I am looking for a solution to wrap rxjs subscribe's next callback with my own function:
type Handler<T> = (value: T) => void;
export function withTryCatch<T>(callback?: Handler<T>): Handler<T> {
return (value: T) => {
try {
callback?.(value);
} catch(err) {
// error handling
}
};
}
The issue with the example below is that it does not automatically infer the type from subscribe's next function. In this case, the user type is identified as unknown. The only way to set the user's desired type is by explicitly defining the type variable T in withTryCatch (see commented code below - withTryCatch<UserModel>).
store$
.pipe(
map(userSelector)
)
// .subscribe(withTryCatch<UserModel>((user) => {
.subscribe(withTryCatch((user) => {
// possible error code
}));
Is there a way to avoid using withTryCatch<UserModel>?
