Hosted Node.js Server

Using HTTP access + cloud functions makes it easy to host Node.js server-side programs.

Preparations​

  1. Prepare a basic project directory. Refer to Quick Start - Initialize Directory

Creating a Simple Hello World​

In the working directory, execute the following commands to create the simplest Node.js Server:

mkdir functions/server && touch functions/server/index.js && touch functions/server/package.json

The content of functions/server/index.js` is as follows:

// functions/server/index.js
const serverless = require("serverless-http");

exports.main = serverless((req, res) => {
  res.statusCode = 200;
  res.setHeader("Content-Type", "text/plain");
  res.end("Hello World\n");
});
Tip

Here we use serverless-http to convert integration requests into IncomingMessage that can be received by a Node.js Server, while converting the returned ServerResponse into integration responses

The content of functions/server/package.json` is as follows:

{
  "name": "my-serverless-server",
  "version": "1.0.0",
  "main": "index.js",
  "dependencies": {
    "serverless-http": "^2.3.0"
  }
}

Publish​

Publish Cloud Function:

cloudbase fn deploy server

Create route:

cloudbase service create -p server -f server

Then you can access the Node.js Server via https://${env}.service.tcloudbase.com/server:

curl https://${env}.service.tcloudbase.com/server
Hello World
