This app demonstrates a problem that the 0.9.x branch of active_model_serializers
causes when using the streaming functions provided by ActionController::Live.
To test with this repo, first check out the code and then go into the project directory.
Then install all the gems:
bundle install
Then run the server by doing:
foreman start -f Procfile.dev
And then test the streaming response by doing:
curl http://localhost:3001/streaming_test/index
You'll see a five second delay and then hello world will be output
five times all at once.
hello world
hello world
hello world
hello world
hello world
Now stop the server by hitting Ctl-C in the terminal where foreman is
running and then open the Gemfile and comment out the line for the
0.9.8 version of active_model_serializers and uncomment the line
for 0.10.0.
Then:
bundle install
And restart the server:
foreman start -f Procfile.dev
And then test the streaming response again.
curl http://localhost:3001/streaming_test/index
This time you should see one of hello world output immediately,
and then a 1 second delay, then you'll see another one, and then
another delay, and so on, until there are five instances.
