Github GraphQL - Get all file contents in repository

get-all-files.gql

# Provide $query as a variable. 
# The query is the same as you would enter into the search field e.g. "org:johndevs in:name feedreader"

query GetFilesQuery($branch: GitObjectID, $query: String!) {
 search(first: 1, type: REPOSITORY, query: $query) {
    edges {
      node {
        ... on Repository {
          object(expression: "master:", oid: $branch) {
            ... on Tree {
              entries {
                name
                object {
                  ... on Blob {
                    text
                  }
                }
              }
            }
          }
        }
      }
    }
  }
}

Don't use master: but HEAD:

Not every repo has master: as the default branch

How would one grab the updated date or committedDate for each of these TreeEntries?

I tried using Commit instead of Blob and that didn't work. Got all empty objects. {}

              object {
                  ... on Commit {
                    committedDate
                    authoredDate
                  }
                }

I couldn't figure it out either. Put a stackoverflow question on it:
