Description

Would you like to be able to create a basic blog in under 10 minutes? If so, then this course is for you!Symfony is an amazing modern PHP framework. Modern, but not new. It has been there since 2005, so majority of its childhood problems have been solved long ago. During my career I’ve worked on projects build in Laravel, Cake, CodeIgniter, Next.js, Spring and many more frameworks in various languages. But Symfony is the framework of my choice.In this beginners / intermediate course, I am going to show you how to get started with Symfony Framework. I assume you have no prior experience with Symfony, but some knowledge of PHP is required. This course is also kept updated to the most cutting-edge Symfony versions, so even if you are an advanced developer - I believe you will find something for you here too!This is a hands-on course, so not only will I show you the most fundamental concepts of Symfony, but also we will work on a real-world app. We will build a weather forecast system. First as a monolithic website, and then as a backend API, which can be consumed by React, Vue or Vanilla JS apps.Why to purchase this course? While the documentation on Symfony website will show you all possibilities that the framework offers, in this course I am going to point you to the ways which actually work best. However, I would also like you to get your own opinion on this and other frameworks, so close to the end of the course, I’m going to show you how to achieve similar effects using Laravel and Next.js.Symfony keeps evolving, and so does this course. When something changes in Symfony, I’m going to create new videos and replace relevant parts of the course. So enroll once and learn continuously.Currently supported version: 6.3.
