Exercise: Encode Bi-Directional Streaming API

Encode text RPC

In this exercise, your goal is to implement an encode bi-directional streaming API in a TextEditorService.

• The function takes a stream of Request messages where each message contains a string.

• It returns a stream of Result messages where each message represents an encoded version of the input string.

Follow these steps:

1. Define the RPC in a .proto file: Define the RPC in the service definition in the proto file.

2. Implement the server code: Implement the server logic to handle the bi-directional streaming requests and return the encoded responses.

3. Test the server code by implementing the client: Ensure the client can send multiple strings and receive the encoded strings back.

Example:

The client will send a stream of strings (“hello”, “world”, “from”, “gRPC!”) and the server will respond with a stream of encoded strings (“ifmmp”, “xpsme”, “gspn”, “hSQD"”).

Good luck!

Step 1: Define the RPC in the .proto file

Add the encode RPC to the TextEditorService in the text-editor.proto file. ...
