Installation

SQLite3 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 sqlite3 implementation:

go get github.com/gofiber/storage/sqlite3

Examples

Import the storage package.

import "github.com/gofiber/storage/sqlite3"

You can use the following possibilities to create a storage:

// Initialize default config
store := sqlite3.New()

// Initialize custom config
store := sqlite3.New(sqlite3.Config{
Database: "./fiber.sqlite3",
Table: "fiber_storage",
Reset: false,
GCInterval: 10 * time.Second,
MaxOpenConns: 100,
MaxIdleConns: 100,
ConnMaxLifetime: 1 * time.Second,
})

Config

type Config struct {
// Database name
//
// Optional. Default is "fiber"
Database string

// 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

// //////////////////////////////////
// Adaptor related config options //
// //////////////////////////////////

// MaxIdleConns sets the maximum number of connections in the idle connection pool.
//
// Optional. Default is 100.
MaxIdleConns int

// MaxOpenConns sets the maximum number of open connections to the database.
//
// Optional. Default is 100.
MaxOpenConns int

// ConnMaxLifetime sets the maximum amount of time a connection may be reused.
//
// Optional. Default is 1 second.
ConnMaxLifetime time.Duration
}

Default Config

var ConfigDefault = Config{
Database: "./fiber.sqlite3",
Table: "fiber_storage",
Reset: false,
GCInterval: 10 * time.Second,
MaxOpenConns: 100,
MaxIdleConns: 100,
ConnMaxLifetime: 1 * time.Second,
