Install

yarn add rarity-react

Usage

  • Get an api key from ftmscan

  • Add a configuration file for rarity-react to your src path. You can call it almost anything, but here assume the name of the file is config.json.
    Open config.json and spec out your ftmscan settings and expansions. Here’s an example config.example.json

  • Add some wallet code like this

import { useWeb3 } from 'rarity-react'
export default function() {
  const { initialized, active, connect } = useWeb3()
  return <>
    {!(initialized && active) && <button onClick={connect}>connect wallet</button>}
  </>
}
import { RarityApp, useSummoners } from 'rarity-react'
import config from './config.json'
export default function() {
  const { summoners } = useSummoners()
  return <RarityApp config={config}>
    {summoners.map(s => {
      return <div>{s.expansions["core"].tokenId}</div>
    })}
  </RarityApp>
}
  • Make a custom expansion like this
import { Call, Contract } from 'ethcall';
import { RarityApp, RarityExpansionConfig, RarityExpansion, useSummoners } from 'rarity-react'
import config from './config.json'

export default function() {
  const customConfig = {
    id: 'custom-expansion-id',
    contract: '0x123... contract address ...456',
    abi: [... contract abi ...]
  } as RarityExpansionConfig

  const customExpansion = {
    id: 'custom-expansion-id',
    getSummonerCalls: (contract: Contract, summonerId: string) => {
      return[
        contract.customContractCall(summonerId)
      ] as Call[];
    },
    getSummonerExpansion: (callResults: any[]) => {
      const [ customProperty ] = callResults
      return { customProperty }
    }
  }

  const sideExpansions = [] as RarityExpansion[]
  sideExpansions.push(...configureExpansions([customConfig], [customExpansion]))

  const { summoners } = useSummoners()

  return <RarityApp config={config} sideExpansions={sideExpansions}>
    {summoners.map(s => {
      return <div>{s.expansions["custom-expansion-id"].customProperty}</div>
    })}
  </RarityApp>
}
