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:

`bash
$ 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 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.

`js
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
`
