Node.js Event Loop |
https://dev.to/endeavourmonk/nodejs-event-loop-46oo
|
Node js Event LoopThe Node js event loop is a crucial concept in understanding how Node js manages asynchronous operations and handles concurrency Node js is designed to be non blocking and asynchronous which allows it to efficiently handle a large number of I O bound operations without getting blocked by any single operation Here s how the Node js event loop works Event Loop The event loop is a central component of Node js that manages all the asynchronous operations It constantly checks for new events in the event queue and processes them in a loop Event Queue The event queue holds various types of events such as callbacks timers and I O events that are generated as a result of asynchronous operations These events are added to the queue when they are triggered but are not executed immediately Callbacks Callbacks are functions that are provided as arguments to asynchronous functions They are executed once the corresponding asynchronous operation is completed and the event loop reaches the event in the queue This mechanism allows Node js to perform tasks without waiting for the completion of one task before moving on to the next Timers Node js provides two types of timers setTimeout and setInterval These timers schedule callbacks to be executed after a specified amount of time or at regular intervals I O Operations When Node js performs I O operations e g reading from or writing to files making network requests it does not block the execution of the rest of the program Instead it delegates the I O operation to the operating system and registers a callback to be executed when the operation is complete Microtask Queue In addition to the event queue Node js also maintains a microtask queue Microtasks are tasks that have higher priority than regular callbacks and are executed before the next iteration of the event loop Promises and certain APIs e g process nextTick add tasks to the microtask queue Here s a simplified step by step breakdown of how the event loop works Check the event queue for pending events If there are pending events dequeue an event and execute its associated callback Execute any microtasks that are in the microtask queue Perform any ready I O operations Check if any scheduled timers have expired If yes execute their callbacks Repeat the process from step The event loop allows Node js to handle multiple tasks concurrently without creating a separate thread for each task This concurrency model is efficient for I O bound operations but it s important to note that CPU bound operations can still block the event loop and should be offloaded to worker threads or other processes to maintain the responsiveness of the application Key Points The event loop is a single threaded loop which means that only one task can be executed at a time However the event loop can handle multiple tasks concurrently by running them in a non blocking manner The event queue is a FIFO first in first out queue which means that events are processed in the order in which they are added to the queue Microtasks are executed before regular callbacks which means that they have higher priority This is because microtasks are typically used to perform tasks that are related to the event loop itself such as scheduling timers and handling I O events The event loop can be blocked by CPU bound operations which are operations that require a lot of processing power To avoid blocking the event loop CPU bound operations should be offloaded to worker threads or other processes Hope you enjoyed this Please like this article Follow for more |
