![]() This course is designed by Jonas Schmedtmann. Especially, these testing sections that you would not found generally in other courses.ģ) Node.js, Express, MongoDB & More: The Complete Bootcamp 2020 It also comes with concepts like error handling, unit testing, and integration testing. It also includes how to built RESTful APIS from scratch. It is also packed with great content that includes basics like how node js architecture, how node works etc. If you want to learn NodeJS fundamentally you can follow this course. This course is designed by a wonderful teacher named Mosh Hamedani. You can go to the course by the following link:Ģ) Node.js: The Complete Guide to Build RESTful APIs (2018) I personally learned NodeJS by following this course. This course is packed with great content that starts from level zero to more advanced topics. I highly suggest that you should definitely start with this course. This course is designed by an amazing teacher and experience web developer Maximilian Schwarzmüller. Now, let me walk you through the courses for becoming a very sound NodeJS developer.ġ) NodeJS - The Complete Guide (incl. I will not go into details as it is not for that. But there are many advantages of NodeJS over these technologies. You can become a Backend developer by learning other technologies like PHP, Python(Django), Ruby(Ruby on Rails). So I think, it is a great choice to become a Backend developer. As you can see everything needs to have backend for maintaining so many things under the hood. Backend is essential in any kind of application like a web app, mobile app, desktop app, etc. Let me first talk about why you should be a backend developer. If you want to become a Backend developer in 2020, then NodeJS would be a great choice as it is dominating the space of backend development currently. Public static getInstance(): DBConnection. Private static instance: DBConnection | null = null Now upon every request, we will get the same instance. In this case, a single DBConnection exposes static instance of the class through getInstance(). Returning the same instance on every request.Restricting the creation of a new object.Think about initializing a database connection. In this case, there is a single wifi connection being consumed by multiple members. Wifi router is shared by all the family members. Think of singleton pattern as global variables on steroids without unintentional manipulation. Irrespective of that Singleton pattern which stands for singular instance provides an elegant way to handle such a situation. The reason could be either performance implications or resolving concurrency problems. Sometimes we want to restrict the total number of instances that can be created of a particular object. Let’s look at the most popular pattern within this category. It not only enforces a structure but also avoids unnecessary manipulation while creating an object. ![]() Let’s take a deep dive into each one: Creational patternsĬreational design patterns are concerned with improving the process of creating Objects. Now that I have convinced you about why you should learn design patterns, let’s look at the most popular patterns which you should know in 2022!Įven though new design patterns are being added every day, all these patterns belong to 3 major categories: And it’s the most popular interview question, especially for senior roles.It makes maintenance of code easier by keeping your codebase in check with SOLID principles.It also reduces onboarding time to a new codebase as design patterns transcend particular programming language.As a developer, implementing solutions that use design patterns will save you hours of debugging time by making your code robust & reusable.So why should you care about learning design patterns? Over the years I have seen that there is one thing that separates a seasoned developer from a freshman: the extent to which they use Design Patterns!ĭesign patterns are tried and tested holy grail of solutions to the most common code design problems which have stood the test of time.
