For Learning Node.Js, What Are The Best Resources That Can Be Used?

In general, you should write small programs that do one thing well. Stream data between processes, and read those streams using evented interfaces. That is the Node way. Understanding Node’s asynchronous nature is fundamental. Node just like other languages is great for certain things and not so great certain `things. There are various Node.js resources for learning and Node.js development.

Resources for learning Node.js

  1. An improved 2nd edition book over 1st edition circulated under title “Node Web Development” is the newest. It is printed assuming you are comfortable with programming, with unix and shell level work. It is also considered to make the users comfortable with some basics of web development that can be readily used for js development. It also takes you through installing Node, understanding a series of applications from trivial to somewhat useful, shows how to build simple REST service, handle user authentication, some unit testing techniques and even a real-time chat application.
  2. Once you are familiar with the Node Landscape, nodeschool.io is just a great resource. There two good books available for reading- “Hands-on Node.js” & “The Node Beginner Book”, that you can find most useful for learning Node.js.
  3. One great resource is TJ Holowaychuk’sMastering Node, which is “open source eBook for Node.Js”- written with markdown outputs to various formats (pdf, epub, mobi, HTML, etc.)
  4. One of the best resources is nodeschool.io. You can install these, choose your own adventure style lessons and learn how to use Node.js, NPM and other associated tools by writing code to answer realistic problems. The instructions run in your terminal and work on Windows, Linux and Mac.
  5. If your goal is to understand how Node.js is useful in the context of creating a web application, you can check out Talentbuddy’s Full Stack Web Development mentorship program. The learning experience is engrossed on teaching the distinctive challenges of building real-time web applications with fast-growing technologies (including Node.js, Express.js, Ember.js, JavaScript and MongoDB).
  6. js has gained a lot of popularity among web developers although being a relatively new technology. It is essentially a server-side JavaScript environment that uses an asynchronous event driven model. It means it is an environment for writing scalable, high performance network applications.
  7. You can use handy tools to detailed tutorials, in-depth articles and resources on this promising technology to know the most useful resources for Node.js. Here are few of the useful Node.js Tools:
  • Node Express Boilerplate: It gives the developer a clean slate, while rushing enough useful features to eliminate all of those redundant tasks.
  • IO: It is a cross-browser Web socket that targets to make real-time apps promising in every browser and mobile devices, blurring the distinction between the various transport mechanisms.
  • Mastering Node: Using this, you can write high-concurrency web servers, high-level mobile web development and more.
  • Formaline: It is a low-level, full-featured module for handling form requests and for parsing uploaded files quickly.
  1. Stylus is an expressive CSS markup language for Node.js. The compiler is written in Node.js. Jade is a template engine for Node.js applications that combines great power and flexibility with a nice and clean syntax.

Despite being a little young, Node.js already has a huge number of libraries for every possible application. Node.js is constantly changing and growing with each new version. Node.js has gained a lot of popularity among web developers although being a relatively new technology.

Node.js is among the best application service provider but is it overrated?

Node.js is useful and of course it is always “right tool for the job”. It is a highly accessible language and directly relevant. Also it isn’t a very good language, but it is vaguely familiar. Programming has never been as easy to get into as it is now, and accessibility of JavaScript and utility of Node.js has definitely helped on that front. Node.js is hot right now because something has to be in fashion. The programming scene is every bit as fashion driven as anything else.

Is it overrated?

  1. The three most important things about Node.js that works together so well for many people are:
  • Non-blocking I/O. This is what it owes and also provides a high performance. Multi-threaded solutions exclusively opening a single thread for every solo concurrent user, and can really present some scalability issues as consumer usage grows.
  • It’s JavaScript on the backend. This may not seem like a big deal, but it basically means reduced complexity because that’s one less bit of expertise in your stack that developers have to reason about.
  • NPM, which is the largest module ecosystem in existence, and still growing. It is not only the package manager in existence, but it’s certainly got the largest and most energetic ecosystem, which upturns the likelihood that you will find whatever it is that you need for your project.
  1. If people celebrate Node.js for the above reasons, then they certainly are not “overrating” it. It deserves such praise. However, if somebody goes to oversell it by making it out to be flawless in every other way, then sure, that’s overrating it. But that is largely a matter of certain individuals, and not the technology in question. In and of itself, it’s one serious piece of work.
  2. js just turns for a large number of projects, and it positively stimulates the paradigm of asynchronous, event-based programming better than most other languages. It may be that some of the more simplistic prerogatives about Node.js presentation could be measured overrated, such as when Apache or Nginx with several modules enabled are equated in connections per second to a barebones Node.js server.
  3. Talking about Node.js single-threaded libev based programming model for a moment- it was shaped to solve definite problems in the web server problem space- namely, spinning up a separate thread for each client that needs to talk to the server is problematic as scale grows large.
  4. Determining if Node.js is overrated depends on two things:
  • Your expectations of Node.js
  • The capabilities of Node.js

So, does Node.js Application Development do more or less than what you think it can do? As long as you have proper expectations then it is neither overrated nor underrated. You can use Node.js Application Development service for what it’s good at and you will have a good experience. This holds true for any technology, but use the right tool for the right job.

Node.js is always fashionable in the market. It allows people to write not only server-side stuff, but to automate things. Yes there are some concerns when it comes to certain packages, but for most of the time, for 95% of what people need, it’s fast and gets the job done with just a few key strokes. It is like apt-get for web libraries.

Best online Node.js courses for Node.js application development

There are various courses that help you build a full app with a REST API using just Node.js and MongoDB, Express.js, Angular as well as Iconic for mobile, that courses are really very good for Node.js application development.

Best online course for Node.js application development

  1. There are some courses in Plural sight which you may find very useful for your work. Some other courses are in Microsoft Virtual Academy who provide you with projects code which are available on GitHub but they won’t walk you step by step because it is a jump start and they don’t have all the time to walk you through, but they give the real deal.
  2. If you are looking for a project based course that will in-build real-world Node.js web applications, you can try Workshops – Talentbuddy. You will find a RESTful API for an app similar to Twitter and learn with the help of videos, curated tutorials and mentors.
  3. There are two resources to cover the two different sides to learning Node:
  • Learn All the Nodes
  • Learn Your Node

These two covers the two sides of learning to code:

  1. Intuitive lectures
  2. Coding through challenges

It is better to use both techniques; Learning all the Nodes and Learn your node together but focus on the building that you do with learning your node.

  1. Courses for js application development can be categorized in different ways. They are:
  2. js for Beginners course, which makes you understand the foundation of the Node.js command line
  3. From Zero to Hero Node Program, this makes you learn enough Node.js, MongoDB and Express.js to deploy apps to cloud. It also helps you learn use Git for for deployment to Heroku.
  4. Learn Node.js by Example course, which help you explore what Node.js is, and when to use it.
  5. Introduction to Node.js Development course, which makes you learn to create a server using Node.
  6. JavaScript Server Technologies from Scratch Course, which preaches you to create robust and scalable web applications.
  7. Advanced Node.js Development course, which assist you the methods to improve functionality of web applications.
  8. js is a powerful tool for controlling web servers, building applications, and creating event-driven programming. You can learn all about Node.js and start creating JavaScript applications in this course. The course begins with Node’s circumstantial, perceptions and policies for writing asynchronous code. So after the course and training, you will be able to critic if the specific features of Node can benefit you in your projects. You will learn Node.js codes for Node.js application development from Beginner level to advanced level in this single progression.
  9. The coach may start preaching from the beginner level. He then examines Node’s module system, which also includes built-in modules, application modularization as well as the NPM third party module office. Next pace would be, using Node to write both client and server web applications, as well as real time integration with Socket.IO.

Developers can acquire a lot with the aid of videos, curated lectures and guides during the course period. These courses will help your projects to complete in the command line with inspires that are just open enough to have you exploring what to do but strong enough that you don’t give up. Follow the steps aforesaid and you will find a great Node.js developer in yourself.

Apart from innumerable benefits of Node.js development service, what are its shortcomings?

Node is actually a neat platform, and it has an attractive ecosystem. It has got one of the only package managers that actually work. It also drives on the acceptance of the JavaScript language, which provides it somewhat of a buildup status. However, there are limited points where it falls petite, even within the function that it was intended for.

Shortcomings of Node.js

  1. Bad concurrency primitives

The programming language is entirely built on top of the ground of asynchronous I/O. Being a single-threaded platform intensive on I/O bound applications on highest of a language that does not pledge transparency and has no support for co-routines, this is an explicable select. It is much superior than heavy weighted threads with shared states, but it is a poor model of concurrency to expose to the platform.

  1. It is Single – Threaded

Being single threaded, it means that one does not need to care about the problems of synchronizing between threads, or shared mutable state. However, it also means that unlike preemptive concurrency, the programmers themselves have to resolve how to pact with concurrency, with the avoidance being no concurrency at all.

  1. js lack maturity

Most of the core libraries are trustable, and you can trust them to usually do the right thing for Node.js development. But the ecosystem itself is still fairly mature. It is also difficult to access the quality of a precise module because of the deficiency of features for guaranteeing the eminence of code from JavaScript itself. The waynpm is so structured that it makes quite difficult to find trustable packages, and the ease of publishing your own package, together with the Unix-philosophy that goes through part of the community, make it tougher to spot packages that are reliable and verified.

  1. It is reliance on stringly-typed programming

There is a flourishing of “strings are easy” in the open, which hints to many bugs due to futile dependence on strings, rather than fitting data structures.

  1. It is hard for Node.js to make things fault-tolerant

They don’t give all of the tools that are necessary to make systems reliable and fault-tolerant, as OTP/Erlang does. There are no mechanisms to handle or recover from errors that are thrown asynchronously.

  1. js deficiency of intrinsic code organization is a giant disadvantage. It gets especially worsened when the development team as a whole isn’t accustomed with asynchronous programming or standard design outlines. There are just too many ways for code to get disruptive and unsustainable.
  2. js development service is wonderful, and has excellent chance of becoming the gold standard. But as concerned with the disadvantage, the Node API has a habit of changing in backwards-incompatible methods from release to release, and recurrent alterations to your codebase are obligatory to keep things running on the up-to-date version.
  3. Node’s biggest problem at the moment is the amount of duplication of effort taking place when it comes to the network of packages & the expanse of effort paid the best package to use for any agreed task that stems from this.

It really depends on what you’re trying to do with your web app. If you are doing a lot of I/O bound tasks then Node.js is just fine. However, if you find yourself doing a lot of CPU bound tasks than you are enhanced off using Java or whatever JVM language you desire because doing CPU bound tasks in Node.js will wedge the event loop.

Why to choose Node.js for web applications?

The non-blocking I/O operations are a very strong feature of Node.js if a “real time” experience is required since it allows it to handle a large number of long lived connections to the server. Certainly frameworks like Async.js and CoffeeScript can make your Node.js code much more concise if verbosity is a concern. You can find Node.js as a simpler framework to produce a web interface that can deliver an experience that is much more interactive with the user. Node.js developers are regular in web servers and app development which makes it more trusted to choose Node.js for web applications.

Why to choose Nodejs for web applicationsChoosing Node.js

1. Node.js executes all I/O operations asynchronously. This means that it would not make your program wait for the completion of an I/O operation, like accessing a file, a database, a network connection etc.

2. A single thread can manage the execution of multiple panel I/O task, thus making a more efficient use of a cPU and memory resources. This makes it ideal for handling the requests of many simultaneous users on a single machine.

3. Here are the list of features which makes Node.js as goto technology:

• It wins the speed
• It has efficient tooling with NPM
• It also wins the data streaming
• Real time web applications area walk in the park with Node.js

4. It is also suitable to be a game server, it can provide data read and transfer with thousands of users simultaneously. But in enterprise application development, choosing Node.js is not a wise action because Java is more mature in this domain.

5. Node.js is a platform built on Chrome’s JavaScript runtime for easily building fast, scalable network applications. It is perfect for data-intensive real time applications that run across distributed devices. It has the power of dynamic server compatibility, cross platform compatibility and has I/O data driven technology.

6. If you ever want to have an application with real life experiences, it’s time to encourage yourself with that superb feeling because making use of Node.js you can actually transform your ideas into real-life experiences (means an application).

The Node.js single thread event-loop environment was not this only one of its kind but it made this paradigm accessible on the server to a huge community of developers with a very easy way to share contributions. Node handles I/O with an excellent manner and also it is suitable for applications that requires a lot of connections such as online games, chats etc.
