@wholebuzz/archive

Archive database using sorted chains of JSON array blocks. Each block is represented as a file (with random filename) on Cloud Storage and structured as an ArchiveBlock JSON object. Uses @wholebuzz/fs for atomic appends to Cloud Storage.

Example

const archive = new ArchiveDatabaseServer<Event>(
  'news',
  [
    {
      name: 'publisher',
      getter: getEventPublishers,
      sorter: compareEventReverse,
      blockDatabase: new FileStorageArchiveBlockDatabase<Event>(
        fileSystem,
        'gs://archive',
        parseEventJSON
      ),
      tipDatabase: new FileStorageArchiveTipDatabase(
        fileSystem,
        'gs://archive-index',
        sha1),
    },
  ])

await archive.addItems(item);
const tipBlock = await archive.getTipBlock(archive.indices[0], publisher)
