simple-rx-pouchdb

You might need to do some setup on your pouch db, local/remote replicate etc.  
I usually check if the remote is up first, once you have it you can pass it into the   
class SimpleRxPouch that has a constructor definition: constructor(public pouch: Observable<PouchDB>)  
It assumes the pattern of pouch db per entity collection where all entities extend the interface  
{ _id: string }    


getPouchDB(): Observable<PouchDB>;
listenForChangesOnEntity(_id: string): Observable<any>;
listenForChangesOnEntities(): Observable<any>;
/**
 * Gets all entities
 *
 * @returns Observable<T[]> all entities
 */
getAllEntities<T>(): Observable<T[]>;
/**
 * Gets one entity
 *
 * @param _id
 * @returns Observable<T> one entity
 */
getOneEntity<T>(_id: string): Observable<T>;
/**
 * Updates entity
 *
 * @param entityPartial
 * @returns Observable<boolean> success
 */
updateEntity<T>(entityPartial: Partial<T>): Observable<boolean>;
/**
 * Creates entity
 *
 * @param entityPartial
 * @returns Observable<boolean> success
 */
createEntity<T>(entityPartial: Partial<T>): Observable<boolean>;
/**
 * Watches all
 *
 * @returns Observable<T[]> all
 */
watchAll<T>(): Observable<T[]>;
/**
 * Watches id
 *
 * @param id
 * @returns Observable<T>
 */
watchId<T>(id: string): Observable<T>;
/**
 * Find and watch result set
 *
 * @param [selector]
 * @param [sort]
 * @param [fields]
 * @returns Observable<T[]> result set
 */
findAndWatch<T>(selector: any, sort?: string[], fields?: string[]): Observable<T[]>;
