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
}
}
};
