Using HALO in React

This section describes how to obtain HALO identity in react.

Obtaining identity

The user’s identity can be obtained by a react application with the useIdentity hook:

import React from 'react';

import { useIdentity } from '@dxos/react-client/halo';

export const MyComponent = () => {
  const _identity = useIdentity();
  return <>{/* ... */}</>;
};

The object returned is of type Identity.

Identity hook

When first creating an identity, the useIdentity hook will fire twice. Once with null, and then again with an identity when one has been established.

Once identity is established, a space must be created or joined in order to manipulate data.
