#UploadResizer

is an Express middleware that aims to make resizing and moving of image file uploads easier.

If you are looking for a general purpose upload solution try express-upload.

##Usage

You can use this middleware globally in your app your locally in your routes like this:

app.use(require("express-upload-resizer")({
    picture : {
        width: 100,
        height: 100,
        target: __dirname + "/public/images/pictures",
        method: "resizeAndCrop"
    },
    logo : {
        width: 100,
        height: 50,
        target: __dirname + "/public/images/logos",
        method: "resize"
    }
});

app.post("/thumbs", require("express-upload-resizer")({
    thumb : {
        width: 50,
        height: 50,
        target: __dirname + "/public/images/thumbs",
        method: "thumb"
    }
}));

You can specify more than one resize method per tyoe by using an array of options like this:

app.use(require("express-upload-resizer")({
    picture : [{
        width: 600,
        height: 400,
        target: __dirname + "/public/images/pictures",
        method: "resize"
    }, {
        width: 100,
        height: 100,
        target: __dirname + "/public/images/thumbs",
        method: "thumb"
    }]
});

##Options

• width and height: desired dimensions
• target: target directory
• method: can be resize (resize no cropping), resizeAndCrop (resize with cropping), thumb (more or less the same as resize and crop but faster)

##Nameing of files

The middleware tries to keep the original filename if it is unique to the location. Otherwise it will generate a unique name by appending a counter to the name. E.g. logo.png will become logo___1__.png_ if another logo.png already exists.

The path of the resized and moved file can be option with the file.path property, the name with file.name.

##Missing features:

• define an array of methods for each type to batch resize files
• supply additional arguments to graphics magic
