This eliminates the need for developers to switch between different syntaxes and simplifies the integration process. Moreover, NodeJs’s ability to handle JSON data natively ensures smooth and efficient data processing, unlike other frameworks that require additional conversion steps.
6. Single Codebase for Real-Time Applications
With NodeJs, developers can write JavaScript code that runs on both the server and client sides. This unique feature enables automatic synchronization of data between the server and client, making it easier to build real-time applications.
Frameworks like Meteor take full advantage of this capability by executing the same codebase on both ends. As a result, any changes made on the server immediately reflect in the client, leading to a seamless user experience.
7. Proxy Server Solution
NodeJs can serve as a powerful proxy server, especially when an enterprise needs to communicate with various third-party resources, store videos or images, or collect data from multiple sources.
By utilizing NodeJs as a proxy, enterprises can efficiently manage diverse services with different response times or consolidate data from various sources.
This makes it an ideal solution for enterprises without an existing infrastructure for proxies or those seeking local development options.
8. Increased Productivity
NodeJs promotes increased productivity by allowing developers to use JavaScript for both frontend and backend development. This integration eliminates the traditional silos between frontend and backend teams, streamlining the development process.
Enterprises can merge their teams into a single unit, reducing inter-silo dependencies and enhancing efficiency. PayPal, for example, witnessed a significant increase in developer productivity and faster application delivery after adopting NodeJs.
9. NodeJs Hosting Services
