go-cache

Golang caching

This is a caching library heavily inspired by unkey-cache

It does not support all the features of unkey-cache yet.

• Encryption Middleware
• Tiered caching
• Memory Store
• Redis Store
• Libsql Store The following Table is needed:

CREATE TABLE cache
(
    key TEXT PRIMARY KEY,
    fresh_until INTEGER,
    stale_until INTEGER,
    value       TEXT
);

Todo:

• [] Cloudflare Store
• [] Cloudflare KV
• [] Metric Middleware

Extra Features:

• SwrMany
• GetMany
• SetMany
