Is your feature request related to a problem? Please describe. This repository currently uses Volta to pin the Node.js version. However, Volta is no longer actively maintained, and its maintainers recommend moving away from it in https://github.com/volta-cli/volta/issues/2080. It might be a good time to switch to an actively maintained alternative. Describe the solution you'd like I propose migrating our Node.js version management from Volta to Vite+ (). Vite+ can manage the Node.js version for the project, which means it can replace the current Volta setup without breaking reproducible development environments. If you are open to this idea, I would be happy to submit a PR for the migration. Describe alternatives you've considered mise is another good option, and it is actually what the Volta maintainers recommend. Either mise or Vite+ would be a solid step forward compared to sticking with an unmaintained tool. How important is this feature to you? Low to medium. The current Volta setup still works fine, so this is not urgent. Still, migrating now would save us from headaches down the road. Additional context** One thing to keep in mind is that Vite+ requires Node.js 20.19 or later, but this repository currently supports Node.js 18 and tests against it in CI. If we adopt Vite+ for CI, we would need to decide how to handle Node.js 18 support. A couple of options come to mind: Drop Node.js 18 from the CI matrix and test Node.js 20, 22, and 24 instead. Keep a separate CI job for Node.js 18 that runs without Vite+. Since updating Node.js version support goes a bit beyond just replacing Volta, I wanted to check what support policy the maintainers prefer before opening a PR. Full disclosure: I am on the Vite+ team, so I am naturally biased toward , but I am totally fine with whatever works best for this project.

(socket) svelte-preprocess@5.0.4 contains risks: Install scripts - Install scripts are run when the package is installed. The majority of malware in npm is hidden in install scripts. Accept risks of installing these packages (y/N)? See also: @SocketDev Feature requests and proposals The script will _always_ run, even for deeply nested dependencies. The script will run when someone is running from the repo, and before . Currently the install script is used to write a message to the screen which is not actually necessary for people who have this as a dependency.
Hi I didn't find anything related to this in the docs so🤷♂️ Is your feature request related to a problem? Please describe. I don't want to write every single time I want to use a style tag. Describe the solution you'd like Having options like this: Describe alternatives you've considered _ How important is this feature to you? It is so annoying, I use postcss because I use Tailwindcss, so it's necessary for me to add this lang attr. These days everyone uses Tailwind, so it will be awesome for everyone to have the option... Additional context** Please and thank you.
Describe the bug After upgrading svelte-preprocess from 6.0.3 to 6.0.4, transformer loading fails in our Rollup build setup. The failure appears to come from a change in autoProcess.js where transformer loading switched to native dynamic import without a file extension Logs To Reproduce Reproduction project https://stackblitz.com/edit/stackblitz-starters-hn2sedt5?file=package.json StackBlitz does not show the full local error output, but is shown locally when downloading the project. When diffing the files the import logic of transformers has changed abit, it's now mixing CommonJS and ESM. https://www.diffchecker.com/CeZL35Jh/ The native async import statement needs an extenstion, if I add that on row 23 it works as expected. Expected behavior Transformer imports should resolve successfully, as in 6.0.3. Information about your project:** Your operating system: (e.x. OS X 10, Ubuntu Linux 19.10, Windows XP, etc) Ubuntu 24.04.3 LTS (Windows WSL) version 6.0.4 Whether your project uses Webpack or Rollup Rollup
