Describe the Bug

The next-plugins repository has been deprecated, so I cannot create an issue in that repository, but this example is using a plugin from that repository. Is there a newer alternative to that plugin? I'm getting an error that's blocking me and I'm just not sure where to make the issue.

Expected Behavior

I just want to know the status of next-less.

To Reproduce

I just want to know the status of next-less.

Same question here. Also affects examples like with-ant-design-less.

Seems like the team should port over all relevant packages under the @zeit organization to this monorepo before saying that all of @zeit is deprecated.

Would also love to see less supported directly in NextJS, but here's a config I've been using in the meantime instead of next-less.

        const lessLoader = cssModules =>
            [
                !isServer && dev && 'extracted-loader',
                !isServer && MiniCssExtractPlugin.loader,
                {
                    loader: 'css-loader',
                    options: {
                        modules: {
                            mode: cssModules ? 'local' : 'global',
                            localIdentName: '[local]___[hash:base64:5]',
                            exportOnlyLocals: isServer,
                        },
                        importLoaders: 2,
                    },
                },
                {
                    loader: 'postcss-loader',
                    options: {
                        postcssOptions: {
                            plugins: ['autoprefixer'],
                        },
                    },
                },
                {
                    loader: 'less-loader',
                    options: { lessOptions: { javascriptEnabled: true } },
                },
            ].filter(Boolean);

lessLoader

How to use lessLoader in next.config.js?

[digz6666]

I'm using this plugin which works great for less files:

lessLoader

How to use lessLoader in next.config.js?

You can do something like

// Use less with CSS modules.
config.module.rules.push({
    test: /\.less$/,
    use: lessLoader(true),
})

[vbudovski]

@SimplyComplexable I've added less support to next in #23185. Once that gets merged, we will not have to deal with all these work-arounds.

@digz6666 I just hooked up that plugin as well and it does load antd fine
But im unable to get my other less files to be generated/included for the prod version of the app.
Is there additional config for importing less files in project?
As of now I only have the base config that was in the readme for next-plugin-antd-less

You can do something like this:

import styles from './home.module.less'

const Home = () => {
  return (
    <>
      <div className={styles.titleLeft}>
      </div>
    </>
  )
}

export default Home

home.module.less file:

@import '~antd/lib/style/themes/default.less';

.titleLeft {
  background-color: @border-color-base !important;
}

I have a custom index.less file where I'm overriding/making custom classes in the BEM convention so I need to import the entire custom index.less file.

I had to use a workaround that uses the less compiler to compile the less file into css and then import the generated index.css file instead since next supports regualr css out of the box.

package.json

{
  "name": "messi-ops",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "dev": "concurrently \"next dev\" \"yarn build:styles\"", // run dev server AND watch for style changes
    "build": "next build",
    "start": "next start",
    "build:styles": "less-watch-compiler ./styles ./styles index.less" // watch for any .less file changes in `styles` and output in index.css
  },
  "dependencies": {
    "antd": "^4.15.0",
    "cheerio": "^1.0.0-rc.5",
    "next": "10.1.3",
    "next-plugin-antd-less": "^0.3.0",
    "react": "17.0.2",
    "react-dom": "17.0.2"
  },
  "devDependencies": {
    "babel-plugin-import": "^1.13.3",
    "less-watch-compiler": "^1.14.6"
  }
}

this just uses less-watch-compiler to check for changes in a given folder and concurrently which runs both the dev server and styles compiler at the same time for development

Please verify that your issue can be recreated with next@canary.

Why was this issue marked with the please verify canary label?

We noticed the provided reproduction was using an older version of Next.js, instead of canary.

The canary version of Next.js ships daily and includes all features and fixes that have not been released to the stable version yet. You can think of canary as a public beta. Some issues may already be fixed in the canary version, so please verify that your issue reproduces by running npm install next@canary and test it in your project, using your reproduction steps.

If the issue does not reproduce with the canary version, then it has already been fixed and this issue can be closed.

How can I quickly verify if my issue has been fixed in canary?

The safest way is to install next@canary in your project and test it, but you can also search through closed Next.js issues for duplicates or check the Next.js releases.

My issue has been open for a long time, why do I need to verify canary now?

Next.js does not backport bug fixes to older versions of Next.js. Instead, we are trying to introduce only a minimal amount of breaking changes between major releases.

What happens if I don't verify against the canary version of Next.js?

An issue with the please verify canary that receives no meaningful activity (e.g. new comments that acknowledge verification against canary) will be automatically closed and locked after 30 days.

If your issue has not been resolved in that time and it has been closed/locked, please open a new issue, with the required reproduction, using next@canary.

I did not open this issue, but it is relevant to me, what can I do to help?

Anyone experiencing the same issue is welcome to provide a minimal reproduction following the above steps. Furthermore, you can upvote the issue using the 👍 reaction on the topmost comment (please do not comment "I have the same issue" without repro steps). Then, we can sort issues by votes to prioritize.

I think my reproduction is good enough, why aren't you looking into it quicker?

We look into every Next.js issue and constantly monitor open issues for new comments.

However, sometimes we might miss one or two due to the popularity/high traffic of the repository. We apologize, and kindly ask you to refrain from tagging core maintainers, as that will usually not result in increased priority.

Upvoting issues to show your interest will help us prioritize and address them as quickly as possible. That said, every issue is important to us, and if an issue gets closed by accident, we encourage you to open a new one linking to the old issue and we will look into it.
