声明单独的Firebase云函数并仍然使用Express.js

Question

使用Express进行Firebase云功能的例子很多。

在我发现的每一个示例中，代码都将Express应用程序公开为单个云功能：

exports.app = functions.https.onRequest(app);

对于Firebase项目函数，这意味着他们将看到一个名为“app”的条目，所有Express.js HTTP侦听器的所有日志都将放在Firebase中的一个位置。这也意味着，无论一个人的express.js应用程序有多大，Firebase都将为该应用程序在生产中部署单个功能。

export const hello = functions.https.onRequest(async (req, res) => {
  res.status(200).send('hello world');
});

感谢道格史蒂文森的回答和帮助。不过，我想提供我自己的答案。

所以我的问题的答案是，一般来说：不，你不能。

正如Doug所指出的，对于许多人的缩放需求来说，这并不是一个问题。Firebase将为您的函数创建多达1000个实例以进行扩展。

const payment = express()
const order = express()
payment.get('/route', ...)
order.get('/route', ...)
export const payment = functions.https.onRequest(payment)
export const order = functions.https.onRequest(order)

app.get('/user', async (req, res) => {
  await handleGetUser(req, res, paymentServiceLive);
});

app.post('/claim', async (req, res) => {
  await handleClaim(req, res, claimEmailTo);
