Express.js, Node.js, MongoDB, and AngularJS Web Development | What Is the DIfference

The demand for MEAN stack developers, especially the Node.js has increased constantly from its beginning in 2009. Many big, medium and small organization have regular requirements to hire Node developers for their software development projects. Node JS has been used in multiple combinations of technologies to improve performance, speed, and quality of web products and save the development cost and time.

Express.js, Node.js, MongoDB, and AngularJS Web Development – MEAN

Both the client-side and server-side JavaScript frameworks have revolutionized the web development with MongoDB and NodeJS in combinations with other technologies completely. The newer combinations of Node JS and Angular JS with other back-end technologies have emerged in the marketplace. MongoDB, Express JS, Angular JS, and Node JS precisely referred to as ‘MEAN’, is one of such popular combinations for node based programming. The Node Express Angular is another very popular technology combination extensively used in the field of professional web development.

The four technologies in the MEAN stack are MongoDB, Express.js, AngularJS, and Node.js, which fittingly form the acronym MEAN. These all four components of MEAN stack are either JavaScript-based technologies or are fully compatible with the JavaScript language.

The image below shows the request-response cycle in a MEAN stack application, which depicts the arrangement of each of the four technologies in the application, as well as the flow of data through the application from the moment a user sends a request to the application, until the moment the user gets a response.

Let’s talk about the features, capabilities, advantages of those technologies individually:

Node.JS Technology

Released in 2009 by developer Ryan Dahl, Node.js is truly a breakthrough in the world of software engineering. Node.js is a run-time environment that enables JavaScript codes to be executed on the server side, thus allowing the program access to the server’s hardware components like its memory and processor. This is not possible with client-side code execution, to which JavaScript was primarily confined prior to the release of Node JS for web development.

Since JavaScript is the client-side scripting language of all web applications, the ability to run JavaScript on the server side offered invaluable advantages and conveniences to web development. It essentially abolished the wall that divided frontend and backend development, making full stack development a unified experience. The compatibility of the Node MongoDB combination in web application development is very well known for its high-performance and easy implementation. The web development with Nodejs and MongoDB is highly preferred for the commercial web environments where the performance, speed, and reliability of the service are among the top priorities.

Angular JS Technology

Angular JS is a front-end web application platform for building dynamic applications. It is based on the JavaScript technology built by Google Corporation. It is an open-source platform available to use under MIT license. The first version of Angular JS was released in 2010. The Angular front-end web development with MongoDB and Node.js technologies is in high demand nowadays.

Angular JS is 100% suitable for building single page applications SPAs in cross-platform web development environment. This technology allows you to extend HTML syntax for expressing the web components of your dynamic web applications more clearly. The Node.js MongoDB and AngularJS web development is extremely popular in the field of full-stack application development environment.

Advantages

  • Easy to learn and use through HTML declarative programming
  • Free to use under MIT license
  • Powered by Google
  • Effective code reusability
  • Numerous plug n play components
  • Fast code development
  • Reduced development cost

Disadvantages

  • Too many options confuse the developers to choose the right option
  • UI lags due to Angular form limitations

  • Fast, flexible, efficient
  • Great for web applications as well as mobile applications
  • A strong part of MEAN stack development
  • Larger community and support

Disadvantages

  • Some manual tasks involved that make it a bit tedious
  • No built-in error handling mechanism

MongoDB Database

MongoDB is a nonrelational or NoSQL database program. It is a cross-platform and document-oriented program available as an open-source program to use. The initial release was launched in 2009. It is released under Apache and Server Side Public License (SSPL) licenses.

It is a highly flexible and scalable database document that works on JSON-like document database schemas. It is highly compatible with the Express.JS platform for the backend integration of database in the MEAN stack environment. This program is written in JavaScript, C++, and C languages.

Finding Node JS Developer For Hire

Node.js has revolutionized the web development both on the server-side as well as on the client-side. Node.js is server-side JavaScript programming that runs on the server as well as in the browser. In connection with the JSON data format, the web development has attained the new heights. This is the reason, that enterprises seek for Node JS developers to hire for their dynamic web application development. There is a huge demand in the marketplace to realize the power of JavaScript language in the web development.

Freelancers

There are several freelance portals from which you can hire freelance MEAN stack Node JS developers, such as Upwork, Freelancer, and Toptal. Due to the intense competition among freelancers on these portals, this method can be very cheap. However, it comes with some serious risks. You will have little control over your freelancer, and he can opt out of the project at any time for a variety of reasons, so this method tends to be unreliable. Moreover, time zone differences and language barriers may make communication and collaboration more challenging.

Local In-House Developers

You can also directly hire Node JS MEAN stack developers from your local market through job posting websites, and they will become your company’s in-house developers. This method gives you full control over your project and developers and will eliminate problems related to the time zone and language differences. However, it can be quite expensive to hire Node developer, as their rates can be high in many countries. Moreover, you will need to allocate physical resources such as office workstations and computers, as well as pay additional fees like taxes and insurance, further increasing the costs. Also, this often involves long-term contracts, so you can’t simply let your employees go once your project is done.

Outsourcing Companies

Another option would be to hire an outsourcing company who will be responsible for the completion of your entire project. This involves explaining the entire project to their business analysts and project managers, who will be the one to assign tasks to their developers. This method takes a big chunk of the workload from you, but can also get quite costly due to additional services like project management and business analysis. Moreover, it leaves you with limited control over your project and is therefore prone to misunderstandings which can cause delays and further increase costs. Also, as with freelancers, time zone and language differences may be a problem.

ways to hire node express angular developer

Clearly, offshoring proves to be the most economical and practical method for hiring a Node.js MEAN developer. One drawback of this method is, as with freelancing, outsourcing and outstaffing are that time zone and language differences may lead to difficulties, so choosing the right country and company to offshore from is very important. And how to choose the best country with affordable Node JS developer salary and high quality we are discussing further in our blog.
