brunhilde (tested with Erlang OTP R19, R20)

Serving many users concurrently is what brunhilde does for a living!

brunhilde is a minimal (~715 LOC) Erlang/OTP web server, designed for rapid prototyping and hackathons/coding competitions. As simple as possible, so that it can quickly be modified or debugged. It is not designed to provide high performance or be used in production.

Dependencies:

• rebar3 (https://www.rebar3.org/)
• jsx: fetched from rebar3
• erlydtl: fetched from rebar3

Usage:

To start brunhilde standalone, do:

make build start

To embed brunhilde in another OTP application, see: brunhilde_ext.

For an example of a small (but covering POST, GET, redirects, etc), see: musiklistan.

Dialyzer:

make dialyzer (requires existing PLT)

Running virtual servers/apps:

Virtual servers are defined in servers/ and have to use the rest_handler behaviour. Give a list of virtual servers to start in brunhilde.conf.

For example:

#{start_observer => false,
  start_debugger => false,
  use_reloader   => true,
  servers =>
   [ #{server_name   => battleship,
       instance_name => battleship_serv,
       port          => 28251,
       workers       => 10,
       transport     => http}

   , #{server_name   => helloworld,
       instance_name => helloworld_serv,
       port          => 5030,
       workers       => 5,
       transport     => http}

   , #{server_name   => helloworld,
       instance_name => helloworld_serv2,
       port          => 5031,
       workers       => 10,
       transport     => http}

   , #{server_name   => secure,
       instance_name => secure_serv,
       port          => 4430,
       workers       => 10,
       transport     => {https,
                        "cert.pem",
                        "privkey.pem",
                        "fullchain.pem"
                        }
      }
   ]}.
