Challenge: Cross-application request IDs

- [Instructor] Welcome to the chapter three challenge,…where we'll apply the cross-application transaction…tracing techniques we've been discussing…the entire rock paper scissors application.…This challenge is optional,…but it's a great way to reinforce…what we've done in this chapter.…There are four overarching objectives for this challenge.…We updated both web and players with express-request-id…and the request logger,…but the game service still needs to be updated.…We're logging the HTTP port when listening on web,…but not on players and games.…

We added support for request ID in the HTTP clients.…Let's require it to ensure everything is logged correctly.…Since it will be required,…we'll need to update all of the usages…of the games and players clients to send a request ID.…Let's break each objective down a little bit more.…There are two steps for express-request-id…and requestLogger in games,…and we've already done it elsewhere.…We just need to add and use express-request-id…in the games app…and add and use the request logger in the same file.…
