AWS Serverless Web Application tutorial

Tue, 18 Aug 2020 06:42:26 +0000

Intro to AWS Serverless Web Application tutorial

Today we’ll go throught AWS Serverless Web Application tutorial.

Nowadays, almost every industry actively uses IT. We build web and mobile apps, manufacturing applications, e-commerce, and even software to handle factories.

Development is not an easy process, costs a lot of money, very often it is stressful, and still, it’s not all that we need to handle.

Most of our IT solutions need maintenance, and IT infrastructure to handle our software.

How to build GraphQL API tutorial - Express.js course Lesson 1

Tue, 07 Jul 2020 06:42:26 +0000

Intro to how to build GraphQL API tutorial

In the first lesson of the Express.JS course, we’ll focus on building a GraphQL API tutorial with typescript.

Express.js is one of Node.JS’s most popular frameworks, which helps us create a backend for our application with the usage of Javascript or Typescript.

It’s convenient because we can do full-stack development with only knowledge of the Javascript.

Don’t worry if you don’t know Javascript yet, we created a course that will help you learn that excellent programming language.

Kotlin course with building Android AR app - Lesson1: How to setup Android Studio and ARCore for an augmented reality project

Today we will start the Kotlin course, where we will build the Android augmented reality mobile app. As most of today’s lessons, we will learn how to setup Android Studio with ARCore for augmented reality projects.

Kotlin programming language is one of the most popular now.

Kotlin is similar to Java and strongly cooperates with that language, but I would say, Kotlin gives us much bigger opportunities.

In Kotlin, we can build not only back-end but also cross-platform mobile applications, work with data-science, do pure android development, and even do web development.

Flutter Course, building a fintech mobile app – Lesson 1: Login form

Mon, 15 Jun 2020 15:42:26 +0000

Intro to Flutter Course

Flutter is a framework to build mobile applications for Android and iOS using Dart programming language. Flutter was made by Google developers, and now it’s the main competitor of React Native.

As a front-end developer, I’ve already worked with React Native, and I have an idea of how it works, but Flutter was a mystery that I wanted to discover. So, I did, and that’s why today I’d like to show you how cool Flutter is, and how comfortable it’s to work with this tool.

Today, it’s time for lesson 4, where we will handle user registration.

If you didn’t start with me, feel free to go through all the lessons until now. Or you can get the code from the previous lesson and jump straight to this lesson. Here’s a link to our Github repository for this Angular Course.

So, if you were creating the application with me in the previous part, then let’s open the code and start the app. If not, check out the Angular Course – Lesson 1: Start the project or check out our GitHub and get the code from there.

We decided to create a full Angular course with Angular 9, where we’d like to teach you how to create front-end for the fin-tech application like the one in SQL injection example.

We are going to start by creating a new project with Angular CLI, installing Tailwind CSS for the UI, setting a proxy, and building Login component UI.

How to build dashboard with Bootstrap tutorial

Sat, 22 Feb 2020 08:00:19 +0000

Would you like to create websites from a ready element? Bootstrap is one of the most popular CSS frameworks. It allows us to build a beautiful UI from ready components, like navbars or forms. Bootstrap also provides a responsive design so, while using the grid properly, you don’t have to do additional styling for mobile views.

For advanced developers, CSS frameworks seem to be simple because it’s mostly about reading the documentation, but beginners sometimes may have issues building projects from Bootstrap components. That’s why I decided to create this tutorial and build a simple dashboard, with step by step explanation.
