I am working on customizing the oracle service cloud customer portal, but since OSvC provides only WebDAV to connect to it. It is very time-consuming to edit files and then upload them to WebDAV even for a single word change. I am looking for a solution to serve it locally make desired changes and then upload the desired code to webDEV.
But after searching the file structure I can not make which framework it uses, I tried to use websites like https://builtwith.com/ and WhatRuns but they are also not able to find anything useful.
Although after searching in the file structure, I find some files of CodeIgnitor but the structure is way more different than the CodeIgnitor folder structure.
The short answer is no, you will not be able to run Customer Portal locally. While it is a fork of CodeIgniter from many years ago, there are server-side dependencies that will prevent you from running it in a local sandbox.
That said, it is possible to automate many of the manual tasks of interacting with WebDAV for change testing. If you edit locally, then you can use scripting hooks or event RPA robots to automate some of the manual file movement. Personally I have a flow to edit remotely in my test environment with an editor (like VSCode or Nova) that can connect to a remote server via WebDAV and edit files directly in the development area of a site. Then, when finished, I have a script that pulls down the latest version of all files and then allows me to commit changes to Git for SCM.
Another option is RPA. You can develop a robot that can be run to automate the manual tasks that you face in your workflow. Personally, I think that scripting is a better solution than RPA since you can automate all of the actions via scripting or a shell. But, it's another option to consider.
