Suppose I have surfaced an LWC as a custom tab in a Lightning application by using the <target>lightning__Tab</target> in the metadata file. The LWC has some state. If I navigate away to another tab (for instance, a custom object tab) and return to the LWC tab, the state is still there. However, neither renderedCallback() nor connectedCallback() fires on the LWC when returning to the tab. Is there a good way to detect that the user came back?

One use case is wanting to reset some state.

  • Did you ever figure out how to do this in a console app? I am looking to detect when user activates different tabs within Service Console. I am happy to create an LWC for this but not sure how to detect the different tab clicks. Thanks!

Answering myself after some help from others!

Applying NavigationMixin, importing CurrentPageReference, and doing the following allows me to detect it.

@wire(CurrentPageReference)
setCurrentPageReference(currentPageReference) {
    console.log('Welcome to the tab ' + (new Date().getTime()) );
}

  • did you have to implement a LWC to navigate to your LWC tab to achieve this?

  • @KrisGoncalves when I was testing this, I tested by 1. Click LWC tab. 2. Click custom object tab. 3. Click LWC tab again. Never did anything meaningful with this - it was simply for a proof of concept based on a student question.

    So I now see this does work in standard apps, but it doesn't seem to work in console apps (which is what I was using). Might create my own question. Thanks!
