Step 1. Install Erlang.
Step 2. Download Chicago Boss and extract.
Step 3. Get thee to a terminal
cd ChicagoBoss-0.6.3
make
make app PROJECT=rahm
cd ../rahm
Step 4. Write an application. Put this into src/controller/rahm_greeting_controller.erl:
-module(rahm_greeting_controller, [Req]).
-compile(export_all).
hello('GET', []) ->
{output, "<strong>Rahm says hello!</strong>"}.
Step 5. Start the development server
./init-dev.sh
Step 6. Try it out in a web browser: http://localhost:8001/greeting/hello
Step 7. Stop the development server
q().
Step 8. Write a conformance test. Put this into src/test/functional/rahm_test.erl:
-module(rahm_test).
-compile(export_all).
start() ->
boss_web_test:get_request("/greeting/hello", [],
[ fun boss_assert:http_ok/1,
fun(Res) -> boss_assert:tag_with_text("strong",
"Rahm says hello!", Res) end ], []).
Step 9. Build for production and run the conformance test
./rebar compile
./rebar boss c=test_functional
Step 10. There is no step 10!
Just kidding, you need to start the production server.
./init.sh start
And if you need to stop it:
./init.sh stop
Now ask all your friends to visit your web page and try to get Rahm to stop saying hello.
It simply can't be done!
