How to add safely Angular Material to an existing angular application?

I'm trying to add Angular Material to my application. I installed Material components using this npm command

npm install --save @angular/material @angular/animations @angular/cdk

I had to update all my angular components to 7.0.2 version. I added a new material module and referenced it from my app.module.js

material.module.ts

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

import {
  MatButtonModule,
  MatMenuModule,
  MatToolbarModule,
  MatIconModule,
  MatCardModule
} from '@angular/material';

@NgModule({
  imports: [
    MatButtonModule,
    MatMenuModule,
    MatToolbarModule,
    MatIconModule,
    MatCardModule
  ],
  exports: [
    MatButtonModule,
    MatMenuModule,
    MatToolbarModule,
    MatIconModule,
    MatCardModule
  ]
})
export class MaterialModule {}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { HttpModule } from '@angular/http';
import { FormsModule } from '@angular/forms';

import { AppComponent } from "./app.component";
import { AppRoutingModule } from "./app-routing.module";

import { MaterialModule } from './material.module';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';



@NgModule({
    imports: [BrowserModule, AppRoutingModule, HttpModule, FormsModule, MaterialModule, BrowserAnimationsModule],
    declarations: [AppComponent],
    bootstrap: [AppComponent]

})
export class AppModule { }

Here is my package.json

    "protractor": "~4.0.14",
    "rimraf": "^2.5.4",
    "tslint": "^3.15.1"
  },
  "repository": {}
}

I cleaned node_modules and reinstalled everything to make I have all latest files. When I try to build my project I get all kind of errors. Mainly errors come from **\@angular\core** or **\@angular\common**

I spent too many hours and obviously I'm missing something because it shouldn't be so complicated.

What was the Angular version previously you used? You can follow this guide to upgrade. update.angular.io – wannadream

I can see two potential problems:

  1. The release of Angular Material 7 now requires RxJS 6.3. You should update your RxJS package to "rxjs": "~6.3.3". The syntax changed a bit, so have a look at this update guide.

  2. Have you included the base material theme file in your main .scss file as per this step?

Also, I don't think you meant to install the "angular-material": "^1.1.10", package. Its for Angular.js. You can remove it.

Install Angular Material

Use the Angular CLI's install schematic to set up your Angular Material project by running the following command:

ng add @angular/material

If need display MatSliderModule

You need to import the MatSliderModule that you want to display by adding the following lines to your app.module.ts file.

import { MatSliderModule } from '@angular/material/slider';

 @NgModule ({....
 imports: [...,
 MatSliderModule,
 …]
 })

Add the tag to the app.component.html like so:

Run your local dev server:

ng serve and point your browser to http://localhost:4200
