latest version windows, vsc,
"tailwindcss": "^4.0.0-beta.9",

if you have today new version @tailwindcss/[email protected]
https://www.npmjs.com/package/@tailwindcss/language-server/v/0.12.18

autocomplete broken

if you downgrade to prev version 0.0.27 (yes crazy number , yes its prev version :D)
https://www.npmjs.com/package/@tailwindcss/language-server/v/0.0.27
all work fine

Yeah I bumped the version number to match the VSCode extension so they all stay in sync. I'll take a look.

@alxNoComment Could you provide a reproduction?

also for me with windows 11
I tried to install @tailwindcss/language-server in develop dependency and configure the plugin to use it, but anything changes.

My webstorm version is WebStorm 2024.3.2.1 and Tailwind CSS bundled 243.23654.157

The error that appear in the logs is:

2025-02-06 13:27:42,625 [ 30497] INFO - #c.i.p.l.i.LspServerImpl - TailwindLspServerDescriptor@SoftCollie - front(Running;25): No response from the server in 10000ms for: com.intellij.platform.lsp.impl.LspRequestExecutorImpl$$Lambda/0x000001a47ead3308

I tried also to clean all cache, but nothing is different.

my tailwind.config.js:

/** @type {import('tailwindcss').Config} */
module.exports = {
    content: [
        "./src/**/*.{html,ts}",
    ],
    theme: {
        extend: {},
    },
    plugins: [
        require("tailwindcss"),
        require("autoprefixer"),
    ],
};

Important

Switching to WebStorm 2024.2.5 running well again, is a issue related to last version

Hey! I'm not seeing this with the latest version of the language server (v0.14.4), WebStorm (2024.3.2.1), and Tailwind CSS (4.0.6).

I had to manually install and point WebStorm to an installation of the language server tho (not sure if there's a way to get it to update its bundled version).
