npm run dev --host network: not exposed

Question

I want to expose my svelte app on LAN using the npm run dev --host command but it shows:

> frontend@0.0.1 dev
> svelte-kit dev


  SvelteKit v1.0.0-next.295

  local:   http://localhost:3000
  network: not exposed

  Use --host to expose server to other devices on this network

Answer 1

You have to add -- before the actual flag:

npm run dev -- --host

And it should output:

> project@0.0.1 dev
> svelte-kit dev "--host"


  SvelteKit v1.0.0-next.316

  local:   http://localhost:3000
  network: http://***.***.**.**:3000

  Note that all files in the following directories will be accessible to anyone on your network: src/lib, src/routes, .svelte-kit, src, node_modules
