Why nodejs is hell

When it comes to Node.js, some people may think that it is a very powerful and globally popular JavaScript running environment. In fact, Node.js is not only a running environment, but also a powerful development tool. Behind this development tool, there are many problems involved. Therefore, some people call it "hell". So, why is Node.js called "hell"?

1. Steep learning curve

The learning curve of Node.js is indeed steep, which is different from writing applications in other programming languages. Many people face many difficulties and challenges while using Node.js. Node.js offers a lot of features and APIs covering various complex and sometimes very technical aspects. Therefore, in order to develop Node.js applications with high quality and high performance, developers need to have a higher level of programming skills and experience.

2. Unorganized Development

Developing Node.js applications often involves the use of many modules and components. In a complex application, these modules and components are often disorganized. This confusion can result in developers not knowing which components are appropriate for a specific application and how to coordinate them. Therefore, even if developers have strong skills and experience, they need to spend a lot of time dealing with coordination and conflicts between various modules.

3. Version issue

There are a large number of modules and libraries in Node.js, and these modules and libraries are frequently updated. But some updates may cause new problems and conflicts due to mutual dependencies. Once this happens, developers need to spend a long time to solve the problem and find compatible modules and versions. This increases development time and cost, and sometimes results in the quality of some applications not being guaranteed.

4. Handling concurrency

Node.js is a platform based on event-driven and asynchronous I/O, which has excellent performance when dealing with insufficient hardware resources. However, when it comes to handling concurrency, the performance of Node.js is not very good compared to other programming languages. This can cause performance issues when your application handles a large number of concurrent connections simultaneously. This is also one of the common challenges in Node.js development.

5. Immature Ecosystem

Although there are many excellent modules and libraries in the Node.js ecosystem, its maturity is still lacking compared to the ecosystems of other programming languages. Not high enough. This may result in developers spending more time building the module themselves, or making appropriate modifications. This requires a higher level of skill and experience, and can be a challenge for some developers.

To sum up, there are indeed many difficulties and challenges in the development of Node.js, which makes many people think that Node.js is "hell". However, this does not mean that Node.js has no advantages. As mentioned before, Node.js is a powerful and efficient development environment. The key is that developers need the skills and experience to overcome these challenges and ultimately build high-quality, performant, and reliable applications.
