Why is the NodeJS version on Kudu different from my App version?

I am getting the error below while deploying my NodeJS app on Azure:

node:internal/modules/cjs/loader 
Error: Cannot find module '...'

According to some research, it should be a node version issue. My App is supposed to run with the stack Node-18-lts, and I set the engines accordingly in my packages.json file, but when I bash into Kudu, I see node 14.

Why isn't it Node 18 ? I don't know if that will fix my issue, but at least, it seems to be an issue too.

Solution

  • The error you're encountering is not related to node versions.

    In the Bash section of Azure Web App, the default NodeJS version is v14.19.2

    When I checked the NodeJs version via SSH console it correctly gave Node 18.19.1 version.

    According to the error message you've provided, I added the line below to your package.json file, as described in this Document

    "scripts":  {  
"start":  "node node_modules/@strapi/strapi/bin/strapi.js start"  
}

    Below is the complete package.json file:

    Package.json:

    After deploying the app to Azure App Service, I added the following startup command in app configurations.

    pm2 serve /home/site/wwwroot/build --no-daemon --spa
