imgop

Image-optimisation server powered by libvips

/example.jpg?w=1050&h=700

Requirements

• libvips
• iojs

How it works

• Retrieve images from an s3 bucket
• Cache downloaded images to the file system for subsequent renders using fs-lru-cache
• Resize and adjust image quality using parameters added to the querystring
• Use behind a CDN to cache resized images

Usage

Set the following environment variables:

AWS_ACCESS_KEY_ID
AWS_SECRET_ACCESS_KEY
IMGOP_BUCKET // bucket to retrieve images from

Install imgop and run it on your server:

$ npm install -g imgop
$ imgop

The available options are:

Usage: imgop [options]

Options:

  -h, --help         output usage information
  -V, --version      output the version number
  -p, --port <port>  Port to listen on [$PORT or 3000]

Alternatively, you can also require imgop as a module which returns a Function that creates a http.Server instance.

require('imgop')()
.listen(3000);

Modify an image by adding parameters to the querystring:

http://localhost:3000/example.jpg?w=1050&h=700&q=75&fit=crop&fm=png
