Question 1

How do I set up HTTPS with Ace in Elixir?

Accepted Answer

Start the service with TLS options including certfile and keyfile paths, as shown in the README's example. TLS is required for HTTP/2 support, and Ace handles configuration within Elixir's supervision tree for secure connections.

Question 2

What's the performance difference between Ace and Cowboy?

Accepted Answer

Ace is written in Elixir and may have different performance; the README links to a benchmark comparison. Cowboy is more battle-tested, but Ace offers modern features and better Elixir integration, so choose based on project needs.

Question 3

Can Ace be used with existing Elixir web frameworks like Plug?

Accepted Answer

Ace implements the Raxx interface, not Plug directly, so integration might require adapters. It's best suited for projects leveraging Raxx, whereas frameworks like Phoenix typically use Cowboy for Plug compatibility.

Question 4

How to implement streaming responses in Ace?

Accepted Answer

Use Raxx's streaming capabilities, as Ace integrates with the Raxx ecosystem. The README mentions Raxx tooling for streaming, allowing chunked responses and server-push features in your applications.

Question 5

Is Ace production-ready and how does it scale?

Accepted Answer

Ace is designed for production with supervision tree integration and HTTP/2 support, but its maturity is less than Cowboy's. It scales within Elixir's concurrency model, but evaluate based on community support and specific requirements.

Question 6

How to test my Ace server for HTTP/2 compliance?

Accepted Answer

Run `mix test --include ci:true` to execute h2spec tests, as described in the README. This downloads and runs h2spec to ensure HTTP/2 standards compliance, providing built-in validation tools.

Question 7

Ace or Cowboy: which is better for a new Elixir project?

Accepted Answer

Choose Ace if you prioritize HTTP/2 with native Elixir integration and Raxx tools, but accept a smaller ecosystem. Opt for Cowboy if you need stability, widespread adoption, and more plugins, as it's the most widely used server.
