For anyone using the Node.js driver instead of Mongoose, you'll want to use <code>{returnOriginal:false}</code> instead of <code>{new:true}</code>.

So, "findOneAndUpdate" requires an option to return original document. And, the option is:

<h2>MongoDB shell</h2>

<code>{returnNewDocument: true}</code>

Ref: <a href="https://docs.mongodb.com/manual/reference/method/db.collection.findOneAndUpdate/" rel="noreferrer">https://docs.mongodb.com/manual/reference/method/db.collection.findOneAndUpdate/</a>

<h2>Mongoose</h2>

<code>{new: true}</code>

Ref: <a href="http://mongoosejs.com/docs/api.html#query_Query-findOneAndUpdate" rel="noreferrer">http://mongoosejs.com/docs/api.html#query_Query-findOneAndUpdate</a>

<h2>Node.js MongoDB Driver API:</h2>

<code>{returnOriginal: false}</code>

blocks|key|4464975|text|默认情况下，findOneAndUpdate返回原始文档。如果希望它返回修改后的文档，请将options对象{+new:+true+}传递给函数：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4464976|Cat.findOneAndUpdate({+age:+17+},+{+$set:+{+name:+"Naomi"+}+},+{+new:+true+},+function(err,+doc)+{

By default <a href="http://mongoosejs.com/docs/api.html#model_Model.findOneAndUpdate">findOneAndUpdate</a> returns the original document. If you want it to return the modified document pass an options object <code>{ new: true }</code> to the function:

<pre><code>Cat.findOneAndUpdate({ age: 17 }, { $set: { name: "Naomi" } }, { new: true }, function(err, doc) {

Mongoose maintainer here. You need to set the <code>new</code> option to <code>true</code> (or, equivalently, <code>returnOriginal</code> to <code>false</code>)

<pre><code>await User.findOneAndUpdate(filter, update, { new: true });

// Equivalent
await User.findOneAndUpdate(filter, update, { returnOriginal: false });
</code></pre>

If you want to return the altered document you need to set the option <code>{new:true}</code> API reference you can use <code>Cat.findOneAndUpdate(conditions, update, options, callback) // executes</code> 

Taken by the official Mongoose API <a href="http://mongoosejs.com/docs/api.html#findoneandupdate_findOneAndUpdate" rel="noreferrer">http://mongoosejs.com/docs/api.html#findoneandupdate_findOneAndUpdate</a> you can use the following parameters

<pre><code>A.findOneAndUpdate(conditions, update, options, callback) // executes
A.findOneAndUpdate(conditions, update, options) // returns Query
A.findOneAndUpdate(conditions, update, callback) // executes
A.findOneAndUpdate(conditions, update) // returns Query
A.findOneAndUpdate() // returns Query
</code></pre>

Another implementation thats is not expressed in the official API page and is what I prefer to use is the <code>Promise</code> base implementation that allow you to have <code>.catch</code> where you can deal with all your various error there.

<pre><code> let cat: catInterface = {
 name: "Naomi"
 };

 Cat.findOneAndUpdate({age:17}, cat,{new: true}).then((data) =&gt;{
 if(data === null){
 throw new Error('Cat Not Found');
 }
 res.json({ message: 'Cat updated!' })
 console.log("New cat data", data);
 }).catch( (error) =&gt; {
 /*
 Deal with all your errors here with your preferred error handle middleware / method
 */
 res.status(500).json({ message: 'Some Error!' })
 console.log(error);
 });
</code></pre>

Below shows the query for mongoose's <code>findOneAndUpdate</code>. Here <code>new: true</code> is used to get the updated doc and <code>fields</code> is used for specific fields to get.

eg. <code>findOneAndUpdate(conditions, update, options, callback)</code>

<pre><code>await User.findOneAndUpdate({
 "_id": data.id,
 }, { $set: { name: "Amar", designation: "Software Developer" } }, {
 new: true,
 fields: {

I have created this plugin if anyone need this functionality across the whole app and want to avoid repetition. Just use this as a <a href="https://mongoosejs.com/docs/plugins.html#global" rel="nofollow noreferrer">global plugin</a>

Below is my code

<pre><code>var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/test');

var Cat = mongoose.model('Cat', {
 name: String,
 age: {type: Number, default: 20},
 create: {type: Date, default: Date.now} 
});

Cat.findOneAndUpdate({age: 17}, {$set:{name:"Naomi"}},function(err, doc){
 if(err){
 console.log("Something wrong when updating data!");
 }

 console.log(doc);
});
</code></pre>

I already have some record in my mongo database and I would like to run this code to update name for which age is 17 and then print result out in the end of code.

However, why I still get same result from console(not the modified name) but when I go to mongo db command line and type "<code>db.cats.find();</code>". The result came with modified name.

Then I go back to run this code again and the result is modified.

My question is: If the data was modified, then why I still got original data at first time when console.log it.
