On a whole setTimeout is very useful method in Node.js and can be used across application with no major lines of code. Make sure while using setTimeout in loops it could be tricky at times and at times used quite easily.
As javascript is single threaded, using setTimeout allows the thread to run another events which are waiting in the queue and makes execution faster.
#Settimeout nodejs code#
The Node.js setTimeout method can be used at various places in javascript code where user need some operation to be performed after a delay of time. Since JavaScript is a single-threaded language. All can be achieved by using setTimeout method. The Node.JS setTimeout function is useful for delaying a function or code for a certain amount of time.
This becomes the major advantage of using setTimeout method is Node.js so that code execution, delay in response, processing response after a time period, redirecting or reloading contents after a time is exceeded, etc. Using Node.js framework, code runs asynchronously, and so at times requirement arises that the code execution which is asynchronous should be kept on hold for a minimum time period mention in setTimeout method. Given below are the advantages mentioned: For instance we have just printed few lines on console but it can be used for wider aspects like refresh the content, navigate to home page, alert the user, show timeout window, etc. Keep monitoring the console and once minimum 10 seconds time has passed you will see that delayedFuntion(1st parameter in setTimeout) is executed and whatever code is written inside this method gets executed. Note this is the minimum time of delay and not the exact time after which delayedFuntion(1 st parameter in setTimeout) will get executed. Now the setTimeout method starts executing and counting on the time which is defined in delayTimeInMS(2nd parameter in setTimeout). For Demo purpose we are just displaying simple HTML content as below. On Browser window HTML content can be rendered to display the Payment related details or asking for Payment information which later will redirect to the Payment Gateway. To start the application run the command node index.js in CMD.Īs our Node Application is listening on port 3000, once CMD says the application has started to listen on port 300, open chrome window or any other browser and launch local application on http with port number as 3000. VardelayTimeInMS = 10000 //Defining time in msĬonsole.log("Payment page exceeded the time limit, please refresh the screen") Ĭonsole.log('Demo Applications has started to listen on port 3000!') Res.end() //Writing content to html using res.write and so on) įunctiondelayedFuntion(param1, param2. SetTimeout(delayedFuntion, delayTimeInMS, param1, param2. Second parameter: It is the minimum time of delay required and should always be defined in milliseconds. Function on the fly or separately defined function both works fine here. First parameter: It should always be the function which needs delay in execution.
