Directory structure of SOULs Nodejs runtime Cloud Functions

apps
├── cf_nodejs16_method1
│   ├── index.js
│   ├── package.json
│   ├── .env.yaml

Define the main function in index.js .

Here, Express.js routing is specified by the endpoint, so

You can have multiple endpoints.

index.js

const express = require('express');
const bodyParser = require('body-parser');

const app = express();
app.use(bodyParser.urlencoded({ extended: true }));

app.get('/souls-functions-get', (req, res)=>{
  res.json(req.query)
});

app.get('/souls-functions-get/:id', (req, res)=>{
  res.json(req.params)
});

app.post('/souls-functions-post', (req, res)=>{
  res.json(req.body)
});
exports.cf_nodejs16_task = app;
