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, 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-reactjs-renderer

Then, install the authenticators that you wish to use…

yarn add ual-scatter ual-lynx
With npm
npm i ual-reactjs-renderer

Then, install the authenticators that you wish to use…

npm i ual-scatter ual-lynx

Basic Usage

import React from 'react'
import ReactDOM from 'react-dom'
import { UALProvider, withUAL } from 'ual-reactjs-renderer'
import { Scatter } from 'ual-scatter'
import { Lynx } from 'ual-lynx'

import { MyApp } from './MyApp'

const myChain = {
  chainId: MY_CHAIN_ID,
  rpcEndpoints: [{
    protocol: MY_CHAIN_PROTOCOL,
    host: MY_CHAIN_HOST,
    port: MY_CHAIN_PORT,

const scatter = new Scatter([myChain], { appName: 'My App' })
const lynx = new Lynx([myChain], { appName: 'My App' })

const MyUALConsumer = withUAL(MyApp)

  <UALProvider chains={[myChain]} authenticators={[scatter, lynx]} appName={'My App'}>
    <MyUALConsumer />


A small example 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 an .env file, you can set environment variables for your chain particulars. Note that this file will not be version-controlled, nor should it be. The default settings for the file are…


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 ReactJS for more details.


After you set up your environment you can begin development. Make sure you are back in the / directory of the ual-reactjs-renderer package.

yarn link
yarn build -w

In a duplicate terminal tab, enter the following commands:

cd examples
yarn link ual-reactjs-renderer
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.

Epic Games Store ReactJS UI -NextJS, MaterialUI, ReactJS, TypeScript -Login Form Design #5

Hi, in this series we will try to build fullstack application with NestJS, NextJS, ReactJS, PostgreSQL and TypeScript. My aim is to build something bigger and more interesting. Features like authorization or using database are always tricky so I think it’s good to implement on your own to understand how they work. We will build both API and web application. Our app is a funny little approach to mimic something like a game library and we will try to recreate Epic Games Store.

Have you ever wondered how are real app design and written? In this series I will try to reproduce at least some functionalities of Epic Games Store. In the fifth episode I am recreating the login form. We’ll use NextJS, MaterialUI, ReactJS and TypeScript.
