What should be the file structure of the website on Yii2 and AngularJS?
A small website on Yii2, template basic.
One of the sections (one controller) I want to do with Angular 1.x
I.e. partly regular site, partly api.
Where in this case the rest of the Angular files?
If the site is completely done as an api, you know that it is easier for the backend and the client spread across different domains.
Depends on what address You plan to run Angular.
For example a folder somepage which lies at the root public folder of your site.
You do not need that Angular has run through yii. yii only as an api to receive requests from Angular to handle, to do something and return.
