WARNING: for EHRBase versions < 2.5.0 use release 1.0.0. Use latest version for EHRBase version >= 2.14.0 . No version available for 2.5.0<= EHRBase version<2.14.0_
This sofware helps in building openEHR aql queries. It needs a running instance of EHRBase in order to work. Its main capabilities are: creating the query with autocompletion and template visualization, saving queries on the running instance of EHRBase (called views) or locally (called snippets), performing queries, retrieving and showing the results, importing (writing into EHRBase) templates. More info at aql builder site.
At login are asked: Username, Password, Platform URL. If oauth2 is configured (see below on how to do it) then the client_secret is also requested. The platform URL has the form http://{yourehrbaseservername}:{yourehrbaseserverport}/ehrbase
NOTE: It is necessary to login with the EHRBase admin credentials to let all template and views methods work as intended.
Example of values for the default credentials:
- Username: ehrbase-admin
- Password: EvenMoreSecretPassword
- Platform URL: http://localhost:8080/ehrbase
Conda is optional. You can install with or without it.
Clone the repository:
git clone https://github.com/sasurfer/aqlbetter.git
creates, optionally, a conda environment and install nodejs and run install and build scripts:
cd aqlbetter
conda create --name aqlbetter
conda activate aqlbetter
conda install -c conda-forge nodejs
npm install -g @angular/[email protected]
cd projects/aql-builder/
npm install --save-dev @angular-devkit/build-angular --force
export NODE_OPTIONS=--openssl-legacy-provider
ng build aql-builder --prod
Modify 'localhost:8080' in projects/aql-builder/src/proxy.conf.json with {youehrbaseservername}:{yourehrbaseserverport}. This step, though optional, ensures that the app uses the EHRBase nodename, e.g., local.ehrbase.org, to create the full name for the queries. If the server in proxy is not recognized a default nodename will be used instead.
In the EHRBase directory creates two files: .env.ehrbase and docker-compose.yml
This is an example of .env.ehrbase (read by docker-compose.yaml):
SERVER_NODENAME=local.ehrbase.org

from the latest https://github.com/ehrbase/ehrbase.git copy the path to the file (included) tests/keycloak/import/ehrbase-realm-exported.json to this directory.
Modify the SPRING_SECURITY_OAUTH2_RESOURCESERVER_JWT_ISSUERURI server and port with your keycloak ip and port.
Start the services:
docker compose up
Use {aqlbetter_dir}/projects/aql-builder/src/environments/environment.prod.ts.OAUTH2 and modify the authorizationUrl according to your installation of keycloak. Remember that the address (server:port) must be the same as the one given in SPRING_SECURITY_OAUTH2_RESOURCESERVER_JWT_ISSUERURI in the EHRBase settings (172.31.0.2:8080 in the example). Rerun the build step:
ng build aql-builder --prod
Open a browser tab to localhost:8081/auth/admin and login to keycloak (admin/admin). Create, inside the ehrbase realm, a client named aqlbetter with client_id=aqlbetter, the urls set to http://localhost:4201 and Authentication and OAuth 2.0 Device Authorization Grant flagged on, choose client_id and client_secret as credentials and copy the newly created client_secret. Reset the ehrbase-admin password and copy it. client_secret and password for ehrbase-admin will be needed for the login form.
Run with:
ng serve aql-builder --port 4201 --prod
Open a browser tab to localhost:4201, fill the credentials and click "Start querying data".

Better UI Components is an Angular UI workspace consisting of libraries and tools to easily adopt openEHR concepts to your own projects.
It is based on Angular(10+) framework.
AQL builder is standalone full-featured application written in Angular (10+) for writing, executing AQL queries for clinical data and outputting results.
For detailed instructions on setting up and using the application see the AQL Builder README.md
To install this library run:
npm install @bettercare/aql-result-table
Once you have installed the library, include library to your project module:
@NgModule({
imports: [
...
AqlResultTableModule
],
bootstrap: [AppComponent]
})
export class AppModule {
}Then you can simply use it in your component html and provide input data:
<bui-aql-result-table
[aqlResultMetadata]="aqlResultMetadata"
[tablePresentation]="tablePresentation">
</bui-aql-result-table>* tablePresentation input is optional and is by default set to COMPACT view
class AqlResultMetadata {
aql?: string;
executedAql: string;
meta?: {href: string};
resultSet: unknown[] = [];
}
enum TablePresentation {
DETAILED = 'DETAILED',
COMPACT = 'COMPACT'
}Simply run dev server ng serve and you are good to go.
If you have access to EHR platform, you can also specify platform url and credentials in AppComponent.
serverConfig = {
url: undefined, // 'https://MY-EHR-PLATFORM/rest/v1/query',
username: undefined, // 'MY_USERNAME',
pwd: undefined, // 'MY_PWD'
};In this case you will be able to write and execute your custom AQLs. Results will be immediately shown in the table.
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.
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.
Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the --prod flag for a production build.
