In this guide, we will show you how to create and organize multiple apps in one Project or Workspace. The Angular CLI since version 6 allows us to create a multi-project workspace to manage multiple Angular apps. We do that first by creating an empty workspace. A Workspace is a collection of Angular apps, projects, or libraries. Later we can add multiple projects to the workspace.
Applies to: Angular 6 to the latest edition i.e. Angular 8. Angular 9, Angular 10

There are several advantages of having Multiple Angular Apps in One Project.
- One is you do not have to run the time consuming
npm installfor every app.
node_modulesfolder is shared with all the other apps saving disk space.
- All the apps can be updated to the next version easily.
- A single source-control repository (such as git).
Create the Empty Workspace
We create a new app using the
ng new <new> Angular CLI command. It creates and workspace with an initial Angular app with the name
<new> in the src folder. The
createApplication="false" option introduced in Angular 7 now stops the creation of the initial app. It only creates the workspace
ng new MultipleApps --createApplication="false"
The above command creates folder with the name
MultipleApps and configures the workspace. It does not create any
Add a new Project to Workspace
Now, to create a new app under the workspace, we need to use the
ng generate application command The first app created is marked as the default app.
ng generate application gettingStarted
If you use the
ng new inside the workspace, it will throw the following error.
The new command requires to be run outside of a project, but a project definition was found at “D:\MultipleApps\angular.json”
Run the App
There are three ways in which you can run the app.
- Use the
ng serve gettingStarted
- Use the
ng serve --project="gettingStarted"
- Open the
angular.jsonand locate the
defaultProjectand change the name of the project to
Add Another Project to the workspace
To create another app, run the
ng generate application again.
ng generate application exampleApp
Run the App
And use the
ng serve to run it
ng serve exampleApp
ng serve --project="exampleApp"
Building the App for Production
ng build to build the app with
ng build --prod --project="gettingStarted"
ng build --prod --project="exampleApp"
The folder structure is similar to the Single App workspace, except for the following
src folder is gone. Instead, we have a
projects folder. Each app we create gets its own folder under the
dist folder now has a folder for each of the new app.
angular.json, contains the configuration settings for the workspace. Here is the shortened version of
Angular.json for the above code.
"newProjectRoot": "projects", <== location of the apps
//This section contains the setting for the gettingStarted project
//This section contains the setting for the exampleApp project
"defaultProject": "gettingStarted" <== name of the default project
newProjectRoot: node points to the location of the
projects: contain a section for each app in the workspace. Each section contains configuration for the compiler.
defaultProject: The default project use, when you run the
ng build etc.
In this guide, we learned how to organize multiple apps in one single workspace/Project in Angular.
