Vite
Qwik leverages Vite to provide a fast development experience. Vite is a build tool that serves your code via native ES Modules during development. This means that it doesn't need to bundle your code or transpile it to work in the browser. It also comes with lightning fast hot module replacement (HMR) that updates your browser instantly when you make changes to your code.
Configuration
After scaffolding a new Qwik project, you'll find a vite.config.js
file in the root of your project. This is where you can configure Vite.
Vite Plugins
Qwik comes with two plugins that make it easy to use Vite with Qwik and Qwik City.
import { defineConfig } from 'vite';
import { qwikCity } from '@builder.io/qwik-city/vite';
import { qwikVite } from '@builder.io/qwik/optimizer';
import tsconfigPaths from 'vite-tsconfig-paths';
export default defineConfig(() => {
return {
plugins: [qwikCity(), qwikVite(), tsconfigPaths()],
};
});
qwikVite()
To modify the configuration, you can pass an object to the qwikVite
function. Possible options are:
debug
/**
* Prints verbose Qwik plugin debug logs.
* Default `false`
*/
debug?: boolean;
entryStrategy
/**
* The Qwik entry strategy to use while bundling for production.
* During development the type is always `hook`.
* Default `{ type: "smart" }`)
*/
entryStrategy?: EntryStrategy;
srcDir
/**
* The source directory to find all the Qwik components. Since Qwik
* does not have a single input, the `srcDir` is use to recursively
* find Qwik files.
* Default `src`
*/
srcDir?: string;
tsconfigFileNames
/**
* List of tsconfig.json files to use for ESLint warnings during development.
* Default `['tsconfig.json']`
*/
tsconfigFileNames?: string[];
vendorRoots
/**
* List of directories to recursively search for Qwik components or Vendors.
* Default `[]`
*/

ssr
ssr?: {
/**
* The entry point for the SSR renderer. This file should export

*/
input?: string;
/**
* Output directory for the server build.
* Default `dist`
*/
outDir?: string;
/**
* The SSR build requires the manifest generated during the client build.
* By default, this plugin will wire the client manifest to the ssr build.
* However, the `manifestInput` option can be used to manually provide a manifest.
* Default `undefined`
*/
manifestInput?: QwikManifest;
};
optimizerOptions
/**
* Options for the Qwik optimizer.
* Default `undefined`
*/
optimizerOptions?: OptimizerOptions;
transformedModuleOutput
/**
* Hook that's called after the build and provides all of the transformed
* modules that were used before bundling.
*/
transformedModuleOutput?:

| null;
devTools
devTools?: {
/**
* Validates image sizes for CLS issues during development.
* In case of issues, provides you with a correct image size resolutions.
* If set to `false`, image dev tool will be disabled.
*/
imageDevTools?: boolean | true;
/**
* Press-hold the defined keys to enable qwik dev inspector.
* By default the behavior is activated by pressing the left or right `Alt` key.
* If set to `false`, qwik dev inspector will be disabled.

clickToSource?: string[] | false;

qwikCity()
To modify the configuration, you can pass an object to the qwikCity
function. Possible options are:
routesDir
/**

Troubleshooting
Before creating an issue on the Qwik repository please check the Troubleshooting
section of the Vite documentation and make sure you're using the recommended version.
