A module for when you just need node to back off for a few milliseconds. ![]() There are 26 other projects in the npm registry using thread-sleep. Therefore, the above sleep() method will only suspend the execution of the function where you'll call it. Start using thread-sleep in your project by running npm i thread-sleep. Remember that due to the asynchronous nature of JavaScript, it is not possible to stop the entire program execution. But after the introduction of promises in ES6, we can easily implement such a feature in JavaScript to make a function sleep: const sleep = ( ms ) => timer ( ) // Start time -> T08:42:34.754Z // After 2s -> T08:42:36.763Z // After 4s -> T08:42:38.764Z However, this functionality is not available in JavaScript due to its asynchronous execution model. The setTimeout () method of the WindowOrWorkerGlobalScope mixin (and successor to tTimeout ()) sets a timer which executes a function or specified piece of code once the timer expires. Also, many sleep () solutions are only for Windows or only for Linux. ![]() ![]() Similarly, PHP has sleep(2), and Python has time.sleep(2) to make the program stops for 2 seconds. There’s no sleep () method in JavaScript, so you try to use the next best thing, setTimeout (). Existing sleep () solutions use a blocking while loop which uses 100 CPU. For example, in Java, you can use the Thread.sleep(2 * 1000) to halt the current thread execution for 2 seconds. These calls will block execution of all JavaScript by halting Node. Note that because this is a C++ module, it will need to be built on the system you are going to use it on. Many programming languages provide a sleep() function that pauses the execution of the code for a certain amount of time. Add sleep(), msleep() and usleep() to Node.js, via a C++ binding.
