Remove old files from S3 subfolder before upload new ones

[make-ing]

Is your feature request related to a problem? Please describe.
I am using ngs-aws-deploy now for some time and my S3 folder is starting to get filled with old build files from previous versions of my SPA. Because Angular is creating the files with some sort of random indetifier to prevent caching, the "old" files dont get deleted when i deploy the new version.

Describe the solution you'd like
The deployment script should delete all files currently in the subFolder and the upload the new ones.

Describe alternatives you've considered
Add an option to enable the deleting of the old files before the upload of the new ones.

Additional context
N/A

Hi @make-ing, I'm not completely sure if we should support this feature. I see some problems when you have a bucket with multiple folders and accidentally you switch the flag (but maybe that is just me). However, did you know that you can use ng build --output-hashing none this will allow you to always have the same names and not the unique names that are generated by the Angular CLI. Maybe this is a quick workaround for you? Let me know what you think.

I will add a discussion tag on this issue so that people can comment if we should add this to the library.

First of all. Thank you for your response. It is not normal nowadays to find a good and well maintained project. Or its just me finding not the right ones.

I thought of removing the hasing as well, but its actually very usefull to counter the problem of caching and stuff. For now its not a big Problem, but i realy would like to have such a feature. Maybe you can add a confirmation input when the flag is used?

I would use the flag if you added it. Thanks for this great project btw!

I'm adding a tag for help wanted is one of you interested in making a PR for this?

[make-ing]

At the moment i don't have time for this, which would take me quite a while because i'm more of a backend guy.

After #173 I think somebody could pickup this issue

When using AWS CLI S3 Sync, or with the DataSync service (not applicable here), there are flags that mimic this exact behavior: --delete removes all files not in the locally pushed directory.

One alternative in this case would be a config item with a couple options. You can probably get ListObjects and diff it with your array of local files and delete everything not listed. Another option would be to just delete everything before uploading.

I might be able to submit a pull request soon. But no promises 😄

Hi @rlmestre, I would love to see this landed in a PR. If we could adopt it from the aws-cli and have a way to do this from our own source when aws-cli is not installed it would be great.
