In angular 2 I use

ng g c componentname

But It is not supported in Angular 4, so I created it manually, but it shows error that it is not a module.

    you need to import the manually created component in module.ts file Commented Jul 7, 2017 at 7:41
  • In Angular 7 also it works . ng g c <componentname> OR ng generate component <Name> Commented Apr 18, 2019 at 5:50
  • you can add component based on it's schematics and options according to documentation Commented Mar 12, 2020 at 9:24

This still works the same in Angular 4+. If you get an error, I think your problem is somewhere else.

In command prompt type:

ng generate component YOURCOMPONENTNAME

There are even shorthands for this: the commands generate can be used as g and component as c:

ng g c YOURCOMPONENTNAME

Of course, rename YOURCOMPONENTNAME to the name you would like to use.

You can use ng --help, ng g --help or ng g c --help for help, or visit https://angular.dev/cli/generate/component.

I am getting this error-----------installing component Error locating module for declaration SilentError: No module files found
I am wondering, is there any command available to remove created component including it's reference app module?
@pankysharma No there is no command in Angular CLI to remove a component, but if you want to recreate the component with different options; you can use the --force (shorthand: -f) option to override files.
"ng g c employees" worked for me. I was using a '$' before 'ng' like '$ng g c employees' which was creating issue in this case.
If you don't need the test file(.spec.ts) for your new component, add argument --skipTests to your command.

Generating and serving an Angular project via a development server -

First go to your Project Directory and the type the below -

ng new my-app
cd my-app

Here “D:\Angular\my-app>” is my Angular application Project Directory and the “User” is the name of component.

The commonds looks like -

D:\Angular\my-app>ng g component User
  create src/app/user/user.component.html (23 bytes)
  create src/app/user/user.component.spec.ts (614 bytes)

ng g component componentname

It generates the component and adds the component to module declarations.

when creating component manually , you should add the component in declaration of the module like this :

@NgModule({
  imports: [
    yourCommaSeparatedModules
    ],
  declarations: [
    yourCommaSeparatedComponents
  ]
})
export class yourModule { }

For creating component under certain folder

ng g c employee/create-employee --skipTests=false --flat=true

This line will create a folder name 'employee', underneath that it creates a 'create-employee' component.

without creating any folder

ng g c create-employee --skipTests=false --flat=true

Go to your project directory in CMD, run the following code.

ng g c componentname

A folder will be created in the component name. inside that, you can find four files such as HTML, CSS, spec.ts & ts.

And you should not rename any of the files.

You should be in the src/app folder of your angular-cli project on command line. For example:

D:\angular2-cli\first-app\src\app> ng generate component test

Only then it will generate your component.

component_name/component_name.component.html component_name/component_name.component.spec.ts component_name/component_name.component.ts component_name/component_name.component.css

new component will be Automatically added module.

Did you update the angular-cli to latest version? or did you try updating node or npm or typescript? this issue comes because of versions like angular/typescript/node. If you are updating the cli, use this link here. https://github.com/angular/angular-cli/wiki/stories-1.0-update

go to your angular project folder and open the command promt an type "ng g component header" where header is the new component that you want to create.As default the header component will be created inside the app component.You can create components inside a component .For example if you want to create a component inside he header that we made above then type"ng g component header/menu". This will create a menu component inside the header component

Step1:

Get into Project Directory!(cd into created app).

Step2:

Type in the following command and run!

ng generate component [componentname]

  • Add the name of component you want to generate in the [componentname] section.

OR

ng generate c [componentname]

  • Add name of component you want to generate in the [componentname] section.

Both will work

For reference checkout this section of Angular Documentation!

For reference also checkout the link to Angular Cli on github!

There are mainly two ways to generate new component in Angular, using ng g c <component_name> , another way is that using ng generate component <component_name>. using one of these commands new component can be generated.

cd to your project and run,

> ng generate component "componentname"
ex: ng generate component shopping-cart

OR

> ng g c shopping-cart

(This will create new folder under "app" folder with name "shopping-cart" and create .html,.ts, .css. specs files.)

If you do not want to generate .spec file

> ng g c shopping-cart --skipTests true

If you want to create component in any specific folder under "app"

> ng g c ecommerce/shopping-cart

(you will get folder structure "app/ecommerce/shopping-cart")

I think you have to upgrade the latest angular cli using this command.

npm install -g @angular/cli

Then if you run ng g c componentName, it will work.
