# simples3 : Simple no frills AWS S3 Library using REST with V4 Signing

## Overview [![GoDoc](https://godoc.org/github.com/rhnvrm/simples3?status.svg)](https://godoc.org/github.com/rhnvrm/simples3) [![Go Report Card](https://goreportcard.com/badge/github.com/rhnvrm/simples3)](https://goreportcard.com/report/github.com/rhnvrm/simples3) [![GoCover](https://gocover.io/_badge/github.com/rhnvrm/simples3)](https://gocover.io/_badge/github.com/rhnvrm/simples3) [![Zerodha Tech](https://zerodha.tech/static/images/github-badge.svg)](https://zerodha.tech) 

SimpleS3 is a Go library for manipulating objects 

in S3 buckets using REST API calls or Presigned URLs signed 

using AWS Signature Version 4.

## Install

```sh

go get github.com/rhnvrm/simples3

```

## Example

```go

testTxt, _ := os.Open("testdata/test.txt")

defer testTxt.Close()

// Create an instance of the package

// You can either create by manually supplying credentials

// (preferably using Environment vars)

s3 := simples3.New(Region, AWSAccessKey, AWSSecretKey)

// or you can use this on an EC2 instance to 

// obtain credentials from IAM attached to the instance.

s3, _ := simples3.NewUsingIAM(Region)

// You can also set a custom endpoint to a compatible s3 instance. 

s3.SetEndpoint(CustomEndpoint)

// Note: Consider adding a testTxt.Seek(0, 0)

// in case you have read 

// the body, as the pointer is shared by the library.

// File Upload is as simple as providing the following

// details.

resp, err := s3.FileUpload(simples3.UploadInput{

    Bucket:      AWSBucket,

    ObjectKey:   "test.txt",

    ContentType: "text/plain",

    FileName:    "test.txt",

    Body:        testTxt,

})

// Similarly, Files can be deleted.

err := s3.FileDelete(simples3.DeleteInput{

    Bucket:    os.Getenv("AWS_S3_BUCKET"),

    ObjectKey: "test.txt",

})

// You can also download the file.

file, _ := s3.FileDownload(simples3.DownloadInput{

    Bucket:    AWSBucket,

    ObjectKey: "test.txt",

})

data, _ := ioutil.ReadAll(file)

file.Close()

// You can also use this library to generate

// Presigned URLs that can for eg. be used to

// GET/PUT files on S3 through the browser.

var time, _ = time.Parse(time.RFC1123, "Fri, 24 May 2013 00:00:00 GMT")

url := s.GeneratePresignedURL(PresignedInput{

    Bucket:        AWSBucket,

    ObjectKey:     "test.txt",

    Method:        "GET",

    Timestamp:     time,

    ExpirySeconds: 86400,

})

```
