buildServerDependencies function

ServerDependencies buildServerDependencies(ServerConfig config, { String schemaJson = '{}', })

Builds the ServerDependencies graph from config: the file store (local or S3), a file-backed job store, the pipeline render runner + queue, retention, and the download-token signer.

This is the composition root the server entrypoint calls. Job records live on the local disk (under the storage dir) so they survive a restart even with an S3 file backend; schemaJson is the VideoSpec schema to serve.

Implementation

ServerDependencies buildServerDependencies(ServerConfig config, {String schemaJson = '{}'}) {
  final fileStore = config.storageBackend == StorageBackend.s3
      ? _s3FileStore(config.s3!)
      : LocalFileStore(Directory(config.localStorageDir));
  final jobStore = FileJobStore(Directory('${config.localStorageDir}/.jobs'));
  final queue = RenderQueue(
    runner: PipelineRenderRunner(
      renderProject: config.renderProject,
      ffmpegPath: config.ffmpegPath,
      aiEnv: config.aiEnv,
    ),
    jobStore: jobStore,
    fileStore: fileStore,
    fileTtl: config.fileTtl,
    concurrency: config.renderConcurrency,
  );
  return ServerDependencies(
    config: config,
    queue: queue,
    jobStore: jobStore,
    fileStore: fileStore,
    retention: DefaultRetentionService(jobStore, fileStore),
    signer: DownloadTokenSigner(config.downloadSigningKey),
    schemaJson: schemaJson,
  );
