How to perform Api Deploy with Composer / SlimFramework

The way you have organized folders and index.php , is to send the contents of the BackEnd folder via FTP to the root folder of the HTTP server.

On SHARED and VPS servers it is usually the public_html folder, sometimes htdocs or www

It is not necessary to send the git (and nor should ) folder, also note that perhaps the vendor folder and class folder would be better off public_html ), because eventually depending on what is put in them there is a remote possibility that something can be executed when it should not, which can cause problems, such as BUGs or even possibly some security flaw.

However if you have been installed via the skeleton command line with composer , for example:

composer create-project slim/slim-skeleton [pasta-projeto]

The root folder would be public , so the schema to use would be more or less this:

/home/user/
   |--- /vendor
   |--- /class
   +--- /public_html     (pasta padrão em servidores com cpanel)
          |--- index.php (arquivo da pasta [pasta-projeto]/public)
          +--- .htaccess (arquivo da pasta [pasta-projeto]/public)
