Waitlist webview

A package that can be included in the chat webview component, or the Messenger webview host. You should pass one of either token or signedRequest depending on the environment.

Props:

• apiUrl: the URL of the webview-facing waitlist API.
• ioUrl: the URL of the contact-facing waitlist WebSocket server.
• token: a JWT token from the chat app.
• signedRequest: a signed request from a Messenger webview.

For dev/demo purposes, can be run in a standalone environment with npm run watch. Just set API_URL and IO_URL as environment variables, and supply a pre-generated token in CHAT_TOKEN. You can copy the token from any API request from the chat app. Environment variables can be set in an .env file.
