Question 1

How to set up Bullet with Cowboy for real-time updates?

Accepted Answer

Define a dispatch rule in Cowboy's routing with bullet_handler and specify a custom handler module implementing init, stream, info, and terminate functions, as detailed in the README's dispatch and handler sections. This allows you to manage connection lifecycle events.

Question 2

Is Bullet still a good choice for new Erlang projects?

Accepted Answer

No, Bullet has been discontinued and archived, meaning it's no longer maintained. For new projects, consider alternatives like Phoenix Channels or other active libraries that support modern standards and provide ongoing updates.

Question 3

Bullet vs Phoenix Channels: which is better for real-time Erlang apps?

Accepted Answer

Bullet is simpler and integrated with Cowboy but discontinued and jQuery-dependent. Phoenix Channels is part of the actively maintained Phoenix framework, offering more features like presence and channels, making it better for long-term, scalable projects.

Question 4

Can I use Bullet without jQuery on the client side?

Accepted Answer

No, the provided JavaScript library requires jQuery. If you need to avoid jQuery, you would have to modify or rewrite the client-side code, which is complex and impractical due to the project's discontinued status.

Question 5

How does Bullet handle WebSocket fallback in older browsers?

Accepted Answer

Bullet automatically detects client capabilities and falls back from WebSocket to EventSource or XHR long-polling, ensuring connectivity even when WebSocket is not supported, as described in the README's transport abstraction feature.

Question 6

What are the alternatives to Bullet for Cowboy-based apps?

Accepted Answer

Since Bullet is discontinued, consider using raw Cowboy WebSocket handlers or integrating with other libraries like Gun for HTTP/2. For robust real-time features, migrating to the Phoenix framework with Channels is often recommended.
