Understanding findByIdAndUpdate
- findByIdAndUpdate is a MongoDB operation that finds a single document by its unique _id field, updates it and returns either the original document by default or the modified document if specified.
- It is particularly useful when you have the _id of the document you want to update.
Syntax:
db.collection.findByIdAndUpdate(
<id>,
<update>,
{
returnOriginal: <boolean>,
// Additional options
}
);
Parameters:
- <id>: Specifies the unique _id of the document to be updated.
- <update>: Specifies the modifications to apply to the selected document.
- returnOriginal: Optional. Determines whether to return the original document (true) or the modified document (false). Default is true.
Difference Between findOneAndUpdate and findByIdAndUpdate in MongoDB
