阿里云函数计算

阿里云函数计算 是一种完全托管的事件驱动型计算服务。函数计算使您能够专注于编写和上传代码，而无需管理服务器等基础设施。

1. 设置

serverless-devs 是一个开源的开放式无服务器开发者平台，致力于为开发者提供强大的工具链系统。通过该平台，开发者不仅可以一键体验多云无服务器产品，快速部署无服务器项目，还可以管理无服务器应用程序整个生命周期中的项目，并将无服务器开发人员与其他工具/平台非常简单快捷地结合起来，进一步提高研发、运维的效率。

安装 serverless-devs CLI

npm install @serverless-devs/s -g

添加 AK & SK 配置

s config add
# Please select a provider: Alibaba Cloud (alibaba)
# Input your AccessKeyID & AccessKeySecret

2. Hello World

在新的目录中创建一个新项目

npm init

添加所需的依赖项

npm add hono @hono/node-server
npm add esbuild --save-dev

编辑 package.json 中的 scripts 部分

{
  "scripts": {
    "build": "esbuild --bundle --outfile=./dist/index.js --platform=node --target=node20 ./src/index.ts",
    "dev": "node ./dist/index.js",
    "deploy": "s deploy -y"
  }
}

编辑 src/index.ts

import { serve } from '@hono/node-server'
import { Hono } from 'hono'

const REQUEST_ID_HEADER = 'x-fc-request-id'

const app = new Hono()

app.post('/initialize', (c) => {
  console.log(`RequestId: ${c.req.header(REQUEST_ID_HEADER)}`)
  return c.text('Initialize')
})

app.post('/invoke', (c) => {
  console.log(`RequestId: ${c.req.header(REQUEST_ID_HEADER)}`)
  return c.text('Invoke')
})

app.get('/', (c) => {
  return c.text('Hello from index!')
})

app.get('/hello', (c) => {
  return c.text('Hi!')
})

const port = 9000
console.log(`Server is running on port ${port}`)

serve({
  fetch: app.fetch,
  port,
})

编辑 tsconfig.json

{
  "compilerOptions": {
    "target": "ESNext",
    "module": "ESNext",
    "moduleResolution": "Bundler",
    "strict": true,
    "skipLibCheck": true,
    "lib": ["ESNext"],
    "types": [],
    "jsx": "react-jsx",
    "jsxImportSource": "hono/jsx"
  }
}

编辑 s.yaml

  region: 'us-west-1'

resources:
  my_app:
    component: fc3

3. 部署

最后，运行命令进行部署

npm install # install dependencies
npm run build # Compile the TypeScript code to JavaScript
npm run deploy # Deploy the function to Alibaba Cloud Function Compute
