Added Static File Handler

[KedarisettiSreeVamsi]

Added Static File Handling
If a public directory is found then it will create a public endpoint by default
If we want to added any other folders can use AddStaticFiles endpoint and then if endpoint and directory is provided then it will check whether the particular endpoint is available otherwise throws an error

Closes: #502.

Let me know if any changes can be done to accommodate more functionality.

@KedarisettiSreeVamsi Thankyou for your contribution.
Please add consider adding tests for any new code added as not doing it will decrease the overall code coverage.
Also, in my opinion we don't actually need an example of how to serve static files. Your example is small and simple so a better way is to add a documentation for this.

You can add it in the advanced-guide directory under the docs directory of the repository.

Small typo

@KedarisettiSreeVamsi please add unit tests for the feature you've implemented!
Please fix the linters also!

[KedarisettiSreeVamsi]

Hi @vipul-rawat,
Can you please mention how I can write unit tests without a static folder in the same folder as test file? Should I use a file within the folder for the testing purpose?

[KedarisettiSreeVamsi]

I am pretty new to this so was the reason I am asking this question.

[vipul-rawat]

@KedarisettiSreeVamsi I think we can create a tmp folder and when cleaning up we can remove all the tmp files created!

LGTM 👍

Can someone resolve the conflict of docs/reference/configs/page.md as it is blocking all the tests? I tried to fix it but unfortunately it Is not getting fixed.

1. Remove helper and constant files. (fixed)
2. Lot of lines are not covered (coverage is not 100% for the newly added code)
3. ExcludeFiles need to be unexported (we can move the code to add openapi.json in the router itself) (fixed)
4. FileDirectory needs to be renamed, doesn't seem right
5. ExcludeExtensions, HideDotFiles can be removed for now, I dont find a valid usecase. (IMO user can just not keep that file if they dont want it to be rendered) (fixed)
6. DirectoryListing can be renamed to ListDirectories or ListDirectoryFiles
7. A lot of functions/methods are being exported which can be unexported (fixed)
8. .env Config STATIC_DIRECTORY_LISTING can be removed (fixed)

Seem safer and avoid potential breaking changes 👍
