node-mutex

mutex object for large node applications with complex state and state update coroutines

How to use

const {createMutex, wait} = require('node-mutex');

const func1(signal, ...args) = () => {
    // async/await or sync code here
    // calls signal at the end of execution
    signal();
}

const func2(signal, ...args) = () => {
    // async/await or sync code here
    // calls signal at the end of execution
    signal();
}

// the following code ensures func2 does not access
// the critical section (the resource it protects)
// while func1 is mid-execution

const mutex = createMutex();
wait(mutex, func1, ...args1);
wait(mutex, func2, ...args2);
