This project is the source of a web app that allows us to view and edit Google Cloud Storage files. First, we sign-in to provide access to GCS. Next, we select the bucket we wish to look for files. Finally, we select the files we wish to edit, view their content and optionally write any changes back.
GCS is immutable blob storage which means that when we save changes, we are writing back the whole file replacing what was previously present.
This project is as-is and not a Google product or offering. It is open source and there is no formal support.
