Web development is a popular sector and web developers are in huge demand by the technological industry. Developers use various frameworks and software to successfully do their job. Nodejs is one such framework.
A single-threaded environment, parallel running of different sections of an application on Node.js is forbidden. CPU binding code like long loops and large arrays slow down the application which must be avoided at all costs for the smooth functioning of the application. Certain methods solve this problem with smaller arrays or loops but will deteriorate performance for bigger ones with multiple connected clients. The best solution to that problem is to face each issue individually so that the CPU is not overwhelmed by the concurrent functions.
Not using the consoles-
Testing an application is extremely necessary before it is delivered to the client. If the application contains bugs, it might cost the clients thousands of dollars. Many developers tend to ignore such an important part and often deliver apps with just manual testing. These types of testing are prone to error and writing tests that are automatic and cover all the areas covered by your application is very important and cannot be avoided if one wants to do their job properly.
Having a supervisor program monitor your application can be quite beneficial, even if the application seems to be running smoothly in local environments. These programs ensure that developing on Node is pleasant since they help restart programs if they cash or if certain files change. Various programs like forever, nodemon, pm2, etc. are available for Node and should be chosen based on the necessities and comfort of the developer.
Even though Node is a very adaptable framework, if these mistakes are made, working on it can be frustrating. They can cause significant damage to and must be avoided.
