All the OntimizeWeb components that use services for retrieving data have the attributes query-method, paginated-query-method, insert-method, update-method and deleted-method. The purpose of these attributes is allowing the component to use your own CRUD methods defined in your service. With this you can define, for example, as many query methods as you want. You can see the complete documentation here.
query-on-event
is an input of the OServiceBaseComponent. This input will reference to an event of the component that must listen to in order to perform its query. You can check how to use it here.
You can get that backend information in your login function by creating a function that returns the values that you need from the backend or from an API.

It will be something like this:
if (userName && userName.length > 0 && password && password.length > 0) {
const self = this;
this.loginService.login(userName, password).subscribe(() => {
self.getInfoFromBackend() //In this function is where you can get info from backend, connect to an API ...
.then(res => {
self.sessionExpired = false;
self.router.navigate(['../'], { relativeTo: this.actRoute });
})
.catch(e => console.log(e));
}, this.handleError);
}
While working with angular, many times we need to get data from URL. Data in url can be passed in two ways, first as a parameter and second as a query string.
We can get the value of query parameters using ActivatedRoute object, queryParamMap.
Accessing Query String Values From URL
Test URL: http://test-url.com/user-list?type=normal&list=active
Accessing the URL Parameters
Test URL: http://test-url.com/user-list/{type}/active
We can get the value of query parameters using ActivatedRoute object, queryParamMap.
Accessing Query String Values From URL
Test URL: http://test-url.com/user-list?type=normal&list=active
ngOnInit() {
this.route.queryParamMap.subscribe(queryParams => {
this.type = queryParams.get('type');
this.list = queryParams.get('list');
})
}
Accessing the URL Parameters
Test URL: http://test-url.com/user-list/{type}/active
ngOnInit() {
this.route.paramMap.subscribe(params => {
this.userType = params.get('type')
}) }
An Angular Application Environment is JSON configuration information that tells the build system which files to change when you use ng build and ng serve.
You can also create variables with different values in each of the environment files.
Check the official documentation to understand more about the environment configuration.

The application deep links will not work without the redirect rule on the server. All the deep links have to redirect to the application index.html by the server. To setup the tomcat to redirect any deep links:
1.-Configure the RewriteValve in server.xml
2.-Write the rewrite rule in rewrite.config
1.-Configure the RewriteValve in server.xml
2.-Write the rewrite rule in rewrite.config
You must use setValue function for each field that you want to set the value to achieve this.
When you are using this function and the values are not beeing setted you must listen to onFormModeChange event and set the value when form mode is the one that you want.
You can check how to use this event here.
