# Vitest Workspaces

In a monorepo with a SvelteKit app, running coverage with `@vitest/coverage-istanbul` does not work. Works fine with `@vitest/coverage-v8` but I need istanbul (required by [`@cloudflare/vitest-pool/workers`](https://www.npmjs.com/package/@cloudflare/vitest-pool-workers))

## Reproduction

1. Clone repo

2. Install dependencies (`bun install`)

3. Run test script (`bun run test`) - everything passes

4. Run coverage script (`bun run coverage`) 

Tests pass but collecting coverage fails with the following error:

```shell

SyntaxError: /Users/ernest/Projects/Repros/vitest-workspaces-istanbul/packages/web/src/routes/+page.svelte: Support for the experimental syntax 'jsx' isn't currently enabled (1:1):

Add @babel/preset-react (https://github.com/babel/babel/tree/main/packages/babel-preset-react) to the 'presets' section of your Babel config to enable transformation.

If you want to leave it as-is, add @babel/plugin-syntax-jsx (https://github.com/babel/babel/tree/main/packages/babel-plugin-syntax-jsx) to the 'plugins' section to enable parsing.

If you already added the plugin for this syntax to your config, it's possible that your config isn't being loaded.

You can re-run Babel with the BABEL_SHOW_CONFIG_FOR environment variable to show the loaded configuration:

        npx cross-env BABEL_SHOW_CONFIG_FOR=/Users/ernest/Projects/Repros/vitest-workspaces-istanbul/packages/web/src/routes/+page.svelte 

See https://babeljs.io/docs/configuration#print-effective-configs for more info.
