README

gache

gache is thinnest cache library for go application

Requirement

Go 1.9

Installation

go get github.com/kpango/gache

Example

	// data sets
	var (
		key1 = "key"
		key2 = 5050
		key3 = struct{}{}

		value1 = "value"
		value2 = 88888
		value3 = struct{}{}
	)

	// store cache default expire is 30 Seconds
	gache.Set(key1, value3)
	gache.Set(key2, value2)
	gache.Set(key3, value1)

	// load cache data
	v1, ok := gache.Get(key1)

	v2, ok := gache.Get(key2)

	v3, ok := gache.Get(key3)
