This project was generated using Nx.

We have to keep the same validation rules for input values, for instance, a user's password. Usually we have endpoints like login, sign up, password confirmation in order to confirm some action, for instance, change email address.
It's implemented by using a custom decorator from
class-validatorlibrary. Take a look at@lazyorange/infrastructurelibrary. It containsIsPassworddecorator to reuse the same validates rules in one place, then we can extend this validator by adding more complex logic. -
We want to keep common logic inside module to be able reuse them across Nest.js application, how can I create to create a module for Nest.js? For instanse, we need to create a simple auth module, so our user will be able to register a user profile by providing username and password.
In order to accomplish this goal we can create auth module and add to module all needed services and entities.
Take a look at @lazyorange/auth in folder ./libs/auth. Underhood, it requires a user module to be able to use a user service that provide to us methods to find and create user.
🔎 Nx is a set of Extensible Dev Tools for Monorepos.
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:
- React
npm install --save-dev @nrwl/react
- Web (no framework frontends)
npm install --save-dev @nrwl/web
- Angular
npm install --save-dev @nrwl/angular

There are also many community plugins you could add.
Run nx g @nrwl/react: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.
Run nx g @nrwl/react:lib my-lib to generate a library.
You can also use any of the plugins above to generate libraries as well.
Libraries are shareable across libraries and applications. They can be imported from @lazyorange/mylib.
Run nx 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.
Run nx g @nrwl/react:component my-component --project=my-app to generate a new component.
Run nx 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.
Run nx test my-app to execute the unit tests via Jest.
