Introdução No processamento de grandes volumes de dados, o uso de streams em Node.js pode trazer enormes vantagens em termos de performance e eficiência. Streams permitem o processamento de dados de forma contínua e em pedaços, evitando o carregamento completo do arquivo na memória. Este artigo explora os benefícios do uso de streams, utilizando um exemplo prático para demonstrar como transformar um arquivo de texto grande de forma eficiente. O Que São Streams? Streams são uma abstração em Node.js que permite o processamento de dados em pedaços (chunks) ao invés de carregar tudo na memória de uma vez. Existem quatro…

Clean Architecture in Node.js: An Approach with TypeScript and Dependency Injection.

stp2y0 CommentsNewsarchitecture, cleancode, coding, community, development, engineering, inclusive, microservices, node, software

A Clean Architecture What is clean architecture and why do we even care about it? The clean architecture approach is a software design pattern and a guideline proposed by Robert C. Martin (Uncle Bob). This architecture urges us to build a cleaner code and more structured code. So why do we care about it, why is it a good fit (at least, for me) to be used with a Node.js project, especially with TypeScript? While there is a catch like a more complex code and it may be overkill for some simple or some quick projects, we have some benefits…

Implementing Secure Multi-Party Computation (SMPC) with NodeJs: A Practical Guide

stp2y0 CommentsNewscoding, community, datasecurity, development, engineering, inclusive, node, securecoding, smpc, software

Introduction In the modern digital landscape, privacy and security are paramount. Secure Multi-Party Computation (SMPC) is a cryptographic protocol that allows multiple parties to jointly compute a function over their inputs while keeping those inputs private. This technology has vast applications, including privacy-preserving data analysis and secure voting systems. In this blog, we'll explore how to implement SMPC using Node.js, making it simple and easy to understand with real-world examples. What is Secure Multi-Party Computation (SMPC)?SMPC is a subfield of cryptography that enables parties to collaboratively compute a function over their inputs without revealing those inputs to each other. The…

Issue with NPM Package Installing Globally

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, node, nodemodules, npm, software

I was not able to install npm packages globally in mac os(using npm install -g), but able to install locally in the project. Installing locally in every project will increase the total node_modules folder size and for every project we need to install the same packages that will be tedious and unnecessary. Here are the steps I performed. I was using Homebrew to install node and npm. So, Used command npm config get prefix - check where the npm actually points to. If this points to /opt/homebrew Check if node_modules are installed in cd /usr/local/lib If (2) is true, brew…

What is Threads and its use in Node.js

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, javascript, node, programming, software, webdev

In the bustling world of computer science, threads are like tiny, independent workers within a larger workshop, a process. Imagine a single process as a factory. This factory has various tasks to complete, from assembling parts to running quality checks. Threads, on the other hand, are the individual workers on the assembly line. They share the same resources (tools, materials) within the factory (process) but can work on different tasks (instructions) concurrently. What are Threads? Threads are lightweight units of execution within a process. They share the same memory space and resources (like CPU time) of the process they belong…
