Getting started

Install aws-sdk using npm

$ npm install aws-sdk

Create a json file name config.json in the project root directory

{
    "accessKeyId": "<aws-access-key>", 
    "secretAccessKey": "<aws-secret-key>", 
    "region": "ap-northeast-1"
}

Usage

Import the aws-sdk

const AWS = require('aws-sdk')

Initialize S3 object for doing the operations

// load aws s3 configuration from json file
AWS.config.loadFromPath(path.join(__dirname, '<relative-path-to-config.json>'))

// initialize S3 object for doing operations
var S3 = new AWS.S3({
   apiVersion: '2006-03-01'
})

Get image from S3

// setup the params for get object operation
var params = {
  Bucket: <path-to-where-the-target-object-is-stored>
  Key: <object-name-in-s3>
}

// Async function to get object from S3 using aws-sdk
S3.getObject(params, function (err, data) {
  if (err) throw err
  console.log(data)
})
.catch(err => console.log(err))

Upload Image to S3

// setup the params for get object operation
var params = {
  Bucket: "bucket name with path",
  Key: "<filename>",
  Body: "<image stream>"
}

// Async function to get object from S3 using aws-sdk
S3.getObject(params, function (err, data) {
  if (err) throw err
  console.log(data)
})
.catch(err => console.log(err))
