MangooseJS - Javascript

MangooseJS is a JavaScript library that provides an easy and efficient way to work with databases using the MongoDB database management system. It offers a simplified and intuitive interface for interacting with MongoDB, allowing developers to focus on building their applications rather than dealing with the complexities of database management.

Features

• Schema-based Modeling: MangooseJS provides a schema-based modeling approach to define the structure of your data. You can define schemas with properties and their data types, validation rules, and default values.

• Easy Querying: With MangooseJS, you can perform CRUD (Create, Read, Update, Delete) operations on MongoDB collections using a straightforward API. It supports various querying methods to filter and sort data based on your requirements.

• Data Population: MangooseJS supports data population, which allows you to automatically populate referenced documents from other collections, making it easier to retrieve and work with related data.

• Middleware Support: Middleware functions can be added to perform actions before or after specific events, such as saving a document, updating a document, or removing a document. This enables you to add custom logic to handle certain operations.

• Validation: MangooseJS provides built-in validation capabilities to ensure data integrity. You can define specific validation rules and error messages for each property in your schema, helping you maintain data consistency.

Code Example

Here is an example of how MangooseJS can be used to define a simple schema, create a model, and perform basic CRUD operations:

const mongoose = require('mongoose');

// Define a schema
const userSchema = new mongoose.Schema({
  name: {
    type: String,
    required: true
  },
  email: {
    type: String,
    required: true,
    unique: true
  },
  age: {
    type: Number,
    default: 18
  }
});

// Create a model
const User = mongoose.model('User', userSchema);

// Insert a new user
const newUser = new User({
  name: 'John Doe',
  email: 'john@example.com',
  age: 25
});

newUser.save()
  .then(user => {
    console.log('User saved: ', user);
  })
  .catch(error => {
    console.error('Error saving user: ', error);
  });

// Retrieve users
User.find()
  .then(users => {
    console.log('Users: ', users);
  })
  .catch(error => {
    console.error('Error retrieving users: ', error);
  });

// Update a user
User.findOneAndUpdate({ name: 'John Doe' }, { age: 30 })
  .then(updatedUser => {
    console.log('Updated user: ', updatedUser);
  })
  .catch(error => {
    console.error('Error updating user: ', error);
  });

// Delete a user
User.findOneAndRemove({ name: 'John Doe' })
  .then(deletedUser => {
    console.log('Deleted user: ', deletedUser);
  })
  .catch(error => {
    console.error('Error deleting user: ', error);
  });
