Angular 17 new builder can't run server.mjs

I updated my projecto Angular 17.1 and now when i try ng build it creates a server.mjs file in /dist//server directory which is meant to be served for production. when I try to run the file with node or pm2 i get the following error

TypeError: Nl is not a function

Node.js v20.11.0

Any Idea about how I can fix this ?

Solution

  • Setting optimization flag to false helped me find out that the problem was importing import express from 'express'; in server.ts file, This package needs setting this flag "allowSyntheticDefaultImports": true in angularCompilerOptions of tsconfing.json in Angular 17.
