multer-s3-imager

2.0.9 • Public • Published

Imager multer storage engine permit to resize, auto-orient and upload an image to AWS S3.

This project is mostly an integration piece for existing code samples from Multer's storage engine documentation. And was inspired from multer-s3 and gm

Requirements

Debian/Ubuntu

apt-get install graphicsmagick

MacOS X

brew install graphicsmagick

Install

npm install multer-imager --save

Tests

Tested with s3rver instead of your actual s3 credentials. Doesn't require a real account or changing of hosts files. Includes integration tests ensuring that it should work with express + multer.

npm test

Usage

var express = require('express');
var app = express();
var multer = require('multer');
var imager = require('multer-imager');

var upload = multer({
  storage: imager({
    dirname: 'avatars',
    bucket: 'bucket-name',
    accessKeyId: 'aws-key-id',
    secretAccessKey: 'aws-key',
    region: 'us-east-1',
    filename: function (req, file, cb) {  // [Optional]: define filename (default: random)
      cb(null, Date.now())                // i.e. with a timestamp
    },                                    //
    gm: {                                 // [Optional]: define graphicsmagick options
      width: 200,                         // doc: http://aheckmann.github.io/gm/docs.html#resize
      height: 200,
      options: '!',
      format: 'png'                       // Default: jpg
    },
    s3 : {                                // [Optional]: define s3 options
      Metadata: {                         // http://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectPUT.html
        'customkey': 'data'               // "x-amz-meta-customkey","value":"data"
      }
    }
  })
});

// Cf.: https://github.com/expressjs/multer/blob/master/README.md
app.post('/upload', upload.array('file', 1), function(req, res, next){ 
  console.log(req.files); // Print upload details
  res.send('Successfully uploaded!');
});
