Node.JS and Faster Data Manipulations

What is Node.js?

Node.js is a JavaScript engine (V8) programming environment. It is used to compile JS code into machine language. In other words, this software platform translates source JS directly into machine code, which will be executed on the server side. It is important to clarify: Node.js is not a standalone programming language but only a software platform for using JavaScript on the server side. At the same time, it uses event-oriented, and so-called react programming approaches. Nod is often used as a web server; however, it can also be used to create desktop programs and other purposes (for example, for programming microcontrollers). This platform appeared in 2009 and is used widely in various development industries. By type of software platform, it refers to runtime environments.

In simple words, Node.js is a platform that can compile JavaScript code directly to native code. Thus, the conversion of the source JS into a general-purpose language is achieved.

What is Node.js needed for?

First, let’s clear up two crucial points: what is Node and what it is not.

What Node is NOT:

  1. It’s not a framework, and it’s a server.
  2. Node wrappers over JavaScript V8 Runtime made not in JavaScript but in C language.
  3. It’s not multi-threaded. It runs on the same thread with a callback.
  4. It is only for beginners who know how to work with JavaScript.

What is Node:

  1. This is a server that can execute JavaScript. It is a browser on the server side.
  2. It is a cross-platform for deploying real-time web applications.
  3. It provides you with asynchronous APIs (driven by I/O-type events)
  4. It starts a single-threaded event-based loop, so all executions become non-blocking.

The Nod platform is used for server-side programming. Most often, its code is used to create web applications, sites (and web pages); in addition, it is used to deploy command line programs.

The software platform is used for any backend development related to the JavaScript programming language. But front-end developers also use this platform to solve their problems.

Node.js is a complete JS runtime that allows developers to build scalable applications of almost any complexity. Web development is the main specialization of Node.js.

Here is a short list of examples of what can be done with Node.js:

  1. Desktop program for various operating systems, including Windows, Linux, DOS, UNIX, and macOS.
  2. Cross-platform program
  3. Online service
  4. Social network
  5. Online game
  6. Any site

Advantages of Node.js

  1. Asynchronous event-driven I/O helps in processing requests concurrently.
  2. The same piece of code can be used both on the server side and on the client side.
  3. Uses JavaScript that is easy to learn in a few months
  4. There is NPM. This is a native module package for Node. Everything is there, and it continues to grow.
  5. An active and lively community with much code distributed through GitHub and other developer sites.
  6. You can transfer large files.

Disadvantages of Node.js

  1. Node.js does not provide scalability. One processor will not be enough; however, the platform does not offer any scalability to take advantage of the multi-core features commonly found in today’s server hardware.
  2. Working with a relational database – turns into a big headache if you use Node.
  3. Every time you use a callback, tons of nested callbacks is generated.
  4. With a deep dive and knowledge of JS, one can avoid a conceptual problem.
  5. Node.js is not suitable for CPU-intensive tasks. It is only suitable for direct I/O (for example, web servers).

Where Node would be the best solution

Here are a few applications or areas where Node.js can be the best tool:

  1. WebSocket servers. The non-blocking architecture makes Nod the best tool for deploying WebSosket or streaming applications. Chat servers can become more efficient, faster, and more polished using Node.js as a foundation (because such servers work in real-time mode, where response speed and data transfer are critical).
  2. Client for fast file upload. With Node, you can upload multiple files at the same time. This means that at the same time, a Primer1 file part and a Primer2 part can be on the server. This approach does significantly speed up the speed of downloading files.
  3. Streaming data. Because Node deals with the callback concept, it can also be used for streaming data. This can be very useful for various purposes, especially for businesses (for example, product aggregators get results from several third-party APIs at once).
  4. Advertising server. Ad servers should be the fastest. If the ad on the site loads faster than the main content, then the user’s immediate attention will be received by the advertising banner. Another thing is if the ad loads more slowly: you have a large banner before content that takes 5 seconds to load. And while such an advertisement is being loaded, the user will already begin to read the middle of the page. Therefore, ad servers need to be fast, and that’s why you need to use Node.
  5. Stock exchange software. This is a specific example. And he well illustrates the possibilities of Nod. In the case of stock updates, everything should happen in real-time. Node makes it possible to deploy web applications that communicate efficiently in real-time.

How Node.JS is used for faster data manipulations

Node.js provides several features that make it well-suited for faster data manipulations.

First, its non-blocking I/O model allows for the efficient handling of large volumes of data. Asynchronous programming patterns can be used to avoid blocking the event loop and ensure that other operations can continue to execute while data is being processed.

Second, Node.js provides built-in modules and third-party libraries, allowing efficient data manipulation. For example, the Buffer module offers a way to work with binary data in a performant way. 

Third, Node.js allows for parallel data processing through worker threads or the cluster module. This allows multiple lines to work on different parts of the data simultaneously, improving performance for data-intensive tasks.

Overall, Node.js provides a range of tools and features that can optimize data processing and improve performance for data manipulations.

What is GraphQL

GraphQL is an open-source query, data manipulation language, and runtime for APIs (Application Programming Interfaces) developed by Facebook in 2012 and released as an open-source project in 2015. It was designed to provide single endpoints for data, allowing applications to request precisely the data they need. This has the benefit of not only simplifying our UI code but also improving performance by limiting the amount of data that needs to be transferred over the wire. GraphQL has become used by many other large and small companies. Others include Yelp, Shopify, and Github.

With GraphQL, clients can send a single request to the server that specifies the data they need, and the server responds with exactly that data. This is in contrast to traditional REST (Representational State Transfer) APIs, which often require multiple requests to the server to retrieve related data.

GraphQL also provides a robust type system that allows for easier development and integration with modern development tools. It also provides features like real-time updates, caching, and error handling.

Overall, GraphQL provides a more efficient and flexible way to interact with APIs and has become increasingly popular in recent years as a replacement for traditional REST APIs.

When using REST APIs, requests are usually sent to multiple addresses to get all the necessary data in the application. The GraphQL API, on the other hand, allows you to send an entire request to an address indicating what kind of data you would like to receive with this request. Therefore, GraphQL is excellent when used on a slow mobile connection.

API versions can be a headache for development teams. With GraphQL, you don’t have to worry about that. GraphQL allows you to add new fields and types (this will be discussed later) to your GraphQL API without affecting existing queries, while old and unused fields can be hidden from API clients. Using a single evolving version, GraphQL APIs provide your application with constant access to new API implementations and provide a clean and easily maintainable code base.

How to use GraphQL with NodeJs

To use GraphQL with Node.js, you can follow these general steps:

  1. Install the necessary packages: You’ll need to install the GraphQL package to define your schema and resolvers and a server framework like express to create an HTTP server.
  2. Define your schema: In GraphQL, you define a schema that describes the data that can be queried and the operations that can be performed on that data. This can be done using the GraphQL Schema Definition Language (SDL) or programmatically using the GraphQL package.
  3. Implement your resolvers: Resolvers are functions that define how to fetch the data requested by a query. You’ll need to create resolver functions for each field in your schema.
  4. Set up your server: Use your server framework (e.g., express) to create an HTTP server that listens for requests and sends back responses. You’ll also need to set up a route for handling GraphQL queries and mutations.
  5. Test your server: You can use GraphiQL to test your GraphQL API by sending queries and mutations to your server and seeing the results.

There are many resources available online that provide more detailed information on using GraphQL with Node.js, including tutorials, documentation, and sample code.

What to use GraphQL with NodeJs for

GraphQL can be used with Node.js for a wide range of use cases, including:

  1. Building API backends: GraphQL provides a flexible and efficient way to make API backends that can be used by various clients, including web and mobile applications.
  2. Real-time data updates: GraphQL supports real-time updates through the use of subscriptions, which can be used to push data updates to clients as they happen.
  3. Data aggregation: With GraphQL, clients can request data from multiple sources and receive a single response, making it ideal for aggregating data from different APIs or microservices.
  4. Caching: Because GraphQL allows clients to specify the exact data they need, it can be used to optimize caching and reduce unnecessary requests to the server.
  5. Mobile development: GraphQL’s flexibility and efficiency make it well-suited for mobile development, where network bandwidth and device resources can be limited.

Overall, GraphQL provides a more flexible and efficient way to interact with APIs and can be used for a wide range of use cases in Node.js applications.

How GraphQL with NodeJs can help work with data twice as fast

GraphQL with Node.js can help work with data twice as fast in several ways:

  1. Reduced network traffic: With GraphQL, clients can request only the data they need, which reduces the amount of network traffic required to transfer data between the client and server. This can result in faster response times and reduced network latency.
  2. Efficient data fetching: GraphQL allows clients to request multiple resources in a single query, which can be more efficient than making multiple requests to fetch the same data. This reduces the overhead of repeated network requests and can improve performance.
  3. Simplified API development: GraphQL’s flexible and strongly typed schema definition language can reduce development time, making it easier to develop and maintain APIs.
  4. Reduced over-fetching and under-fetching: Because clients can request only the data they need, over-fetching (receiving unnecessary data) and under-fetching (not receiving all the required data) can be reduced. This can optimize performance and reduce the processing time needed for data manipulation.

These benefits can help to improve the performance and efficiency of data processing in Node.js applications, allowing developers to work with data twice as fast as they would with traditional REST APIs.


In conclusion, GraphQL with Node.js provides a flexible and efficient way to work with data in modern web applications. GraphQL’s strong typing, flexible schema definition language, and efficient data fetching make it an ideal choice for building APIs that can be used by many clients, including web and mobile applications.

By allowing clients to request only the data they need, GraphQL reduces network traffic and processing time, which can improve performance and scalability. Additionally, the ability to request multiple resources in a single query minimizes the overhead of repeated network requests, making data processing faster and more efficient.

Overall, GraphQL with Node.js provides a powerful combination of tools and features to help developers build modern web applications that can work with data more quickly and efficiently.
