Deno library for blocking execution of a section of code to one at a time
This module was made to block access to a data store while something else in the event loop was modifying it.
Usage
Simply acquire
and release
the mutex when needed
import Mutex from "https://deno.land/x/awaitable_mutex/mod.ts"
const mutex = new Mutex();
const testFn = async () => {
const acquisitionId = await mutex.acquire();
// Do some data manipulation that only one process can access at a time
mutex.release(acquisitionId);
};
See more complicated examples in mod_test.ts. Specifically blocks data object access while fetching data to modify the data object
is probably most useful.
Testing
deno test --allow-env --allow-write --allow-net mod_test.ts
