Vite - change ouput directory of assets

Question

By default Vite generates files in the source directory under dist.

my-app/
├─ node_modules/
├─ dist/
│  ├─ assets/
|  |    | index.js
|  |    | index.css        
│  ├─ index.html
├─ index.html
├─ main.js
├─ style.scss
├─ package.json

I need to create a different folder for js and css files under assets. In other words, I need to put js and css filer under /assets/js and /assets/css folders respectively.

my-app/
├─ node_modules/
├─ dist/
│  ├─ assets/
|  |    |-js/
|  |    |   index.js
|  |    |-css/
|  |    |  index.css  

This is my config file.

import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import svgrPlugin from "vite-plugin-svgr";

// https://vitejs.dev/config/
export default defineConfig({
  base: "./",
  plugins: [react(), svgrPlugin()],
  server: {
    open: true,
    proxy: {
      "/base": {
        target: "http://localhost:19000",
        changeOrigin: true,
        rewrite: (path) => path.replace(/^\/base/, ""),
      },
    },
  },
});

How to do so?

Answer 1

The output filenames are configured in Rollup with build.rollupOptions:

1. Set output.assetFileNames to configure the asset filenames (for media files and stylesheets).

2. Set output.chunkFileNames to configure the vendor chunk filenames.

3. Set output.entryFileNames to configure the index.js filename.

// vite.config.js
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [react()],
  build: {
    rollupOptions: {
      output: {
        1️⃣
        assetFileNames: (assetInfo) => {
          let extType = assetInfo.name.split('.').at(1);
          if (/png|jpe?g|svg|gif|tiff|bmp|ico/i.test(extType)) {
            extType = 'img';
          }
          return `assets/${extType}/[name]-[hash][extname]`;
        },
        2️⃣
        chunkFileNames: 'assets/js/[name]-[hash].js',
        3️⃣
        entryFileNames: 'assets/js/[name]-[hash].js',
      },
    },
  },
});

If you use @font-face in your css file, it masses up. You may need to put fonts in the same folder as the css files.

I have used woff and woff2 fonts

    rollupOptions: {
      output: {
        assetFileNames: (assetInfo) => {
          var info = assetInfo.name.split(".");
          var extType = info[info.length - 1];
          if (/png|jpe?g|svg|gif|tiff|bmp|ico/i.test(extType)) {
            extType = "img";
          } else if (/woff|woff2/.test(extType)) {
            extType = "css";
          }
          return `static/${extType}/[name]-[hash][extname]`;
        },
        chunkFileNames: "static/js/[name]-[hash].js",
        entryFileNames: "static/js/[name]-[hash].js",
      },
    }

Answer 3

Thanks tony19, this work properly as well, but i has build error: [vite:build-html] assetInfo.name.split(...).at is not a function

I simple change

assetInfo.name.split('.').at(1);

to

assetInfo.name.split('.')[1];

Suddenly someone will need it.
I have a separate folder configured in my assembly for different types of files.
All that is required is: npm i sass, npm i vite
vite.config.js

import { defineConfig } from 'vite';

export default defineConfig({
  root: './src',
  build: {
    outDir: '../dist',
    assetsDir: '', // Leave `assetsDir` empty so that all static resources are placed in the root of the `dist` folder.
    assetsInlineLimit: 0,
    rollupOptions: {
      // input: {
      //   // Uncomment if you need to specify entry points for .html files
      //   index: resolve(__dirname, 'src/index.html'),
      //   myworks: resolve(__dirname, 'src/my-works.html'),
      //   thoughts: resolve(__dirname, 'src/thoughts.html'),
      //   about: resolve(__dirname, 'src/about.html'),
      //   contact: resolve(__dirname, 'src/contact.html'),
      // },
      output: {
        entryFileNames: 'js/[name]-[hash].js', // If you need a specific file name, comment out
        chunkFileNames: 'js/[name]-[hash].js', // these lines and uncomment the bottom ones
        // entryFileNames: chunk => {
        //   if (chunk.name === 'main') {
        //     return 'js/main.min.js';
        //   }
        //   return 'js/main.min.js';
        // },
        assetFileNames: assetInfo => {
          const info = assetInfo.name.split('.');
          const extType = info[info.length - 1];
          if (/\.(png|jpe?g|gif|svg|webp|webm|mp3)$/.test(assetInfo.name)) {
            return `media/[name]-[hash].${extType}`;
          }
          if (/\.(css)$/.test(assetInfo.name)) {
            return `css/[name]-[hash].${extType}`;
          }
          if (/\.(woff|woff2|eot|ttf|otf)$/.test(assetInfo.name)) {
            return `fonts/[name]-[hash].${extType}`;
          }
          return `[name]-[hash].${extType}`;
        },
      },
    },
  },
});
