Connecting to MongoDB in Node.js Using Singleton

⭕ Overview Hello, everyone! Today we will talk about a very important design pattern in software development called Singleton. This is designed to ensure that only one instance of a class or a function will be created, providing one access point to it across your entire application or even to multiple servers. In this video, I will be explaining the basics of this pattern to you—how it works and why it is very important in most programming situations. By the end of this tutorial, then, you will confidently know how to implement and use Singleton in your projects.

Thank you for watching! ⭕ Chapters 0:00 - Introduction In this video, I'll address a question that came up during our class last night: how to build a matrix or table using code instead of creating it manually. I'll demonstrate the process step-by-step to ensure you understand how to automate the creation of matrices. Additionally, I will expand on the solutions we discussed in class by exploring how to calculate the diagonals of a matrix to check if they are equal. This involves more advanced manipulation and computation within the matrix, providing deeper insights into its structure and properties. Join me as I walk you through these coding techniques, explaining each part in detail to enhance your understanding. Whether you're new to matrix operations or looking to refine your skills, this video will provide valuable knowledge and practical applications. ⭕ About me I am a Web instructor and author for Linkedin Learning (formerly Lynda.com), Packt, E-C Council, Udemy, and MC Press. ⭕ Visit my site: https://christianhur.com ⭕ My complete online training courses: ☑️ REST APIs & AJAX Operations Using Node, Express, and jQuery: https://www.udemy.com/course/rest-api... ☑️ Build Clean and Secure PHP Web Apps From Scratch: https://www.udemy.com/course/build-cl... ☑️ Angular 9 New Features: https://www.packtpub.com/web-developm... ☑️ Full-Stack Web Development with Flask: https://www.packtpub.com/web-developm... ☑️ Full-Stack Web Development with Django & Angular 8: https://www.packtpub.com/web-developm... ☑️ Angular 7 New Features: https://www.packtpub.com/web-developm... ☑️ The DOM in JavaScript, jQuery, AngularJS, and React :   / the-dom-in-javascript-jquery-angularjs-and...   ☑️ Building JSF Web Applications with Java EE 7:   / building-jsf-web-applications-with-java-ee-7   ☑️ Troubleshooting Vue.js: https://www.packtpub.com/application-... ⭕ Check out my book: Developing Business Applications for the Web: With HTML, CSS, JSP, PHP, ASP.NET, and JavaScript is available on Amazon and MC Press. ☑️ Link: https://www.mc-store.com/collections/...
