環境構築

SveletKitを使ってCloudflare Workersにデプロイしてみる

Svelteの初期化

TyepScript
ESLint, Prettierを有効化

$ npm create svelte@latest svelte_starter
$ cd svelte_starter
$ yarn dev -- --open

Cloudflare Workers Adapterの追加

adapterのインストール

$ yarn add -D @sveltejs/adapter-cloudflare-workers

svelte.config.js の書き換え

import adapter from '@sveltejs/adapter-cloudflare-workers';
import preprocess from 'svelte-preprocess';

/** @type {import('@sveltejs/kit').Config} */
const config = {
	// Consult https://github.com/sveltejs/svelte-preprocess
	// for more information about preprocessors
	preprocess: preprocess(),

	kit: {
		adapter: adapter()
	}
};

export default config;

app.d.ts の書き換え

declare namespace App {
	// interface Locals {}
	interface Platform {
    env: {
      COUNTER: DurableObjectNamespace;
    };
    context: {
      waitUntil(promise: Promise<any>): void;
    };
    caches: CacheStorage & { default: Cache };
  }
	// interface PrivateEnv {}
	// interface PublicEnv {}
}

Cloudflare Workersへのデプロイ

wrangler.toml の作成

name = "<your-service-name>"
account_id = "<your-account-id>"

main = "./.cloudflare/worker.js"
site.bucket = "./.cloudflare/public"

build.command = "npm run build"

compatibility_date = "2021-11-12"
workers_dev = true

wrangler CLIの初期化

$ npm i -g wrangler
$ wrangler login

デプロイ

$ wrangler publish

UI開発

ライブラリ

ライブラリはTailwindを利用したことがないので、TailwindベースのSveleteライブラリを利用する

設定

ライブラリの設定を組み込む

app.postcss

/* Write your global styles here, in PostCSS syntax */
@tailwind base;
@tailwind components;
@tailwind utilities;

body { @apply bg-surface-100 dark:bg-surface-900 text-black dark:text-white p-4; }

layout.svelte

<script>
	import '../app.postcss';
  import '../theme.postcss';
</script>

<slot />

フォームは @tailwind/form を利用する
app.postcss に設定を追加
