JavaScript is being the most popular and preferred client-side programming language and commonly used JS is the Node.JS Web development tool for front-end. JavaScript is built with remarkable features which makes it more special and dynamic to use rather than the other programming language. Node.js can be considered and appraised for this well-documented popularity.

Let’s have a look on what exactly the Node.Js is?

What is Node.js?

As you know JavaScript is the best choice for the best and versatile web development project. Node.js is one of the frameworks which is used in many applications and server-side programming.

Server-side programming includes the designing of the content of the web page on the server.

Node.js handles browser requests, offers asynchronous, event-driven I/O APIs to get the results quickly and precisely. It is working on a single-threaded event-based loop.

Node.js plays quite fabulous role when joined with latest technology stack. Let’s discuss a detailed overview of Docker in Node.Js:

Applications using NodeJS

Because of these advantages, so manyNode.JS Web Development companies highly prefer Node.js for their web and application developments.

Node.JS is majorly found in every application we use in our day-to-day life. Applications such as Netflix, Ola, Uber, BookMyShow and many others. These applications are engaged with a huge amount of traffic each day from all over the globe. These applications are completely developed in the Node.js framework. Node.JS assists in the smooth and flawless operations of the applications.

What is Docker in Nodejs?

Docker is a new technology that allows developers to build, manage, and secure applications anywhere. Docker is a command-line interface (CLI) and Engine. In March 2013 Docker was created by dotCloud and renamed itself to Docker Inc. Because of its possibilities to open for software delivery and deployment Docker is very popular. Docker is popularly known because it is very easy to use and it can be learned quickly. Docker is an open-source containerization platform with operating systems that support Virtualbox. Docker is for Windows/Mac and it also supports containers natively such as Linux. In fact, it is one of the preferred kind of platforms used for development in many top-class Nodejs web development companies.

Docker ensures that the functioning of the application is irrespective of changes in the environment. Docker is a tool using the container to make the creation, deployment, and execution of applications. Containers like Ubuntu, CentOS, etc. these are basically based on your requirement with respect to operating systems.

The most important aspects of Docker are Dockerfile, Docker Images, and Docker Containers. If we talk about Dockerfile then it is a text document that contains the list of commands. Command list which can be invoked by a user and the user using the command line to assemble an image. Docker automatically builds images by reading instructions from the Dockerfile. Docker image, you can consider as similar to a template that typically used to build Docker containers. Templates are nothing but you can say it is a building block of a Docker Container. Docker Container, it is a running instance of a Docker Image. Docker containers hold the complete package that is required to execute the application.

How do you use Docker in Nodejs

The use of Docker in Nodejs is given as follows:

  1. Docker has the capability of speeding up the application deployment process
  2. Docker is easy in use and very simple to maintain
  3. By using Docker anyone can easily share Dockerfiles and Docker Images
  4. Docker puts minimal overhead on the applications just because Docker has a very lightweight footprint
  5. Docker makes the version control very easy and promotes component reuse
  6. Docker makes the application portability and machines easier

If you are planning to use Docker with Node.js then you need to make sure that Docker is already installed in your system. If you want to Dockerize a Node.js application, first you need to go through the creation of Node.js application, create a Docker file, build Docker image and then execute. After running the installation, Docker-compose will bring up a development environment that works exactly similar to it like on your local machine. If you want to make a Dockerfile then you don’t always need to use Docker.

Docker operating containerized applications is more flexible and resilient; it also handles the running and monitoring of hundreds or thousands of containers. Software-defined networking supported by Docker. Development Teams can design systems with complex network technologies and network in configuration files. If you want to design your software for high loads and performance, then Docker can help you to make it happened.

Advantages of Node.js Development in Web applications

-Following are the Pros of using Node.js as server-side programming:

  1. Easy to learn: Many developers are good with JavaScript as it is one of the most popular programming languages. Developers who are well familiar with the JavaScript find it easy to use Node.js as a backend. Easy to learn and consumes lesser time.
  2. Offers easy scalability One of the key benefits is that Node.js makes it easy to scale the application in horizontal as well as vertical ways. In Horizontal scaling, adding an extra node to the current system it is performed while in vertical scaling, allows adding extra resources to the single node.
  3. Full-stack JavaScript: It is entitled as Full-stack JavaScript for server-side programming as well as client-side programming. Hiring a Full-stack developer contains both Front-end and Back-end developer which saves your money and time.
  4. Single Programming Language: Node.js allows developers to write server-side applications in JavaScript which means a developer can write front-end and back-end applications in JavaScript in the run-time environment.
  5. Offer High Performance: Node.js rewrites the code through the Google V8 JavaScript engine. It compiles the code in the engine. So, it’s easy to implement the code and it is done speedily and most effectively.

Disadvantages of Node.js Development in Web applications

-Following are the Cons of using Node.js as server-side programming:

  1. API is not stable: One of the major problems that developers face is that while working on Node.js is the Application Programming Interface (API) keeps changing at certain intervals and doesn’t remain stable. It is observed that the new API with several backward-incompatible changes which results in performing changes in the accessible code bases to remain in tune with the latest version of Node.js.
  2. The library support system is not strong: As compared to other languages, JavaScript does have a robust and well-equipped library system. As a result, developers are accessing the support from the common library for several tasks such as handling database actions, Object-relational mapping, XML or parsing, etc.
  3. Asynchronous programming model: To boost scalability, the application should follow an asynchronous programming model. Moreover, Developer finds it more as compared to linear blocking I/O programs.

Conclusion

Node.js offers numerous advantages as compared to its disadvantages. However, it allows JavaScript application developers to be appointed as both Front-end and Back-end developers by titling them as Full-stack developers. With the progress of time, more and more businesses are adopting Node.js and ended in getting positive results for their business.
