Hi Samuel,

I ended up performing yarn install on server to have the package installed on server.

Hi,
When we run node dist/server.js I am getting following error:

Error: Invalid provider for undefined. useClass cannot be undefined.
Usually it happens when:
1. There's a circular dependency (might be caused by using index.ts (barrel) files).
2. Class was used before it was declared. Use forwardRef in this case.
at syntaxError (C:\Users\nagaraajuk\Desktop\New folder\dist\node_modules@angular\compiler\bundles\compiler.umd.js:287:21)

Node Version: 9.11.0
Webpack version: 4.0.0
NPM version: 5.6.0

Please help us to resolve the above issue.

Thanks.

Hi All,

I got a fix for the above-mentioned issue.

I have added below lines in webpak.config.ts

"module": {
"rules": [
{
"enforce": "pre",
"test": /.js$/,
"loader": "source-map-loader",
"exclude": [
// instead of //node_modules//
path.join(process.cwd(), 'node_modules')
]
},

I have the same problem. The problem started when i was trying to fix another problem . My universal app kept failing during build but doing the following in webpack.server.config.js allowed the app to build. But cause the same problem you guys described above.

const nodeExternals = require('webpack-node-externals');

module.exports = {
...
   externals: [nodeExternals()],
...
}

Did you guys find a solution? are you still working on it?
