Tailwind being installed even if I didn't selected it in the CLI

[GuilhermeAmado]

Which project does this relate to?

Create Tanstack App

Describe the bug

Tailwind is being installed and configured even if I didn't selected it in the CLI:

cta.json content:

{
  "framework": "react",
  "typescript": true,
  "projectName": "backoffice",
  "mode": "file-router",
  "tailwind": false,
  "packageManager": "pnpm",
  "toolchain": "biome",
  "variableValues": {},
  "git": true,
  "version": 1,
  "existingAddOns": [
    "clerk",
    "start",
    "t3env",
    "tanstack-query"
  ]
}

Steps to Reproduce the Bug or Issue

1. Run pnpm dlx create-tsrouter-app --add-ons
2. Don't select that you want to use Tailwind
3. Check the project after all is installed and configured

Expected behavior

I expected the CLI to respect my selections.

Yeah, for sure that's a bug. The issue is that the demo pages for some of these add-ons (clerk, start, tanstack-query) all assume Tailwind for formatting.

So there are two ways to go that I can think of:

1. If you've chosen add-ons then don't prompt for Tailwind because we will always add it.
2. Prompt if you want demo pages for your add-ons, in which case we add Tailwind.

I don't think it's reasonable to expect that we would have two different flavors of demo pages based on Tailwind vs not Tailwind.

@jherr Why is that? I started another project using the CLI last week with the same options and with the demo pages and I didn't had this problem. It must be something that changed recently.

I dunno, create-tsrouter-app from the beginning of having add-ons has required Tailwind support (even if you say no.)

1. If you've chosen add-ons then don't prompt for Tailwind because we will always add it.
2. Prompt if you want demo pages for your add-ons, in which case we add Tailwind.

I would go with option 2 (prompting if the user wants demo pages).

Not everyone needs or wants the demo pages, especially when it's not the first time using the tool. Prompting for demo pages makes the setup more transparent, and it's a good way to explain why Tailwind might be added.

That way, if someone chooses not to install Tailwind but opts in to demo pages, it won’t be surprising to see Tailwind included — it'll be clearly explained during the prompt.

(Edit: I've opened a PR implementing something similar to option 1, because Tailwind is actually enforced not only by selecting add-ons but also by other options, and the solution seems a bit more complex)

Yeah I just ran into this without selecting a single add-on. Hadn't had this issue before since I've been using the file-router template feature flag up to now rather than the base CLI.

pnpx create-tsrouter-app@latest . --template file-router does not install tailwind.

pnpx create-tsrouter-app@latest installs tailwind even if I say no, without any add-ons selected.

pnpx create-tsrouter-app@latest installs tailwind even if I say no, without any add-ons selected.

Exactly same issue happens here. My route is going via npx create-vite and choosing TanStack Router project which follows with running npx create-tsrouter-app@latest - no add-ons selected, biome as tooling and no for question to use Tailwind.
