Caching

A base class package for caching.

Constructing

You can construct the cache like so:

// main.go
package main

import (
    // ...
    "github.com/vigilantapps/viper-common/cache"
)

func main() {
    //...

    // connecting to a cache:
    // if envvar DISABLE_CACHE=1, then a null cache is returned
    // otherwise the predicate argument is called and your new cache
    // is returned
	c := cache.Bootstrap(func() (cache.Abstraction, error) {
        return cache.Redis(os.Getenv("CACHE_ADDR"), 0, expirationWindow)
    })
    
    // ...
}

Usage / Examples

The recommendation is that you build a higher-order component which wraps this cache instead of exposing it directly. Keys should be sensible and unique, JSON for serialising values; examples of which can be found here:
