From Discord: Handling asynchronous operations with `Ref` in the Effect Typescript library can indeed be tricky...
Summary
In the conversation, the user, liambutlerlawrence, was dealing with asynchronous operations on a Ref in the Effect Typescript library, which requires synchronous modifications. The issue arose when trying to use a Ref and Context to manage a CookieJar from the tough-cookie library, as its setCookie method is asynchronous. This led to race conditions because asynchronous operations on the Ref required separate get and set calls.
User maxwellbrown suggested using SynchronizedRef, which handles effectful operations safely by wrapping modifications in a semaphore, preventing race conditions. This solution was exactly what liambutlerlawrence needed.
Key Takeaways:
Refin Effect Typescript requires synchronous modifications, which can lead to race conditions when dealing with asynchronous operations.SynchronizedRefis the solution for handling effectful transformations on state, providing safety with concurrent asynchronous modifications.- Documentation can be improved by linking related concepts, such as directing users dealing with async operations to consider
SynchronizedRef.
