Create component & add it to a specific module with Angular-CLI

I'm starting to use angular-cli and I've already read a lot to find an answer about what I want to do...no success, so I came here.

Is there a way to create a component to a new module?

e.g.: ng g module newModule

ng g component newComponent (how to add this component to newModule??)

because the angular-cli default behavior is to put all new components inside app.module. I would like to choose where my component will be, so that I can create separated modules and won't have all my components inside app.module . It is possible to do that using angular-cli or do I have to do this manually?

To create a component as part of a module you should

ng g module newModule to generate a module, cd newModule to change directory into the newModule folder ng g component newComponent to create a component as a child of the module.

UPDATE: Angular 9

Now it doesn't matter what folder you are in when generating the component.

ng g module NewModule to generate a module. ng g component new-module/new-component to create NewComponent.

Note: When the Angular CLI sees new-module/new-component, it understands and translates the case to match new-module -> NewModule and new-component -> NewComponent. It can get confusing in the beginning, so easy way is to match the names in #2 with the folder names for the module and component.


You can also stay in the project root and prefix the component with the module name ng g component moduleName/componentName.
With Angular CLI version 1.6.8, I was always getting error sying that 'specified module doesn't exists', when I sepcify an existing module. It worked when I tried the following command: ng generate service service1 --module=module1/module1.module.ts. Note: my service name is service1 and my module name is module1
This would create a new component in the specified directory but wouldn't register it in the module. It will register it in the app.module. you would need to specify the module with the --module option like: ng g component <your component> --module=<your module name>
outdated as of 6th Oct, Angular 6
Outdated. Angular 6 does not depend on folder structures to see which module the component is in. Two modules can be in the same directory. @daniel's answer stackoverflow.com/a/44812014/511719 works for Angular 6.

ng g component nameComponent --module=app.module.ts

the other answers work, but this is the most efficient. Its worth adding --dry-run to the end of that just to see what will be affected, it's a nice sanity check
ng g component path/to/myComponent --module=app.module.ts --dry-run is a very useful command; just to make sure your component is created in the correct directory.
You can use a relative path in the module option, as follows ng g component componentName --module=../../sibling/path/custom.module.ts --dry-run
ng g c newComponent --module app works as well. I used this in the terminal while not in the same directory as the app.module.ts file and it put it in the correct module

Not sure if maybe Alexander Ciesielski's answer was correct at the time of writing, but I can verify that this no longer works. It doesn't matter which directory in the project you run the Angular CLI. If you type

ng g component newComponent

it will generate a component and import it into the app.module.ts file

The only way you can use CLI to automatically import it into another module is by specifying

ng g component moduleName/newComponent

where moduleName is a module you've already defined in your project. If the moduleName doesn't exist, it'll put the component in moduleName/newComponent directory but still import it into app.module


it was the right answer for me at the time..it works properly. I create a pull request to add this information to the docs. One of it's contributors ask me to remove cd-ing part..in the end will be 1. ng g module newModule 2. ng g component new-module/newComponent according to him should be new-module instead of newModule
Just to point out, using technique by Alexander Ciesielski and works as expected. I should note, I did not need to create component simply needed to create folder. So I just mkdir a folder, and then ran n g component newComponent inside of newly created folder.
I would say that full answer is ng g component moduleName/newComponent -m moduleName
In my case the component name is same as the module name so I created the module with ng generate module {modComName} 1) Created the folder 2) Created a module file inside the folder of same name ; the command ng generate component {modComName} actually 1) Created a component file inside the folder of same name 2) Modified the module to import the component
Be careful if you create a module and import it into a base module; ng adds imports to the end of the array; but you may want : "The order of the routes in the configuration matters and this is by design."

I didn't find an answer that showed how to use the cli to generate a component inside a top level module folder, and also have the component automatically added the the module's declaration collection.

To create the module run this:

ng g module foo

To create the component inside the foo module folder and have it added to the foo.module.ts's declaration collection run this:

ng g component foo/fooList --module=foo.module.ts

And the cli will scaffold out the module and component like this:

https://i.stack.imgur.com/VOO37.png

--EDIT the new version of the angular cli behaves differently. 1.5.5 doesn't want a module file name so the command with v1.5.5 should be

ng g component foo/fooList --module=foo

Yay for the --module argument; the docs say "Allows specification of the declaring module." ; I would add --module specifies which existing module should be modified to import the module you are about to create
@TheRedPea I believe you meant to say " --module specifies which existing module should be modified to import the component you are ..."
Yep you're right! Existing module modified with reference to new component

You can try below command, which describes the,

ng -> Angular 
g  -> Generate
c  -> Component
-m -> Module 

Then your command will be like:

ng g c user/userComponent -m user.module

this works for angular 12, there's no need for .ts after .module so this is perfect. and as tony mentioned, It's worth adding --dry-run to the end of that just to see what will be affected, it's a nice sanity check

For Angular v4 and Above, simply use:

ng g c componentName -m ModuleName

Throws an error Specified module does not exist whereas module existed
You don't specify the name of the module, you specify the module's filename.
Works like charm! e.g. if your module file is user-settings.module.ts and you want to add a component public-info then the command will be: ng g c PublicInfo -m user-settings
This is the simplest and cleanest answer!

Mohamed Makkaoui

this is what worked for me :

1 -->  ng g module new-module

2 -->  ng g c new-module/component-test --module=new-module/new-module.module.ts

If you want to generate a component without its directory use --flat flag.


don't need to write .ts
--module=path-to-module worked form me thanks @Mohamed Makkaoui

First, you generate a module by executing.

ng g m modules/media

this will generate a module called media inside modules folder.

Second, you generate a component added to this module

ng g c modules/media/picPick --module=modules/media/media.module.ts

the first part of the command ng g c modules/media/picPick will generate a component folder called picPick inside modules/media folder witch contain our new media module.

the second part will make our new picPick component declared in media module by importing it in the module file and appending it to declarations array of this module.

Can you please explain more to how this answers the question?
Thank you for your note, I edited my answer as I'm a future reader @CertainPerformance

First generate module:

ng g m moduleName --routing

This will create a moduleName folder then Navigate to module folder

cd moduleName

And after that generate component:

ng g c componentName --module=moduleName.module.ts --flat

Use --flat for not creating child folder inside module folder

ng g c componentName --module=path-to-your-module-from-src-folder

example:

ng g c testComponent --module=/src/app/home/test-component/test-component.module

A common pattern is to create a feature with a route, a lazy loaded module, and a component.

Route: myapp.com/feature

app-routing.module.ts

{ path: 'feature', loadChildren: () => import('./my-feature/my-feature.module').then(m => m.MyFeatureModule) },

File structure:

app   
└───my-feature
│   │   my-feature-routing.module.ts
│   │   my-feature.component.html
│   │   my-feature.component.css
│   │   my-feature.component.spec.ts
│   │   my-feature.component.ts
│   │   my-feature.module.ts

This can all be done in the cli with:

ng generate module my-feature --module app.module --route feature

Or shorter

ng g m my-feature --module app.module --route feature

Or if you leave out the name the cli will prompt you for it. Very useful when you need to create several features

ng g m --module app.module --route feature

I have used the following command in the angular CLI version 8.3, and it worked by generating a specific component declared in a specific module.

move to the specific folder were we need the component to be generated cd Call the below generate command ng g c --module=

Example

 `ng g c login --module= app`

J
Junaid

TL;DR Try this. Specify the module name by module's file name(excluding the .ts extension) ng g c components/path-to-a-folder/component-name --module=app.module

Notes:

ng g c is short for ng generate component

If you want the component to be added in a different module, let's say in file collection.module.ts then use --module=collection.module instead of --module=app.module & you should be good to go.

Go to module level/we can also be in the root level and type below commands

ng g component "path to your component"/NEW_COMPONENT_NAME -m "MODULE_NAME"

Example :

ng g component common/signup/payment-processing/OnlinePayment -m pre-login.module

1.- Create your feature module as usual.

ng generate module dirlevel1/module-name

2.- You can specify the ROOT PATH of your project in --module ( only in --module, (/) root points to your PROJECT ROOT and IS NOT THE SYSTEM ROOT!!!)

ng generate component dirlevel1/component-name --module /src/app/dirlevel1/module-name.module.ts

Real Example:

ng generate module stripe/payment-methods-list
ng generate component stripe/payment-methods-list --module=/src/app/stripe/payment-methods-list/payment-methods-list.module.ts 

Output:

CREATE src/app/stripe/payment-methods-list/payment-methods-list.component.scss (0 bytes)
CREATE src/app/stripe/payment-methods-list/payment-methods-list.component.html (39 bytes)
CREATE src/app/stripe/payment-methods-list/payment-methods-list.component.spec.ts (768 bytes)
CREATE src/app/stripe/payment-methods-list/payment-methods-list.component.ts (322 bytes)
UPDATE src/app/stripe/payment-methods-list/payment-methods-list.module.ts (311 bytes)
[OK] Generated component!

Tested with Angular CLI: 9.1.4

Read the description of --route https://angular.io/cli/generate#module-command,

To archive such, you must add the route of that component-module to somewhere and specify the route name.

   ng generate module component-name --module=any-parent-module --route=route-path

I don't know if this is what brought you guys here, but I wanted to create a folder with a module, routing and component files. I wanted the component to be declared to the module I created.

For this I found this command to be really helpful.

ng g m path/to/folder/component --routing && ng g c path/to/folder/component

This should create a folder with 6 files.

CREATE path/to/folder/component/component-routing.module.ts (253 bytes)
CREATE path/to/folder/component/component.module.ts (297 bytes)
CREATE path/to/folder/component/component.component.html (26 bytes)
CREATE path/to/folder/component/component.component.spec.ts (655 bytes)
CREATE path/to/folder/component/component.component.ts (295 bytes)
CREATE path/to/folder/component/component.component.scss (0 bytes)
UPDATE path/to/folder/component/component.module.ts (379 bytes)

You can remove --routing if you don't want routing.

I am having the similar issues with multiple modules in application. A component can be created to any module so before creating a component we have to specify the name of the particular module.

'ng generate component newCompName --module= specify name of module'

Use this simple command:

ng g c users/userlist

users: Your module name.

userlist: Your component name.

If you have multiple apps declared in .angular-cli.json ( e.g. in case working on feature module)

"apps": [{
    "name": "app-name",
    "root": "lib",
    "appRoot": ""
}, {...} ]

You can :

ng g c my-comp -a app-name

-a stands for --app (name)

According to Angular docs the way to create a component for specific module is,

ng g component <directory name>/<component name>

"directory name" = where the CLI generated the feature module

Example :-

ng generate component customer-dashboard/CustomerDashboard

This generates a folder for the new component within the customer-dashboard folder and updates the feature module with the CustomerDashboardComponent

First run ng g module newModule . Then run ng g component newModule/newModule --flat

I created component based child module with specific Root Folder

That cli command below i specified,please check out

ng g c Repair/RepairHome -m Repair/repair.module

Repair is Root Folder of our child module

-m is --module c for compount g for generate

I ran into this issue today while scaffolding an Angular 9 application. I got the "module does not exist error" whenever I added the .module.ts or .module to the module name. The cli only needs the name of the module with no extension. Assuming I had a module name: brands.module.ts, the command I used was

ng g c path/to/my/components/brands-component -m brands --dry-run

remove the --dry-run once you've confirmed the file structure is correct.

Make a module, service and component in particular module

Basic:

    ng g module chat     
    ng g service chat/chat -m chat
    ng g component chat/chat-dialog -m chat

    In chat.module.ts:
        exports: [ChatDialogComponent],
        providers: [ChatService]

    In app.module.ts:

        imports: [
            BrowserModule,
            ChatModule
        ]

    Now in app.component.html:
        <chat-dialog></chat-dialog>

Firstly, you have to create a new module using the following command:

ng g module newModule

Then, you have to go inside that directory using the following command:

cd command  
cd newModule

And, now you can go ahead using the following command:

ng g component newComponent

and this component will be created in that module.

Add a component to the Angular 4 app using Angular CLI

To add a new Angular 4 component to the app, use command ng g component componentName. After execution of this command, Angular CLI adds a folder component-name under src\app. Also, the references of the same is added to src\app\app.module.ts file automatically.

A component shall have a @Component decorator function followed by a class which needs to be exported. The @Component decorator function accepts meta data.

Add a component to specific folder of the Angular 4 app using Angular CLI

To add a new component to a specific folder use the command ng g component folderName/componentName

I use this particular command for generating components inside a module.

ng g c <module-directory-name>/<component-name>

This command will generate component local to the module. or You can change directory first by typing.

cd <module-directory-name>

and then create component.

ng g c <component-name>

Note: code enclosed in <> represent user specific names.

You can generate a Module using ng generate module . Then use this command to generate a component related to that module, ng generate component --module=

If you already created your component without point to a module you can easily add it directly to your app module by adding it to declarations

@NgModule({
    declarations: [

    FileManagerDetailsComponent <---this is ur page component
