The document provides an introduction to building a simple web server in Node.js. It discusses organizing the code into modules, including a server module to start the web server, a routes module to route requests, and a request handlers module. It also covers basic concepts like using the http module to create a server, handling requests, and returning responses. The server currently returns the same "Hello World" response for all requests, and next steps involve routing requests to proper handlers to return the appropriate content based on the URL.

Spring Boot is a framework for creating stand-alone, production-grade Spring-based applications that can be started using java -jar without requiring any traditional application servers. It is designed to get developers up and running as quickly as possible with minimal configuration. Some key features of Spring Boot include automatic configuration, starter dependencies to simplify dependency management, embedded HTTP servers, security, metrics, health checks and externalized configuration. The document then provides examples of building a basic RESTful web service with Spring Boot using common HTTP methods like GET, POST, PUT, DELETE and handling requests and responses.

This document discusses Aspect Oriented Programming (AOP) using the Spring Framework. It defines AOP as a programming paradigm that extends OOP by enabling modularization of crosscutting concerns. It then discusses how AOP addresses common crosscutting concerns like logging, validation, caching, and transactions through aspects, pointcuts, and advice. It also compares Spring AOP and AspectJ, and shows how to implement AOP in Spring using annotations or XML.

React is a library for building user interfaces using components. It uses a virtual DOM for rendering components, which are pieces of UI defined as classes or functions. Components receive data via props and local state, and can be nested to build complex UIs. The component lifecycle includes mounting, updating, and unmounting phases. Data flows unidirectionally down the component tree. React has a vibrant ecosystem and community for continued learning.

This document provides an introduction to Node.js. It discusses why JavaScript can be strange, but explains that JavaScript is relevant as the language of the web.

This document provides an overview of developing a web application using Spring Boot that connects to a MySQL database. It discusses setting up the development environment, the benefits of Spring Boot, basic project structure, integrating Spring MVC and JPA/Hibernate for database access. Code examples and links are provided to help get started with a Spring Boot application that reads from a MySQL database and displays the employee data on a web page.

Express.js is a web application framework for Node.js that provides a flexible set of features for building web and mobile apps. Express apps use middleware functions that have access to the request and response objects and allow for intermediate processing in the request-response cycle. Middleware functions can execute code, modify requests/responses, and call the next middleware function. Express supports application-level middleware, router-level middleware, error handling middleware, built-in middleware like static file serving, and third-party middleware.

The document discusses JavaScript and Node.js. It includes quotes about JavaScript's growing use and influence. It also discusses Node.js features like non-blocking I/O and core modules. Key aspects of the Node.js module system and asynchronous code are explained through examples. Common Node.js APIs, utilities, and the ecosystem are briefly outlined.

Use Higher oder components to separate complicated validation logics from the UI components and make them to be more pure, simpler and easier to test.

This document provides an overview of the MEAN stack and its components. It discusses Node.js and its asynchronous and non-blocking architecture. It introduces MongoDB for data storage. It also covers Express, a web application framework for Node.js, and Angular 2, a front-end framework. Code examples and demos are provided for Node.js, Express, MongoDB integration, and building an Angular 2 application. The document is intended to educate developers on the MEAN stack technologies.

We'll go through the possible ways to bring technology agnostic microservice architecture to the frontend, review pros/cons of each of them. We also will check the "ultimate solution" that handles microservices with SSR in SPA manner. This talk will be interesting for ones who have multiple teams working on the same frontend application.

Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. Node.js is an open source command line tool built for the server side JavaScript code.

This document discusses how to avoid getting lost in the current JavaScript landscape. It begins by looking at modern web development trends like HTML5, CSS3, ES6, and expectations of fast page loads. It then examines traditional page lifecycles versus single page applications and various JavaScript frameworks. The document advocates for progressive enhancement and outlines strategies like "Hijax" and using the HTML5 History API to improve traditional approaches. It also discusses issues like code duplication, the benefits of isomorphic JavaScript, and tools for frontend development including Grunt, Gulp, asset bundlers, and test runners. It concludes by providing recommendations on technologies to adopt, consider, or stop using to develop with a progressive enhancement approach.

This document provides an overview of Node.js, including what it is, its key features, and how to test a Node.js installation. Node.js is a JavaScript runtime environment that allows building scalable network applications in a single programming language.

The document provides release notes for ASP.NET Core 2.0 and discusses features for building single page applications (SPAs) with .NET Core. Key points include: - New SPA templates for React, Angular, and other frameworks that set up projects with bundling and other build tools. - JavaScriptServices allow running Node.js code from .NET and facilitate building SPAs with .NET backends. - SpaServices provide features like server-side prerendering, routing helpers, and Webpack middleware to improve the SPA development experience. - While SPA templates provide a starting point, separate client and server projects with specialized tooling may provide a better development workflow
