useEOSHypersion

React hooks for EOS Hyperion State API data fetching. This can be used with any supported EOSIO-based blockchains.

All of the hooks wraps around useSWR from the swr library.

Install

npm install @cryptopuppie/useeoshyperion --save

Usage

Using the hooks is simple and made to be similar to useSWR for easier use.

import { useGetActions } from '@cryptopuppie/useeoshyperion'

export default function App() {
  const { data } = useGetActions(
    { account: 'fckedupmyacc', limit: 5 },
    'https://testnet.waxsweden.org'
  )

  return (
    <div>
      <h3>Actions</h3>
      <ul>
        {data?.actions.map((i) => (
          <li key={i.trx_id}>
            {i.trx_id} - {new Date(i.timestamp).toLocaleString()}
          </li>
        ))}
      </ul>
    </div>
  )
}

• With a Provider

  If you do not want to set the api everytime in each hook, you can use a provider.

  // Component.tsx
  import { useGetActions } from '@cryptopuppie/useeoshyperion'
  
  export default function Component() {
    const { data } = useGetActions({ account: 'fckedupmyacc', limit: 5 })
  
    return (
      <div>
        <h3>Actions</h3>
        <ul>
          {data?.actions.map((i) => (
            <li key={i.trx_id}>
              {i.trx_id} - {new Date(i.timestamp).toLocaleString()}
            </li>
          ))}
        </ul>
      </div>
    )
  }
  
  // App.tsx
  import { UseHyperionProvider } from '@cryptopuppie/useeoshyperion'
  import Component from './Component.tsx'
  
  export default function App() {
    return (
      <UseHyperionProvider endpoint="https://testnet.waxsweden.org">
        <Component />
      </UseHyperionProvider>
    )
  }

• Error handling

  All of the hooks export error objects, error and hasFailed. If hasFailed is true, the data object is null and error otherwise.

  import { useGetActions } from '@cryptopuppie/useeoshyperion'
  
  export default function App() {
    const { data, hasFailed, error } = useGetActions(
      { account: 'fckedupmyacc', limit: 5 },
      'https://testnet.waxsweden.org'
    )
  
    if (hasFailed) {
      return <p>{error.message}</p>
    }
  
    return (
      <div>
        <h3>Actions</h3>
        <ul>
          {data?.actions.map((i) => (
            <li key={i.trx_id}>
              {i.trx_id} - {new Date(i.timestamp).toLocaleString()}
            </li>
          ))}
        </ul>
      </div>
    )
  }
