在Express中包装的Azure NextJs应用程序上部署后，应用程序将永远加载

Question

Hi I am trying to deploy nextjs app using devOps project with server.js which looks like that:

 const express = require('express') const next = require('next') const dev = process.env.NODE_ENV !== 'production' const app = next({ dev }) const handle = app.getRequestHandler() app.prepare() .then(() => { var port = process.env.port || 3001 const server = express() server.get('*', (req, res) => { return handle(req, res) }) server.listen(port, (err) => { if (err) throw err console.log('> Ready on http://localhost:433') }) }) .catch((ex) => { console.error(ex.stack) process.exit(1) }) 

For devOPs project I set up github, vsts and then it goes off to azure.

I used the default set up for nodejs, only what I did additionaly in VSTS pipelines I added npm script "npm run build".

My agent job in buld looks like this:

• -User node version
• -Npm install application dependencies
• -Npm custom (Added by me, run build)
• -Archive Files
• -Public Artifact drop.

And in release:

• Azure Deployment: Create Azure App
• Deploy Azure App Service

The problem is that Build succedes same as release, but then when I try to access the website it loads forever. I did my research but found nothing.

I have been trying to make it work for 3 days now... Please help

Yesterday I successfully deployed NextJs App to Azure App service by using Azure Devops build and release pipelines.

Below are three issues I faced. I am also sharing solution screenshots for each issue.

1. Azure App service Node version should be compatible with your nextjs.

2. Missing web.config file at root

3. Incorrect port number in server.js and incorrect script tags in package.json

My build pipeline looks similar like you. https://i.imgur.com/0Y8m2wH.png
