Use PostCSS 6.0

[ai]

We released major update for PostCSS. It uses less memory and less dependencies, so it will be good to update dependency here.

Upgraded to PostCSS 6 ?

• postcss-modules-scope
• postcss-modules-values
• postcss-modules-extract-imports
• postcss-modules-local-by-default
• cssnano

I do it as soon as possible, the relevant postcss-modules-* got their PostCSS 6 update a few hours ago 😛

[ai]

Maybe we also need to wait cssnano release

[michael-ciniawsky]

Yep 😄

Can you try with v4.0.0-rc.0 and let me know how you get on? Going to allow a short period (2 weeks tops) before actually releasing to see if there's anything critical that needs fixing, but it's pretty much how I'd like it to be. I just need your feedback. 😄

@ben-eb I tried, everything works fine 👍 just wait stable release and update all to postcss v6

whats the situation ?

[michael-ciniawsky]

@EsrefDurna Still waiting for cssnano@latest

This would necessitate bumping the minimum supported node version to >=4.0.0, so the object-assign dependency can be dropped here, too.

[martinkadlec0]

It seems lots of popular libraries are doing just that lately anyway. Honestly, anyone still using <4 node version probably resigned on updating module dependencies long ago.

@wtgtybhertgeghgtwtg - For reference, the minimum supported NodeJS version is 4.3 which comes from Webpack v2, as v1 is no longer officially supported.

The above is usually done via webpack-defaults but in the case of css-loader, @sokra has re-written it completely as a part of his master plan regarding the stylesheets loader chain.

postcss in 6.0.8 had fixed reinstalled the support for Node.js 4.2.2

postcss/postcss#1052,

while as of today postcss v5 does not work with 4.2.2 Node.js version as of today due to the change in js-base-64 library

dankogai/js-base64#56

Looks like cssnano's postcss dependency has been updated to 6.0. Is anyone working on this?

[alexander-akait]

@seitensei wait when https://www.npmjs.com/package/cssnano release 4.0.0 stable version

Is there a timeline for this?
we are using [email protected] and [email protected] with webpack. On windows machine we run into the following issue :
Module build failed: ModuleBuildError: Module build failed: TypeError: WeakMap: incorrect

Note: post-css-loader version is 2.0.6. I mentioned the css-loader version in both in above comment.
