svelte-lsp

Svelte language server for Claude Code, providing code intelligence for Svelte components.

Supported Extensions

.svelte

claude plugin install @agentic-utils/svelte-lsp

The LSP is automatically installed via npx svelte-language-server on first use. No manual installation required.

After installing, restart Claude Code. Create a file with type errors:

<!-- test.svelte -->
<script lang="ts">
  let count: number = "not a number";
</script>

Verify the LSP is running:

ps aux | grep svelte

Edit or read the file - diagnostics should appear in system reminders:

test.svelte:
  ✘ [Line 3:7] Type 'string' is not assignable to type 'number'. [2322] (ts)
