How to enable production mode?

Question

You enable it by importing and executing the function (before calling bootstrap):

import {enableProdMode} from '@angular/core';

enableProdMode();
bootstrap(....);

But this error is indicator that something is wrong with your bindings, so you shouldn't just dismiss it, but try to figure out why it's happening.

The best way to enable the production mode for an Angular 2 application, is to use angular-cli and build the application with ng build --prod. This will build the application with production profile. Using angular-cli has the benefit of being able to use development mode using ng serve or ng build while developing without altering the code all the time.

This worked for me, using the latest release of Angular 2 (2.0.0-rc.1):

main.ts

import {enableProdMode} from '@angular/core';

enableProdMode();
bootstrap(....);

Here is the function reference from their docs: https://angular.io/api/core/enableProdMode

When I built a new project using angular-cli. A file was included called environment.ts. Inside this file is a variable like so.

export const environment = {
  production: true
};

Then in main.ts you have this.

import './polyfills.ts';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { environment } from './environments/environment';
import { AppModule } from './app/';

if (environment.production) {
  enableProdMode();
}

platformBrowserDynamic().bootstrapModule(AppModule);

You could add this to a non angular-cli project, I would assume, because enableProdMode() is being imported from @angular/core.

Go to src/enviroments/enviroments.ts and enable the production mode

export const environment = {
  production: true
};

for Angular 2

To enable production mode in angular 6.X.X Just go to environment file

Like this path

Your path: project>\src\environments\environment.ts

Change production: false from :

export const environment = {
  production: false
};

To

export const environment = {
  production: true
};
