"Node.js is a back-end JavaScript runtime environment, runs on the V8 JavaScript engine, and executes JavaScript code outside a web browser."
A JavaScript runtime for building server-side applications.
Javascript: Node.js is built on top of Javascript, so having a strong foundation in Javascript is essential in understanding Node.js. This includes basic syntax, data types, functions, and object-oriented programming.
Asynchronous programming: Node.js is asynchronous by nature, which means that its event loop allows it to handle many incoming requests efficiently. Understanding how to work with callbacks, promises, and async/await is necessary for writing performant code in Node.js.
Node.js runtime environment: Understanding how Node.js works as a server-side runtime environment is crucial, including how it handles HTTP requests and responses, file system access, and interacting with databases.
NPM: NPM (Node Package Manager) is the package manager for Node.js, and it allows you to easily manage and install third-party packages and libraries that extend the functionality of your Node.js application.
Express.js framework: Express.js is a popular and lightweight web application framework for Node.js that provides a set of features and tools for building and deploying robust and scalable web applications.
REST APIs: Understanding how to design and build RESTful APIs using Node.js is necessary for building web applications that can interact with data from other systems and services.
Websockets: Websockets are a communication protocol for real-time web applications that require bidirectional and low-latency communication between the client and server. Understanding how to use websockets in Node.js allows you to build dynamic web applications with real-time capabilities.
Testing and debugging: Testing and debugging are critical parts of the software development process. Knowing how to write and execute tests, debug errors, and use logging tools for Node.js can help you develop high-quality and reliable web applications.
Security: Understanding the common security threats and vulnerabilities that web applications face, and how to mitigate them, is essential for developing secure Node.js applications.
Deployment and hosting: Knowing how to deploy and host Node.js applications is necessary for making your application accessible to the world wide web. Understanding how to use platforms like Heroku and AWS to deploy and manage Node.js applications is essential for deploying production-ready applications.
Express.js: A web framework for building web applications and APIs using Node.js.
Koa.js: A web framework for building smaller, lightweight web applications and APIs.
Hapi.js: A web framework for building scalable and modular web applications and APIs.
Meteor.js: A full-stack framework that includes both front-end and back-end components, allowing for real-time web applications.
Sails.js: A web framework for building custom, enterprise-level Node.js applications.
LoopBack.js: A framework specifically designed for building RESTful APIs.
NestJS: A framework that leverages TypeScript and builds on top of Express.js, providing a more opinionated and structured way to build Node.js applications.
Fastify: A fast and low-overhead web framework for building web applications and APIs.
Adonis.js: A full-stack web framework that provides a modular way to build Node.js applications.
Socket.io: A real-time engine that enables bi-directional communication between client and server, allowing for real-time web applications.
"Node.js is a cross-platform, open-source server environment that can run on Windows, Linux, Unix, macOS, and more."
"Node.js lets developers use JavaScript to write command line tools and for server-side scripting."
"The ability to run JavaScript code on the server is often used to generate dynamic web page content before the page is sent to the user's web browser."
"Node.js represents a 'JavaScript everywhere' paradigm, unifying web-application development around a single programming language."
"Node.js has an event-driven architecture capable of asynchronous I/O."
"These design choices aim to optimize throughput and scalability in web applications with many input/output operations, as well as for real-time Web applications (e.g., real-time communication programs and browser games)."
"The Node.js distributed development project was previously governed by the Node.js Foundation, and has now merged with the JS Foundation to form the OpenJS Foundation."
"OpenJS Foundation is facilitated by the Linux Foundation's Collaborative Projects program." Please note that the paragraph provided does not include all the necessary information to create twenty distinct study questions.
