Installation

Postgres 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 postgres implementation:

go get github.com/gofiber/storage/postgres/v3

Examples

Import the storage package.

import "github.com/gofiber/storage/postgres/v3"

You can use the following possibilities to create a storage:

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

// Initialize custom config
store := postgres.New(postgres.Config{
	DB:              dbPool,
	Table:           "fiber_storage",
	Reset:           false,
	GCInterval:      10 * time.Second,
})

type Config struct {
	// DB pgxpool.Pool object will override connection uri and other connection fields
