Get started I spent weeks finding a way to refresh a page or a tab from the server once a user starts or restarts the browser. I was very surprised to find nothing about this topic. Let's dig into the context, tries and the solution I came up with. ContextTypically, once a user opens a browser and gets to a page, it directly provides the page in cache without refreshing any data from the server. Obviously, this only applies if the user is not in a private navigation. In this case, as a user, I always need to open the browser and then manually reload the page to get the last updated data. What? Am I too lazy? Sure I am a developer! My goal was to detect when the browser launches and automatically refresh the page or the tab at this moment so end users do not need to manually reload the page and updated data immediately come to their eyes! Sounds nice! TriesAs I am using a Service Worker that in my case handles expired pages and refreshing data (requesting data from the server if a page expired), I noticed the
navigation through the browser was always in a Here are the solutions I tried:
I still was unable to detect browser launch in my JavaScript. The solutionI finally came up with a solution using Performance and PerformanceNavigationTiming Level 2 APIs. ExperimentalPerformanceNavigationTiming Level 2 API is still at a Browser compatibilityBrowser compatibility is not as bad as expected for an experimental feature. Only Safari, iOS Safari and IE are not supported the solution.
Codeif ('performance' in window) { const navigationLastEntry = performance.getEntriesByType('navigation').pop(); if (navigationLastEntry && navigationLastEntry.type === 'back_forward' && navigationLastEntry.unloadEventStart === 0) { window.location.reload(true); } } UsageThis code does not need the DOM or the page to be loaded to be used. Actually it should be executed before these events are fired. I typically put this code at the first lines of my How it worksFirst the code checks Performance API is supported by the browser. It then get the last navigation entry. Finally it will reload the page only if:
Please note that the navigation is through the browser's history traversal operation
These 3 conditions all put together allow us to detect when the browser loads the page or tab after and only after the browser has launched. Any other Finally calling That’s it! At the end of the day that was a quite simple solution! Discussion and ContributionAs I am more of a back-end developer, please let me know if something's wrong or feel free to contribute if you have an alternative or better solution.
