Help me to add 'cssHash' to 'compilerOptions' in sveltkit idk where ?

[good-dev-student]

Hello,

please help me

The goal is to chnage classes like this :

<div class="xx s-OTmmHBhb3fXp" data-svelte-h="svelte-g8ovga">c</div>

to this :

<div class="xx s-OTmmHBhb3fXp" data-svelte-h="meaw-g8ovga">c</div>

I add the code to svelte.config.js :

compilerOptions: {
		cssHash: ({ hash, name, filename, css }) => {
			// default behavior
			//return `svelte-${hash(css)}`;
		
			// stable hashes for HMR
			return `wohh-${hash(filename)}`;
		  }

	},

Final code like this:

import adapter from '@sveltejs/adapter-auto';
import { vitePreprocess } from '@sveltejs/kit/vite';

/** @type {import('@sveltejs/kit').Config} */
const config = {
+	compilerOptions: {
+		cssHash: ({ hash, name, filename, css }) => {
+			// default behavior
+			//return `svelte-${hash(css)}`;
+		
+			// stable hashes for HMR
+			return `svelte-${hash(filename)}`;
+		  }
+
	},
	// Consult https://kit.svelte.dev/docs/integrations#preprocessors
	// for more information about preprocessors
	preprocess: [vitePreprocess({})],

	kit: {
		// adapter-auto only supports some environments, see https://kit.svelte.dev/docs/adapter-auto for a list.
		// If your environment is not supported or you settled on a specific environment, switch out the adapter.
		// See https://kit.svelte.dev/docs/adapters for more information about adapters.
		adapter: adapter()
	},
};

export default config;

i will see WARNING like thsis:

[vite-plugin-svelte] The following Svelte compilerOptions are controlled by vite-plugin-svelte and essential to its functionality. User-specified values are ignored. Please remove them from your configuration: cssHash

in vite.config.ts not working

NOT like this:

import { sveltekit } from '@sveltejs/kit/vite';
import { defineConfig } from 'vitest/config';

export default defineConfig({
	plugins: [
		sveltekit({
			compilerOptions: {
				cssHash: ({ hash }) => hash('foo')
			}
		})
	],

	test: {
		include: ['src/**/*.{test,spec}.{js,ts}']
	},

	css: {
		preprocessorOptions: {
			scss: {
				additionalData: '@use "src/scss/variables.scss" as *;'
			}
		}
	}
});

or this:

import { sveltekit } from '@sveltejs/kit/vite';
import { defineConfig } from 'vitest/config';

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

	test: {
		include: ['src/**/*.{test,spec}.{js,ts}']
	},

	css: {
		preprocessorOptions: {
			scss: {
				additionalData: '@use "src/scss/variables.scss" as *;'
			}
		}
	},
	compilerOptions: {
		cssHash: ({ hash }) => hash('foo')
	}
});

And if i want to change the cssHash on dev also dosen't work idk why and why work only on prod?

import adapter from '@sveltejs/adapter-auto';
import { vitePreprocess } from '@sveltejs/kit/vite';

const compilerOptions = {};

// if (process.env.NODE_ENV === 'production') {
    compilerOptions.cssHash = ({ hash, css }) => `ai-${hash(css)}`;
// }

/** @type {import('@sveltejs/kit').Config} */
const config = {
    // Consult https://kit.svelte.dev/docs/integrations#preprocessors
    // for more information about preprocessors
    preprocess: [vitePreprocess({})],

    kit: {
        // adapter-auto only supports some environments, see https://kit.svelte.dev/docs/adapter-auto for a list.
        // If your environment is not supported or you settled on a specific environment, switch out the adapter.
        // See https://kit.svelte.dev/docs/adapters for more information about adapters.
        adapter: adapter()
    },
    compilerOptions
};

export default config;
