### Configuring
When running `electron-vite` from the command line, electron-vite will automatically try to resolve a config file named `electron.vite.config.js` inside project root. The most basic config file looks like this:

}
```
### Use HMR in Renderer
In order to use the renderer process HMR, you need to use the `environment variables` to determine whether the window browser loads a local html file or a local URL.
```js
function createWindow() {
// Create the browser window
const mainWindow = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
preload: path.join(__dirname, '../preload/index.js')
}
})
// Load the remote URL for development or the local html file for production
if (!app.isPackaged && process.env['ELECTRON_RENDERER_URL']) {
mainWindow.loadURL(process.env['ELECTRON_RENDERER_URL'])
} else {
mainWindow.loadFile(path.join(__dirname, '../renderer/index.html'))
}
}
```
### Hot Reloading
Hot reloading refers to quickly rebuilding and restarting the Electron app when the main process or preload scripts module changes. In fact, it's not really hot reloading, but similar. It also brings a good development experience to developers.
There are two ways to enable it:
1. Use CLI option `-w` or `--watch`, e.g. `electron-vite dev --watch`. This is the preferred way, it's more flexible.
2. Use configuration option `build.watch` and set to `{}`. In addition, more watcher options can be configured, see [WatcherOptions](https://rollupjs.org/guide/en/#watch-options).
### Debugging in VSCode
Add a file `.vscode/launch.json` with the following configuration:
```json
{
"version": "0.2.0",
"configurations": [
{
"name": "Debug Main Process",
"type": "node",
"request": "launch",
"cwd": "${workspaceRoot}",
"runtimeExecutable": "${workspaceRoot}/node_modules/.bin/electron-vite",
"windows": {
"runtimeExecutable": "${workspaceRoot}/node_modules/.bin/electron-vite.cmd"
},
"runtimeArgs": ["--sourcemap"]
}
]
}
```
Then, set some breakpoints in `main.ts` (source code), and start debugging in the `VSCode Debug View`.
### Source Code Protection
Use the plugin `bytecodePlugin` to enable it:
```js
import { defineConfig, bytecodePlugin } from 'electron-vite'
export default defineConfig({
main: {
plugins: [bytecodePlugin()]
},
preload: {
plugins: [bytecodePlugin()]
},
renderer: {
// ...
}
})
```
`bytecodePlugin` only works in production and supports the main process and preload scripts.
Also, you can learn more by playing with the [example](https://github.com/alex8088/electron-vite-bytecode-example).
### Getting Started
Clone the [electron-vite-boilerplate](https://github.com/alex8088/electron-vite-boilerplate) or use the [create-electron](https://github.com/alex8088/quick-start/tree/master/packages/create-electron) tool to scaffold your project.
```bash
npm create @quick-start/electron@latest
npm init @quick-start/electron
```
Currently supported template presets include:
