Building a Redis Client in C++ (Part 4) | Sending Commands to Redis (RESP Protocol)
In Part 4 of our Redis CLI project, we implement the core functionality for sending commands to the Redis server using the RESP (Redis Serialization Protocol). We introduce CommandHandler::buildRESPcommand() to properly format commands, and RedisClient::sendCommand() to send them over the established connection. Finally, we integrate both functions into the CLI loop to enable real Redis command execution.
🔹 Topics Covered:
✅ Implemented CommandHandler::buildRESPcommand() for RESP formatting
✅ Created RedisClient::sendCommand() to transmit commands to Redis
✅ Integrated both functions into the CLI loop
✅ Successfully sent commands to Redis!
