Shortcomings of Node.js
- Bad concurrency primitives
The programming language is entirely built on top of the ground of asynchronous I/O. Being a single-threaded platform intensive on I/O bound applications on highest of a language that does not pledge transparency and has no support for co-routines, this is an explicable select. It is much superior than heavy weighted threads with shared states, but it is a poor model of concurrency to expose to the platform.
- It is Single – Threaded
Being single threaded, it means that one does not need to care about the problems of synchronizing between threads, or shared mutable state. However, it also means that unlike preemptive concurrency, the programmers themselves have to resolve how to pact with concurrency, with the avoidance being no concurrency at all.
- js lack maturity
- It is reliance on stringly-typed programming
There is a flourishing of “strings are easy” in the open, which hints to many bugs due to futile dependence on strings, rather than fitting data structures.
- It is hard for Node.js to make things fault-tolerant
They don’t give all of the tools that are necessary to make systems reliable and fault-tolerant, as OTP/Erlang does. There are no mechanisms to handle or recover from errors that are thrown asynchronously.
- js deficiency of intrinsic code organization is a giant disadvantage. It gets especially worsened when the development team as a whole isn’t accustomed with asynchronous programming or standard design outlines. There are just too many ways for code to get disruptive and unsustainable.
- js development service is wonderful, and has excellent chance of becoming the gold standard. But as concerned with the disadvantage, the Node API has a habit of changing in backwards-incompatible methods from release to release, and recurrent alterations to your codebase are obligatory to keep things running on the up-to-date version.
- Node’s biggest problem at the moment is the amount of duplication of effort taking place when it comes to the network of packages & the expanse of effort paid the best package to use for any agreed task that stems from this.
It really depends on what you’re trying to do with your web app. If you are doing a lot of I/O bound tasks then Node.js is just fine. However, if you find yourself doing a lot of CPU bound tasks than you are enhanced off using Java or whatever JVM language you desire because doing CPU bound tasks in Node.js will wedge the event loop.
