Install

npm install --save-dev vite-imagetools

Usage

import { defineConfig } from 'vite'
import { imagetools } from 'vite-imagetools'

export default defineConfig({
  plugins: [imagetools()]
})

import Image from 'example.jpg?w=400&h=300&format=webp'

You can also import a directory of images using Vite's import.meta.glob with its query option.

Options

defaultDirectives

• Optional defaultDirectives: URLSearchParams | (url: URL) => URLSearchParams

This option allows you to specify directives that should be applied by default to every image. You can also provide a function, in which case the function gets passed the asset ID and should return an object of directives. This can be used to define all sorts of shorthands or presets.

example

import { defineConfig } from 'vite'
import { imagetools } from 'vite-imagetools'

export default defineConfig({
  plugins: [
    imagetools({
      defaultDirectives: (url) => {
        if (url.searchParams.has('spotify')) {
          return new URLSearchParams({
            tint: 'ffaa22'
          })
        }
        return new URLSearchParams()
      }
    })
  ]
})
