Installation

Redis is tested on the 2 last Go versions with support for modules. So make sure to initialize one first if you didn't do that yet:

go mod init github.com/<user>/<repo>

And then install the redis implementation:

go get github.com/gofiber/storage/redis

Examples

Import the storage package.

import "github.com/gofiber/storage/redis"

You can use the following possibilities to create a storage:

// Initialize default config
store := redis.New()

// Initialize custom config
store := redis.New(redis.Config{
	Host:      "127.0.0.1",
	Port:      6379,
	Username:  "",
	Password:  "",
	URL:       "",
	Database:  0,
	Reset:     false,
	TLSConfig: nil,
	PoolSize:  10 * runtime.GOMAXPROCS(0),
})

// or just the url with all information
store = redis.New(redis.Config{
    URL:     "redis://<user>:<pass>@127.0.0.1:6379/<db>",
    Reset:    false,
})

Config

type Config struct {
	// Host name where the DB is hosted
	//
	// Optional. Default is "127.0.0.1"
	Host string

	// Port where the DB is listening on
	//
	// Optional. Default is 6379
	Port int

	// Server username
	//
	// Optional. Default is ""
	Username string

	// Server password
	//
	// Optional. Default is ""
	Password string

	// Database to be selected after connecting to the server.
	//
	// Optional. Default is 0
	Database int

	// URL the standard format redis url to parse all other options. If this is set all other config options, Host, Port, Username, Password, Database have no effect.
	//
	// Example: redis://<user>:<pass>@localhost:6379/<db>
	// Optional. Default is ""
	URL string

	// Reset clears any existing keys in existing Collection
	//
	// Optional. Default is false
	Reset bool

	// TLS Config to use. When set TLS will be negotiated.
	//
	// Optional. Default is nil
	TLSConfig *tls.Config

	// Maximum number of socket connections.
	//
	// Optional. Default is 10 connections per every available CPU as reported by runtime.GOMAXPROCS.
	PoolSize int
}

Default Config

var ConfigDefault = Config{
	Host:      "127.0.0.1",
	Port:      6379,
	Username:  "",
	Password:  "",
	URL:       "",
	Database:  0,
	Reset:     false,
	TLSConfig: nil,
	PoolSize:  10 * runtime.GOMAXPROCS(0),
