該nodejs應用的package.json：

{"name": "debug-cloud","version": "1.0.0","description": "","main": "index.js","engines": {"node": "12.X" },"scripts": {"start": "node --inspect index.js","test": "echo \"Error: no test specified\" && exit 1"},"author": "","license": "ISC","dependencies": {"express": "^4.17.1"} }

index.js:

const express = require('express') const app = express()app.get('/debug', function(req, res){ res.send("Debug endpoint called")});// Start server app.listen(process.env.PORT || 8080, ()=>{})

為了部署這個nodejs應用，需要一個Manifest.yml：

--- applications: - name: debug-appmemory: 128Mrandom-route: truebuildpacks:- nodejs_buildpack

使用命令行部署應用：

cf login #Perform you login to your cf account -- a demo account works as wellcf push #push your application

給CloudFoundry space啟用ssh支持：

cf enable-ssh <app-name> cf allow-space-ssh <space-name> cf restage <app-name>

重啟應用。

在Visual Studio Code里添加一個launch configuration：

{"type": "node","request": "attach","name": "Attach cloud app ","address": "localhost","port": 9229,"localRoot": "${workspaceFolder}","remoteRoot": "/home/vcap/app"}

將一個本地端口號綁定到nodejs應用上：

cf ssh <APP_NAME> -N -T -L 9229:127.0.0.1:9229

上述命令行將遠端服務器的9229端口綁定到本地計算機的9229端口。

現在就可以開始在本地Visual Studio Code里調試了：
