xpress-upload

A simple express module for integrating the jQuery File Upload frontend plugin. Inspired by blueimp-file-upload-expressjs

Main features

1. Using lwip to proccess image files

Support creating thumbnails for jpg, gif, png images automatically.

1. NodeJs friendly callback API

2. Lightweight

Only support uploading files to your local web applications. If you wanna upload files to AWS, you should use blueimp-file-upload-expressjs instead!

Installation

Setup an Express project and install the package.

$ npm install xpress-upload

Tests

Unit tests can be run with Jasmine using npm test or this command:

$ jasmine-node specs/

Manual end to end tests can be done with this full project. Change the require() path of uploadManager.js to link it this cloned repository.

Usage with options

(refer tutorial)

// config the uploader
var options = {
    tmpDir:  __dirname + '/../public/uploaded/tmp',
    uploadDir: __dirname + '/../public/uploaded/files',
    uploadUrl:  '/uploaded/files/',
    maxPostSize: 11000000000, // 11 GB
    minFileSize:  1,
    maxFileSize:  10000000000, // 10 GB
    acceptFileTypes:  /.+/i,
    // Files not matched by this regular expression force a download dialog,
    // to prevent executing any scripts in the context of the service domain:
    inlineFileTypes:  /\.(gif|jpe?g|png)/i,
    imageTypes:  /\.(gif|jpe?g|png)/i,
    copyImgAsThumb : true, // required
    imageVersions :{
        maxWidth : 200,
        maxHeight : 200
    },
    accessControl: {
        allowOrigin: '*',
        allowMethods: 'OPTIONS, HEAD, GET, POST, PUT, DELETE',
        allowHeaders: 'Content-Type, Content-Range, Content-Disposition'
    }
};
 
// init the uploader in your controller
var uploader = require('xpress-upload')(options);
 
 
module.exports = function (router) {
    router.get('/upload', function(req, res) {
      uploader.get(req, res, function (err,obj) {
            if(!err){
                res.json( obj );
            }
      });
      
    });
 
    router.post('/upload', function(req, res) {
      uploader.post(req, res, function (error,obj, redirect) {
          if(!error)
          {
            res.json( obj ); 
          }
      });
      
    });
    
    // the path SHOULD match options.uploadUrl
    router.delete('/uploaded/files/:id', function(req, res) {
      uploader.delete(req, res, function (err,obj) {
            res.json({error:err}); 
      });
      
    });
    return router;
}

SSL Support

Set the useSSL option to true to use the package with an HTTPS server.

var express = require('express')
var fs = require('fs')
var https = require('https');
 
var app = express()
 
// config the uploader
var options = {
    ...
    useSSL: true
    ...
};
 
// init the uploader
var uploader = require('xpress-upload')(options);
 
app.get('/upload', function(req, res) {
    uploader.get(req, res, function (err,obj) {
    if(!err)
        res.json( obj ); 
})
    .post('/upload', // ...
    .delete('/uploaded/files/:id', // ...
 
// create the HTTPS server
var app_key = fs.readFileSync('key.pem');
var app_cert = fs.readFileSync('cert.pem');
 
https.createServer({key: app_key, cert: app_cert}, app).listen(443);
 

Multiple thumbnails

To generate multiple thumbnails while uploading

var options = {
  tmpDir: __dirname + '/../public/uploaded/tmp',
  uploadDir: __dirname + '/../public/uploaded/files',
  uploadUrl: '/uploaded/files/',
  copyImgAsThumb: true, // required
  imageVersions: {
    maxWidth: 200,
    maxHeight: 200
  }
};

copyImgAsThumb needs to be set to true. imageVersions, maxWidth and maxHeight will by default create a thumbnail folder and place the specified width/height thumbnail in it.

Optionally, you can omit the maxHeight. In this case, it will be resize proportionally to the specified width.

imageVersions: {
    maxWidth: 200
  },

also

imageVersions: {
    maxWidth: 200,
    maxHeight : 'auto'
  },

PS : auto value works only with height.

You can also specify multiple thumbnail generations like

var options = {
  tmpDir: __dirname + '/../public/uploaded/tmp',
  uploadDir: __dirname + '/../public/uploaded/files',
  uploadUrl: '/uploaded/files/',
  copyImgAsThumb: true,
  imageVersions: {
    maxWidth: 200,
    maxHeight: 'auto',
    "large" : {
        width : 600,
        height : 600
    },
    "medium" : {
        width : 300,
        height : 300
    },
    "small" : {
        width : 150,
        height : 150
    }
  }
};
