I have multiple methods that contain individual get method but in component How to Call Multiple Rest API and Subscribe in component i.e. calling multiple methods in one subscribe.
/**
* Get current User from the server.
*
* @returns {json} current user.
*/
public getCurrentUser(): any {
return this.http.get(this.baseUrl)
.pipe(map((res: any) => res.data));
}
/**
* Get all device statuses from the server.
*
* @returns {json} all asset statuses.
*/
public getDeviceConditions(): any {
return this.http.get(this.baseUrl)
.pipe(map((res: any) => res.data));
}
Suppose the above two methods I want to call withing one subscribe.

To call multiple API parallelly and get a combined response in one short we can use forkJoin method of rxjs.
You can do something like this as shown below,
forkJoin([
getCurrentUser(), //observable 1
getDeviceConditions() //observable 2
]).subscribe(([users, deviceConditions]) => {
// When Both are done loading do something
});
