How to use the set function from mongoose

Find comprehensive JavaScript mongoose.set code examples handpicked from public code repositorys.

Mongoose.set is a function that allows you to configure global settings for a Mongoose instance, such as the use of native promises or automatic indexing.

How does mongoose.set work?

mongoose.set works by taking two inputs: a setting name and a value to set for that setting.

The function sets a global setting for the Mongoose instance, affecting all schemas and models defined within that instance.

Some of the settings that can be configured include the use of native promises, automatic indexing, and strict mode.

For example, calling mongoose.set('useFindAndModify', false) disables the use of the deprecated findOneAndUpdate function and uses the new updateOne function instead.

By configuring global settings using mongoose.set, you can control the behavior of Mongoose and ensure that all schemas and models behave consistently within your application.

const mongoose = require("mongoose");

// Set the useFindAndModify option to false
mongoose.set("useFindAndModify", false);

// Define a Mongoose schema
const UserSchema = new mongoose.Schema({
  name: String,
  email: String,
});

// Create a Mongoose model from the schema
const User = mongoose.model("User", UserSchema);

// Update a user using the findOneAndUpdate method
User.findOneAndUpdate(
  { name: "John" },
  { email: "john@example.com" },
  (err, user) => {
    if (err) {
      console.error(err);
    } else {
      console.log("User updated:", user);
    }
  }
);

// Update a user using the updateOne method
User.updateOne({ name: "John" }, { email: "john@example.com" }, (err, res) => {
  if (err) {
    console.error(err);
  } else {
    console.log("User updated:", res);
  }
});

In this example, we use mongoose.set to configure the global useFindAndModify setting for the Mongoose instance to false. We then define a Mongoose schema for a user with a name and email field, and create a Mongoose model from the schema. We then update a user using both the deprecated findOneAndUpdate method and the new updateOne method. Since we have set useFindAndModify to false, the first update operation will use the new updateOne method instead of findOneAndUpdate, while the second operation will use updateOne directly. By using mongoose.set, we have ensured that all update operations within our Mongoose instance use the latest and recommended method.
