I would like to learn Server side rendering and while searching in google,i've seen many topics about a framwork called nextjs,and after trying it,i found it pretty good.SO now i would take a serious course on SSR,but after a search on Udemy I've found a course which is rated 4.7/5 of Stephen Grider,but in the course content i've not seen next.js.Here is the course link : Server Side Rendering with React and Redux.
I don't have much experience with SSR,but it seems that there are two ways to make it:With React,redux,node/express or Next.js.
When i've tried next.js,i've not used react-router but in the description of the courses of udemy,the instructor talks about using react router.
I really need your advices before i learn it seriously,and i need to know the best solution between the 2 approches.
