When I ran `pnpm build`, I got an error like this:

```ts
file:///home/miguel/w/fuels-ts/templates/vite/tailwind.config.js:2
module.exports = {
^

ReferenceError: module is not defined

```

Hey @miguel 👋

I assume that you’re building from the root of the `fuels-ts` repository?

I have not experienced this problem and our CI is currently [passing](https://github.com/FuelLabs/fuels-ts/actions/runs/12709553538/job/35428792361).

May be worth cleaning the repository and doing a rebuild:

```bash
# This command will erase all uncommitted changes
# Please commit/stash before proceeding
git clean -fdx
pnpm install
pnpm build

```

I ran all these commands. I’m still with same error. And yes, I’m building this from the root.

Interesting.

Are you up to date with `master`?

Could you share you OS, Node Version, PNPM version?

If you rename the file to `tailwind.config.cjs` does it build successfully?

I’ve created a [PR](https://github.com/FuelLabs/fuels-ts/pull/3579) to change this file from JS to TS which should unblock you.

Please feel free to branch off `ps/chore/favour-tailwind-ts` until it’s merge.
