Deprecation of Autoprefixer's process() method

[buschtoens]

Since very recently installing ember-cli-autoprefixer results in this deprecation warning during a build:

Autoprefixer's process() method is deprecated and will removed in next major release. Use postcss([autoprefixer]).process() instead

It appears like they've changed the whole build pipeline and Autoprefixer is now a plugin of PostCSS.

There is a broccoli plugin for PostCSS: https://github.com/jeffjewiss/broccoli-postcss

Yea, take a look at https://github.com/jeffjewiss/ember-cli-postcss

I couldn't find a simple way to get ember-cli-postcss and ember-cli-less to work together. ember-cli-autoprefixer works fine with ember-cli-less so for the time being I'll keep using it even the warning is a little annoying.

Thanks for reporting this, and sorry that I haven't been more responsive. broccoli-autoprefixer was just updated to use postcss, so I released a new version now that depends on this new version. This should make the annoying warning go away :)

Thanks to @salzhrani for reporting it over there: sindresorhus/broccoli-autoprefixer#9

Regarding ember-cli-postcss: I think that is a great thing to have, but I also think there is value in having a dedicated addon just for autoprefixer alone to make it super simple to set that up if that's all you need. That is the case for a lot of people.

Woot!!!
