regression: build fails with SK 2.0 and svelte-highlight >=7.4.3

[wbhob]

When attempting to build my app using SvelteKit 2.0 and Vite 5.0, the following error occurs. The last version that builds successfully is 7.4.2.

[commonjs--resolver] Missing "./styles" specifier in "svelte-highlight" package

Can you ensure this is the latest patch version v7.4.7?

[metonym]

The sveltekit example works for me – both dev and building using the node adapter. It's using SvelteKit v2.

[wbhob]

it appears that at one point, 'svelte-highlight/styles' was a valid import, but now it is not, so that was a major breaking change labeled as a patch release. I've updated the code to import the specific stylesheet and it's now working

[metonym]

I'll take a look.

@wbhob Thank you for flagging this.

Technically, it wasn't a breaking change as the barrel export files still exist (e.g., svelte-highlight/styles/index.js). The bug was that the exports map did not account for these entry points.

I published a fix in v7.4.8, which supports additional import methods:

// Base import for styles/languages
import { _default } from "svelte-highlight/styles";
import { _1c } from "svelte-highlight/languages";

// Explicit index
import { _default } from "svelte-highlight/styles/index";
import { typescript } from "svelte-highlight/languages/index";

// Explicit extension
import lang from "svelte-highlight/languages/1c.js"
import style from "svelte-highlight/styles/3024.js";

No TS errors in my IDE; Vite was able to resolve these imports in vite dev and vite build.
