Tutorials on Node

Find out how to optimize your development workflow when running Create React App and a Node server at the same time.

Serving a web application to a global audience requires deploying, hosting and scaling it on reliable cloud infrastructure. Heroku is a cloud platform as a service (PaaS) that supports many server-side languages (e.g., Node.js, Go, Ruby and Python), monitors application status in a beautiful, customizable dashboard and maintaining an add-ons ecosystem for integrating tools/services such as databases, schedulers, search engines, document/image/video processors, etc. Although it is built on AWS, Heroku is simpler to use compared to AWS. Heroku automatically provisions resources and configures low-level infrastructure so developers can focus exclusively on their application without the additional headache of manually setting up each piece of hardware and installing an operating system, runtime environment, etc. When deploying to Heroku, Heroku's build system packages the application's source code and dependencies together with a language runtime using a buildpack and slug compiler to generate a slug , which is a highly optimized and compressed version of your application. Heroku loads the slug onto a lightweight container called a dyno . Depending on your application's resource demands, it can be scaled horizontally across multiple concurrent dynos. These dynos run on a shared host, but the dynos responsible for running your application are isolated from dynos running other applications. Initially, your application will run on a single web dyno, which serves your application to the world. If a single web dyno cannot sufficiently handle incoming traffic, then you can always add more web dynos. For requests exceeding 500ms to complete, such as uploading media content, consider delegating this expensive work as a background job to a worker dyno. Worker dynos process these jobs from a job queue and run asynchronously to web dynos to free up the resources of those web dynos.

In this article, we will learn how to render a simple React app using an express server.

Sequelize is a promise-based SQL ORM for Node.js, with support to Postgres, MySQL, MariaDB, SQLite, and Microsoft SQL! During this tutorial, we will go through the creation of a simple library database using Sequelize and Node.js system. Models are the soul of Sequelize, we use them to represent the data of our tables, both on a row-level as a model instance, or as a table structure level as a model. Let's create our first model to represent a book in our library. But first using NPM we need to install the following libraries: Let's create a db.js file, to initialize our Sequelize database connection

"Jamstack" is an architecture for web apps that promises to be faster and easier to create than the traditional client/server architecture. In this article, we'll take a dive into the Jamstack architecture to better understand how it works and the advantages it offers. We'll also build and deploy a very simple Jamstack app using Eleventy and deploy it to Netlify .

In this post, we're going to learn how to use Node.js in your Angular app and pass data between the backend and the frontend . Angular Universal provides a tool called TransferState that will help you prevent duplicate data fetching -- it's super handy and a bit advanced. Below is a tutorial that introduces the ideas of TransferState and how to use it, but if you want a step-by-step walkthrough with complete code, then grab a copy of the course . The course is about 270+ pages over 40 lessons that teach every step to creating blazing fast Angular apps. Angular Universal is a powerful tool to address the SEO pitfall of Single Page Applications. Unfortunately, it's not a magic wand, and sometimes you need to adjust your application to make it efficient. Such a problem occurs when your application performs an HTTP call (to the back-end) during the initialization. Does it make sense to perform that call as well in the back-end as in the front-end?

An in-depth look at the Node HTTP module, and how to use it to scale up!

In this article, you'll learn how to create a Node CLI tool to convert a JSON file into a valid CSV file.

Working with dates in a Node app can be tricky as there are so many ways to format and display them. The APIs available in native JavaScript are way too tedious to use directly, so your best option is to use a date/time library. The best known and most flexible option is Moment.js . For this article, I'll presume you understand the basics of JavaScript and Node.js.

Node.js is JavaScript on the backend, built around the highly optimized google's V8 javascript engine. Welcome to the world of asynchronous non-blocking programming.

Axios is a popular JavaScript HTTP client, in this post we will go through some of the most common use cases with Node.

This post is about how Node.Js performs tasks, how and why one would use async methods and why and when one should use sync methods. We will also see how to make use of the new FS. Promises API.
