How to use the glob-stream function in glob-stream

await new Promise((resolve, reject) =>
      globStream(
        [
          ...patterns.map(forceForwardSlashes),
          // Avoid reading asar files: electron patches in support for them, but
          // if we see an invalid one then it throws a synchronous error that
          // breaks glob. We don't care about asar's here, so just skip that:
          '!**/*.asar/**',
        ],
        {
          matchBase: true,
          cwd: base,
        },
      )
        .on('data', (value: globStream.Entry) =>
          todo.push(
            createMetadataForFile(fixDriveLetterAndSlashes(value.path))
              .then(parsed => parsed && onChild(parsed))

transform
              })

              this.push(snippet)
            })
          }

          callback()
        })
      }
    })

    return inStream.pipe(upperStream)
  }

  const files = gs(sourceDir, { ignore })

  return transformFiles(files)
}
