How to use

Caching result of a query

const client = knex(config);

const result = await client("users").cache();
// returns query result and caches if not set
// calling this again will return the cached result

const result = await client("users")
  .select("name", "email")
  .where("user_id", "123")
  .cache();
// can be chained on to any knex query

const result = await client("users").cache({ key: "fetchUsers" });
// use a custom cache key

Invalidating cache

const client = knex(config);

client("users").invalidate();
// invalidate query automatically

client.invalidate({ key: "fetchUsers" });
// invalidate a cache using a key

Clearing cache

const client = knex(config);

client.clearCache();
// clear all records in the cache
