使用 SvelteKit 和 Bun 構建應用

在 GitHub 上編輯

使用 sv create my-app 命令使用 SvelteKit CLI 建立一個 SvelteKit 專案。回答提示以選擇模板並設定您的開發環境。

bunx sv create my-app

專案初始化後，進入新專案目錄。您無需執行 'bun install'，因為依賴項已自動安裝。

然後使用 bun --bun run dev 啟動開發伺服器。

如果您想使用 Node.js 而不是 Bun 來執行開發伺服器，可以省略 --bun 標誌。

cd my-app
bun --bun run dev
  $ vite dev
  Forced re-optimization of dependencies

    VITE v5.4.10  ready in 424 ms

    ➜  Local:   https://:5173/
    ➜  Network: use --host to expose
    ➜  press h + enter to show help

在瀏覽器中訪問 https://:5173 檢視模板應用。

如果您編輯並儲存 src/routes/+page.svelte，您應該會在瀏覽器中看到您的更改被熱過載。

要構建生產版本，您需要新增正確的 SvelteKit 介面卡。目前我們推薦

bun add -D svelte-adapter-bun.

現在，對您的 svelte.config.js 進行以下更改。

import adapter from "@sveltejs/adapter-auto";
import adapter from "svelte-adapter-bun";
import { vitePreprocess } from '@sveltejs/vite-plugin-svelte';

/** @type {import('@sveltejs/kit').Config} */
const config = {
	// Consult https://svelte.dev/docs/kit/integrations#preprocessors
	// for more information about preprocessors
	preprocess: vitePreprocess(),

	kit: {
		// adapter-auto only supports some environments, see https://svelte.dev/docs/kit/adapter-auto for a list.
		// If your environment is not supported, or you settled on a specific environment, switch out the adapter.
		// See https://svelte.dev/docs/kit/adapters for more information about adapters.
		adapter: adapter()
	}
};

export default config;

構建生產 bundle

bun --bun run build
  $ vite build
  vite v5.4.10 building SSR bundle for production...
  "confetti" is imported from external module "@neoconfetti/svelte" but never used in "src/routes/sverdle/+page.svelte".
  ✓ 130 modules transformed.
  vite v5.4.10 building for production...
  ✓ 148 modules transformed.
  ...
  ✓ built in 231ms
  ...
  ✓ built in 899ms

  Run npm run preview to preview your production build locally.

  > Using svelte-adapter-bun
    ✔ Start server with: bun ./build/index.js
    ✔ done
