If you limit the warning, does the issue go? i think you only have removed the warning and the issue is till there, because it will still give you error when you try to deploy it. |

Setting a warning limit doesn't do anything but temporarily hide the issue. Upon deployment, you will still get the same warning and it will fail to deploy. |

That wouldnt really solve anything, just hide the warning. If you actually want to fix it you should use the fixes in the forums he linked in the first posts. |

I have quite hard to imagine that the error you are getting would possible have anything to do with the file being over 500kib. |

After adding this on vite.config.js it's fixed build: {
rollupOptions: {
output:{
manualChunks(id) {
if (id.includes('node_modules')) {
return id.toString().split('node_modules/')[1].split('/')[0].toString();
}
}
}
}
}Full File is like export default defineConfig({
plugins: [
vue(),
laravel({
input: ['resources/js/app.js'],
refresh: true,
}),
i18n(),
],
resolve: {
alias: {
vue: 'vue/dist/vue.esm-bundler.js',
ziggy: path.resolve('vendor/tightenco/ziggy/dist/vue.es.js'),
},
},
build: {
rollupOptions: {
output:{
manualChunks(id) {
if (id.includes('node_modules')) {
return id.toString().split('node_modules/')[1].split('/')[0].toString();
}
}
}
}
}
}); |

True, this config does reduce the chunk size, but it screws up the CSS :( |

600KB chunk is OK. But It's much better to have 20 of 600 KB chunks than one with 10 MB, because in the 1st case you can use dynamic/lazy imports, and upload only needed files. Commonly you don't need much of the 10 MB, up to 2 MB is enough. |

Vite.js uses Rollup and esbuild in the background. esbuild has not yet released a v1 whereas it's safe to say Rollup is a well supported tool. I am wondering if Vite.js is worth all the complexity when I could simply use Rollup by itself. |

Without knowing the details of your specific use-case, then the decision is yours to make. Though I’d recommend reading any articles on what Vite adds to the mix before deciding. One such article: https://verpex.com/blog/website-tips/vite-vs-rollup-a-detailed-comparison-for-web-development |

I add this build section, maybe not best, but work fine for me： build: {
rollupOptions: {
output: {
manualChunks(id: string) {
if (id.indexOf('node_modules') !== -1) {
const basic = id.toString().split('node_modules/')[1];
const sub1 = basic.split('/')[0];
if (sub1 !== '.pnpm') {
return sub1.toString();
}
const name2 = basic.split('/')[1];
return name2.split('@')[name2[0] === '@' ? 1 : 0].toString();
}
}
}
}

With more mature variable names: output: {

if (id.includes('node_modules')) {
const modulePath = id.split('node_modules/')[1];
const topLevelFolder = modulePath.split('/')[0];
if (topLevelFolder !== '.pnpm') {
return topLevelFolder;
}
const scopedPackageName = modulePath.split('/')[1];
const chunkName = scopedPackageName.split('@')[scopedPackageName.startsWith('@') ? 1 : 0];
return chunkName;
}

I had to deal with something of the sorts with my Quasar project and documented an approach. Basically this involves using the Rollup Visualiser to look at how the chunks are assembled and then using manualChunks to tune the chunks. The only thing is if you have a single source file that results in a large chunk, then maybe looking at splitting up the source file might be necessary? Of course this is not always possible, such as if you are depending on a third-party package. There are other approaches too, via chunking strategies. The one thing I haven't quite worked out is how to mix this with dynamic import hints? |

I used a modified manual chunks function inspired from above answers. This creates separate js files for huge libraries in your project, and rest all other codes are bundled into You can use this build config to get a idea of which are the big libraries in your code: Final output build:

I was running a Remix application and found it strange that one of my JS files was 914KB in size! I pinpointed my problem by running vite-bundle-visualizer. It showed me that highlight.js, a package I'm using to highlight code, was bundling itself, contributing to the gigantic file size. 
The highlight is the highlight.js package contributing to the overall bundle size To do the same, navigate to your project's root directory (where the vite.config.ts file is: Run: And see which packages Vite includes. Note:Not all packages you can
Example: (Actual production code)
This is a generic component in which I centralize all of my icons in a single place, and then call them via a map key. Problem: Solution 1: This allowed each icon to be solicited only when needed. Problem 2: Solution 2: I also sprinkle some IntersectionObserver to even further delay the import. Bringing everything together (simplified): const iconMap = {
copy: () =>
import("./icon-exports/AiOutlineCopy").then((module) => ({
default: module.AiOutlineCopy,
})),
// Other icons omitted
awsLambda: () =>
import("./icon-exports/AwsLambda").then((module) => ({
default: module.AwsLambda,
})),
};
export type ColorVariant = "white" | "dark" | "red";
export const colorMap: Record<ColorVariant, string> = {
white: "#fff",
dark: "#1e2329",
red: "#e33122",
};
export type IconType = keyof typeof iconMap;
export type IconProps = {
icon: IconType;
color?: ColorVariant;
stroke?: ColorVariant;
fill?: ColorVariant;
size?: number;
width?: string;
height?: string;
customColor?: string;
className?: string;
};
export const Icon: React.FC<IconProps> = (props) => {
const { icon, color, stroke, customColor, size = 24, ...otherProps } = props;
const [loaded, setLoaded] = useState(false);
const { isIntersecting, setRef } = useIntersectionObserver({
root: null,
rootMargin: "0px",
threshold: 0.1,
});
useEffect(() => {
if (isIntersecting) {
setLoaded(true);
}
}, [isIntersecting]);
const Element = loaded ? lazy(iconMap[icon]) : null;
const width = `${size}px`;
const height = `${size}px`;
const colors = {
stroke: stroke ? colorMap[stroke] : undefined,
color: customColor ? customColor : color ? colorMap[color] : undefined,
};
return (
<div ref={setRef} style={{ width, height }}>
{loaded && Element ? (
<Suspense fallback={<div style={{ width, height }} />}>
<Element size={size} {...otherProps} {...colors} />
</Suspense>
) : (
<div style={{ width, height }} />
)}
</div>
);
};Intersection Observer Hook: import { useEffect, useState } from "react";
export const useIntersectionObserver = (options: IntersectionObserverInit) => {
const [isIntersecting, setIsIntersecting] = useState(false);
const [ref, setRef] = useState<HTMLElement | null>(null);
useEffect(() => {
if (!ref) return;
const observer = new IntersectionObserver(([entry]) => {
if (entry.isIntersecting) {
setIsIntersecting(true);
observer.disconnect();
}
}, options);
observer.observe(ref);
return () => observer.disconnect();
}, [ref, options]);
return { isIntersecting, setRef };
};Then, in Creating this indirection will allow Vite to import only the AwsLambda into its own JS file, and render it only when needed |

Beta Was this translation helpful? Give feedback.

You need to tune your bundling. As an example (we use Quasar for our project): function manualChunks (id) {
if (id.includes('/vue/') || id.includes('/@vue/')) {
return 'vue';
} else if (id.includes('/quasar/')) {
return 'quasar';
} else if (id.includes('/markdown-it/')) {
return 'md';
} else if (id.includes('/@ac-dev/')) {
return 'geo';
} else if (id.includes('node_modules')) {
return 'vendor';
} else {
return 'main';
}
}And then use this with your rollup options: For pure Vite: rollupOptions: {
output: {
manualChunks
}
}If using with Quasar: extendViteConf (viteConf) {
viteConf.build = mergeConfig(viteConf.build, {
rollupOptions: {
output: {
manualChunks
}
}
});
},You should also leverage the visualizer plugin to tune the bundling for your project. Note sometimes trying to get something below 500KB is a challenge. For example, in another project I wasn't able to find a working solution for ThreeJS, but I haven't tried again recently. |
