Now let us examine the advantages and disadvantages of Node.js when it is used for server-side programming.[/ultimate_heading][/vc_column][/vc_row][vc_row height=”small” gap=”5″][vc_column][ultimate_heading main_heading=”NODE.JS Advantages” alignment=”left” spacer=”line_only” spacer_position=”middle” line_height=”1″ main_heading_style=”font-weight:bold;”]Easy to scale horizontally as well as vertically
Developers need not use any other server-side programming language
Support assured for various commonly used tools
Node.js enables the developers to have the extended support for a number of tools which are used commonly. Those who want to test the source code of Node.js application can make use of the unit-testing tools like Jasmin. The npm, which is a very powerful package manager, can be used for identification as well as installation of project dependencies. For task running of a project, one can make use of grunt.
Simultaneous processing of multiple requests
The non-blocking I/O systems option provided by Node.js enables the users to carry out simultaneous processing of multiple requests. Node.js ensures fast as well as systematic execution of all incoming requests. When compared to other systems such as Ruby and Python, Node.js more efficient in simultaneous handling of multiple requests.
Caching single modules
Node.js has the advantage of caching single modules because of its open-source runtime environment. When there is a request for the first module, the same is cached in the application memory and caching enables the applications to load the web pages faster so as to respond to the user more quickly. As a result, the developers need not re-execute the codes.
Developers can develop apps and software
Another great advantage of Node.js is that it assures the developers freedom to develop apps and software. This advantage is not there with Ruby or Rails since they impose the guidelines. In the case of Node.js for developing apps, one can start from the scratch.
Support of an active community
Can be customized and further extended
Node.js can be easily customized and extended further as required by the developers. When the facility to exchange data between the web server and the client is needed, one can use JSON. Node.js also offers the facility of built-in APIs which can be used for developing different types of servers like HTTP, TCP, DNS and the like.[/ultimate_heading][/vc_column][/vc_row][vc_row height=”small” gap=”5″][vc_column][ultimate_heading main_heading=”Now what are the disadvantages of Node.js?” alignment=”left” spacer=”line_only” spacer_position=”middle” line_height=”1″ main_heading_style=”font-weight:bold;”]API is not stable
The Application Programming Interface of Node.js does not remain stable and changes frequently. Sometimes, new API appears with a lot of changes which are not backwards-compatible. In such a situation, the developers are compelled to bring changes in the accessible code bases in order to match with the latest Node.js API version.
Lack of strong library support system
Asynchronous Programming model is more difficult
For those who want to make the Node.js applications more scalable, it is very essential to adopt the asynchronous programming model. According to most of the developers, when compared to the linear blocking I/O programming, the asynchronous programming model is more difficult. Another disadvantage is that with asynchronous programming, the codes get clumsy and the programmers are forced to depend on nested calls.[/ultimate_heading][/vc_column][/vc_row][vc_row height=”small” gap=”5″][vc_column][ultimate_heading main_heading=”Conclusion” alignment=”left” spacer=”line_only” spacer_position=”middle” line_height=”1″ main_heading_style=”font-weight:bold;”]
