The library for fetching data from endpoints that uses continuationToken.

---

API answers something like this?

Response {
	result: any[];
	continuationToken?: string;
}

Use a partial-fetcher!

Why partial-fetcher so great? Because supports things like doAction, hasMore, fetchMore.

Usage

Service extends PartialFetcher<R, P>

• Declare protected fetch method

fetch(params: P, continuationToken: string): Observable<FetchResult<R>>

• Search your items with search method, update items with refresh, load more with fetchMore.

• Get your items from searchResult$, check if it has more with hasMore$, get loading state from doAction$ and subscribe to errors with errors$.
