英文:
Module not found 'express' when deploying to azure app service
问题
以下是您提供的内容的翻译：
我有一个名为 server.js 的节点文件，我可以在本地成功运行它，它的代码如下：
const express = require('express')
const compression = require('compression')
const path = require('path')
const { renderPage } = require('vite-plugin-ssr/server')
const isProduction = process.env.NODE_ENV === 'production'
const root = path.resolve(__dirname, '..')
const clientPath = path.join(root, 'client')
async function startServer() {
const app = express()
app.use(compression())
if (isProduction) {
const sirv = require('sirv')
app.use(sirv(clientPath))
} else {
const vite = require('vite')
const viteDevMiddleware = (
await vite.createServer({
root,
server: { middlewareMode: true },
})
).middlewares
app.use(viteDevMiddleware)
}
// eslint-disable-next-line consistent-return
app.get('*', async (req, res, next) => {
const pageContextInit = {
urlOriginal: req.originalUrl,
}
const pageContext = await renderPage(pageContextInit)
const { httpResponse } = pageContext
if (!httpResponse) return next()
const {
body, statusCode, contentType, earlyHints,
} = httpResponse
if (res.writeEarlyHints) res.writeEarlyHints({ link: earlyHints.map((e) => e.earlyHintLink) })
res.status(statusCode).type(contentType).send(body)
})
const port = process.env.PORT || 5173
app.listen(port)
console.log(`Server running at http://localhost:${port}`)
}
startServer()
我还可以在运行 npm run build 后从我的 dist 文件夹中提供服务，没有任何问题。但是，一旦我将其部署到 Azure 的应用服务并尝试在那里运行它，我就会遇到错误。这是我的应用服务启动命令：
pm2 start js/server.js --no-daemon
我的流水线看起来像这样：
name: Azure dev deployment
on:
push:
branches:
- main
env:
AZURE_WEBAPP_NAME: {name}
AZURE_WEBAPP_PACKAGE_PATH: './dist'
NODE_VERSION: '16.x'
jobs:
build-and-deploy:
runs-on: ubuntu-latest
container: node:16
steps:
- uses: actions/checkout@v2
- name: set script to remove husky in CI
run: npm set-script prepare ''
- name: Dependency installation
run: npm ci
- name: linter
run: npm run lint
- name: build
env:
DISABLE_ESLINT_PLUGIN: true
run: npm run build --if-present
- name: tests
env:
DISABLE_ESLINT_PLUGIN: true
run: npm test
- name: 'Deploy to Azure WebApp'
uses: azure/webapps-deploy@v2
with:
app-name: ${{ appName }}
publish-profile: ${{ publishProfile }}
在我的部署包中是否应包含 node_modules 和/或 package.json？我有点迷失方向，正在猜测为什么会出现此错误，我会感激任何帮助。
谢谢！

I have a node server.js file which i can run just fine locally, and it looks like this:
const express = require('express')
const compression = require('compression')
const path = require('path')
const { renderPage } = require('vite-plugin-ssr/server')
const isProduction = process.env.NODE_ENV === 'production'
const root = path.resolve(__dirname, '..')
const clientPath = path.join(root, 'client')
async function startServer() {
const app = express()
app.use(compression())
if (isProduction) {
const sirv = require('sirv')
app.use(sirv(clientPath))
} else {
const vite = require('vite')
const viteDevMiddleware = (
await vite.createServer({
root,
server: { middlewareMode: true },
})
).middlewares
app.use(viteDevMiddleware)
}
// eslint-disable-next-line consistent-return
app.get('*', async (req, res, next) => {
const pageContextInit = {
urlOriginal: req.originalUrl,
}
const pageContext = await renderPage(pageContextInit)
const { httpResponse } = pageContext
if (!httpResponse) return next()
const {
body, statusCode, contentType, earlyHints,
} = httpResponse
if (res.writeEarlyHints) res.writeEarlyHints({ link: earlyHints.map((e) => e.earlyHintLink) })
res.status(statusCode).type(contentType).send(body)
})
const port = process.env.PORT || 5173
app.listen(port)
console.log(`Server running at http://localhost:${port}`)
}
startServer()
I can also serve it from my dist folder after running npm run build without any issues. But as soon as i deploy it to my app service in azure and try to run it there i get the error. Here is my app service startup command:
pm2 start js/server.js --no-daemon
My pipeline looks like this:
name: Azure dev deployment
on:
push:
branches:
- main
env:
AZURE_WEBAPP_NAME: {name}
AZURE_WEBAPP_PACKAGE_PATH: './dist'
NODE_VERSION: '16.x'
jobs:
build-and-deploy:
runs-on: ubuntu-latest
container: node:16
steps:
- uses: actions/checkout@v2
- name: set script to remove husky in CI
run: npm set-script prepare ''
- name: Dependency installation
run: npm ci
- name: linter
run: npm run lint

run: npm run build --if-present

env:
DISABLE_ESLINT_PLUGIN: true
run: npm test
- name: 'Deploy to Azure WebApp'
uses: azure/webapps-deploy@v2
with:
app-name: ${{ appName }}
publish-profile: ${{ publishProfile }}
Should node_modules and/or package.json be included in my deployment package to my app service? I'm a bit lost here and trying to speculate as to why I'm getting this error and would appreciate any help.
Thanks

确保在运行 GitHub Action 工作流的 GitHub 仓库的节点模块中包含 express.js：
**我的 GitHub 仓库包含 Express.js 应用程序：**
**我的 package.json：**
```json
{
"name": "myexpressapp7",
"version": "0.0.0",
"private": true,
"scripts": {
"start": "node ./bin/www"
},
"dependencies": {
"cookie-parser": "~1.4.4",
"debug": "~2.6.9",
"ejs": "~2.6.1",
"express": "~4.16.1",
"http-errors": "~1.6.3",
"morgan": "~1.9.1",
"pm2": "^5.3.0"
}
}
节点模块文件夹中包含 express 包：
我的 GitHub 工作流：
name: 构建并部署 Node.js 应用程序到 Azure Web App - valleywebapp984
on:
push:
branches:
- master
workflow_dispatch:
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2

uses: actions/setup-node@v1

node-version: '18.x'
- name: npm 安装，构建和测试

npm install
npm run build --if-present
npm run test --if-present

package: .
输出：
为了运行 pm2 服务器，请参考我的 Stack Overflow 帖子回答 此处。
将此作为 Web 应用程序的启动命令添加到 Web 应用程序中，重新加载您的 Web 应用程序并像下面这样检查日志流：
启动命令：
pm2 start ./bin/www
英文:
Make sure the express.js is included in the node modules in your github repository where you're running the github action workflow:-
My github repository with Express.js app:-
My package.json:-
{
"name": "myexpressapp7",
"version": "0.0.0",
"private": true,
"scripts": {
"start": "node ./bin/www"
},
"dependencies": {
"cookie-parser": "~1.4.4",
"debug": "~2.6.9",
"ejs": "~2.6.1",
"express": "~4.16.1",
"http-errors": "~1.6.3",
"morgan": "~1.9.1",
"pm2": "^5.3.0"
}
}
node modules folder contains express package:-
My github workflow:-
name: Build and deploy Node.js app to Azure Web App - valleywebapp984
on:
push:
branches:
- master
workflow_dispatch:
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Set up Node.js version
uses: actions/setup-node@v1
with:
node-version: '18.x'
- name: npm install, build, and test
run: |
npm install
npm run build --if-present
npm run test --if-present
- name: Upload artifact for deployment job
uses: actions/upload-artifact@v2
with:
name: node-app
path: .
deploy:
runs-on: ubuntu-latest
needs: build
environment:
name: 'production'
url: ${{ steps.deploy-to-webapp.outputs.webapp-url }}
steps:
- name: Download artifact from build job
uses: actions/download-artifact@v2
with:
name: node-app
- name: 'Deploy to Azure Web App'
id: deploy-to-webapp
uses: azure/webapps-deploy@v2

app-name: 'valleywebapp984'
slot-name: 'production'
publish-profile: ${{ secrets.AzureAppService_PublishProfile_2eccd9239cc34b3990c26fadf7c6ae60 }}
package: .
Output:-
In order to run the pm2 server, Refer my SO thread answer here
Add this as a start up command in the Web app, reload your web app and check the Log stream like below:-
Start up command:-
pm2 start ./bin/www
