Examples

Accessing Nuxt Vite Config

If you are building an integration that needs access to the runtime Vite or webpack config that Nuxt uses, it is possible to extract this using Kit utilities.

Some examples of projects doing this already:

• histoire
• nuxt-vitest
• @storybook-vue/nuxt

Here is a brief example of how you might access the Vite config from a project; you could implement a similar approach to get the webpack configuration.

import { loadNuxt, buildNuxt } from '@nuxt/kit'// https://github.com/nuxt/nuxt/issues/14534async function getViteConfig() {  const nuxt = await loadNuxt({ cwd: process.cwd(), dev: false, overrides: { ssr: false } })  return new Promise((resolve, reject) => {    nuxt.hook('vite:extendConfig', (config, { isClient }) => {      if (isClient) {        resolve(config)        throw new Error('_stop_')      }    })    buildNuxt(nuxt).catch((err) => {      if (!err.toString().includes('_stop_')) {        reject(err)      }    })  }).finally(() => nuxt.close())}const viteConfig = await getViteConfig()console.log(viteConfig)
