【ES Modules】Cloud Functionsでrequire()ではなくimportを使う【index.mjs】

type: moduleを使う場合

package.json

{
  "name": "sample-http",
  "type": "module",
  "version": "0.0.1"
}

index.js

/**
 * Responds to any HTTP request.
 *
 * @param {!express:Request} req HTTP request context.
 * @param {!express:Response} res HTTP response context.
 */
export const helloWorld = (req, res) => {
  let message = req.query.message || req.body.message || 'Hello World!'
  res.status(200).send(message)
}

index.mjsを使う場合

コンソールエディタでシンタックスハイライトがきかないので、あまりオススメはしません

package.json

{
  "name": "sample-http",
  "main": "index.mjs",
  "version": "0.0.1"
}

index.mjs

/**
 * Responds to any HTTP request.
 *
 * @param {!express:Request} req HTTP request context.
 * @param {!express:Response} res HTTP response context.
 */
export const helloWorld = (req, res) => {
  let message = req.query.message || req.body.message || 'Hello World!'
  res.status(200).send(message)
}

Puppeteerを使った例

Node.js 16を選択し、メモリを2GB以上にしましょう

package.json

{
  "name": "sample-http",
  "main": "index.mjs",
  "version": "0.0.1",
  "dependencies": {
    "puppeteer": "^19.7.5"
  }
}

index.mjs

import puppeteer from 'puppeteer'

/**
 * Responds to any HTTP request.
 *
 * @param {!express:Request} req HTTP request context.
 * @param {!express:Response} res HTTP response context.
 */
export const helloWorld = async (req, res) => {
  await puppeteer.createBrowserFetcher().download(puppeteer.defaultBrowserRevision)
  const browser = await puppeteer.launch()
  const page = await browser.newPage()
  await page.goto('https://example.com/')
  res.send(await page.content())
  await browser.close()
}
