Developing / Contributing

Note that Facebook requires that you have HTTPS locally, despite their documentation to the contrary, so you will need to generate some SSL certs and point rollup config at them.

Put your app and client ids in an .env file

.env.local
VITE_GOOGLE_CLIENT_ID=<your-google-client-id>
VITE_FACEBOOK_APP_ID=<your-facebook-app-id>
``

```bash
pnpm dev
