react-native-meteor-oauth

Oauth2 login to a Meteor server in React Native

How?

import React, { Component } from 'react'
import View from 'react-native'
import Meteor from 'react-native-meteor'
import Login from 'react-native-meteor-oauth'

const meteorHost = '192.168.1.73:3000' // Put your local IP here if running in dev
Meteor.connect(`ws://${meteorHost}/websocket`)

export default () => {
  return (<View>
    <Login
      provider='Github'
      callbackUrl='http://localhost:3000/_oauth/github'
      meteorServerDomain={meteorHost}
      meteorServerProtocol='http'
      clientId='YOUR_GITHUB_CLIENT_ID'
    />
  </View>)
}

This module depends on react-native-meteor under the hood, which should then be used for subscriptions, method calling and so on once login has occurred.

The react-native-meteor docs specify that you should Meteor.connect only once in your app's parent component. The example above is reductive, but in a more realistic app this would involve having the Meteor.connect line in the parent component and requiring/using react-native-meter-oauth in subcomponents.

Which providers are supported?

Currently: Github, Google and Facebook.

Any other provider which allow login with Oauth2 can easily be added, which unfortunately does not presently include Twitter.

Props

• provider (required): one of ["Github", "Google", "Facebook"] for automatic config, but can be anything if you supply url and possibly extraRequestParam (see below).
• clientId (required): the client ID given by the OAuth provider.
• callbackUrl (required): the callback URL you specified to the OAuth provider corresponding to this clientId.
• meteorServerDomain (required): the domain of the Meteor server you're intending to log in to. Note localhost:3000 will not work here, as a device (even running in an emulator) has to connect over the (local) network. Use your dev server's local IP in dev.
• meteorServerProtocol (required): either http or https.
• scope (optional): a space-delimited string of requested scopes. Sensible but limited defaults are provided.
• url (optional): the url you want to use to request authorization from the OAuth provider. Theoretically, this (along with the param below) allows you to connect to any arbitary provider.
• extraRequestParams (optional): a dictionary of extra parameters which need to be provided in the authorization request to make OAuth work. For example, Google requires response_type="code", but this is already set by default.
• styles (optional): a dictionary of styles to overwrite the defaults, which are as follows:

{
  buttonContainer: { flexDirection: 'row', justifyContent: 'space-around' },
  button: { flex: -1 },
  buttonLogin: { backgroundColor: '#bbb'},
  buttonLogout: { backgroundColor: '#bbb'},
  buttonLoginText: { textAlign: 'center', paddingVertical: 12, paddingHorizontal: 40 },
  buttonLogoutText: { textAlign: 'center', paddingVertical: 12, paddingHorizontal: 40 },
  text: { textAlign: 'center', marginBottom: 15 },
  view: { flex: 1, alignSelf: 'stretch', justifyContent: 'center' }
}

Provider-specific styles are also merged into these for the Github, Google and Facebook.
