### Installation
ArangoDB is tested on the 2 last (1.14/1.15) [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 mysql implementation:
```bash
go get github.com/gofiber/storage/arangodb
```

### Examples
Import the storage package.
```go
import "github.com/gofiber/storage/arangodb"
```

You can use the following possibilities to create a storage:
```go
// Initialize default config
store := arangodb.New()

// Initialize custom config
store := arangodb.New(arangodb.Config{
	Host:       "http://127.0.0.1",
	Port:       8529,
	Database:   "fiber",
	Collection: "fiber_storage",
	Reset:      false,
	GCInterval: 10 * time.Second,
})
```

### Config
```go
type Config struct {
	// Host name where the DB is hosted
	//
	// Optional. Default is "http://127.0.0.1"
	Host string

	// Port where the DB is listening on
	//
	// Optional. Default is 8529

}
```
