Unsubscribing an observer while running create, update or delete operations on modal in Laravel

Today I was trying to copy some data from one application to another application. The Data has some nested relationships so I created a custom feature to fetch the data using Apis and insert them one by one into my destination application. My problem while inserting the data was, there was an observer is set to File.php (for example) model that was running run logic to upload the incoming file to AWS s3 Cloude storage. But I am not really uploading anything while inserting the data. So, I want to stop the Observer from running the functionality while I was running my custom feature. While looking for some solution to my problem I came to a solution that I would like to share with you. File::unsetEventDispatcher(); I used this function call before running the logic only once and my observer stopped executing the code on Create and Update model event.

Call async function in loop for array and update the exiting array Javascript and Node Js

Here is a good example of the code to call async function in loop for element of an array and update the exiting array. In this example I have used the Array.prototype.entries() function to get the index and value of each array item of a simple array. Array.prototype.entries() method helps to iterate an array with index and element. function timeout(ms) { return new Promise(resolve => setTimeout(resolve, ms)); } async function resolveAfter2Seconds(num) { await timeout(2000); return num; } async function main() { let arr = ["Saab", "Volvo", "BMW"]; for (let [index, val] of arr.entries()) { console.log(index, val); console.log(await resolveAfter2Seconds(val)); } } main();
