How to add tailwindcss to KotlinJS

Question

I am unable to add the tailwindcss library to my KotlinJS project. I tried multiple things.

I have multiple dependencies defined in my build.gradle.kts

implementation(npm("postcss", "latest"))
implementation(npm("postcss-loader", "latest"))
implementation(npm("tailwindcss", "1.8.10"))

I tried creating a tailwindcss.js in my webpack.config.d with this content

config.module.rules.push({
        test: /\.css$/i,
        use: [
            'style-loader',
            'css-loader',
            {
                loader: 'postcss-loader',
                options: {
                    postcssOptions: {
                        plugins: [
                            [
                                'tailwindcss'
                            ],
                        ],
                    },
                },
            }
        ]
    }
);

But that doesn't do anything. I also tried modifying this with multiple options, but I was never able to get tailwindcss to compile. I also tried disabling and enabling the KotlinJS CSS support in build.gradle.kts

I can't find any info on how to add postcss to KotlinJS project.

Thank you for any help.

The accepted answer seems to not work anymore. Also, using the Node Gradle plugin is sub-optimal (KotlinJS already maintains its own package.json and yarn installation).

I managed to get Tailwind to work with KotlinJS thanks for this repository (GitHub) with a few small updates that you can find here (GitLab).
