grpc-server-js

Pure JavaScript gRPC Server

Documentation

The goal is to be largely compatible with the existing Server implementation.

Features

• Unary calls.
• Streaming client request calls.
• Streaming server response calls.
• Bidirectional streaming calls.
• Deadline and cancellation support.
• Support for gzip and deflate compression, as well as uncompressed messages.
• Server credentials for handling both secure and insecure calls.
• gRPC Metadata.
• gRPC logging.
• No production dependencies.
• No C++ dependencies. This implementation relies on Node's http2 module.
• Supports the following gRPC server options:
  • grpc.http2.max_frame_size
  • grpc.keepalive_time_ms
  • grpc.keepalive_timeout_ms
  • grpc.max_concurrent_streams
  • grpc.max_receive_message_length
  • grpc.max_send_message_length
  • All possible options and their descriptions are available here.
• Supports the following gRPC environment variables:
  • GRPC_DEFAULT_SSL_ROOTS_FILE_PATH
  • GRPC_SSL_CIPHER_SUITES
  • GRPC_VERBOSITY
  • All possible environment variables and their descriptions are available here.

Public API Deviations from the Existing grpc.Server

• Server.prototype.bind() is an async function.
• The deprecated Server.prototype.addProtoService() is not implemented.
• Server.prototype.addHttp2Port() is not implemented.
