use-discord

A React context hook to log in using a Discord identity without a server-side component.

The code will refresh login and role status every hour. I use a service worker to handle the redirect_uri. I'll work on getting that added as something you can import and stick in your fetch handler.

Installation

npm i use-discord

Use

In your app's root somewhere:

    <DiscordProvider
      client_id={'969261945310031913'}
      guilds={['783410937902006374', '551763693378076683']}
    >
      <TheRestOfYourApp />
    </DiscordProvider>

In a component hook:

const MyComponent = () => {
  const discord = useDiscord();
  return <Menu>
    {
      discord.isLoggedIn
        ? <MenuItem onClick={discord.logout}>Log out of Discord</MenuItem>
        : <MenuItem onClick={discord.login}>
            <Typography>Log in to Discord</Typography>
          </MenuItem>
    }
  </Menu>
}

In your service worker:

const { onMessageHandler, fetchHandler } = require('use-discord');

addEventListener('fetch', (event) => {
  if (fetchHandler(event)) return;

  ...
});
addEventListener('message', onMessageHandler);
