@iqitlab You probably use strict type checking in the tsconfig
, which requires all types to be defined and all variables initialized. Please try to update the TS code to:
searchText = new Subject<string>();
results: Observable<string[]>;
data: any = [
'red',
'green',
'blue',
'cyan',
'magenta',
'yellow',
'black',
];
constructor() {
this.results = this.searchText.pipe(
startWith(''),
map((value: string) => this.filter(value))
);
}
filter(value: string): string[] {
const filterValue = value.toLowerCase();
return this.data.filter((item: string) => item.toLowerCase().includes(filterValue));
}

thanks, it is working,
I am new to angular, and I have not done any setting in tsconfig,
may be these are default settings
Arkadiusz Idzikowski staff commented 3 years ago
@iqitlab It looks like this is caused by the new settings added by default in Angular v12. We will need to check the examples code in the documentation and adjust it accordingly, please let us know if you encounter any further problems with types.
