Alibaba Cloud Function Compute

Alibaba Cloud Function Compute is a fully managed, event-driven compute service. Function Compute allows you to focus on writing and uploading code without having to manage infrastructure such as servers.

1. Setup

serverless-devs is an open source and open serverless developer platform dedicated to providing developers with a powerful tool chain system. Through this platform, developers can not only experience multi cloud serverless products with one click and rapidly deploy serverless projects, but also manage projects in the whole life cycle of serverless applications, and combine serverless devs with other tools / platforms very simply and quickly to further improve the efficiency of R & D, operation and maintenance.

Install serverless-devs CLI

npm install @serverless-devs/s -g

Add the AK & SK configuration

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

2. Hello World

Create a new project in a new directory:

npm init

Add the required dependencies:

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

Edit scripts section in package.json:

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

Edit 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,
})

Edit tsconfig.json

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