Handle Race Condition in Node Js using Mutex
To handle race conditions in Node.js using a mutex, you can follow these steps:
- Import the
Mutex
class from theasync-mutex
package. - Create an instance of the
Mutex
class using thenew
keyword. - In the critical section of your code where race conditions can occur, use the
acquire
method of the mutex instance to acquire a lock. - Inside the
acquire
method, provide a callback function that contains the code you want to execute in the critical section. - Once the critical section is executed, release the lock using the
release
method of the mutex instance.
Here's an example code snippet that demonstrates how to handle race conditions using a mutex in Node.js:
const { Mutex } = require('async-mutex');
// Create a mutex instance
const mutex = new Mutex();
// Critical section code
mutex.acquire().then((release) => {
// Code to execute in the critical section
// Release the lock
release();
});
By using a mutex, you can ensure that only one thread or process can access the critical section at a time, preventing race conditions from occurring.
Please note that the above example uses the async-mutex
package, which provides a mutex implementation for asynchronous code in Node.js.
