@styra/run-sdk-react

The Styra Run React SDK

Installation

npm install --save @styra/run-sdk-react

Quick start

A complete example:

import React from 'react'
import ReactDOM from 'react-dom/client'

import { Authz, AuthzProvider, Denied } from '@styra/run-sdk-react'

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <AuthzProvider endpoint="/api/authz">
    <App/>
  </AuthzProvider>
);

const Resource = {
  CREATE: 'tickets/create/allow',
  RESOLVE: 'tickets/resolve/allow'
}

function App() {
  return (
    <div>
      <Authz path={Resource.CREATE}>
        <button authz={Denied.HIDDEN}>Create</button>
      </Authz>
      
      <Authz path={Resource.RESOLVE}>
        <button authz={Denied.DISABLED}>Resolve</button>
      </Authz>
    </div>
  )
}

Components

<AuthzProvider/>

Use the AuthzProvider component to configure your Styra Run API proxy endpoint, which enables batch query requests with caching to your application:

• endpoint specifies the API to check authorization decisions
• defaultInput every decision would be passed in this input unless overridden

import React from 'react'
import ReactDOM from 'react-dom/client'

import { AuthzProvider } from '@styra/run-sdk-react'

import App from './App'

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <AuthzProvider endpoint="/api/authz" defaultInput={{tenant: 'acmecorp'}}>
    <App/>
  </AuthzProvider>
);

<Authz/>

Use the Authz component to conditionally render components based on whether the current user is allowed or denied for the specified queries. Add the authz property to define how to render these components, options are:

• Denied.DISABLED adds a disabled element attribute if authorization was denied
• Denied.HIDDEN adds a hidden element attribute if authorization was denied

import React from 'react'

import { Authz, Denied } from '@styra/run-sdk-react'

export default Ticket() {
  return (
    <div>
      <Authz path="tickets/resolve/allow" input={{id: 'ticket1234'}}>
        <button authz={Denied.DISABLED}>Resolve</button>
      </Authz>

      <Authz query={[
        {path: 'tickets/read/allow'},
        {path: 'tickets/create/allow', input={{id: 'ticket1234'}}}
      ]}>
        <button authz={Denied.HIDDEN}>Create</button>
      </Authz>
    </div>
  )
}

Hooks

useAuthz

This hook provides flexibility that requires more control over the Authz component. This hook provides:

• a way to preload authorization requests
• determines which authorization requests are loading
• a result array containing in order the queried decisions

useAuthz takes in an array of objects (path, input):

import React from 'react'

import { useAuthz } from '@styra/run-sdk-react'

export default Ticket() {
  const { isLoading, result } = useAuthz([
    {path: 'tickets/create/allow'}, 
    {path: 'tickets/resolve/allow', input: {id: 'ticket1234'}}
  ])
  
  if (isLoading) {
    return null
  }

  const [isCreateAllowed, isResolvedAllowed] = result
  
  return (
    <div>
      {isCreateAllowed && <button>Create</button>}
      <button disabled={isResolvedAllowed}>Resolve</button>
    </div>
  )
}
