A simple anoymous chat app that shows how you can create offline apps with React and RxDB, using a local IndexedDB database. This project was bootstrapped with Create React App. Node version 6 or superior.RxQuery. A query allows to find documents in your collection. Like most other noSQL-Databases, RxDB uses the mango-query-syntax.It is also possible to use chained methods with the query-builder plugin.. find() To create a basic RxQuery, call .find() on a collection and insert selectors. The result-set of normal queries is an array with documents.RxDB is a client-side database that follows the principles of reactive programming. It is built on top of IndexedDB, the native browser database, and leverages the RxJS library for reactive data handling.

isRxDocument. Returns true if the given object is an instance of RxDocument. Returns false if not. const is = isRxDocument(myObj); A document is a single object which is stored in a collection. It can be compared to a single record in a relational database table. You get an RxDocument either as return on inserts, or as result-set of queries.

Indexes . RxDB supports secondary indexes which are defined at the schema-level of the collection. Index is only allowed on field types string, integer and number.Some RxStorages allow to use boolean fields as index.. Depending on the field type, you must have set some meta attributes like maxLength or minimum.This is required so that RxDB is able to .A good way to learn using RxDB database with React Native is to check out the RxDB React Native example and use that as a tutorial. If you haven't done so yet, you should start learning about RxDB with the Quickstart Tutorial.

RxDB internally uses the rxjs library for observables and streams. All functionalities of RxDB like query results or document fields that expose values that change over time return a rxjs Observable that allows you to observe the values and update your UI accordingly .

In the fast-paced world of mobile app development, hybrid applications have emerged as a versatile solution, offering the best of both worlds - the web and native app experiences. One key challenge these apps face is efficiently storing and querying data on the client's device. Enter RxDB, a powerful client-side database tailored for ionic hybrid applications.

The way RxDB hashes and normalizes a schema has changed. To migrate stored data between the RxDB versions, therefore you have to increase your schema version by 1 and add a migration strategy.
