Cannot find module "." when running universal server

See original GitHub issue

When I followed the Angular Universal: server-side rendering tutorial to start the universal server, I met the error:

Error: Cannot find module "."
    at webpackMissingModule (/home/zhezhu/Documents/fm-frontend-jobs/dist/server.js:164237:82)

I tried to start it without webpack, then there would be another error with ngx-charts:

/home/zhezhu/Documents/fm-frontend-jobs/node_modules/@swimlane/ngx-charts/release/line-chart/line-series.component.js:10
import { Component, Input, ChangeDetectionStrategy } from '@angular/core';
       ^

    at Module.require (internal/modules/cjs/loader.js:626:17)
    at require (internal/modules/cjs/helpers.js:20:18)

and I don’t know why.

Thanks for your help.

@yanivamrami Yes as a matter of fact I did. The issue is with how ngx charts is packaged, currently node doesn’t support the current packaging. To fix this I installed Babbel as a dev dependency and added the following scripts to my package.json:

“compile_@swimlane_ngx-charts”: “babel node_modules/@swimlane/ngx-charts -d node_modules/@swimlane/ngx-charts --presets es2015”
“postinstall”: “npm run compile_@swimlane_ngx-charts”

So whenever I run npm install, ngx charts is automatically compiled into a compatible format. I have no issues runnning this with Angular 6.1.6, @nguniversal/express-engine 6.1.0 and @nguniversal/common 6.1.0.

Hope I was of help!
