Not working with SvelteKit

[vigneshksaithal]

Steps to reproduce

Task: Migrate an existing SvelteKit(using Vite) project to Farm.

Run pnpm add @farmfe/core @farmfe/cli. Add this code to farm.config.ts.

import { sveltekit } from "@sveltejs/kit/vite";

export default defineConfig({
  vitePlugins: [sveltekit()],
  compilation: {
    input: {
      index: "./src/app.html",
    },
  },
});
Run pnpm farm build.

### What is expected?

Should build the app.

### What is actually happening?

I am getting this error

Potential Causes:
1.The module have syntax error.
2.This kind of module is not supported, you may need plugins to support it

@sveltejs/kit/vite are deeply integrated with Vite, it's not compatible with Farm. You can use @sveltejs/vite-plugin-svelte instead

[vigneshksaithal]

@wre232114 tried with @sveltejs/vite-plugin-svelte but, still getting the same error.

[wre232114]

It seems there are syntax issues in app.html, some plugins that handles app.html may be missing. What's your original vite.config.ts?

[vigneshksaithal]

@wre232114 Here is my vite.config.ts

import { sveltekit } from "@sveltejs/kit/vite";
import { defineConfig } from "vite";

export default defineConfig({
  plugins: [sveltekit()],
});

With Vite it is working fine.

Here is app.html

<!doctype html>
<html lang="en">
    <head>
        <meta charset="utf-8" />
        <link rel="icon" href="%sveltekit.assets%/favicon.png" />
        <meta name="viewport" content="width=device-width" />

        />

        %sveltekit.head%
    </head>

    <body data-sveltekit-preload-data="hover">
        <div style="display: contents">%sveltekit.body%</div>
    </body>
</html>

[wre232114]

I checked source code of@sveltejs/kit/vite, it is not compatible with Farm cause it uses Vite-specific APIs like vite.ssrLoadModules

[vigneshksaithal]

Any other way of using it in SvelteKit?

[wre232114]

No for now, a farm-plugin-sveltekit is needed, I hope it can be implemented as soon as possible

[hayd1n]

Why close this issue?

[ErKeLost]

hi @CRT-HAO We have added support for the vite svelte plugin. Do you have any other needs?

[wre232114]

I'll reopen this issue, it would be closed when the plugin is compatible or a alternative plugin is provided

Bump. Haven't dug into the code yet. but here is my error:

@KyleFontenot you are using sveltekit with the svelte only plugin. (%sveltekit.body%)

As far as I understand there is no way to use farm with sveltekit currently. Any ETA about this? SK is my main framework

[wre232114]

It seems that sveltekit plugin is deeply integrated with Vite, We don't have a ETA
