### Installation
|
|
Postgres is tested on the 2 last [Go versions](https://golang.org/dl/) with support for modules. So make sure to initialize one first if you didn't do that yet:
|
|
```bash
|
|
go mod init github.com/<user>/<repo>
|
|
```
|
|
And then install the postgres implementation:
|
|
```bash
|
|
go get github.com/gofiber/storage/postgres
|
|
```
|
|
|
|
### Examples
|
|
Import the storage package.
|
|
```go
|
|
import "github.com/gofiber/storage/postgres"
|
|
```
|
|
|
|
You can use the following possibilities to create a storage:
|
|
```go
|
|
// Initialize default config
|
|
store := postgres.New()
|
|
|
|
// Initialize custom config
|
|
store := postgres.New(postgres.Config{
|
|
Host: "127.0.0.1",
|
|
Port: 5432,
|
|
Database: "fiber",
|
|
Table: "fiber_storage",
|
|
Reset: false,
|
|
GCInterval: 10 * time.Second,
|
|
SslMode: "disable",
|
|
})
|
|
|
|
// Initialize custom config using connection string
|
|
store := postgres.New(postgres.Config{
|
|
ConnectionURI: "postgresql://user:password@localhost:5432/fiber"
|
|
Reset: false,
|
|
GCInterval: 10 * time.Second,
|
|
})
|
|
```
|
|
|
|
