Installation

S3 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 s3 implementation:

go get github.com/gofiber/storage/s3

Examples

Import the storage package.

import "github.com/gofiber/storage/s3"

You can use the following possibilities to create a storage:

// Initialize default config
store := s3.New()

// Initialize custom config
store := s3.New(s3.Config{
Bucket: "my-bucket-url",
Endpoint: "my-endpoint",
Region: "my-region",
Reset: false,
})

Config

// Config defines the config for storage.
type Config struct {
// S3 bucket name
Bucket string

// AWS endpoint
Endpoint string

// AWS region
Region string

// Request timeout
//
// Optional. Default is 0 (no timeout)
RequestTimeout time.Duration

// Reset clears any existing keys in existing Bucket
//
// Optional. Default is false
Reset bool

// Credentials overrides AWS access key and AWS secret access key. Not recommended.
//
// Optional. Default is Credentials{}
Credentials Credentials

// The maximum number of times requests that encounter retryable failures should be attempted.
//
// Optional. Default is 3
MaxAttempts int

}

type Credentials struct {
AccessKey string
SecretAccessKey string
}

Default Config

The default configuration lacks Bucket, Region, and Endpoint which are all required and must be overwritten:

// ConfigDefault is the default config
var ConfigDefault = Config{
Bucket: "",
Region: "",
Endpoint: "",
Credentials: Credentials{},
MaxAttempts: 3,
RequestTimeout: 0,
Reset: false,
}
