# NgxAngularQueryBuilder
The goal of this project is to enable Angular 12+ support for the original [angular2-query-builder](https://github.com/zebzhao/Angular-QueryBuilder). It is _not_ production ready. This project may not be maintained. Should the original project become active again, this library may be abandoned.
## I suggest forking this project if it is critical to your project because I may not update this regularly. If you want to contribute to maintaining this project open an issue.
The changelog for the package is here: https://github.com/raysuelzer/ngx-angular-query-builder/blob/main/projects/ngx-angular-query-builder/CHANGELOG.md
This project uses code from https://github.com/designermanjeets/Angular-QueryBuilder a fork of https://github.com/zebzhao/Angular-QueryBuilder both developed under the MIT License.

## Customizing with Angular Material
Example of how you can completely customize the query component with another library like Angular Material. For the full example, please look at the [source code](https://github.com/zebzhao/Angular-QueryBuilder/blob/master/demo/src/app/app.component.ts) provided in the demo.
#### `app.component.html`
```html
+ Rule
+ Ruleset
- Ruleset
remove
And
Or
{{field.name}}
{{value}}
{{ opt.name }}
...
```

## Dependencies
- Angular 12+
This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 12.2.13.
## Development server
Run `ng serve` 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 generate component component-name` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`.
## Build
Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory.
## Running unit tests
Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
## Running end-to-end tests
Run `ng e2e` to execute the end-to-end tests via a platform of your choice. To use this command, you need to first add a package that implements end-to-end testing capabilities.
