- One-way Binding: Data flows from the component to the view using interpolation ({{}}) or property binding ([property]). It ensures the view reflects changes in the component but not vice versa.
- Two-way Binding: Syncs data both ways between the component and the view using [(ngModel)]. Changes in the view automatically update the component, and vice versa.

MongoDB Introduction & Installation
MongoDB is a NoSQL database that stores data in flexible, JSON-like documents. Install it from the official site, add it to system PATH, and start the server with mongod. Use mongo to open the shell and begin interacting with the database.
Create Database using Mongo Shell, About Collection and Document
Use use myDatabase to create or switch to a database in Mongo Shell. A collection is like a table and is created when you insert a document (record). Example: db.users.insertOne({ name: "Alice", age: 25 }).
MongoDB Cursor
A MongoDB cursor is an object that allows you to iterate over the results of a query. By default, find() returns a cursor: db.users.find(). Use methods like .forEach(), .toArray(), or cursor limits for data handling.
MongoDb Methods - Such as - insertOne(),insert(),insertMany(),update() etc.
MongoDB provides methods like insertOne(), insertMany() for adding documents, and updateOne(), updateMany() for modifying them. insert() is older and can insert one or more documents. Use deleteOne(), deleteMany(), and find() for deletion and querying.
Mongo How to Handle the Operator - Arithmetic Operator,Condition Operator,Logical Operator
MongoDB uses arithmetic operators like $inc, $mul for calculations in updates. Conditional operators like $gt, $lt, $eq filter data based on conditions. Logical operators like $and, $or, $not combine multiple query conditions.
Field update operator
Field update operators in MongoDB modify document fields during updates. Common ones include $set to assign a value, $unset to remove a field, and $inc to increment. Example: db.users.updateOne({name: "John"}, {$set: {age: 30}}).
Array Expression operator
Array expression operators in MongoDB are used to manipulate arrays within documents. Common operators include $push (add to array), $pull (remove from array), and $addToSet (add unique values). Example: db.users.updateOne({name: "John"}, {$push: {tags: "new"}}).
About Indexing in MongoDb
Indexing in MongoDB improves query performance by allowing fast data retrieval. The default index is on the _id field, and additional indexes can be created using db.collection.createIndex(). Common types include single-field, compound, and text indexes.
Aggregation in MongoDb
Aggregation in MongoDB processes data and returns computed results, similar to SQL's GROUP BY. It uses the aggregate() method with stages like $match, $group, $sort, and $project. Aggregation is powerful for complex data transformations and analysis.
About Replication and Sharding
Replication in MongoDB ensures data availability by copying data across multiple servers (primary and secondary). Sharding distributes data across multiple servers to handle large datasets by partitioning the data. Both enhance performance, scalability, and fault tolerance in MongoDB.
Learn what Node.js is and set up your environment
Node.js is a JavaScript runtime built on Chrome's V8 engine, allowing server-side development with JavaScript. To set up, download Node.js from nodejs.org, install it, and verify with node -v in the terminal. Use npm (Node Package Manager) to manage packages and dependencies.
Create web servers with the HTTP module
Here are the theoretical short notes on creating web servers with the HTTP module in Node.js: 1. HTTP Module: The http module in Node.js allows you to create a server that listens for client requests and sends back responses. 2. createServer() Method: This method is used to create an HTTP server. It takes a callback function that handles incoming requests (req) and sends responses (res). 3. Listening on a Port: The server is set to listen on a specific port (e.g., 3000) using the listen() method, enabling it to accept incoming requests. 4. Request and Response: The req object represents the client's request, while the res object is used to send data back to the client.
Work with built-in modules (File System, URL, Events)
Node.js has built-in modules like: 1. File System (fs): Allows reading and writing files (e.g., fs.readFileSync(), fs.writeFileSync()). 2. URL: Provides utilities for URL resolution and parsing (e.g., new URL()). 3. Events: Enables event-driven programming with the EventEmitter class (e.g., emitter.on('event', callback)).
Use Node Package Manager (NPM) to manage packages
NPM (Node Package Manager) is used to manage JavaScript packages in Node.js. Use npm init to create a package.json file and npm install to install dependencies. To install globally, use npm install -g and to update, use npm update.
Handle files (upload, read, create, update, delete)
NPM (Node Package Manager) is used to manage JavaScript packages in Node.js. Use npm init to create a package.json file and npm install to install dependencies. To install globally, use npm install -g and to update, use npm update.
Handle files (upload, read, create, update, delete)
In Node.js, the fs (File System) module handles file operations. 1. Use fs.readFile() to read, fs.writeFile() to create/update, and fs.unlink() to delete files. 2. Use fs.appendFile() to append content, and fs.existsSync() to check file existence.
Send emails using Node.js
To send emails in Node.js, use the Nodemailer package. Install it with npm install nodemailer and create a transporter with email service credentials. Use transporter.sendMail() to send emails, specifying sender, recipient, subject, and message.
Connect and work with MySQL database
To connect to a MySQL database in Node.js, use the mysql package (npm install mysql). Create a connection using mysql.createConnection() with your database credentials (host, user, password, database). Use connection.query() to execute SQL queries and interact with the database.
Create and manage MongoDB databases
To create and manage MongoDB databases, use the MongoDB Node.js driver. Connect to the database with MongoClient.connect() and specify the database name. Use methods like db.collection() to create collections and collection.insert(), find(), update(), and delete() for data management.
Build real-world applications with Node.js
To build real-world applications with Node.js, use frameworks like Express.js for routing and middleware. Integrate databases (e.g., MongoDB, MySQL) for data storage and management. Leverage modules like Nodemailer for email, Passport for authentication, and Socket.io for real-time communication.
About Express, Installation Setup
Express is a minimal and flexible Node.js web application framework for building APIs and web apps. To install, run npm install express and create a server by requiring and using the express() function. Set up routes with app.get(), app.post(), and other HTTP methods to handle requests.
About Request and Response - Get and Post
In Express, req (request) holds data from the client, like parameters, body, or query strings. res (response) is used to send data back to the client, such as status codes and content. Use app.get() for handling GET requests (retrieve data) and app.post() for handling POST requests (send data).
Express About Routing
Routing in Express defines how an application responds to client requests for specific URLs and HTTP methods. Use app.get(), app.post(), etc., to define routes for different HTTP methods and paths. You can also create route parameters (e.g., /user/:id) and handle them using req.params.
About Cookies
Cookies store data on the client’s browser, commonly used for session management and user preferences. In Express, use the cookie-parser middleware to handle cookies. Set cookies with res.cookie() and access them via req.cookies.
File Upload
To handle file uploads in Express, use the multer middleware. Install it with npm install multer and configure it to specify storage and file types. Use upload.single('file') or upload.array('files') to handle single or multiple file uploads in routes.
About Template and Middleware
Template engines (e.g., Pug, EJS) generate dynamic HTML by embedding JavaScript code in views. Use res.render() to render views with data. Middleware functions process requests before reaching route handlers, modifying requests or executing code (e.g., app.use() for parsing JSON).
How to Create the Basic HTML Web Page Using CSS?
HTML5 web forms are created using the <form> element with various input types like <input>, <textarea>, and <select>. Attributes like action (form submission URL) and method (GET/POST) control form behavior. HTML5 introduces input types such as email, password, and date for built-in validation and user experience.
Creating HTML5 Web Forms
HTML structures the web page using tags like <html>, <head>, and <body>. CSS styles HTML elements by controlling layout, colors, fonts, and more. CSS can be embedded, linked externally, or written inline to apply rules to specific elements.
How to Add Bootstrap Themes in HTML Web Page
To add Bootstrap themes, include the Bootstrap CSS file in your project, either locally or through npm. Then, reference Bootstrap classes like container, btn, or navbar within your HTML elements. This will apply pre-defined styles and responsive design features to your webpage.

Introduction about Angular
Angular is a TypeScript-based framework for building dynamic single-page applications. Advantages of Angular include two-way data binding, modularity, and a comprehensive toolset for scalable apps. A Single Page Application (SPA) loads once and dynamically updates without refreshing the whole page. A library offers reusable code, while a framework provides a structure and enforces conventions in app development.
Environment Setup
Environment Setup: Install Node.js and Angular CLI to start developing Angular applications. Installing NODE JS: Download from the official website and install to enable server-side JavaScript execution. NPM & Angular CLI: NPM manages packages, and Angular CLI is a tool for scaffolding and managing Angular projects.

Angular Components
Understanding about Components: Components control specific UI parts using HTML, CSS, and TypeScript. How to create the Component?: Use ng generate component name to auto-create component files. Component Structure: It includes .ts, .html, .css, and .spec.ts files per component. Basic of ngOnInit(), Constructor(): Constructor runs on creation; ngOnInit() handles initialization logic. About Lifecycle: Lifecycle hooks manage a component’s creation, update, and destruction. Working with Angular Decorator: Decorators like @Component define metadata and enhance component behavior.
Understanding about Binding
Binding in Angular connects component data to the view, ensuring synchronization. It includes one-way (data flows from component to view) and two-way (syncs both ways) binding. This mechanism automatically updates the view when the component data changes.
Event Binding and Data Binding
Data Binding:
Links component data to the view, using one-way or two-way binding.
Event Binding:
Binds DOM events to component methods to trigger actions on user interaction.
Working with One way binding and two way binding
Working with Style and Class Binding
- Style Binding: Dynamically binds CSS styles to elements using [style.property] or [ngStyle]. It allows conditional styling based on component data.
- Class Binding: Binds CSS classes to elements using [class.className] or [ngClass]. It conditionally applies or removes classes based on component properties.
Working with event binding
Event binding listens to DOM events, such as clicks or key presses. It triggers component methods when an event occurs. Used for handling user interactions and initiating actions.
Understanding Dependency Injection
Dependency Injection (DI) provides components with the services they need through constructor injection. It promotes loose coupling and enhances testability. Angular’s DI system manages service creation and sharing across components.
Creating Angular Form and Validation
Angular forms can be template-driven or reactive, allowing dynamic control over form elements. Built-in validators like required, minLength, and email help ensure data integrity. Custom validations can also be implemented for more specific form requirements.
About Directory
In Angular, directories help organize the project's files, such as components, services, and modules. A well-structured directory makes the application scalable and maintainable. Common directories include src/app/components, src/app/services, and src/app/modules.
About Custom Directory
Custom directories are user-defined folders to organize specific features or components. They help manage the project structure according to the developer's preferences. Custom directories improve scalability and maintainability of large applications.

Dependency Injection (DI) provides components with the services they need through constructor injection. It promotes loose coupling and enhances testability. Angular’s DI system manages service creation and sharing across components.
Angular Pipes
Pipes transform data in the template, such as formatting dates or filtering lists. Common built-in pipes include date, uppercase, and currency. Custom pipes can be created to apply specific data transformations.
Angular Routing
Angular Routing enables navigation between different views or components based on URL paths. It is configured in the app-routing.module.ts using the RouterModule. is used in the template to display routed components.
Understand about Event Emitter
EventEmitter is used to send events from child components to parent components. It is typically used with the @Output decorator to pass data or trigger actions. This facilitates communication between components in Angular applications.
Introduction to Observable and Observer
Observables represent asynchronous data streams that emit values over time. Observers subscribe to observables and react to emitted values or changes. They are essential in Angular for handling asynchronous tasks like HTTP requests and events.
