Sequelize is a powerful Object-Relational Mapping (ORM) library for Node.js that allows developers to interact with databases using JavaScript. It provides a simple and elegant way to define and manipulate data models that map to relational database tables.
Search functionality is one of the most critical features of the modern web. It enables visitors to quickly and easily find information they are looking for without having to figure out how items are categorized on your page manually.
When developing applications, logically we do throw errors or raise exceptions from time to time when things do work as expected. For instance, trying to make a network request to an external API from your application resulted in an error, let's say an INVALID API KEY error or database connection error, this error can be caught and reported by our application with detail using Sentry for your attention to be drawn to it in other for it to be fixed immediately.
Hey, guys! Our today’s article will tell you about Node.js timers. Here we will try to tell you about all the differences existing between browser and Node.js timers. So, let us refer to our technical materials and see a number of similar methods:
In this article, we’re going to demonstrate how we can set up Authentication/Authorization with Hasura and Auth0. First, we’ll set up the Auth0 application, API, and rules.
This lesson will continue the last lesson where we learned how the LibUV library works internally. In this lesson, we will learn about Event Loop and understand various terms like call stack, callback queue, etc. Let's start.
Hello everyone, today we are going to talk about the internals of Nodejs. This article will guide how node js works and how it can handle async tasks. What will happen if ten requests come at once? Will it handle one request and discard the other 9? or will it create a queue and serve each one by one. We will answer all these questions in this and coming lesson. Let's start.
Nodejs is JavaScript cross-platform runtime environment. When it comes to building a simple HTTP server for a project, building with nodejs, is simpler and lighter. This is because you don’t get to introduce external modules, built-in node modules.
When building any scalable application, performance, as well as speed, are important factors to consider. Hence optimization is crucial. There are numerous optimization techniques you should consider when working with GraphQL servers, but the most common is the caching technique which returns persistent data, and also the batching technique which reduces the number of round trips your server makes to the database.
Asynchronous Operation refers to the flow of execution when something doesn't follow the line by line execution of code but waits for some time. Set timeout is a general of an asynchronous task. What happens when you create a timeout task?
