WebDev-如何讓現有的Astro.js專案使用deno

前置

Deno 從 1.39 版本開始，便持續提升與 Node.js 環境及 npm 套件的兼容性。

到了 2.0 版本，這種兼容性更是大幅度提升，使得許多原本專為 Node.js 開發的工具和函式庫，都能在 Deno 中無縫接軌。尤其這項重大改進，不僅讓網頁開發者能夠更輕鬆地將既有專案從 Node.js 遷移到 Deno，同時也降低了轉換過程中的複雜度。

因此想寫相關的教學文，方便自己後續維護時進行查看。

Announcing Deno 2

注意部分

本教學使用範例程式: neko0xff/blog_astroV2

開發時，各項工具&環境的版本
- 伺服端環境
  - Deno: 2.0.0
  - node: v21.6.2
- 套件依賴管理
  - npm: 10.8.0
  - npx: 10.8.0
- 函式庫
  - Astro.js: v4.16.2
  - @astrojs/react: ^3.6.1
當該專案是使用 Node (ex:npx,npm) 建立時, Deno 會優先將 npm 相依項目新增到 package.json 中,而不是使用 Deno 自己的相依性管理系統
在編譯完成後，若想預覽輸出結果或提供服務，則預設使用的通訊端口會是 ‘8085/tcp’

開始配置

在 Astro.js 專案內加入相關依賴

$ npx astro add deno
$ npm install @deno/astro-adapter

更新astro.config.ts配置檔

output部分請盡量使用hybird模式，否則某些需要開啟 prerender 預先渲染的組件或者套件無法成功運作(ex: @resvg/resvg-js)

 import { defineConfig } from 'astro/config';
 import deno from '@deno/astro-adapter';

 export default defineConfig({
   output: 'hybird',
   adapter: deno(),
 });

加入deno.json(方便後續使用 deno task 進行維護)

{
    "tasks": {
      "start": "deno run -A --unstable npm:astro dev",
      "dev": "deno run -A --unstable npm:astro dev",
      "preview": "deno run --allow-net --allow-read --allow-env ./dist/server/entry.mjs",
      "build": "astro build",
      "test": "deno test --allow-net",
      "lint": "deno lint"
    }
}

輸出可供以預覽使用的成果

編譯: $ deno task build
- 由於編譯過程過多，所以有做相關的刪減

執行編譯完成的結果

執行預覽: $ deno task preview

# user @ Host-02 in ~/文件/GitHub/blog_astroV2 on git:main o [10:26:57] 
$ deno task preview
Task preview deno run --allow-net --allow-read --allow-env ./dist/server/entry.mjs
Server running on port 8085

提供服務: $ deno task serve

$ deno task serve
Task serve deno serve --allow-net  --allow-read --allow-env ./dist/server/entry.mjs
Server running on port 8085
error: deno serve requires export default { fetch } in the main module, did you mean to run "deno run"?

建置成docker image

本範例會使用 Arch Linux 的 image 進行修改建置

先在專案目錄下建立Dockerfile.env

FROM archlinux:base-devel
WORKDIR /app

# 安裝相關套件
RUN pacman -Syyu --noconfirm\
 && pacman -S --noconfirm deno nodejs npm\
 && pacman -Scc --noconfirm

# 環境建置
COPY package*.json ./
RUN deno upgrade # 由於Arch套件庫還未更新(20241015),就直接使用官方更新
RUN npm install
COPY . .

# 編譯源碼
RUN deno task build
CMD ["deno", "task", "serve"]

# 指定通訊埠
EXPOSE 8085

再建立docker-compose.yml

services:
    weblog_deno:
      restart: always # 跟系統服務一起重啟
      ports:
        # 主機端口:容器端口
        - 8085:8085
      # 編譯時的設置
      build:
        context: .
        dockerfile: Dockerfile.env

開始建置: $docker compose up --build -d
