1. Problems with 1-basic-dynamic-form-approach
- We have the config and its type.
- But we have to create the formGroup and register control everytime, which we can move the logic to formService.
- But we have to do ngSwitchCase in the template, which we can move to one html file and we can use that file in every component template, but if take a look carefully, HTML part is exactly the design bottleneck where we create controls based on its type.
- In future we might have 20 type of controls, we can’t put all 20 switch blocks, we will be violating Single Responsibility Principle and Open/Closed Principle.
- My Idea is to extract each control into its own separate component and create those components dynamically using ngComponentOutlet.
2. Bits about this: 2-dynamic-forms-without-nested-group-array-support
- We have solved one problem by moving dynamic controls to their dedicated components, and resolving those compnonents via resolverService which helps in introducing new controls with ease, also less repititive work.
- Till now our implementation supports only controls, we don't support formGroups or formArrays.
- I also don't like the explicity [formGroup]="form" in every dynamic control component.
- But for now we will focus on introducing formGroup support to our dynamicForm Implementation.
3. Bits about 3-dynamic-forms-with-form-group-support
- FormGroup works fine now in our dynamic approach.
- But we have to use formGroup wrapper in every dynamic component, which i would like to remove and use more better approach.
- We will use viewProviders to resolve parent formGroup/formGroupName , as formControlName resolves the provider for ControlContainer using @Host, so it should find a provider in the same view, providers will not work, as @Host decorator.
4. Bits about 8-updating-error-messages-dynamically
- Currently we ard hard-coding the logic of error messages in the directive, we can make that configurable.
5. Bits about 9-configurable-error-state-matcher
- Implemented Configurable ErrorStateMatcher to configure the logic for rendering errors
This project was generated using Nx.
🔎 Smart, Fast and Extensible Build System
10-minute video showing all Nx features
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
There are also many community plugins you could add.
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.
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 shareable across libraries and applications. They can be imported from @dynamic-forms-poc/mylib.
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.
Run ng g component my-component --project=my-app to generate a new component.
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.
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.
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.
Run nx graph to see a diagram of the dependencies of your projects.
