LiteRedis

A lightweight, embeddable Redis-style key-value store written in C++.
No daemon, no configuration, no external dependencies — just drop it into your app and go.

---

🚀 Why LiteRedis?

LiteRedis is designed for developers who love Redis-style data access but don’t want to spin up a server for every project. Whether you're building a CLI tool, an offline desktop app, or prototyping fast logic, LiteRedis gives you:

• In-memory storage with Redis-like semantics
• TTL (time-to-live) support for expiring keys
• Optional snapshot-based persistence
• Simple C++ API or command-line interface
• Zero configuration, embeddable as a library

---

🧠 Use Cases

• Terminal-based productivity apps (CRM, note trackers, offline task managers)
• Local development tools needing fast state/caching
• Embedded systems where Redis is overkill
• Educational tools for learning database internals

🛠️ Example Usage

C++ (Library)

#include "lite_redis.h"

RedisLight db;
db.set("foo", "bar");
std::string value = db.get("foo");  // "bar"
db.expire("foo", 10);               // Expires in 10 seconds
db.save("snapshot.rdb");

CLI

$ ./literedis-cli SET foo bar
OK
$ ./literedis-cli GET foo
bar
$ ./literedis-cli EXPIRE foo 60
OK
