place-content/items issue

[nevolgograd]

I have simple webpack/postcss stack and my build is failing each time I use place-content or place-items properties

Here’s the error:

Module build failed (from ./node_modules/postcss-loader/dist/cjs.js):
TypeError: Cannot read properties of undefined (reading 'includes')

I'm using latest version of the package:

"postcss-preset-env": "^7.0.1",

PostCSS config:

module.exports = {
  plugins: [
    require('postcss-import'),
    require('postcss-normalize'),
    require('postcss-color-mod-function'),
    require('postcss-preset-env')
  ]
};

Webpack config:

{
  test: /\.(scss|css)$/,
  use: [
    {
      loader: 'css-loader',
      options: {
        modules: true,
        importLoaders: 1
      }
    },
    {
      loader: 'postcss-loader'
    },
    {
      loader: 'sass-loader'
    }
  ]
}

I will be grateful for any advice!

Does any minimal code fail with that?

I can have only css file which I import in my entry and still getting same error

import 'styles/main.css';

:global {
  body {
    place-content: center;
  }
}

[Antonio-Laguna]

Thanks! Can you tell me your node version? @nevolgograd

[nevolgograd]

@Antonio-Laguna v16.13.0

@nevolgograd would it be possible to have access to your repo? This issue is similar as #225 but I'm having a hard time reproducing this.

I've created two files: index.css and main.css, within main.css I've put

:global {
  body {
    place-content: center;
  }
}

Then on index.css this is the only thing @import 'main.css';

The postcss.config.js file is like this:

module.exports = {
  plugins: [
    require('postcss-import'),
    require('postcss-normalize'),
    require('postcss-color-mod-function'),
    require('postcss-preset-env')
  ]
};

Ran with postcss-cli like npx postcss src/index.css -o dist/output.css and had a successful output so I'm not sure what I'm missing.

@Antonio-Laguna thanks! My repo is private, but I'll create a copy in a moment.

Thanks for preparing this @nevolgograd ! I'll take a look soon and update you on this.

Can reproduce here at least. What I can see is that this is mixing some postcss versions which isn't fine.

All of our plugins use postcss 8 but we got postcss@7.0.39 and postcss@6.0.23 too. This all seems to come from typescript-plugin-css-modules which uses things such as postcss-filter-plugins which are not upgraded to use PostCSS 8. This last plugin seems to be 4 years old without much further changes.

I'll dig a bit more to see if this is coming from our code and if it's something we could prevent.

issue is somewhere else, it seem that enabling postcss-lab-function after postcss-place leads to

  align-content: undefined;
  justify-content: undefined;
  place-content: center;

and crash comes from autoprefixer

repro

// postcss.config.js
module.exports = {
  plugins: [
    require('autoprefixer'),
    require('postcss-lab-function'),
    require('postcss-place')({}),
  ]
};

/* index.css */
body {
  place-content: center;
}

// package.json
{
  "scripts": {
    "test": "postcss index.css -o output.css"
  },
  "devDependencies": {
    "postcss": "^8.4.1",
    "postcss-cli": "^9.0.2",
    "postcss-preset-env": "^7.0.1"
  }
}

@armano2 can't seem to repro with your use case. Seems to output just fine for me, no undefined :/

Thanks! Will check what was different but can repro on your fork!

• npm dedupe seem to be solving this issue
• his seem to be related to postcss-values-parser being incorrectly hoisted
• adding "postcss-values-parser": "^6.0.1" also seem to solve this issue

in oriignal repo postcss-color-mod-function as its uses postcss-values-parse v2 and npm dosn't resolve it correctly
