The gRPC library is one of the standard library modules of the Ballerina language.

This provides support for the gRPC messaging protocol. gRPC is an inter-process communication technology that allows you to connect, invoke, and operate distributed, heterogeneous applications as easily as making a local function call. The gRPC protocol is layered over HTTP/2 and uses Protocol Buffers for marshaling/unmarshaling messages. This makes gRPC highly efficient on wire and a simple service definition framework.

This Library supports the messaging patterns below. For more information on the supported operations, go to the grpc module.

• Simple RPC (Unary RPC)
• Server streaming RPC
• Client streaming RPC
• Bidirectional Streaming RPC

For example demonstrations of the usage, go to Ballerina By Examples.
