Answer 1

I am using Angular 7

I have to import ReactiveFormsModule because I am using FormBuilder class to create reactive form.

import { 
FormsModule, 
ReactiveFormsModule } from '@angular/forms';

@NgModule({
  imports: [
    CommonModule,
    FormsModule,
    ReactiveFormsModule
  ], declarations: []})

Answer 2

This is for the folks who use plain JavaScript instead of Type Script. In addition to referencing the forms script file on top of the page like below

<script src="node_modules/@angular/forms/bundles/forms.umd.js"></script>

you should also tell the the module loader to load the ng.forms.FormsModule. After making the changes my imports property of NgModule method looked like below

imports: [ng.platformBrowser.BrowserModule, ng.forms.FormsModule],

Happy coding!

In ngModule you need to import FormsModule, because ngModel is coming from FormsModule. Please modify your app.module.ts like the below code I have shared

import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

@NgModule({
    declarations: [
         AppComponent,
         HomeComponent
    ],
    imports: [
         BrowserModule,
         AppRoutingModule,
         FormsModule
    ],
    bootstrap: [AppComponent]
})
export class AppModule { }

Answer 4

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';

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

Answer 5

Sometimes you get this error when you try to use a component from a module, which is not shared, in a different module.

For example, you have 2 modules with module1.componentA.component.ts and module2.componentC.component.ts and you try to use the selector from module1.componentA.component.ts in a template inside module2 (e.g. <module1-componentA [someInputVariableInModule1]="variableFromHTTPRequestInModule2">), it will throw the error that the someInputVariableInModule1 is not available inside module1.componentA.component.ts - even though you have the @Input() someInputVariableInModule1 in the module1.componentA.

If this happens, you want to share the module1.componentA to be accessible in other modules. So if you share the module1.componentA inside a sharedModule, the module1.componentA will be usable inside other modules (outside from module1), and every module importing the sharedModule will be able to access the selector in their templates injecting the @Input() declared variable.

Answer 6

You need to import FormsModule in your root module if this component is in the root i.e. app.module.ts

Kindly open app.module.ts

Import FormsModule from @angular/forms

Ex:

import { FormsModule } from '@angular/forms';

and

@NgModule({
imports: [
   FormsModule
],
})
