@meteorrn/core

Meteor React Native

A set of packages allowing you to connect your React Native app to your Meteor server, and take advantage of Meteor-specific features like accounts, reactive data trackers, etc.

Full API Documentation

If you're new to React Native, you can view a guide to using React Native with Meteor on the Official Meteor Guide

New Package Name

Meteor React Native is now published under @meteorrn/core. We will continue to publish updates to the meteor-react-native repository until 2.1.0. We recommend updating to the new package name as soon as possible.

Installation

1. npm install --save @meteorrn/core
2. Confirm you have peer dependencty @react-native-community/netinfo installed
3. Confirm you have @react-native-community/async-storage@>=1.8.1 installed. If you are using Expo, or otherwise cannot use @react-native-community/async-storage, see Custom Storage Adapter below.

A note on AsyncStorage

This package uses @react-native-community/async-storage by default. This may cause issues if you are using certain React Native versions, or if you are using Expo. To use a custom AsyncStorage implementation, pass it as an option in Meteor.connect:

import { AsyncStorage } from 'react-native';

// ...

Meteor.connect("wss://myapp.meteor.com/websocket", { AsyncStorage });

If you are using the AsyncStorage API yourself, its important that you use the same version that MeteorRN is using, or issues could be caused due to the conflicting versions. Make sure you are using the same AsyncStorage you pass into Meteor (or @react-native-community/async-storage if you aren't passing anything), or you can use MeteorRN's package interface.

Basic Usage

import Meteor, { Mongo, withTracker } from '@meteorrn/core';

let MyCol = new Mongo.Collection("mycol");

Meteor.connect("wss://myapp.meteor.com/websocket"); // Note the /websocket after your URL 

class App extends React.Component {
    render() {
        let {myThing} = this.props;
        
        return (
            <View>
                <Text>Here is the thing: {myThing.name}</Text>
            </View>
        );
    } 
}

let AppContainer = withTracker(() => {
    Meteor.subscribe("myThing");
    let myThing = MyCol.findOne();
    
    return {
        myThing
    };
})(App)

export default AppContainer;

Companion Packages

There are a few official companion packages available to add new features. Some packages provide a polyfill for Atmosphere packages, others simplify your app's integration with Native features (like local data storage).

Beta Packages:

• @meteorrn/ndev-mfa: Package that allows your RN app to work with meteor/ndev:mfa
• @meteorrn/local: Package for storing of data locally that works seamlessly with MeteorRN by injecting data into a local minimongo collection

Planned/Upcoming Packages:

• @meteorrn/queued-calls: Package that allows you to queue Meteor calls that will be performed when internet/server is available

If you have an idea for a companion package, please open an issue. If you would like to publish your own companion package, we recommend a package name with the prefix mrn-.

Compatibility

For React Native >=0.60.0 use this package

For React Native <0.60.0 use react-native-meteor.

Migrating from react-native-meteor:

• cursoredFind is no longer an option. All .find() calls will return cursors (to match Meteor)
• MeteorListView & MeteorComplexListView have been removed
• CollectionFS has been removed
• createContainer has been removed
• Mixins (connectMeteor) have been removed
• composeWithTracker has been removed

Package Interface

To ensure that MeteorRN companion packages use the same versions of external packages like AsyncStorage as the core, @meteorrn/core provides a package interface, where companion packages can access certain packages. Currently package interface returns an object with the following properties:

• AsyncStorage

Usage

import Meteor from '@meteorrn/core';

const {AsyncStorage} = Meteor.packageInterface();
