What we're about

AGENDA:

Hold my context!
Miroslav Bajtoš | IBM

Abstract:

Preserving contextual data across asynchronous calls has been always tricky in Node.js land. For example, how to pass information about the current user or a correlation (transaction) id from the code processing incoming HTTP requests to the code calling a backend web service? Traditional runtimes like C and Java can utilize thread-local storage, which does not work for Node's single-threaded event loop.

The talk will describe different solutions people have been using (and abandoning) over the past 6+ years, dive into history of domains and async hooks, explain what's so difficult about context keeping, and finally offer the bright future that's coming with the recently introduced AsyncLocalStorage API.
