Go-Redis

Go-Redis is a simplified Redis-like in-memory database server implemented in Go, supporting a subset of the Redis protocol. This project also includes a client that communicates with the server using the Redis Serialization Protocol (RESP).

Features

In-memory key-value storage
Support for commands: SET, GET, DEL, EXPIRE, KEYS, TTL, ZADD, ZRANGE
RESP protocol for client-server communication
Configurable server settings

Prerequisites

Go (version 1.14 or later)

Installation

Clone the repository:

git clone https://github.com/yourusername/go-redis.git
cd basic-go-redis

Build the server and client:

go build -o bin/server ./cmd/server
go build -o bin/client ./cmd/client

You could also do the following:

To run the server:

go run cmd/server/main.go

To run the client:

go run cmd/client/main.go

Configuration

Edit config.json to specify the server port and logging level:

{
    "server_port": "6379",
    "log_level": "info"
}

If config.json is not present, the server defaults to port 6379 and log level info.

Running the Server

Navigate to the bin directory and run:

./server

Running the Client

In a separate terminal window, navigate to the bin directory and run:

./client

Usage

With the client running, you can enter Redis commands, such as(note that it supports only completely uppercase commands):

go-redis-cli> SET keys Abhilasha
OK
go-redis-cli> GET keys
Abhilasha
go-redis-cli> SET key Abhilasha
OK
go-redis-cli> KEYS *
1) "key"
2) "keys"

go-redis-cli> DEL keys
1
go-redis-cli> TTL keys
-1
go-redis-cli> EXPIRE keys 80
1
go-redis-cli> ZADD Myset 1 GulabJamun
1
go-redis-cli> ZRANGE Myset 0 1
[GulabJamun]

Type exit to quit the client.

Testing

Development

The server's execution logic is located in cmd/server/main.go.
The in-memory store logic for the server is in internal/store/store.go.
The creation and request handling for the server is in internal/server/server.go.
Client implementation can be found in cmd/client/main.go.
RESP protocol handling is in internal/protocol/resp.go.
Configuration handling is managed in pkg/config/config.go.
Logging utilities are located in pkg/logger/logger.go.
