Advantages of Choosing Node.js
- Node.js is an open source runtime environment that supports caching of individual modules.
- Concurrent request handling is assisted by the asynchronous event-driven IO.
- Both the server and the client-side uses the same piece of coding and as a result, it makes things easier for businesses to deploy the various web applications more effective.
- Node.js has an active and vibrant community with codes shared regularly via Github, etc.
- Being a single-threaded program, Node.js has multiple options for having a good control over run-time executions like event-loops and call-back methods.
Disadvantages of Choosing Node.js
- The main drawback is the consistency factor. Many Node.js development companies feel that the API keeps changing at frequent intervals.
- Node.js don't work well with relational databases.
- Node.js requires an asynchronous programming approach for it to enhance its scalability. This has a split opinion among developers as many feel that this particular approach is more complicated than the linear blocking I/O programming. This also makes the code look messy.
- Node.js is not suitable for large and complex web applications as it, at present doesn't support both multi-threaded programmings.
- Programmers find it hard to use Node.js for high intensive computational tasks.
