Let’s build an API with mongodb and express:

Here’s a table with some commonly used MongoDB commands and their corresponding functions in the Mongoose library, which is a popular Object-Document Mapping (ODM) library for Node.js that provides a more intuitive and powerful API for MongoDB:

MongoDB Command	Mongoose Function
db.createCollection()	N/A - Mongoose does not have a corresponding
db.collection.insertOne()	MyModel.create()
db.collection.insertMany()	MyModel.insertMany()
db.collection.find()	MyModel.find()
db.collection.findOne()	MyModel.findOne()
db.collection.updateOne()	MyModel.updateOne()
db.collection.updateMany()	MyModel.updateMany()
db.collection.deleteOne()	MyModel.deleteOne()

Note that MyModel refers to a Mongoose model that is created by defining a schema and compiling it into a model.

Here are some examples of using Mongoose functions:

Create a Mongoose model:

const mongoose = require('mongoose');

const userSchema = new mongoose.Schema({
  name: String,
  email: { type: String, unique: true },
  password: String
});

const User = mongoose.model('User', userSchema);`

Insert data into a collection:

const user = new User({ name: 'John Doe', email: 'john@example.com', password: 'password123' });
user.save();

Find data in a collection:

const users = await User.find({ name: 'John Doe' });
console.log(users);

Update data in a collection:

await User.updateOne({ name: 'John Doe' }, { password: 'newpassword123' });

Delete data from a collection:

await User.deleteOne({ name: 'John Doe' });
