Installation

GORM 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 gorm implementation:

go get github.com/gandaldf/fiber-storage/gorm

Examples

Import the storage package.

import "github.com/gandaldf/fiber-storage/gorm"

You can use the following possibilities to create a storage:

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

// Initialize custom config using dialect and connection strings
store := gorm.New(gorm.Config{
	Dialect:       "postgres", // or mysql / sqlite / sqlserver
	ConnectionURI: "postgresql://user:password@localhost:5432/fiber",
	PrepareStmt:   true,
	Table:         "gorm_sessions",
	Reset:         false,
	GCInterval:    10 * time.Second,
})

// Initialize custom config using database connection
store := gorm.New(gorm.Config{
	Db: 			db,
	Table:         	"gorm_sessions",
	Reset:          false,
	GCInterval:     10 * time.Second,
})

Config

// Config defines the config for storage.
type Config struct {
	// DB will override Dialect and ConnectionURI values if used
	//
	// Optional. Default is nil
	Db *gorm.DB

	// Dialect string to use for DB. Will override all other authentication values if used
	//
	// Optional. Default is ""
	Dialect string

	// ConnectionURI string to use for DB. Will override all other authentication values if used
	//
	// Optional. Default is ""
	ConnectionURI string

	// SkipDefaultTransaction executes write operations outside of transactions for better performances
	//
	// Optional. Default is false
	SkipDefaultTransaction bool

	// PrepareStmt prepares statement when executing any SQL and caches them to speed up future calls
	//
	// Optional. Default is false
	PrepareStmt bool

	// Table name
	//
	// Optional. Default is "fiber_storage"
	Table string

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

	// Time before deleting expired keys
	//
	// Optional. Default is 10 * time.Second
	GCInterval time.Duration
}

Default Config

var ConfigDefault = Config{
	Db:                     nil,
	Dialect:                "",
	ConnectionURI:          "",
	SkipDefaultTransaction: false,
	PrepareStmt:            false,
	Table:                  "fiber_storage",
	Reset:                  false,
	GCInterval:             10 * time.Second,
	maxOpenConns:           100,
	maxIdleConns:           100,
	connMaxLifetime:        1 * time.Second,
}
