![]() ![]() This is useful for events such as pagehide, where you want to bypass the timeout and go directly to an idle state. If you decide to enable worker timers, take a look at Testing Considerations for information on how to mock these timers for your test suites.Īny events added to immediateEvents will immediately switch the user into an idle or prompted state, calling onIdle or onPrompt respectively. Main thread timers are the default to allow projects that wish to omit worker thread timers to tree shake out the worker code. If this is not an option, you can omit the timers property and use the default main thread timers. It is strongly suggested that you update your rule to allow the worker to run so the timers are accurate. The worker is provided via a blob URL and this can cause strict CSP rules to be violated. In addition, an implementation of Web Worker thread timers has been exported to keep timers alive when a window is throttled by the browser. To combat this, the timers interface has been exposed as a property. This can cause IdleTimer to produce delayed and/or inaccurate results. When a window is backgrounded, the browser will throttle timers in an attempt to save CPU cycles. This is not necessarily a breaking change but good to be aware of while migrating. If you were to leave these props set in your useIdleTimer hook or withIdleTimer higher-order component, they wouldn't do anything. There is no good reason a user would want to set either of them to false and as such, they have been removed to reduce complexity and API surface. The passive and capture props have been removed and are automatically set to true. Non-Breaking Changes # Removal of passive and capture Props # If you want to get the old timestamp you can just call getLastActiveTime().getTime() and getLastIdleTime().getTime(). This will eliminate the need to cast to a Date before formatting. The getLastActiveTime() and getLastIdleTime() methods now return Date objects instead of a timestamp. Setting it too low will cause a lot of messaging between tabs. Set it to the maximum amount of drift between timeouts that is tolerable for your project. ![]() By default, this property has a value of 0 which is equivalent to disabled. Every user action that is defined in the events array will be replicated to all tabs, thus keeping the timeouts across tabs roughly in sync. It takes a number that represents the throttle value in milliseconds for the sync function. See more about leader election in the next section.Ī new property has been added called syncTimers. Events are emitted on all tabs by default and leader election has been reduced down to the leaderElection prop and the isLeader method. This results in a more simple API surface and less type ambiguity. It is disabled by default.Īll of the rest of the options from v4 have been set to sane defaults. This is how you enable or disable the Cross Tab Reconciliation feature. Now in v5, the crossTab prop only takes a boolean. ![]() In v4, the crossTab prop use to take a boolean or an object of configuration options. All the edge cases have been solved and the API surface has been reduced to the essentials. It is now much smaller and more specialized for this particular use case. The Cross Tab feature has been rewritten from the ground up. A guide on how to do that can be found here. You can use the higher order component to create the IdleTimer component if you wish and it would be a drop-in replacement for the v4 component. It has been replaced with the withIdleTimer higher-order component. The major change in v5 is the removal of the IdleTimer component. Breaking Changes # Removal of Component # Only new features and improvements to existing ones. Just a setTimeout() function set for 10 seconds with a result of alert.If you are upgrading from v4 there are a few breaking changes that you should take into account. This is our redirecting function, nothing complicated. We are going to use id later, while reseting the timeout. You might be wondering, what does id variable do? This variable is going to store information about our setTimeout(). This basic setup allows us to get going! 2. Mine are going to look something like this. Hello fellow programmers! In this short tutorial I’m going to explain how to detect idle time using JavaScript! This can be really useful, when it comes to idle redirection or fetching some data whe user is inactive.
