Exercise: Capitalize RPC Unary API

Capitalize text RPC

Your goal is to implement a capitalize RPC Unary API in a TextEditorService.

• The function takes a Request message that has a single string.

• It returns a Result that represents the capitalized version of the input string.

Follow these steps:

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

2. Implement the server code: Implement the server logic to handle the request and return the capitalized response.

3. Test the server code by implementing the client: Ensure the client can send a string and the server responds with the capitalized string.

The client will send the string “hello world” and the server will respond with “HELLO WORLD”.

Good luck!

Step 1: Define the service in a .proto file

The RPC will be defined in a service inside a .proto file. The steps to create the file are listed below:

1. Create a .proto file named text-editor.proto.

2. The name of the service is TextEditorService. It contains an RPC named capitalize which takes a Request message and returns a Result message.

3. The Request message has a single string field named text.

4. The Result ...
