Node JS Training in Hyderabad

An introduction to Node JS :

Node.js is an open-source as well as a cross-platform JavaScript runtime environment. It is a widespread tool for almost any kind of project. Node.js drives the V8 JavaScript engine, the core of Google Chrome, outside of the browser. This enables Node.js to be very performant. A Node.js app operates in a single process, without creating a new thread for every request. Node.js presents a set of asynchronous I/O primitives in its standard library that prevent JavaScript code from blocking and generally, libraries in Node.js are written using non-blocking models, making blocking behavior the exception and not the norm.

When Node.js delivers an I/O operation, like reading from the network, accessing a database or the filesystem, instead of blocking the thread and wasting CPU cycles waiting, Node.js will continue the operations when the response comes back. This allows Node.js to manipulate thousands of concurrent connections with a single server without introducing the difficulty of managing thread concurrency, which could be a significant source of bugs.

Node.js has an uncommon advantage because millions of frontend developers that write JavaScript for the browser are now capable of writing the server-side code in addition to the client-side code without the necessity to learn a completely different language. In Node.js the latest ECMAScript standards can be used without problems, as you don't have to wait for all your users to update their browsers - you are in charge of deciding which ECMAScript version to use by adjusting the Node.js version, and you can also enable specific experimental features by running Node.js with flags.

Node.js Frameworks and Tools :

Node.js is a low-level platform to work with. To make things easy and exciting for developers, there are thousands of libraries built upon Node.js by the community of developers.

• AdonisJS: A TypeScript-based fully-featured framework highly focused on developer ergonomics, stability, and confidence. Adonis is known to be one of the fastest Node.js web frameworks.
• Egg.js: A framework to build better business frameworks and apps with Node.js & Koa.
• Express: It provides one of the most simple yet compelling ways to create a web server. Its minimalist strategy, unopinionated, focused on the core features of a server, is key to its success.

• Loopback.io: Makes it easy to develop modern applications that require complex integrations.
• Meteor: An astonishingly powerful full-stack framework, powering you with an isomorphic approach to building apps with JavaScript, sharing code on the client and the server. Once an off-the-shelf instrument that provided everything, now integrates with frontend libs React, Vue, and Angular. Can be used to create mobile apps as well.
• Micro: It provides a very lightweight server to build asynchronous HTTP microservices.
• NestJS: A TypeScript based growing Node.js framework for building enterprise-grade efficient, reliable, and scalable server-side applications.
• Next.js: React framework that supplies you the best developer experience with all the features you need for production: hybrid static & server rendering, TypeScript support, smart bundling, route prefetching, and more.
• Nx: A toolkit for full-stack development using NestJS, Express, React, Angular, and more! Nx helps scale your development from one team-building one application to many teams collaborating on multiple applications.
• Sapper: Sapper is a framework for building web applications of all sizes, with a wonderful development experience and flexible filesystem-based routing. Offers SSR and more!
• Socket.io: A real-time communication engine to develop network applications.
• Strapi: Strapi is a flexible, open-source Headless CMS that provides developers the freedom to choose their favorite tools and frameworks while also allowing editors to easily manage and distribute their content. By making the admin panel and API extensible through a plugin system, Strapi empowers the world's largest companies to accelerate content delivery while building beautiful digital experiences.

JavaScript Developer ( Node JS ) :

JavaScript developers can target more platforms than any other high-level language, as JavaScript is the most popular programming language with the most valuable OSS module ecosystem available. It is used to create interactive web pages, user experience, and responsive front-end design. Anything a user clicks, inputs, edits, or pulls up on a website is conceivable. JavaScript developers are accountable for a website's programming, development, and implementation, and may find themselves balancing a variety of programming duties that go into the creation of websites. They may be in charge of a whole site or just specific aspects or pages of one or more websites. Web development is a very challenging job that needs a variety of skills, including collaboration, communication, and technical writing. Drive and self-motivation Being a quick and enthusiastic learner Communication & collaboration. Being detail-oriented and big-picture oriented. Familiarity of math, logic, & abstraction. Retaining skills sharp with continual learning.

What is the workplace of a Javascript Developer like?

JavaScript has up until lately been primarily used on the front end. As Express and NodeJS (tools for building JavaScript backends) gain in popularity, demand for JavaScript developers will grow. Javascript developers are found working in numerous types of organizations, including large corporations and governments, small and medium-sized companies, or alone as freelancers. Some work for one group as a permanent full-time employee, while others may work as independent consultants, or as contractors for an employment agency. There is a national standing need for thousands of remote JavaScript developers across the US, and there are similar remote openings around the globe, which provides amazing opportunities.
