svelte-check-server

A Go CLI that runs svelte-check --watch persistently and serves cached results via HTTP over a Unix socket. Get type-checking results in ~5ms instead of 3-5 seconds.

Installation

go install github.com/tylergannon/svelte-check-server@latest

Usage

# Start the server (runs svelte-check --watch in background)
svelte-check-server start -w /path/to/sveltekit/project

# Get cached results (~5ms)
svelte-check-server check -w /path/to/sveltekit/project

# Stop the server
svelte-check-server stop -w /path/to/sveltekit/project

How it works

1. start launches svelte-check --watch and parses its machine-readable output
2. Results are cached and served via HTTP over a Unix socket
3. check retrieves the latest cached results instantly
4. The server automatically restarts svelte-check when relevant files change (e.g., package.json, git branch switches)

Requirements

• svelte-check installed in your project (npm install -D svelte-check)
