Workers AsyncLocalStorage
Implementation of the Node.js AsyncLocalStorage API in Cloudflare Workers to maintain in-memory context across asynchronous operations using the nodejs_compat flag.
When To Use
Use when you need to persist and access stateful context, such as request IDs or user sessions, across multiple asynchronous function calls without passing them explicitly through every argument.

What This Skill Covers
- To enable built-in Node.js APIs and polyfills, add the nodejs\compat compatibility flag to your Wrangler configuration file. This also enables nodejs\compat...
- Main sections:
Background,Constructor,Methods,Static Methods,Examples.
Workflow
- Open the most relevant file under
docs/for the exact documented workflow and wording. - Open
schemas/files for exact structured contracts. - Open
examples/files for concrete requests, commands, snippets, and manifests. - Do not add behavior or configuration that is not present in the attached source files.
