Let’s go in pieces.
1- I noticed that to run the angle, you usually use Node for backend apps for example. I saw that you can create layouts with the angular, so, how do I run a project by Chrome? (eg export the proj to a server without Node)
You need a WEB server to publish the application. The angular application could stay hosted on an apache server even.
As for the use of Node in the backend, it is not a requirement, in my previous company we used angular and C# in the backend, it is a question that depends on the need of the company and choice of the language of the company, the angular frontend has nothing to do with the language chosen for the backend.
2-Using angular and Node, PHP would no longer need in a project?
Yes, if you use Node in the backend PHP is expendable, but if you prefer you can create a project with PHP in the backend and the angular in the frontend, you just have an API. Same if you want to use C#, Java, Python, Ruby, etc.
3- With these 3 languages, whereas I am average in javascript,
where I should begin?
Learn javascript first and then study the framework, be it angular, React or any other.
After learning javascript well, create a focus for you, if you prefer to work with frontend, start studying the angle, if you like the backend more, study Ode.
Good morning, from a searched in Mean stack, is an alternative vc do everything with angular, Node, etc..
