connect-static2x

Middleware for connect which works the same as static() except with support for dynamic retina and resized images based on the filename of a jpeg or png.

This makes it incredibly easy to server dynamically sized images and support retina devices without having to worry about creating sprites or multiple versions of images. Retina support is a snap when used with something like retina.js on the frontend.

static2x will interpret and process any jpeg or png in the following format using the default options:

• /[email protected] Nothing will happen. Original file will be returned instead of upscaling.
• /example-200x200.png The original file will be returned proportionally scaled to 200x200.
• /example-200x200c.png The original file will be returned proportionally scaled and cropped to 200x200.
• /[email protected] The original file will be returned proportionally scaled and cropped to 400x400.

Install

npm install connect-static2x

Options

This works exactly like static() except for a few extra options:

• maxSize Array; An array representing the max width and height of a possible resize. Set to false to not allow resizes. Default: [1000, 1000]
• allowCropping Boolean; Allow cropping for a requested image. Default: true
• allowRetina Boolean; Allow for retina requests (@2x). Note that if a image without a specific size is requested (e.g. [email protected]), the original image will be returned instead of upscaling.

Usage

express() // or connect()
  .use(require("connect-static2x")(__dirname + "/public", {
    maxSize: [1500, 1500]
  }))
  .listen(3000);
