An abstract TypeScript/JavaScript class that provides a results property,
and an abstract _searchAlgorithm method. results is read-only, and when
accessed returns the result of _searchAlgorithm().
_searchAlgorithm must be defined in a subclass.
view example
// Create a subclass...
export class UserSearchService extends AbstractSearchService {
searchText = '';
constructor(private __users){
}
protected _searchAlgorithm() {
// If no searchText, return all users:
if (this.searchText.length === 0) return this.__users;
// Else, check if searchText found in user's name:
else return this.__users.filter((user) => {
if (user.name === undefined) return false;
else return (user.name.includes(this.searchText));
});
}
}
let userSearch = new UserSearchService(getUsersSomehow());
userSearch.searchText = 'Jane Fonda';
console.log(userSearch.results);
// logs array of users whose names match 'Jane Fonda'results: any // read-onlyprotected abstract _searchAlgorithm(): any
npm i @writetome51/abstract-search-service
// if using TypeScript:
import { AbstractSearchService } from '@writetome51/abstract-search-service';
// if using ES5 JavaScript:
var AbstractSearchService =
require('@writetome51/abstract-search-service').AbstractSearchService;
