Characteristics of Node.js
The features that make Node.js the primary choice of software architects are listed below.
- Node.js uses a single-threaded structure with event looping, making it very scalable. In contrast to typical servers that create limited threads to process requests, the event mechanism allows the server to reply in a non-blocking manner and makes it more scalable. Node.js uses a single-threaded program and the same program can provide service to a much larger number of requests than traditional servers like Apache HTTP Server.
- There is no data buffering in Node.js apps. The data is output in chunks by these apps.
- The MIT license governs the distribution of Node.js.
Where to Use Node.js?
The areas where Node.js is proving to be an excellent technology partner are as follows.
- I/O bound Applications
- Data Streaming Applications
- Data-Intensive Real-time Applications (DIRT)
- JSON APIs based Applications
- Single Page Applications
Advantages of Node.js
1. A solid technological foundation
- Improved developer productivity and efficiency
- Code reuse and sharing
- A large number of free tools; speed and performance
- Easy knowledge sharing within a team
2. It is not a misconception that Node.js is quick. Check out toptal.com’s performance tests to see how GO, PHP, Java, and Node.js handle concurrent queries.
3. Microservices and scalable technologies
Node.js for microservices architecture is a beautiful choice because it is a lightweight technology platform.
4. A diverse ecosystem
5. Corporate support is vital.
6. JSON support is seamless.
Disadvantages of Node.js
- Heavy calculation activities cause performance constraints.
- Issue with callbacks
Because of its asynchronous nature, Node.js mainly relies on callbacks, which are routines that run whenever each task in the queue has been completed. Keeping a multitude of queued activities running in the background, each with its callback, can lead to callback hell, which directly influences code quality.
- Tooling immaturity
Even though the core Node.js modules are relatively stable and mature, numerous tools in the npm registry are either of poor quality or are not adequately documented/tested. Furthermore, the registry isn’t well-structured enough to allow users to search for tools depending on their rating or quality. As a result, if you don’t know what to look for, finding the ideal solution for your needs could be challenging.
- Demand for skilled workers is increasing.
Node Package Manager
The Node Package Manager (npm) offers the following two primary features:
- Node.js package/module repositories that may be searched on search.nodejs.org
- Install Node.js packages, control their versions, and manage dependencies with this command-line utility.
Uses of Node Package Manager
- When used as a dependency manager for a local project, Node Package Manager may install all of a project’s dependencies via the package in a single command.
- Each dependency can designate a range of valid versions using the semantic versioning system in the package.json file, allowing developers to auto-update their packages while avoiding unnecessary breaking changes.
- Developers can use Node Package Manager’s version-bumping tools to tag their packages with a specific version.
- After reviewing semantic versioning in package.json, Node Package Manager additionally delivers the package-lock.json file, which contains the entry of the precise version utilized by the project.
