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,
    imageVersions: {
        width:  80,
        height: 80
    },
    accessControl: {
        allowOrigin: '*',
        allowMethods: 'OPTIONS, HEAD, GET, POST, PUT, DELETE',
        allowHeaders: 'Content-Type, Content-Range, Content-Disposition'
    },
    storage : {
        type : 'aws',
        aws : {
            accessKeyId :  'xxxxxxxxxxxxxxxxx',
            secretAccessKey : 'xxxxxxxxxxxxxxxxx',
            region : 'us-east-1',//make sure you know the region, else leave this option out
            bucketName : 'xxxxxxxxxxxxxxxxx'
        }
    }
};

// init the uploader
var uploader = require('blueimp-file-upload-expressjs')(options);


module.exports = function (router) {
    router.get('/upload', function(req, res) {
      uploader.get(req, res, function (obj) {
            res.send(JSON.stringify(obj)); 
      });
      
    });

    router.post('/upload', function(req, res) {
      uploader.post(req, res, function (obj) {
            res.send(JSON.stringify(obj)); 
      });
      
    });
    
    // the path SHOULD match options.uploadUrl
    router.delete('/uploaded/files/:name', function(req, res) {
      uploader.delete(req, res, function (obj) {
            res.send(JSON.stringify(obj)); 
      });
      
    });
    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('blueimp-file-upload-expressjs')(options);

app.get('/upload', function(req, res) {
    uploader.get(req, res, function (obj) {
    res.send(JSON.stringify(obj)); 
})
    .post('/upload', // ...
    .delete('/uploaded/files/:name', // ...

// 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);
