Is it possible to make a turnkey website on cms without knowing the backend?

Question

Backend

I know the frontend well, but now it’s hard to find freelance orders purely on the frontend(s). Is it possible to master csm relatively quickly and make up various sites (business cards, shops, etc.) of average complexity on a turnkey basis without knowledge of the backend (php, etc.). If possible, what resources would you recommend, etc. for quick learning. If not, then what is the minimum knowledge in the backend required for such activities.

Answer 1

I know frontend well

Sure?
There are over 1800 results on React alone on upwork.

Answer 2

If the client's wishes fit accurately enough into the finished functionality of the CMS and modules, then it is possible. But when a client wants a feature that is not there, even a very small one, you will either have to crutch or look for a performer.

Answer 3

Team up with some back developer who works for food and delegate some of the tasks to him. Preferably from your city, in order to be able to activate its activities in case of "illness".

Answer 4

Wordpress - for simple sites
Opencart - for shops

Answer 5

Turnkey yes. Accompany, update, etc. - No.

Answer 6

Theoretically - it is possible. In practice, at the first slightly non-standard problem, you will have to turn to a familiar backender.
So I would advise:
1) Since you are already well versed in javascript, then it will not be difficult for you to master the basics of PHP (variables, loops, arrays) by analogy. Deep knowledge of PHP is not required (SOLID, patterns, flows, traits, etc.).
2) Learn to write SQL queries, at least simple ones. No, when developing directly, you won’t have to write them, because almost every CMS has its own API that emulates these requests, but it’s useful to know what exactly, what types of connections this API emulates.

Answer 7

Can.
Moreover, you can write your own SPAs based on the WordPress backend using the Wordpress REST API.
You need to know the basics of the backend and the principles of its work, but no more.
You don’t need to deal with backend and frontend in parallel, it’s better to do one thing, but do it well.

Answer 8

You can make another shitty site, but not a real one for the client.

Answer 9
