Vite Image Optimizer

Plugin for Vite to optimize all images assets using Sharp.js and SVGO at build time.

• Optimize SVG assets using SVGO and pass custom configs.
• Optimize Raster assets (png, jpeg, gif, tiff, webp, avif) using Sharp.js with the option to pass custom configs for each extension type.
• Option to process all assets from your public directory defined in the bundler.
• Configure test, include, and exclude to filter assets.
• Caching support to avoid re-optimization (optional)
• Skips processing assets if their optimized size is greater than their original size.
• Log the optimization stats showing the before and after size difference, ratio and total savings (optional)

This plugin is based on the awesome image-minimizer-webpack-plugin for Webpack. I wanted to combine the optimization capabilities of Sharp.js and SVGO in a single package and I couldn't find a plugin for Vite that could accomplish this. I initially thought of adding squoosh and imagemin support as well but dropped the idea since they are no longer maintained.

You can add it as a dev dependency to any of the package managers (NPM, Yarn, PNPM)

Supports Vite >=3 and Node >=14

npm install vite-plugin-image-optimizer --save-dev

Warning

sharp and svgo don't come installed as part of the package. You will have to install them manually and add it as a dev dependency. This is a design decision so you can choose to skip installing sharp if you only want to optimize svg assets using svgo and vice versa.

npm install sharp --save-dev

npm install svgo --save-dev

import { ViteImageOptimizer } from 'vite-plugin-image-optimizer'; import { defineConfig } from 'vite'; export default defineConfig(() => { return { plugins: [ ViteImageOptimizer({ /* pass your config */ }), ], }; });

The default configuration is made for lossless compression of image assets.

Type: RegExp

Default: /\.(jpe?g|png|gif|tiff|webp|svg|avif)$/i

Test to match files against.

Type: String | RegExp | Array<string>

Default: undefined

Files to exclude. RegExp can be used on the source path to exclude a particular folder (exclude: /textures/).

Type: String | RegExp | Array<string>

Default: undefined

Files to include. RegExp can be used on the source path to include a particular folder (include: /textures/).

Warning

This will override any options set in test and exclude and has a higher preference. Use this option if you want to include specific assets only.

Type: boolean

Default: true

Include all assets within the public directory defined in Vite. When true it will recursively traverse the directory and optimize all the assets.

Type: boolean

Default: true

Logs the optimization stats to terminal output with file size difference in kB, percent increase/decrease and total savings.

Type: boolean

Default: true

Logs the optimization stats or errors with ansi colors in the terminal. Set it to false for shells that don't support color text.

Type: SVGOConfig

Default:

{ multipass: true, plugins: [ { name: 'preset-default', params: { overrides: { cleanupNumericValues: false, removeViewBox: false, // https://github.com/svg/svgo/issues/1128 }, cleanupIDs: { minify: false, remove: false, }, convertPathData: false, }, }, 'sortAttrs', { name: 'addAttributesToSVGElement', params: { attributes: [{ xmlns: 'http://www.w3.org/2000/svg' }], }, }, ] }

Config object to pass to SVGO, you can override it with your custom config.

Type: PngOptions

Default:

{ // https://sharp.pixelplumbing.com/api-output#png quality: 100, }

Config object to pass to Sharp.js for assets with png extension

Type: JpegOptions

Default:

{ // https://sharp.pixelplumbing.com/api-output#jpeg quality: 100, }

Config object to pass to Sharp.js for assets with jpg or jpeg extension

Type: GifOptions

Default:

{ // https://sharp.pixelplumbing.com/api-output#gif }

Config object to pass to Sharp.js for assets with gif extension

Type: TiffOptions

Default:

{ // https://sharp.pixelplumbing.com/api-output#tiff quality: 100, }

Config object to pass to Sharp.js for assets with tiff extension

Type: WebpOptions

Default:

{ // https://sharp.pixelplumbing.com/api-output#webp lossless: true, }

Type: AvifOptions

Default:

{ // https://sharp.pixelplumbing.com/api-output#avif lossless: true, }

Type: boolean

Default: false

Cache assets in cacheLocation. When enabled, reads and writes asset files with their hash suffix from the specified path.

Type: String

Default: undefined

Path to the cache directory. Can be used with GitHub Actions and other build servers that support cache directories to speed up consecutive builds.
