Middleware that prefixes css on-the-fly. Intended to be used in a
development setting with the
express.static middleware, but should
work with any middleware further down the stack, even an http proxy.
The response will be rewritten under these circumstances:
- If the response is served with a
autoprefixer plays nice with conditional GET. If the original response
has an ETag, autoprefixer will add to it so the ETag of the compiled
response never clashes with the original ETag. That prevents the
middleware issuing the original response from being confused into
sending a false positive
304 Not Modified if autoprefixer is turned
off or removed from the stack later.
Important note regarding node 0.10
Major versions of autoprefixer higher than 5 will not support node 0.10, as they rely on features not supported in that version. If you are still using node 0.10 you should stick to autoprefixer in the 5-series, and use express-autoprefixer from the major version 4 range.
Major version 5 and later of express-autoprefixer will use autoprefixer version 6, and will hence no longer support node 0.10.
Make sure you have node.js and npm installed, then run:
npm install express-autoprefixer
var express =autoprefixer =root = '/path/to/my/static/files';express;
