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,
})
