如何将Express部署到Firebase? [英] How to deploy express to Firebase?

问题描述

目前，我正在学习Express和Firebase.我可以向Firebase部署角度页面或React页面(前端).

Currently i'm learning express and Firebase. I can deploy an angular or react page (front-end) to Firebase.

现在，我正在尝试使用express创建后端，然后我意识到，我不能简单地将其作为另一个项目部署到Firebase，因为Firebase托管将寻找index.html作为入口点(*请正确我，如果我错了).我已经尝试过Firebase函数，但仍然不能.

And now, i'm trying to create the back-end using express, then i realize, i cant just simply deploying it as another project to Firebase since Firebase hosting will looking for index.html as entry point (*please correct me if i'm wrong). I've tried Firebase functions but still can't.

我可以将javascript(expressjs)文件设置为Firebase作为入口点吗?

Can i set a javascript (expressjs) file to Firebase as entry point?

谢谢.

推荐答案

您可以将Express应用程序部署到 Firebase Cloud Functions 作为 HTTP触发器.有一个示例对此进行了说明.实现的基本形式在您的Cloud Functions index.js中如下所示:

You can deploy an Express app to Cloud Functions for Firebase as an HTTP trigger. There is a sample that illustrates this. The basic form of implementation looks like this in your Cloud Functions index.js:

const functions = require('firebase-functions')
const express = require('express')
const app = express()
// configure app here, add routes, whatever
exports.api = functions.https.onRequest(app)

现在，您可以在路径https://您的分配的主机名/api/whatever下访问路由

编辑

如果要将每个请求重定向到Express应用，还需要配置 firebase.json 文件.

You also need to configure your firebase.json file if you want to redirect every request to the Express app.

将此行添加到 hosting 对象内:"rewrites" : [{"source" : "**", "function" : "api"}]

Add this line inside the hosting object: "rewrites" : [{"source" : "**", "function" : "api"}]
