Current behavior

If I add the GridModule then do 'ng build --prod' I get.
ERROR in main.xxx.bundle.js from UglifyJs
TypeError: str.replace is not a function

Minimal reproduction of the problem with instructions

1. Download the latest Angular-Cli (v1.6.4)
2. Create a new angular cli project using 'ng new my-grid'
3. 'cd my-grid'
4. Download and install kendo grid package

npm install --save @progress/kendo-angular-grid @progress/kendo-angular-dropdowns @progress/kendo-angular-inputs @progress/kendo-angular-dateinputs @progress/kendo-data-query @progress/kendo-angular-intl @progress/kendo-angular-l10n @progress/kendo-drawing @progress/kendo-angular-excel-export @angular/animations

5. import GridModule in your application root module

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { GridModule } from '@progress/kendo-angular-grid';
import { AppComponent } from './app.component';

@NgModule({
   bootstrap:    [AppComponent],
   declarations: [AppComponent],
   imports:      [BrowserModule, BrowserAnimationsModule, GridModule]
})
export class AppModule {
}

6. run 'ng build --prod'

You get a build error.
ERROR in main.xxxxxx.bundle.js from UglifyJs
TypeError: str.replace is not a function

BTW 'ng build --prod' works fine if you remove GridModule from app.module.ts

It seems like a @angular/cli uglify-es npm package issue. angular/angular-cli#9218
Pinning "uglify-es" to "3.3.5" fixes the issue.

[billdwhite]

I've got mine locked to 3.3.5 and I'm still getting this for the grid component

[rvrn22]

I had to delete my node_modules folder and package-lock.json and then npm install again to get the correct dependencies.

[wmgdev]

Yay, Thanks all.
Just to confirm I had to do all of the following to get this to work.

1. Add "uglify-es": "3.3.5", to devDependancies in package.json
2. Delete node_modules folder
3. delete package-lock.json file
4. npm install

ng build --prod then worked.

This is probably a Angular-cli / Uglify issue rather than Kendo Grid... but Kendo GridModule was the only module in my package.json that made it surface.
Thanks again

We have applied a workaround for the error in the package for which it was thrown - telerik/kendo-intl. Updating the package should also resolve the problem.

@danielkaradachki I see this same error issue using @progress packages. Is there an update for those as well?

[danielkaradachki]

Which packages? The error would be thrown for packages that have dependency to progress/kendo-angular-intl which has dependency to telerik/kendo-intl.

[acohenOT]

Never mind. I updated all my packages again and now ng build is working properly.
