This meteor package compiles your .less files into CSS, adds vendor prefixes to CSS rules and includes the results in the client CSS bundle.

Story I was not able to compile Semantic UI with the package lauricio:less-autoprefixer so I decided to start from fresh.

meteor add flemay:less-autoprefixer

You can pass custom options to autoprefixer by setting AUTOPREFIXER_OPTIONS environment variable: export AUTOPREFIXER_OPTIONS='{ "browsers": ["Chrome 36", "iOS 7"]}'

To unset environment variable run: unset AUTOPREFIXER_OPTIONS

If no AUTOPREFIXER_OPTIONS environment variable is found it fallbacks to autoprefixer default options: ["> 1%", "last 2 versions", "Firefox ESR", "Opera 12.1"]

For more info on autoprefixer options please check https://github.com/ai/browserslist#queries

This package uses the following npm modules:

• less@2.4.0
• less-plugin-autoprefix@1.4.2

1. $ meteor create test-less-autoprefixer
2. $ mkdir test-less-autoprefixer/packages
3. $ cd test-less-autoprefixer/packages
4. $ git clone https://github.com/flemay/less-autoprefixer.git
5. $ meteor test-packages flemay:less-autoprefixer

This package is based on the less package from Meteor. However it does not cut down less npm module and it uses the function less.render instead of the combination of less.Parser and toCSS as suggested by less usage documentation.

It is also based on lauricio:less-autoprefixer. I wasn't able to use it to compile semantic-ui and after debugging and debugging I decided to start from fresh and created this package.

• test uses my package to test
• same structure as less package
  • Use of Fiber/Future
  • Exception handling
