This library providers a Plain JS renderer around the Universal Authenticator Library.
It uses nothing but standard Javascript and should be supported across desktop and mobile.
About EOSIO Labs
EOSIO Labs repositories are experimental. Developers in the community are encouraged to use EOSIO Labs repositories as the basis for code and concepts to incorporate into their applications. Community members are also welcome to contribute and further develop these repositories. Since these repositories are not supported by Block.one, we may not provide responses to issue reports, pull requests, updates to functionality, or other requests from the community, and we encourage the community to take responsibility for these.
Getting Started
With yarn
yarn add ual-plainjs-renderer
Then, install the authenticators that you wish to use...
yarn add ual-scatter ual-lynx
With npm
npm i ual-plainjs-renderer
Then, install the authenticators that you wish to use...
npm i ual-scatter ual-lynx
Basic Usage
The below code will render a button to the DOM that will launch the Universal Authenticator Library modal.
import { UALJs } from 'ual-plainjs-renderer'
import { Scatter } from 'ual-scatter'
import { Lynx } from 'ual-lynx'
const myCallback = arrayOfUsers => {
// Execute on successful user authentication
}
const myChain = {
chainId: MY_CHAIN_ID,
rpcEndpoints: [{
protocol: MY_CHAIN_PROTOCOL,
host: MY_CHAIN_HOST,
port: MY_CHAIN_PORT,
}]
}
const myAppName = 'My UAL App'
const scatter = new Scatter([myChain], { appName: myAppName })
const lynx = new Lynx([myChain], { appName: myAppName })
const myAppRoot = {
containerElement: document.getElementById('my-ual-app')
}
const ual = new UALJs(myCallback, [myChain], myAppName, [scatter, lynx], myAppRoot)
ual.init()
Example
An example on how to use the library is provided in the examples folder.
Environment Set Up
A one-time environment setup is required prior to development. The following commands provides a quick starting point. Make sure you are in the examples/
directory.
cd examples
cp default.env .env
Now that you have a .env
file, you can set your chain particulars. Note that this file will not be version-controlled, nor should it be.
The default settings for the file are...
CHAIN_ID=12345
RPC_PROTOCOL=https
RPC_HOST=api.example.net
RPC_PORT=443
These values are taken from the local chain created by following the Developer Portal node set up instructions. (Note: if this is your first time following the tutorial you will need to install the eosio binaries here). These can be edited according to the requirements of your project if you have a different chain set up. They will be used as the chain data in the example app. See the Basic Example App for UAL with PlainJS for more details.
Development
After you set up your environment you can begin development. Make sure you are back in the /
directory of the ual-plainjs-renderer
package.
yarn
yarn link
yarn build -w
In a duplicate terminal tab, enter the following commands:
cd examples
yarn link ual-plainjs-renderer
yarn
yarn example
Open a browser at localhost:3000
to see a running instance of the example.
It is recommended to have at least two terminal tabs running so that yarn build -w
and yarn example
can run simultaneously creating an environment where changes are immediately reflected in the browser.
