Monorepos

This purpose of this project is to play with monorepos and Nx. This monorepo contains the following:

monorepos [app]
reusable-components, angular library with storybook stories [lib]
ui (design system) [lib]
monorepos-e2e [e2e cypress tests]
reusable-components-e2e [e2e cypress tests runnable over storybook]
server (nestjs server) [app]

Work that has been done

Installation process

create the repo npx create-nx-workspace monoreposeApp --preset=angular
create lib npx ng generate lib reusableComponents
install storybook for nrwl npm i -D @nrwl/storybook
create storybook config ng generate storybook-configuration reusable-components

Start storybook

ng run reusable-components:storybook

Nx commands

Adding capabilities to your workspace

Nx supports many plugins which add capabilities for developing different types of applications and different tools.

These capabilities include generating applications, libraries, etc as well as the devtools to test, and build projects as well.

Below are our core plugins:

Angular
- ng add @nrwl/angular
React
- ng add @nrwl/react
Web (no framework frontends)
- ng add @nrwl/web
Nest
- ng add @nrwl/nest
Express
- ng add @nrwl/express
Node
- ng add @nrwl/node

Generate an application

Run ng g @nrwl/angular:app my-app to generate an application.

You can use any of the plugins above to generate applications as well.

When using Nx, you can create multiple applications and libraries in the same workspace.

Generate a library

Run ng g @nrwl/angular:lib my-lib to generate a library.

You can also use any of the plugins above to generate libraries as well.

Libraries are sharable across libraries and applications. They can be imported from @monorepos/mylib.

Development server

Run ng serve my-app for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

Code scaffolding

Run ng g component my-component --project=my-app to generate a new component.

Build

Run ng build my-app to build the project. The build artifacts will be stored in the dist/ directory. Use the --prod flag for a production build.

Running unit tests

Run ng test my-app to execute the unit tests via Jest.

Run nx affected:test to execute the unit tests affected by a change.

Running end-to-end tests

Run ng e2e my-app to execute the end-to-end tests via Cypress.

Run nx affected:e2e to execute the end-to-end tests affected by a change.

Understand your workspace

Run nx dep-graph to see a diagram of the dependencies of your projects.
