node-imageable: Image resizing middleware for Node.js

Wynn Netherland Wynn Netherland

Nifty image resizing middleware for Node.js that lets you manipulate remote images on the fly like so:

# resize an image with keeping ratio
http://localhost:3000/resize?url=http%3A%2F%2Fwww.google.com%2Fintl%2Fen_ALL%2Fimages%2Flogo.gif&size=200x200

# resize an image to given size without keeping the ratio
http://localhost:3000/fit?url=http%3A%2F%2Fwww.google.com%2Fintl%2Fen_ALL%2Fimages%2Flogo.gif&size=200x200

# crop a specific area of an image
http://localhost:3000/crop?url=http%3A%2F%2Fwww.google.com%2Fintl%2Fen_ALL%2Fimages%2Flogo.gif&crop=200x200%2B20%2B40

# crop a specific area and resize it with keeping the ratio
http://localhost:3000/crop?url=http%3A%2F%2Fwww.google.com%2Fintl%2Fen_ALL%2Fimages%2Flogo.gif&crop=200x200%2B20%2B40&size=100x50

# if secret is provided in config/config.json, all urls must have a hash following the resize method (see Hashing)
http://localhost:3000/fit/-hash-?url=http%3A%2F%2Fwww.google.com%2Fintl%2Fen_ALL%2Fimages%2Flogo.gif&size=200x200

# use the magic hash code that is valid for all requests, e.g. for testing
http://localhost:3000/fit/-magic-hash-?url=http%3A%2F%2Fwww.google.com%2Fintl%2Fen_ALL%2Fimages%2Flogo.gif&size=200x200

# append any fancy name for nice looking urls and image downloads
http://localhost:3000/fit/-hash-/Fancy-Ignored-Name.gif?url=http%3A%2F%2Fwww.google.com%2Fintl%2Fen_ALL%2Fimages%2Flogo.gif&size=200x200

The middleware ships with some basic logging and request tracking which you can extend with callbacks in your app. Check out the README or sample app for more.
