Prettier in Svelte 5 does not recognize <script module>, preferring the deprecated <script context='module'>

[hmprt]

Svelte allows for components with two script tags, so long as one is a <script module>.

<script lang='ts' module>
...
<script lang='ts'>

If you do this however, prettier complains and will stop formatting documents, saying:
ParseError: A component can only have one instance-level <script> element

The solution is to use deprecated syntax to achieve the same result:

<script lang='ts' context='module'>
<script lang='ts'> 

However this produces a svelte linter warning at the top of the documents:
context="module" is deprecated, use the 'module' attribute instead
After making this change, prettier formatting starts working again.

This sounds like prettier is using a different Svelte version to format than what you have in your project. Make sure to follow these instructions in case you did install prettier or prettier-plugin-svelte into your local project.

Otherwise I need a reproduction to properly look into this.

Appreciate your swift response!

I've tried pegging my prettier-plugin-svelte version to 3.3.3 with no effect. It seems specifically to have issues with svelte 5 features like runes, too.

First message should be minimum viable reproduction if used in a blank .svelte file. Does that format nicely for you?
