Intro to Angular Course - User authentication For almost one month, we are preparing an Angular course for you, and we are building a fin-tech application. Today I’m going to show you how to implement user authentication and how to use it with guards and resolvers. Our main goal is to check if the user token is active and compatible with the user id. When it’s correct, our API will return us the user data, and the user will be able to see the dashboard.

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.

In the previous week, I’ve published the second lesson of the Node.js Course, where we created registration and saved new users in our database. If you would like to be updated, feel free to go back to the lesson one and follow up or get the first lesson code from our Github. Today I’m going to refactor the code we’ve created for user registration to create a response which our API will send as a result.

For almost three weeks, we are creating an Angular 9 fintech application together, step by step. We’ve already gone through the setting the project and creating a login form template, then we’ve created the logic for our login form, and last week we displayed user data in the template. 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.

Intro Today I will show you how to write a resume for an IT job.

Intro to Node.js Course – Lesson 2: User registration In the second lesson of the Node.js Course, we are going to create a user registration. In the previous week, I’ve published the first lesson of the Node.js Course, where we started a project using Nest.js, Nest CLI, PostgreSQL database, and Sequelize. Besides that, we managed to create migrations and set up the database. So, if you would like to be updated, feel free to go back to lesson one and follow up or get the first lesson code from our Github.

Intro In the third lesson of the Golang course, I will show you how to build user registration in Golang.

Link is here: SQL Injection attack tutorial for beginners Today we will focus on something else, but still dangerous, and quite easy to do.

This article is the first lesson of our Node.js course. The previous week, I and my friend started to build a project divided for two courses – backend with Golang and frontend with Angular 9. In the meantime, we got the idea to give you an alternative for a Golang course, and show you how to build a similar backend using Node.js. In this article, we are going to start by setting up the Nest.
