Getting started

Note: be sure to read the Warning and Limitations section below.

yarn add ual-lynx

Dependencies

You must use one of the UAL renderers below.

React - ual-reactjs-renderer

PlainJS - ual-plainjs-renderer

Basic Usage with React

import { Lynx } from 'ual-lynx'
import { UALProvider, withUAL } from 'ual-reactjs-renderer'

const exampleNet = {
  chainId: '',
  rpcEndpoints: [{
    protocol: '',
    host: '',
    port: '',
  }]
}

const App = (props) => <div>{JSON.stringify(props.ual)}</div>
const AppWithUAL = withUAL(App)

const lynx = new Lynx([exampleNet])

<UALProvider chains={[exampleNet]} authenticators={[lynx]}>
  <AppWithUAL />
</UALProvider>

Warnings and Limitations

Using Lynx within your app is no different than using other authenticator plugins. However, if your application is being used from within the Lynx mobile app it is using an embedded browser to view the application. The main restriction is that the Lynx mobile app (and consequently the authenticator) can ONLY communicate with EOS Mainnet. So when setting up UAL, if you specify other chains it will not work. This is also true if you specify additional chains along with Mainnet. This can make testing difficult if your application is using contracts that are not yet deployed to Mainnet.

Testing on Mainnet

For a simple test to verify that authentication is working, you can stick with system contracts that are already present on Mainnet (e.g. transfer). In this case you can run a simple app locally fronted by ngrok. Lynx DOES have the ability to point to an app for testing wherever it is being hosted (i.e. the ngrok url), but the app must only use Mainnet. Below is a brief outline of how to test Lynx with a local instance of your app:

• Start up your test application
• If running locally, front it with ngrok
• In your Lynx mobile app
  • Login as usual
  • Navigate to the "Explore" tab
  • Open the test URL
    • On Android, click the menu dropdown in the upper-right corner and select "Test URL"
    • On iOS, tap on the top navigation bar 10 times and you'll be provided an input to put in a testing url

From this point on, the app should behave as expected.
