Food Fight Demos

This folder contains examples of usage of Food Fight in different scenarios

Direct - ping-pong

This is a simple demo showing usage of Direct transport in simple Ping-Pong scenario

Startup

1. Build the library from the main directory: yarn install && yarn build
2. Run one terminal in demos/direct-ping-pong subdirectory
3. Start node ping-pong.js in the terminal
4. You should see flow of messages
5. Every 4th message should get timed out (to show timeout scenario)

Implementation explanation

1. We start by calling ping with counter that equals 0.
2. We call pong from within ping with provided counter
3. We call ping from within pong with increased counter 4 We rinse and repeat until counter reaches 10 5 As we delay each pong by 50ms and out max timeout equals 500ms, last pings and pongs are timed out
   • Notice that we are still waiting for the outermost ping resolution - this is the one that reaches timeout!
4. All the pings and pongs are resolved with final counters (no more recurrency, returning final counter)
   • Notice that we get 20 (well, actually - 19) final messages (2 for each ping-pong pair), as we have 10 ping-pong cycles
