [callback] - * @see Mongoose#createConnection #index_Mongoose-createConnection - * @api public - * @return {Promise} resolves to `this` if connection succeeded - */ - - Mongoose.prototype.connect = function (uri, options, callback) { - const _mongoose = this instanceof Mongoose ?

Overrides the [schema-level write concern](/docs/guide.html#writeConcern) - * - `omitUndefined` (boolean): If true, delete any properties whose value is `undefined` when casting an update. In other words, if this is set, Mongoose will delete `baz` from the update in `Model.updateOne({}, { foo: 'bar', baz: undefined })` before sending the update to the server. - * - `multi` (boolean): whether multiple documents should be updated (false) - * - `runValidators`: if true, runs [update validators](/docs/validation.html#update-validators) on this command. Update validators validate the update operation against the model's schema. - * - `setDefaultsOnInsert` (boolean): if this and `upsert` are true, mongoose will apply the [defaults](http://mongoosejs.com/docs/defaults.html) specified in the model's schema if a new document is created. This option only works on MongoDB >= 2.4 because it relies on [MongoDB's `$setOnInsert` operator](https://docs.mongodb.org/v2.4/reference/operator/update/setOnInsert/). - * - `timestamps` (boolean): If set to `false` and [schema-level timestamps](/docs/guide.html#timestamps) are enabled, skip timestamps for this update. Does nothing if schema-level timestamps are not set. - * - `overwrite` (boolean): disables update-only mode, allowing you to overwrite the doc (false) - * - * All `update` values are cast to their appropriate SchemaTypes before being sent. - * - * The `callback` function receives `(err, rawResponse)`. - * - * - `err` is the error if any occurred - * - `rawResponse` is the full response from Mongo - * - * ####Note: - * - * All top level keys which are not `atomic` operation names are treated as set operations: - * - * ####Example: - * - * const query = { name: 'borne' }; - * Model.update(query, { name: 'jason bourne' }, options, callback); - * - * // is sent as - * Model.update(query, { $set: { name: 'jason bourne' }}, options, function(err, res)); - * // if overwrite option is false.

Use this option to make `populate()` retain `null` and `undefined` array entries. - * @param {boolean} [options.getters=false] If true, Mongoose will call any getters defined on the `localField`. By default, Mongoose gets the raw value of `localField`. For example, you would need to set this option to `true` if you wanted to [add a `lowercase` getter to your `localField`](/docs/schematypes.html#schematype-options). - * @param {boolean} [options.clone=false] When you do `BlogPost.find().populate('author')`, blog posts with the same author will share 1 copy of an `author` doc. Enable this option to make Mongoose clone populated docs before assigning them. - * @param {Object|Function} [options.match=null] Add an additional filter to the populate query. Can be a filter object containing [MongoDB query syntax](https://docs.mongodb.com/manual/tutorial/query-documents/), or a function that returns a filter object. - * @param {Boolean} [options.skipInvalidIds=false] By default, Mongoose throws a cast error if `localField` and `foreignField` schemas don't line up. If you enable this option, Mongoose will instead filter out any `localField` properties that cannot be casted to `foreignField`'s schema type. - * @param {Number} [options.perDocumentLimit=null] For legacy reasons, `limit` with `populate()` may give incorrect results because it only executes a single query for every document being populated. If you set `perDocumentLimit`, Mongoose will ensure correct `limit` per document by executing a separate query for each document to `populate()`. For example, `.find().populate({ path: 'test', perDocumentLimit: 2 })` will execute 2 additional queries if `.find()` returns 2 documents. - * @param {Object} [options.options=null] Additional options like `limit` and `lean`. - * @param {Function} [options.transform=null] Function that Mongoose will call on every populated document that allows you to transform the populated document. - * @param {Function} [callback(err,doc)] Optional callback, executed upon completion.

Async validators run in - * parallel, and `validate()` will wait until all async validators have settled. - * - * schema.path('name').validate({ - * validator: function (value) { - * return new Promise(function (resolve, reject) { - * resolve(false); // validation failed - * }); - * } - * }); - * - * You might use asynchronous validators to retreive other documents from the database to validate against or to meet other I/O bound validation needs. - * - * Validation occurs `pre('save')` or whenever you manually execute [document#validate](#document_Document-validate). - * - * If validation fails during `pre('save')` and no callback was passed to receive the error, an `error` event will be emitted on your Models associated db [connection](#connection_Connection), passing the validation error object along. - * - * const conn = mongoose.createConnection(..); - * conn.on('error', handleError); - * - * const Product = conn.model('Product', yourSchema); - * const dvd = new Product(..); - * dvd.save(); // emits error on the `conn` above - * - * If you want to handle these errors at the Model level, add an `error` - * listener to your Model as shown below. - * - * // registering an error listener on the Model lets us handle errors more locally - * Product.on('error', handleError); - * - * @param {RegExp|Function|Object} obj validator function, or hash describing options - * @param {Function} [obj.validator] validator function. If the validator function returns `undefined` or a truthy value, validation succeeds. If it returns [falsy](https://masteringjs.io/tutorials/fundamentals/falsy) (except `undefined`) or throws an error, validation fails. - * @param {String|Function} [obj.message] optional error message. If function, should return the error message as a string - * @param {Boolean} [obj.propsParameter=false] If true, Mongoose will pass the validator properties object (with the `validator` function, `message`, etc.) as the 2nd arg to the validator function. This is disabled by default because many validators [rely on positional args](https://github.com/chriso/validator.js#validators), so turning this on may cause unpredictable behavior in external validators. - * @param {String|Function} [errorMsg] optional error message.

For example, - // a zlib stream might take multiple plain-text writes(), and then - // emit a single compressed chunk some time in the future. - // - // Here's how this works: - // - // The Transform stream has all the aspects of the readable and writable - // stream classes. When you write(chunk), that calls _write(chunk,cb) - // internally, and returns false if there's a lot of pending writes - // buffered up. When you call read(), that calls _read(n) until - // there's enough pending readable data buffered up. - // - // In a transform stream, the written data is placed in a buffer. When - // _read(n) is called, it transforms the queued up data, calling the - // buffered _write cb's as it consumes chunks. If consuming a single - // written chunk would result in multiple output chunks, then the first - // outputted bit calls the readcb, and subsequent chunks just go into - // the read buffer, and will cause it to emit 'readable' if necessary. - // - // This way, back-pressure is actually determined by the reading side, - // since _read has to be called to start processing a new chunk. However, - // a pathological inflate type of transform can cause excessive buffering - // here. For example, imagine a stream where every byte of input is - // interpreted as an integer from 0-255, and then results in that many - // bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in - // 1kb of data being output. In this case, you could write a very small - // amount of input, and end up with a very large amount of output. In - // such a pathological inflating mechanism, there'd be no way to tell - // the system to stop doing the transform. A single 4MB write could - // cause the system to run out of memory. - // - // However, even in such a pathological case, only a single written chunk - // would be consumed, and then the rest would wait (un-transformed) until - // the results of the previous transformed chunk were consumed. - - module.exports = Transform; - - var Duplex = __nccwpck_require__(1359); - - /**/ - var util = Object.create(__nccwpck_require__(5898)); - util.inherits = __nccwpck_require__(4124); - /**/ - - util.inherits(Transform, Duplex); - - function afterTransform(er, data) { - var ts = this._transformState; - ts.transforming = false; - - var cb = ts.writecb; - - if (!cb) { - return this.emit( - "error", - new Error("write callback called multiple times") - ); - } +/** + * Issues a mongodb [findAndModify](http://www.mongodb.org/display/DOCS/findAndModify+Command) remove command. + * + * Finds a matching document, removes it, passing the found document (if any) to the callback.
