Fire-entity NPM

Fire Entity

Fire Entity is a JavaScript library for storing and retrieving JSON documents from Firebase and caching them locally to reduce quota usage.

Installation

Use npm or yarn to install Fire Entity.

npm i -S fire-entity

yarn add fire-entity

Usage

import {Entity, EntityFireStore} from 'fire-entity';
import {firestore} from 'firebase/app';
import 'firebase/firestore';

const entityStore = new EntityFireStore(firestore(), {setOwner: true});

const entity: Entity = {
  name: 'Entity A',
  type: 'entities',
};
entityStore.insert(entity);

Instantiating an EntityStore, as shown above, is all you need in order to store and retrieve data from Firebase.

Querying entities

import {Entity, EntityFireStore} from 'fire-entity';
import {firestore} from 'firebase/app';
import 'firebase/firestore';

const entityStore = new EntityFireStore(firestore(), {setOwner: true});

// Retrieving all documents from a collection
entityStore.selectAll('collectionPath').then(entities => console.log(entities));

// Retrieving a subset of documents from a collection
entityStore.selectWhere(
  'collectionPath',
  [{prop: 'age', op: '>', val: 20}]
).then(entities => console.log(entities));

Listening for entity changes

import {Entity, EntityFireStore} from 'fire-entity';
import {firestore} from 'firebase/app';
import 'firebase/firestore';

const entityStore = new EntityFireStore(firestore(), {setOwner: true});

// Listening for changes to all documents from a collection
entityStore.listenAll('collectionPath').subscribe(entities => console.log(entities));

// Listening for changes to a subset of documents from a collection
entityStore.listenWhere(
  'collectionPath',
  [{prop: 'age', op: '>', val: 20}]
).subscribe(entities => console.log(entities));
